Developing real-time engagement applications where users interact with each other using live audio, video, and text is a really complex challenge. It requires a lot of time and effort to build out the infrastructure and logic to support these features. The biggest challenge is to have your infrastructure be reliable, scalable, and low latency to deliver the best user experience.

At Agora, we’re solving this problem for developers at scale. Agora’s Software-Defined Real-Time Network™ provides the broadest range of coverage throughout the world (200+ countries), while delivering high-quality with ultra-low latency (400ms or less). To make leveraging the Agora platform easy for developers we offer easy to use SDKs for Android, iOS/macOS, Windows, Web, Electron, Flutter, React Native, Unity and more. With our SDKs you can build and deploy your real-time engagement application in a matter of hours instead of days.

Getting back to the topic for this blog, how does one build a video conferencing app with Agora and React? Agora recently announced a new beta SDK for React. We’ll look at how it works with a simple demo app.

Getting Started

Creating an Account with Agora

• Sign up for an account and log in to the Agora Console.
• Navigate to the Project List tab under the Project Management tab
• Create a project by clicking the blue “Create” button.
• When prompted to use App ID + Certificate, select App ID only.
• Retrieve the App ID, which will be used to authorize your requests while you’re developing the application.

Note: This blog does not implement token authentication, which is recommended for all RTE apps running in production environments. For more information about token-based authentication in the Agora platform, see this guide.

Setting up a React Project

The source for this project is available on GitHub, you can also try out a live demo.
To follow along, scaffold a React project using Vite:

1. Ensure that you have installed Node.js LTS and NPM.
2. Open a terminal and execute npm create vite@latest agora-videocall — — template react-ts
3. This creates a folder named “agora-videocall”
4. Navigate to the project: cd agora-videocall
5. Install the dependencies: npm i agora-rtc-react agora-rtc-sdk-ng
6. You can start a dev server by running npm run dev

Time to Code

We’ll start in the App.tsx file. Since this demo is going to be really simple, we’ll create all our components in the same file. Let’s start by importing the dependencies we’ll use in our application.

import { useState } from "react";
import { AgoraRTCProvider, useJoin, useLocalCameraTrack, useLocalMicrophoneTrack, usePublish, useRTCClient, useRemoteAudioTracks, useRemoteUsers, RemoteUser, LocalVideoTrack } from "agora-rtc-react";
import AgoraRTC from "agora-rtc-sdk-ng";
import "./App.css";

The Agora React SDK provides a set of hooks and components to manage the state of your application and to render the video call interface.
In our App, let’s initialize a client object from the Agora SDK and pass it to the useRTCClient hook. The client object represents the local user in the video call. Passing the object to the useRTCClient hook makes it available to the rest of the application (and hooks) by using a React Provider. We’ll add this in a bit, first, let’s set up our application state:

const App = () => {
  const client = useRTCClient(AgoraRTC.createClient({ codec: "vp8", mode: "rtc" }));
  const [channelName, setChannelName] = useState("test");
  const [AppID, setAppID] = useState("");
  const [token, setToken] = useState(null);
  const [inCall, setInCall] = useState(false);

• channelName: Represents the name of the channel where users can join to chat with one another. Let’s call our channel “test”.
• AppID: Holds the Agora App ID that we obtained before from the Agora Console. Replace the empty string with your App ID.
• token: If you’re using tokens, you can provide one here. But for this demo we’ll just set it as null.
• inCall: A Boolean state variable to track whether the user is currently in a video call or not.

Next, we display the App component. In the return block, we’ll render an h1 element to display our heading. Now, based on the inCall state variable, we’ll display either a Form component to get details (App ID, channel name, and token) from the user or display the video call:

return (
    <div style={styles.container}>
      <h1>Agora React Videocall</h1>
      {!inCall ? (
        <Form
          AppID={AppID}
          setAppID={setAppID}
          channelName={channelName}
          setChannelName={setChannelName}
          token={token}
          setToken={setToken}
          setInCall={setInCall}
        />
      ) : (
        {/* Videocall here */}
      )}
    </div>
  );
};

