Any new deployment typically takes weeks or months to get things ready. With PCA, the deployment provisioning is made easy; the new environment can be ready in just few hours. Thus, this will hep organizations to avoid delays in launching new deployments.

• It is a converged system, which contains integrated HW components (compute servers, networks switches, and storage) and management software plus Oracle VM. 
• It provides more flexibility to choose the required OS. 
• It is scalable as the box can be increased by one compute node, if required. 
• It has helped us to reduce Oracle licensing costs for database and applications.         

One of the benefits, like I said, it's a converged system, so that I can install a web server and my entire EBS stock. I can have my app server, web server, my Oracle Database all on that one compute node, all on that compute stack, that is.

The main advantage of the PCA is licensing, for Oracle Database. It's the main reason why companies decide to deploy the PCA, or the software it runs (OVS, OVMM). On the PCA you also have live migration, which is a huge plus.
