Best of this Week Summary 12 January - 19 January 2009

• A couple of tips on Building Super-Scalable Web Systems with REST. All the client wanted was a getLocalWeather webservice for their 10M+ users website. At first it was implemented with a regular (MS WCF) webserivce, but for scalability they switched to resource-based REST.
  


• How to get rid of the Javascript splash screen in Oracle ADF Faces 11g Rich Client, and how to reduce the initial Javascript download size on the first page in an ADF application. Described is a currently undocumented feature that sets Context Parameters in web.xml, performing compression and only downloading the Javascript that is needed on the current page. Amazing for such an essential element to be an undocumented feature, because the default complete ADF RC Javascript libs can be up to 2M in size.
  


• A post with a summary of points on the question how secure cloud computing is. Quite related to my own recent tutorial on setting up an Amazon AMI with Java and MySQL on EBS using the AWS Management Console.
  


• Interesting white paper which "presents an overview of the architecture and configuration of the Sun Blogs web site, a blogging service dedicated to Sun employees worldwide. It also provides usage statistics and information about the system administrator's experience managing one of the busiest externally facing Web 2.0 site deployments at Sun".
  
  "Blogs.sun.com is powered by Sun Java™ System Web Server 7.0 Update 2 (hereafter, Web Server) running on a pair of Sun Fire™ T2000 servers with UltraSPARC® T2 processors. The site also uses a custom version of the open source blogging server Apache Roller Weblogger Version 4.0.0.12 (http://rollerweblogger.org/project/), MySQL™ database server, and Memcached. The service is integrated with Sun's secure single sign-on identity system backed by a worldwide employee LDAP directory for authentication and authorization."