To create the video call component, let’s first wrap it with the AgoraRTCProvider component, this accepts a client returned from the useRTCClient hook and makes it accessible down the tree. You should add this at the top level of your video call.
We’ll create a <Videos> component next, to hold the users’ videos, passing it our props from before. We’ll also display an End Call button that ends the call by setting the inCall state to false:

return (
    <div style={styles.container}>
      <h1>Agora React Videocall</h1>
      {!inCall ? (
        <Form
          AppID={AppID}
          setAppID={setAppID}
          channelName={channelName}
          setChannelName={setChannelName}
          token={token}
          setToken={setToken}
          setInCall={setInCall}
        />
      ) : (
        <AgoraRTCProvider client={client}>
          <Videos channelName={channelName} AppID={AppID} token={token} />
          <button onClick={() => setInCall(false)}>End Call</button>
        </AgoraRTCProvider>
      )}
    </div>
  );
}

export default App;

Video Component

We destructure the props to access the AppID, channelName and token.
The Agora React SDK also gives you useLocalMicrophoneTrack and useLocalCameraTrack hooks, these create and set up the local microphone and camera tracks respectively. Since the process to create these tracks is asynchronous they also give you a loading and an error state along with the tracks.

function Videos(props: { channelName: string; AppID: string; token: string }) {
  const { AppID, channelName, token } = props;
  const { isLoading: isLoadingMic, localMicrophoneTrack } = useLocalMicrophoneTrack();
  const { isLoading: isLoadingCam, localCameraTrack } = useLocalCameraTrack();

We can use the useRemoteUsers hook to access the other (remote) users that join our video call. This hook gives you an array of objects, each object represents remote users in the call. The array is like your React state that gets updated each time someone joins or leaves the channel, we’ll use this to render our UI and keep it in sync with the form of the call:

 const remoteUsers = useRemoteUsers();

We can use the usePublish hook to publish the local microphone and camera tracks. You can pass in an array of tracks you want to publish to the channel, these tracks can be subscribed and viewed by other users who join the same channel.

 usePublish([localMicrophoneTrack, localCameraTrack]);

To start the call we need to join a room or a channel. We can do that by calling the useJoin hook and passing in the AppID, channelName, and token as props.

useJoin({
    appid: AppID,
    channel: channelName,
    token: token === "" ? null : token,
  });

We can access the remote users’ audio tracks with the useRemoteAudioTracks hook by providing it the remoteUsers array. This hook automatically handles subscribing and unsubscribing to the user tracks as your component is mounted and tracks are available.

const { audioTracks } = useRemoteAudioTracks(remoteUsers);

To listen to the remote users’ tracks, we can map over the audioTracks array and call the play method for each available track:

 audioTracks.map((track) => track.play());

We’ll check if either the microphone or the camera is still loading and render a simple loading message:

const deviceLoading = isLoadingMic || isLoadingCam;
  if (deviceLoading) return <div style={styles.grid}>Loading devices...</div>;

Once the tracks are ready, we can render a grid with videos of all the users in the channel. We can render the user’s own (local) video track using the LocalVideoTrack component from the SDK, passing it the localCameraTrack as the track prop:

return (
    <div style={{ ...styles.grid, ...returnGrid(remoteUsers) }}>
      <LocalVideoTrack track={localCameraTrack} play={true} style={styles.gridCell} />
      {/* Remote videos here */}
    </div>
  );
}

We can display the remote users’ video tracks using the RemoteUser component. We’ll iterate through the remoteUsers array, passing each user as a prop to it:

return (
    <div style={{ ...styles.grid, ...returnGrid(remoteUsers) }}>
      <LocalVideoTrack track={localCameraTrack} play={true} style={styles.gridCell} />
      {remoteUsers.map((user) => (
        <RemoteUser user={user} style={styles.gridCell} />
      ))}
    </div>
  );
}

These components are unopinionated so you can style them as you like.

