Powering the Cloud with Oracle WebLogic


Published on

This presentation discusses the concept of the Cloud, Platform as a Service, the Application Server and the Application. It then moves on to explain what WebLogic has to offer to provide the platform in the cloud to implement the PaaS. It mentions a few of the most important features in WLS that help to power the cloud.

The Snel Brothers<br />Piet Snel – provides the plot on which to build (including electricity, water, sewerage,…)<br />So you can build your own units if you want to<br />Jan Snel – provides turn-key office space from flexible building units and office furniture<br />On his brother’s plot or on your own plot<br />Simon Sneller – provides the services that your staff would have provided from the new office<br />You do not have to hire & train (& fire) people<br />Perhaps they sit in Jan’s building, possibly on Piet’s plot. Or in some unknown location somewhere.<br />You do not have to care!<br />
