The WebSocket protocol is used to enhance the experience of using websites, such as chat applications, collaboration, games and immediate push updates. But the web is not the only place where you will find WebSocket in use. They are commonly used to allow microservices to communicate with each other, to stream telemetry data and a variety of machine to machine communications.
- [Instructor] The WebSocket protocol is used…to enhance the experience of using websites,…such as chat applications, collaboration, games,…and immediate push updates.…But the web is not the only use of WebSocket.…It is commonly used to allow microservices…to communicate with each other…and a variety of machine-to-machine communications.…Let's have a look at some of these common usages.…So what are the used cases for the WebSocket protocol?…Apart from those already discussed,…and many new and fun uses…have already been found for this technology.…They include activities like telemetry data streams,…financial exchanges provide a view into their data,…often via website, but also in desktop applications,…and nearly all of the exchanges…offering this service use WebSocket protocol…to provide the live financial data streams.…
Almost everything you see that has a live data element to it…is transported over the WebSocket protocol.…So the change in data that traders see in the graphs…are supported with data from the WebSocket feed.…
Join Alex Theedom as he guides you through the lifecycle of a WebSocket connection, and discusses the Java EE WebSocket programming methodologies: annotation and programmatic. He shows how to secure and encrypt WebSocket endpoints and use simple techniques to test their implementation. In addition, he explains how to integrate the JSON-processing API and build a front-end and server based WebSocket client.