That’s all the code we need to build a video conferencing app with Agora and React. Here’s what the final code looks like:

function Videos(props: { channelName: string; AppID: string; token: string }) {
  const { AppID, channelName, token } = props;
  const { isLoading: isLoadingMic, localMicrophoneTrack } = useLocalMicrophoneTrack();
  const { isLoading: isLoadingCam, localCameraTrack } = useLocalCameraTrack();
  const remoteUsers = useRemoteUsers();
  const { audioTracks } = useRemoteAudioTracks(remoteUsers);

  usePublish([localMicrophoneTrack, localCameraTrack]);
  useJoin({
    appid: AppID,
    channel: channelName,
    token: token === "" ? null : token,
  });

  audioTracks.map((track) => track.play());
  const deviceLoading = isLoadingMic || isLoadingCam;
  if (deviceLoading) return <div style={styles.grid}>Loading devices...</div>;

  return (
    <div style={{ ...styles.grid, ...returnGrid(remoteUsers) }}>
      <LocalVideoTrack track={localCameraTrack} play={true} style={styles.gridCell} />
      {remoteUsers.map((user) => (
        <RemoteUser user={user} style={styles.gridCell} />
      ))}
    </div>
  );
}

Form and styling

For the sake of completeness, here’s what the Form component looks like:

function Form(props) {
  const { AppID, setAppID, channelName, setChannelName, token, setToken, setInCall } = props;
  return (
    <div>
      <p>Please enter your Agora AppID and Channel Name</p>
      <label htmlFor="appid">Agora App ID: </label>
      <input id="appid" type="text" value={AppID} onChange={(e) => setAppID(e.target.value)} placeholder="required"/>
      <br /><br />
      <label htmlFor="channel">Channel Name: </label>
      <input id="channel" type="text" value={channelName} onChange={(e) => setChannelName(e.target.value)} placeholder="required" />
      <br /><br />
      <label htmlFor="token">Channel Token: </label>
      <input id="token" type="text" value={token} onChange={(e) => setToken(e.target.value)} placeholder="optional" />
      <br /><br />
      <button onClick={() => AppID && channelName ? setInCall(true) : alert("Please enter Agora App ID and Channel Name")}>
        Join
      </button>
    </div>
  );
}

As a cybersecurity professional, you know the significance of foreseeing attacks, identifying issues, and fortifying a defence. You are capable of program management, planning, and analysis. You have the knowledge, qualifications, and experience required to complete the task. But what if the performance of the personnel of the enterprises and organizations you assist in protecting depends on their actions? You must be able to connect with them.

A cybersecurity team must explain to these individuals the significance of recognizing potential cyber dangers. In cybersecurity, having a strong IT team is very important. Businesses that have not made investments in cybersecurity are at a significant risk. Your capacity to defend them against cyber dangers depends on your skill, knowledge, and intelligence (IQ).

However, emotional intelligence (EQ) is crucial as you collaborate to educate your clients’ enterprises about cyber-attacks and the essential defences. Your emotional intelligence (EQ) reflects how well you can control your emotions and comprehend those of others. Your team dynamic will be enhanced, and you’ll perform better in the cyber battle by raising your EQ. Here are five ways that improving your EQ will benefit you.

Improve Team Motivation

IT specialists are needed by businesses and organizations for more than just cybersecurity. For cybersecurity, they want a group of enthusiastic IT specialists. You are aware of the value of your work. You are aware that ransomware attacks leave crucial enterprises incredibly exposed.

These assaults serve as a constant reminder of how valuable you are. You and your group maintain the required systems. Every business you service relies on you for both defence and offensive. You must possess motivation. Sure, learning to code effectively is crucial, but gaining a high EQ can boost your confidence and keep you interested in finding solutions and preventing problems.

You are inspired to progress when actively involved in your task. Being driven makes you more alert and prepared for anything. Your company’s brand is set when everyone on the team is motivated.

Boost Morale

The morale of your workforce fosters self-motivation. The impact of EQ improvement on your mentality is one way it might boost morale. Low self-esteem is correlated with low morale. Gaining emotional intelligence skills and increasing self-awareness also boosts your confidence. Businesses you guard look at their defensive team for both intelligence and confidence.

You frequently collaborate with others. Morale has an impact on people. To explain to staff members why it’s crucial to develop strong passwords, for instance, requires effective cybersecurity people skills. Employees are typically the first line of protection against cyberattacks. They must be vigilant for viruses, attentive when handling passwords, and skilled at spotting phishing emails.

They will benefit from your team’s work and your positive attitude as they strive to succeed. You’ve undoubtedly spent money on schooling and certifications to improve your ability to accomplish your work. If you make an investment in raising your EQ, the reward will be considerably higher. You can enrol in coaching or read about techniques to improve your emotional intelligence and increase your success. 

