Deploying bandwidth-efficient Ajax applications does not guarantee that the service levels in a Service Level Agreement will stay high. No matter how well you change code in the Ajax format to make it more bandwidth efficient, there will be always risks and vulnerabilities you'll need to watch out for and mitigate. Regular developerWorks author Judith Myerson gives a brief Ajax recap, shows what Web services vulnerabilities are and why Service Level Agreements (SLA) are important, and suggests some solutions for speeding up Ajax applications.
This DeveloperWorks article covers AJAX concepts such as vulnerabilities (excessive bandwidth, corrupted data, frequent small requests, and memory leaks), SLAs, and improvements.
Improvement topics include speeding up applications, web services standards, and traffic monitoring.
