Peter Lubber's highly practical three day course HTML5 Communication for Real-time Web applications, using Web Sockets, Server-Sent Events (SSE), PostMessage, Cross-Document Messaging and more will teach you how to create next generation real-time Web 2.0 solutions, using HTML 5 Communication which will work in today's browsers.
Come and learn about HTML5 Communication and Web Sockets architecture. With these new standards, the browser can now enjoy the first-class citizenry of network communications that has long been enjoyed by desktop applications. You will learn how to use the emerging standards to build scalable, mission critical real-time Web 2.0 applications such as:
- Trading System Clients
- Online Betting Applications
- Social Chat Solutions
- Performance Monitoring Applications
- RFID & GPS Tracking Applications
- Sports & News Broadcasting Applications
Upon completion of this course you will know how to create your own scalable, real-time Web applications with the latest HTML5 Communication technologies.