Help Find Weak Areas

One of the cornerstones of emotional intelligence is self-awareness. You will be a valuable addition to any firm and to your team if you can recognize your shortcomings, the vulnerabilities of your team, and the weak spots in a company’s defence. Working on your EQ helps you develop that emotional muscle on a personal level to use in the workplace. 

Provide Conflict Resolution

Any team will inevitably experience conflicts, especially in high-stress industries like cybersecurity. If you focus on your emotional intelligence, you’ll be able to function more effectively under pressure independently and in a team 

Gain the Trust of Companies and Organizations

Businesses rely on you to impart knowledge and assist in constructing a defence that safeguards them so they can focus on what they do best. It’s true that people are more interested in how much you care than how much you know. Another component of a high EQ is empathy. When you establish an emotional connection with someone, they will trust you more.

If you suppress your emotions in formal contexts, it could be challenging to accomplish this. The secret is to develop the ability to express the right emotions at the right time without letting them control you. Being empathetic shows those you work with that you care about your work and their problems. You can increase your reputation as a trustworthy cybersecurity expert by doing so.

Final Thoughts

High-IQ people frequently underestimate their emotional intelligence. You will work better with your team and provide better services to businesses if you improve your EQ. For example, you can raise your EQ by reading or enrolling in coaching. A high EQ will help in increasing motivation, boosting morale, spotting problem areas, settling disputes, and fostering trust. To become a better leader and cybersecurity professional, you should put time into raising your emotional intelligence (EQ).

As organizations increasingly embrace Continuous Integration/Continuous Deployment (CI/CD) methodologies to accelerate software delivery, security in these environments becomes a paramount concern. 

The fast-paced nature of CI/CD pipelines can inadvertently introduce significant vulnerabilities, exposing software systems to potential cyber threats.

To mitigate these risks and safeguard critical assets, adopting secure coding practices is crucial. In this article, we delve into the best practices for fortifying CI/CD pipelines against threats and vulnerabilities, empowering development teams to build and deploy software with security at its core.

Understanding the Risks in CI/CD Environments

Common Threats and Vulnerabilities in CI/CD Pipelines

1. Code Injection Attacks

Code injection attacks, including SQL injection and Remote Code Execution (RCE), are among the prominent risks in CI/CD environments. If not appropriately addressed, malicious actors can exploit vulnerable code to tamper with data, execute unauthorized commands, or gain illicit access to critical systems.

OWASP Top 10 reports that code injection remains a concerning issue, accounting for 19% of reported vulnerabilities in web applications.

2. Insecure Dependencies and Libraries

CI/CD pipelines often rely on third-party libraries and dependencies to streamline development. However, libraries that are not up-to-date or from unverified sources might contain potential vulnerabilities that could be exploited by malicious individuals.

3. Insider Threats and Privilege Escalation

Insiders with access to the CI/CD pipeline can inadvertently or maliciously introduce vulnerabilities. Privilege escalation is a concern when users are granted excessive permissions, enabling unauthorized actions within the pipeline. According to a recent Insider Threat Report, 68% of organizations experienced insider attacks in some form, emphasizing the importance of robust access controls.

4. Configuration Issues and Secrets Exposure

Misconfigured CI/CD tools and environments may inadvertently expose sensitive information, such as passwords and API keys, to unauthorized parties. 

5. Lack of Security Testing and Monitoring

Failing to incorporate security testing and monitoring in CI/CD pipelines can result in undetected vulnerabilities and prolonged exposure to threats. A recent survey revealed that only 40% of organizations conduct security testing throughout the development lifecycle.

Secure Coding Best Practices for CI/CD Pipelines

Code Review and Static Analysis

1. Importance of Peer Code Review

Peer code review is a fundamental practice in CI/CD environments to identify and rectify potential vulnerabilities early in the development process emphasizing the importance of CI/CD security from the outset. Studies show that peer review can detect up to 60% of defects and significantly reduce the number of security issues in software.

2. Utilizing Static Code Analysis Tools

Security sit in early-stage software development can be significantly enhanced by leveraging static code analysis tools. Static code analysis tools automatically scan the source code to identify security vulnerabilities and coding errors. The use of such tools can reduce the number of security defects by up to 85%.

Implementing Proper Authentication and Authorization

1. Secure Access Control Mechanisms

Robust authentication mechanisms, such as multi-factor authentication (MFA) and strong password policies, bolster the security of CI/CD pipelines against unauthorized access attempts.

