This highly practical 3-day class on Comet and HTML 5 Web Sockets and Server-Sent Events (SSE) for Real-time Web applications was designed by Kaazing's Jonas Jacobi, CEO and co-founder of Kaazing corporation. This course will teach you how to create next generation real-time Web 2.0 solutions, using HTML 5 Web Sockets and SSE that work today.
Come and learn about Comet architecture, HTML 5 Web Sockets and SSE. 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 and GPS Tracking Applications
- Sports and News Broadcasting Applications
Upon completion of this course you will know how to create your own scalable, real-time Web applications with the latest HTML 5 standards-based technologies.
