This is a cost-effective solution because we're using the free version and we receive three databases for the price of one. The DBAs now benefit from having more databases and nobody is negatively impacted. It's a good investment. 

Database development along several parallel projects used to be nightmarish when trying to keep the various tracks of development separate in a single database. With this, it is really easy to spin up a container for each project and then combine that in a separate container as needed.

I’ve created tons of scripts for my customers to deploy databases, set up RAC instances, and Data Guard configurations. To verify such a script takes weeks and is very error-prone. Now, I’m able to set up a database once and just add pluggable databases to it with a single command. That’s incredibly useful and, in addition, there is no longer a need for virtualization as you can simply run one CDB with more than 100 pluggable databases without the need to change your hardware.

In the past it would take about five hours for us, on a weekly basis, to clone one database or one environment. Now it takes less than two hours. It saves a lot of time over the weekends. Got better things to do!

I have used it for various clients and it's been working like a breeze. Its very beneficial.

We have been working on consolidation projects. Earlier, as anybody else did, we were co-locating databases on servers, creating VMs. Now, we have moved away from that and gone to creating multi-tenant databases, so that we can consolidate. Predominately, we are using it for consolidation projects.

It's a really great new option for Database 12c. I think there's huge potential because it allows a container database to hold many pluggable databases. I love using it, even though there's not much information out there about it. People will realize how good it is at adopting databases without application changes.