2. Role-based Access Control (RBAC) 

RBAC ensures that users have the appropriate permissions based on their roles, limiting their access to only necessary resources within the CI/CD pipeline.

3. Least Privilege Principle 

Adhering to the least privilege principle grants users the minimum level of access required to perform their tasks, reducing the potential impact of a compromised account.

For example, a CI/CD pipeline administrator is given only the necessary permissions to manage the pipeline infrastructure. This limits the scope of an attacker who gains access to the administrator’s credentials, minimizing the potential damage.

Managing Dependencies and Third-Party Libraries

1. Regularly Updating Dependencies: 

Regularly updating third-party libraries and dependencies helps to patch security vulnerabilities and ensure the use of the latest features.

2. Validating and Verifying the Integrity of External Libraries

Ensuring the authenticity and integrity of third-party libraries before integrating them into the pipeline safeguards against supply chain attacks.

3. Using Trusted Sources and Repositories

Relying only on reputable and trusted sources for third-party libraries reduces the likelihood of introducing malicious code.

Instead of downloading libraries from random websites, developers should use official repositories and package managers like npm, Maven, or PyPI, which are more secure and continuously monitored for vulnerabilities.

Secrets Management and Configuration

1. Storing Secrets Securely 

Storing sensitive information, such as API keys and passwords, in secure, encrypted storage systems prevents unauthorized access.

2. Encryption and Decryption of Sensitive Data 

Encrypting sensitive data in transit and at rest ensures that even if intercepted, the information remains unreadable to unauthorized entities.

3. Techniques to Avoid Hardcoding Credentials

Avoiding the practice of hardcoding credentials directly into the code helps prevent accidental exposure.

For example: A developer utilizes environment variables or configuration files to pass sensitive data to the application during runtime, reducing the risk of accidental leakage through version control systems.

Security Testing and Quality Assurance

1. Incorporating Security Testing in the CI/CD Pipeline

Integrating security testing tools into the pipeline enables continuous security checks throughout the development lifecycle.

For example: A CI/CD pipeline includes automated security testing, such as SAST (Static Application Security Testing) and DAST (Dynamic Application Security Testing), to detect and address vulnerabilities early in the development process.

2. Automated Vulnerability Scanning 

Automated vulnerability scanning tools help identify security weaknesses in software components, improving overall security posture.

Before each deployment, the CI/CD pipeline automatically runs a vulnerability scanner to identify any known vulnerabilities in the application’s dependencies and libraries.

3. Fuzz testing and Penetration Testing

Fuzz testing and penetration testing help identify potential weaknesses and security flaws by simulating real-world attack scenarios.

Conclusion 

Securing CI/CD pipelines through robust coding practices is not just a choice; it is imperative for modern software development. As evidenced by the prevalence of code injection attacks, insider threats, and insecure dependencies, the risks faced by organizations today are both persistent and dynamic. 

To stay ahead in the cybersecurity landscape, organizations must integrate secure coding practices at every stage of the CI/CD pipeline. By conducting peer code reviews, utilizing static code analysis, enforcing proper authentication and access controls, and managing dependencies with care, teams can significantly reduce the attack surface. 

By recognizing the vital role secure coding plays in ensuring the integrity and confidentiality of software, organizations can foster a culture of security awareness among developers.

Setting up a new Raspberry Pi Board can be daunting without a monitor and keyboard, Once you flash a new image of the Operating System – Raspberry Pi OS or similar, the next obvious step is to boot the Pi, log in to it and access the terminal over SSH. But for a headless setup, i.e. without a Monitor and Keyboard, it’s not that straightforward. The same goes if you’re using a lite image of the OS (without a Desktop Environment). For SSH to work, you first need to get your board on your home network, even if you manage to create an ad-hoc network between your Pi and workstation, the SSH is disabled for security reasons. 

Are you ready to influence the tech landscape too? Take part in the Developer Nation survey and be a catalyst for change. Your thoughts matter, and you could be the lucky recipient of our weekly swag and prizes! Start Here

There are two simple ways to sort this out, and we’ll look into it one-by-one 

#1 The Simple Way: Using the official Raspberry Pi Imager, 

Raspberry Pi’s official flashing utility can be downloaded from here . This tool allows you to pick the OS image you want to flash. It also has a setting page where you can enable SSH and add credentials of your home router WiFi SSID and password. All this information is baked into the OS image during the SD card flashing process.

