Deploying application in the cloud is a huge challenge. Typically customers either deploy various components of the application individually and then manually wire them together. Some vendors even allow you to deploy a bunch of VMs together but you still have the hard and painful job of connecting the dots. The problem gets even worse if you start to think other deployment constraints – such as which components should be co-located and which not, what should be the network topology of the application (i.e. database and middleware should be in different network segments), which components can scale out and if so how should the scale out happen.
Oracle Virtual Assembly Builder (OVAB) and Oracle Enterprise Manager 12c address this challenge. Using OVAB, application developers and architects can model the application topology graphically, define all dependencies and deployment constraints, and package the entire application in form of what we call an application assembly. These assembly can then be uploaded to the centralized software library in Enterprise Manager for self-service deployments.
At the launch of Oracle Enterprise Manager 12c last year, we talked about Oracle's plan to offer assemblies for all our products which will allow you to deploy any of our products – including packaged applications – by click of a button. Enterprise Manager has a live link back to Oracle which will notify you of the availability of new assemblies and download them if you are interested.
Last week, we made new Database assemblies available via Oracle Enterprise Manager 12c Self-Update. The release of assemblies will help customers deploy the cloud solution more easily on Oracle VM platform. Customers can create a zone of Oracle VM 3.x servers and deploy these assemblies from the Enterprise Manager 12c Self-Service interface. Following screenshot shows how they look like in the self-update interface of the Oracle Enterprise Manager 12c.
