This depends on whether we have experience configuring the new application being hosted, or not. WebLogic by itself is simply an application hosting architecture. But most application deployments are not as simple as visiting an online store and clicking an Install button. WebLogic is not what I would recommend for quickly standing up a proof-of-concept beta application. But when architecting a solution for hundreds, thousands or millions of users, it's perfectly suited.

We do deployments roughly once a week, three times a month. 

We have our own in-house developed deployment manager, which we call the Deployamater, and they set up all the deployments. The manager fetches the EARs, JARs, pages, and JSP files, then it deploys them. 

We don't use the automated deploying via Oracle. We manage it like that, but we do it in an offline environment. 

We duplicate our environments and we go to our offline environment, deploy there, test it first, and then switch the traffic to the new environment that it's being deployed to.

We did the implementation ourselves with our in-house team.

We are the vendor and implement the solution for our customers. My advice would be to get yourself on one of the administration workshops that Oracle provides or self-teach on YouTube. Talk to a partner in your area as they can provide you with workshops and training.

I have implemented it both through a vendor team and through our in-house team.

We manage one of the instances ourselves, and the other one is outsourced to a third-party in the US.

A vendor set up the solution on our behalf.
