I hope you had a chance to see the keynote by Simon Crosby at Oracle Open World yesterday. The key takeaway it that the combined solution of Citrix NetScaler and the Oracle PaaS Platform provides fully transparent scalability of any PaaS application. Key integration points are:
Transparent application and infrastructure monitoring
NetScaler application visiblity enables monitoring of the application at both the infrastructure and application level.
Sensing of capacity approaching overload
NetScaler can sense when increasing load on the application is beginning to degrade application availability and performance.
Dynamic capacity management
NetScaler, in conjunction with cloud platform orchestration services, integrates with the Oracle PaaS APIs and Enterprise Manager to scale out additional application capacity.
