Course Information

About This Course

WebRTC is an open-source technology that enables real-time communication capabilities directly within web browsers and mobile applications without requiring additional plugins or software installations. It provides APIs for peer-to-peer communication, allowing audio, video, and data sharing between users. This technology is supported by major web browsers, including Google Chrome, Mozilla Firefox, Safari, and Microsoft Edge, making it a widely adopted standard for web-based communication.

With its low-latency and high-quality transmission, WebRTC is commonly used in applications such as video conferencing, online gaming, telemedicine, and live broadcasting. One of the key features of WebRTC is its ability to establish direct peer-to-peer connections, reducing the need for intermediaries like servers for media transmission. This results in lower latency, improved performance, and reduced bandwidth usage, making it an efficient choice for real-time communication.

WebRTC achieves this through various protocols and standards, including the Interactive Connectivity Establishment (ICE) framework, which helps in establishing connections even in complex network environments. Additionally, it supports Secure Real-time Transport Protocol (SRTP) for encrypting audio and video streams, ensuring privacy and security. WebRTC is built with several core components that facilitate seamless communication.

These include the MediaStream API, which handles access to a device's microphone and camera, the RTCPeerConnection API, which manages the peer-to-peer connections, and the RTCDataChannel API, which enables direct data exchange between peers. These components work together to provide a complete framework for real-time interaction, allowing developers to build applications that can support high-quality voice and video calls, screen sharing, and instant messaging. Due to its flexibility, WebRTC is widely integrated into various platforms, including social media, enterprise collaboration tools, and customer support services.

Where this course fits

Concepts behind this area

Security

Security Operations Centre (SOC)

A security operations centre is the team, tooling and process that monitors an organisation's systems for security events around the clock, triages alerts, and starts the response to those that are real.

Security

Security Risk Assessment

A security risk assessment identifies the threats to an organisation's assets, estimates how likely each is and how much harm it would do, and ranks them so that limited effort goes where it reduces the most harm.

Security

Zero Trust

Zero trust is a security model in which no request is trusted because of where it comes from, so every access to a resource is authenticated, authorised and checked against policy each time.

Networking

DHCP (Dynamic Host Configuration Protocol)

DHCP is the protocol by which a device joining a network asks for and receives an address, a subnet mask, a default gateway and DNS servers from a server, for a limited lease period, so that nobody has to configure addresses by hand.

Networking

Wireless LAN (Wi-Fi)

A wireless LAN connects devices to a network over radio using the 802.11 family of standards, through access points that bridge the wireless medium onto the wired network and enforce the authentication and encryption that the shared airwaves demand.

Networking

TCP/IP

TCP/IP is the family of protocols on which the internet runs: IP moves packets between addresses without guarantees, and TCP or UDP ride on top to deliver either a reliable ordered stream or fast unordered messages.

Hosting & Cloud

Object Storage

Object storage keeps every file as a self-contained object (the bytes, a unique key and some metadata) inside a flat bucket you read and write over HTTP, with no drive to mount and no directory tree underneath it.

Hosting & Cloud

Load Balancing

Load balancing is the practice of putting one entry point in front of several interchangeable servers and distributing incoming requests among them by a chosen policy, so that no single machine carries the traffic and no single machine's failure takes the service down.

Hosting & Cloud

CDN (Content Delivery Network)

A CDN is a worldwide network of servers that answers requests for your site from a location near the person asking, instead of sending every request back to the single machine your site runs on.
