Some time ago Oracle Cloud Infrastructure introduced features around autoscaling and instance pools. This in short means you have an instance pool which uses image from the instance configuration you have defined. Instance pool has minimum number of instances you want to keep running and with autoscaling you can add scaling out or in depending…
Series – Get your database running with Terraform part 9: Database
At this point I have created everything else apart from the database. For the database we have few options starting if we would like to have Baremetal, Virtual Machine or Exadata.

We hadn’t done any resizing lately so I think issue had been there already but for whatever reason it wasn’t noticed. For backing up and rolling back on OS updates Exadata takes snapshot on identical LVM volume as the…