#2 The Ninja Way: Underneath the hood 

While the Raspberry Pi Imager way works pretty straightforward, for the ninja user, it’s important to understand how this all works underneath the hood. So the job of the flasher programmer is to partition your SD card into two segments – BOOT and the Root File System (rootfs) of the raspberry pi. This is how typical how Linux distributions are stored. 

The boot partition holds all the essential files used during the booting process, including the bootloader, and the rootfs partition holds the primary filesystem of the Linux operating system. Now let’s add settings for our WiFi connection and enable SSH on the raspberry pi board the ninja way. 

Once you flashed a new operating system, the SD card shall be auto-ejected, so re-insert the SD card, and you shall see a partition named BOOT mounted on your system. Create a new file in the root folder of the boot partition with the exact name – wpa_supplicant.conf. In this file add following using your favourite text editor or terminal: 

“` code-block

This information shall be used by “wpa_supplicant”, a utility used by Linux distributions like Debian to connect to wifi networks. After the boot is complete, it’ll scan for WiFi networks nearby and connect to your SSID and password you supplied. 

Don’t worry about supplying your password in plain text, after the boot, this file will be removed automatically.

Now to enable SSH, which is disabled by default for security, just create a new empty file with the name ssh in the root directory of the boot partition. Use the terminal command to create this file 

And that’s it, your raspberry pi will be connected to your WiFi network and ready to accept incoming SSH connection requests, and all this is done without ever connecting your board to a monitor and keyboard – Headless. 

Test your SSH connection from your workstation open the terminal, and type:

and you shall be logged in.

 Currently, there are 6.9 billion people with access to smartphones and at least some form of internet worldwide. This means that, when developing an app, you have a potential audience of well over 80% of humankind.

Now, while it’s unrealistic to expect any app to pull these numbers (even Instagram is used by “just” 2.35 billion), the tipping point past which your app can no longer function as before is far closer than you assume.

To make matters worse, it takes just a couple of (very) dissatisfied users to ruin your rating and leave enough bad reviews to ruin your app’s reputation. This is why you must ensure that your app is scalable and resilient. Here are the top six strategies to help you with that.

1. Horizontal scaling

When structuring your servers, vertical scaling makes the most sense. After all, upgrading the server, you’re already using or starting with an impressive server (the one that gives you room for growth) is intuitive. The problem is that this system is not the most reliable. Instead, horizontal scaling, where you add more servers instead of improving a single one, might provide you with more value.

Horizontal scaling is impressive because it will allow you to withstand much higher traffic. For an app developer, having more users is the optimal end goal, so not having a plan for success simply makes no sense.

Horizontal scaling improves performance, and it’s much more cost-efficient. Adding a server sounds expensive, but it offers you flexibility and simplicity. After all, you can add more servers as you go. This means you don’t have to start too ambitious (like with vertical scaling). 

Most importantly, you have the privilege of isolating services from one another. This way, you gain a lot of resilience because a flaw, a failure, or an attack on a single service won’t compromise the rest. This also makes troubleshooting a lot easier.

The biggest challenge of horizontal scaling is achieving data consistency; however, there are more than a few ways to overcome this. 

2. Work on load balancing

Previously, we’ve talked about the imperative of working on multiple servers. Without load balancing, this would be like having five rooms in a home and spending 90% of the time in a single one. With the help of load balancing, you can evenly distribute this and get the most out of the servers you’re using.

There are numerous load-balancing techniques:

• Hardware load balancers: This is the simplest form of load balancing since it relies on having a device that distributes traffic when it reaches a certain load.

• Software load balancers: This is a part of the application stack. These are virtual machines that act in a similar way to hardware load balancers.

• Content delivery networks: A content delivery network is located in different locations. This caching service is scattered across the globe to provide you with an even higher service resilience. 

The best thing about load balancing is that it’s incredibly scalable. This is why the sooner you start doing this, the better results you will face. When your audience outgrows your current capacity, you can provide consistent performance across peak hours. 

