WebRTC – Brief Introduction

Web Real-Time Communication is an open-source set of protocols or APIs that help developers create real-time communication web or mobile applications for voice, video, or messaging. Developers use these APIs to establish a peer-to-peer connection between the browser or application without integrating plugins or downloading software.

When was WebRTC created?

Google created WebRTC in 2011, which underwent a standardization process with the Internet Engineering Task Force (IETF) and the World Wide Web Consortium (W3C) to ensure platform interoperability. Over time, major web browsers have adopted and implemented support for WebRTC, including Microsoft Edge, Mozilla Firefox, and Google Chrome.

What are the features of WebRTC?

WebRTC offers robust features that help developers design and develop real-time communication web and mobile applications. The features of WebRTC real-time communication are:

  • Peer-to-peer communication – Allows browsers or applications to connect directly without plugins or middle servers.
  • GetUserMedia API – Gives users access to audio and video streaming devices, like microphones and webcams.
  • Data Channel – Allows peer-to-peer connection with arbitrary data type.
  • Cross-platform compatibility – Major web browsers support WebRTC, which includes Microsoft Edge, Mozilla Firefox, and Google Chrome.
  • Adaptive Bitrate Control – Adjusts the quality of the audio and video streams based on the network conditions.
  • DTLS and SRTP – Encryptions used in WebRTC to ensure security and privacy.

What are the benefits of WebRTC?

Should I buy or build a WebRTC solution?

Buying or building a WebRTC solution depends on your business requirements. Businesses, especially those looking to move quickly and efficiently, prefer buying a WebRTC solution. Buying a WebRTC solution can offer numerous benefits, like faster deployment, lower initial costs, and high reliability. However, it can limit you when looking to improve or add new features.

On the other hand, building your own WebRTC solution can be a key investment, offering you flexibility, control, and customization. Although it might be expensive and require technical expertise, the long-term benefits of owning and controlling your application architecture are more important. Developing and hosting your WebRTC solution on your server ensures that it aligns perfectly with your business needs. It provides a secure, scalable, and high-performing platform for real communication.

Challenges in using cloud-based WebRTC solution

Implementing a cloud-based WebRTC solution is cost-effective, however, it comes with its own set of challenges. It restricts you from making customizations and other configurations which can limit the growth of your business.

Some of the primary challenges in using cloud-based WebRTC solutions are:

  • Limited scalability – Handling large volumes of users requires sophisticated traffic management strategies and load balancing. In cloud WebRTC solutions, dynamic resource allocation is limited, and fluctuating demands can’t be met. As the number of users grows, ensuring low latency and high-quality media streams is challenging.
  • Latency and network issues – The level of latency can vary based on the location of the users. It can affect the quality of communication. Inconsistency in the network and limitations in bandwidth can decrease the user experience. You can not optimize the network path and minimize delays with cloud-based solutions.
  • Security and privacy – As you are not hosting the application on your server, ensuring end-to-end encryption to protect sensitive information is difficult. You can not implement any methods in the solution to prevent unauthorized access and secure user identities.
  • Quality of service – Varying network conditions make maintaining audio and video quality challenging. The audio and video quality cannot be dynamically adjusted with an adaptive bitrate algorithm in cloud WebRTC solutions. You can develop and implement strategies to handle packet loss, jitter, and other network issues.
  • Server infrastructure – You do not have control of the server. It restricts you from deploying and managing STUN and TURN servers for NAT transversal. You cannot choose the location of servers to minimize latency and maximize performance. You can not monitor server performance or maintain infrastructure.

Benefits of hosting a WebRTC solution on your server

Building and hosting your WebRTC solution on your server allows you to create a tailored solution that aligns seamlessly with your requirements. While it might require a higher investment, the benefits of control, security, and flexibility are great, especially for businesses with performance and regulatory needs.
