WebSocket, a new tool component for web developers, allows developers to create web apps without the hassles of HTTP. With all the obstacles encountered in the web app development process, most developers resort to developing makeshift communication libraries to bypass them. It’s hard to break old habits, but if you still need convincing, here are 5 major benefits to using WebSockets.
1. Delivers Full Duplex Communication Model for the Web WebSockets deliver communication between the client and server in both directions simultaneously. Prior to WebSockets, developers had to find a way to simulate full duplex communication by using a technique called polling and long-polling. But these techniques do not actually provide true duplex communication. In other words, data cannot be transferred between the server and client simultaneously. HTTP was not designed for this. This is where HTML5 sockets come into play.
2. Increased Client and Server Communication Effieciency Traditionally, web apps required your users to establish a connection to a back server using an overhead of HTTP servers. Just two WebSocket frame bytes can replace hundreds of HTTP header bytes. Normally a large number of users face resource contention if they have to connect to your back-end server. WebSockets enable developers to reduce a large number of unnecessary network throughput at a rate of 1000:1. Through continual polling, latency is dramatically reduced.
3. Avoid Siloed Solutions for Individual Subsystems Legacy systems house TCP–based services. These are used to connect end users to back-end resources for information in web applications. The problem is that many applications are designed with many subsystems that use their own individual app protocols. WebSockets eliminate siloed solutions in each subsystem. 4. Easy to Use API Like most developers, you probably rely on platforms such as Microsoft Silverlight, Java, or JavaFox to create dynamic web apps. You also probably have difficulty connecting these rich clients to real-time data. HTTP limitations are difficult to get past, so to bypass this problem developers resort to creating their own side communication libraries. WebSockets help you prevent this time-consuming practice by offering a single interface for app development. In other words, you not only save time in developing, but you also eliminate the need for custom development on any of your apps.
5. Open Full Duplex Connection Over the Web If your SOA products work well on your internal network, be prepared to navigate through a matrix of firewalls and proxy servers to get your SOA up and running on the web. Without WebSockets this is a nightmare waiting to happen. WebSockets simplifies this process by using an Enterprise Service Bus or web-based Supply Chain to extend messages from SOA’s within a firewall to an external SOA.