More importantly, load balancing boosts the availability of your application. This means that, in the scenario where one of the servers falls, your app will not be completely unavailable. You’ll try to avoid this worst-case scenario at any cost.

3. Use mobile IP proxy in research and testing

As a web developer, you have to do a lot of research. Now, some of this research will be unavailable due to geographical restrictions. This is why you must use a mobile IP proxy while researching.

While doing research, you’re assuming a role of a customer, which means that various competitor platforms you’re researching target you based on your history. Because your research patterns may take you to the most unexpected places, the experience you get when you try to emulate the customer experience will be all but authentic.

It’s also worth mentioning that mobile IP proxy helps you avoid being blocked or flagged. Some platforms will do this if you make too many requests, which is sensible from their standpoint but may seriously slow down your research. 

Then, there’s the issue of load testing and scalability. You need to see how the platform will behave when accessed through a different IP, especially one using a different locale. This way, you test whether the experience provided by your app gives a consistent experience.

Finally, you can avoid captchas and bot detection measures by rotating IP addresses. Sure, this is not a huge problem, but it’s a slight annoyance that you can easily bypass with the right approach. 

4. Embrace asynchronous processing

Imagine a scenario where you plan a five-course meal at a restaurant but refuse to order all the meals simultaneously. Imagine waiting until you finish the first course only to request the second, the third, and so on. It would be inefficient, waste everyone’s time and cause a massive hold-up in the operations. 

This is what synchronous processing is like. It’s a system where you make one request at a time and must wait for the current task to be completed to move to the next one. It will slow down the application process and make your audience perceive your application as slow and inefficient.

The solution is asynchronous processing, which makes all the necessary requests without waiting for previous tasks to finish. Since modern apps and servers running them can run multiple processes in the background, there’s no good reason not to use all this computing power.

The benefits of this process are numerous:

• Improved responsiveness

• Reduced latency

• Scalability

• Parallelism

In other words, you improve your app in all fields, directly contributing to a superior UX.

Most of these tasks are achieved through asynchronous APIs, background tasks, and non-blocking I/O libraries. The latter performs network communication without blocking the main application thread. 

5. Look into auto-scaling

Real-time demand will consistently change. Even in video game apps, you have peak times on servers. In the past, some games tried to handle this by adding a user queue. This is hardly a technique that would work in web applications. Instead, you must create a system with enough elasticity to handle increased traffic.

More importantly, you need a system capable of efficiently managing these resources and automatically adjusting to the increased demand.

The way this functions is quite simple – you have a system that monitors the application’s performance across all users. Instead of allowing the service to slow down during peak, the system would utilize a cloud-based environment to improve CPU utilization quickly. This can be set to happen as soon as the number of incoming requests passes a certain threshold. Even here, you need the right strategy. 

If we compared this to naval combat, it would be like firing your cannons seconds before the enemy vessel enters your range just because you know the shell will take a while to reach the target. In other words, you need to develop an in-depth understanding of your traffic patterns and create a system that will instantly respond (far quicker than a human-issued command ever could).

This way, you will get the optimal cost-efficiency, availability, and, most importantly, optimal performance.

The key, however, lies in finding the right auto-scaling triggers. The most effective ones are usually: 

• Incoming traffic

• CPU utilization

• Response time

The last one is a bit imperfect because, from a user’s perspective, it’s reactive rather than proactive. 

6. Double down on performance testing

Previously, we’ve discussed using an IP proxy to test how your platform behaves when accessed from different locations. However, this is not the only metric that you should test. You must also test the following:

• Load

• Stress

• Endurance

• Spike

• Scalability

• Volume

Besides determining the subject of your tests, you must also figure out the KPIs you’re looking into.

• Response time: The most important aspect of user experience is response time. People hate using laggy apps. Chances are that they’ll switch to an alternative, provided that there is one.

• Concurrency: Users only assess your app’s performance from their personal experience, which may vary based on the time of day when they access it. With scalable development, you’ll be able to achieve a pretty similar consistency around the clock. 

• Error rate: Does the app break often? What are the odds of requests failing? Sure, people are more tolerant of this, but if your response time is slow, restarting the app or trying again will be even worse.

In the end, you can see how these KPIs stack. A poor response time can make a critical error exponentially worse. This is why you can’t afford to ignore a single problem. 

With the right strategy, your web applications will be more scalable and resilient
