Existing Portal Servers
• Require a single Portal Administrator to manage the available portlets– Including deployment, test, etc
• Require Portal Developers to write HTML, JavaScript AND Java, C#, VB, etc– Not a pure “web” solution– Require more expensive and harder to find skills
• Not designed with SOA model in mind• Complex and heavyweight
