ONS invokes a custom application to process the image files to generate thumbnails. Store thumbnails in a NoSQL Database table.

Upload files to an OCI Object storage bucket. Every time a file is uploaded, trigger an event with an action to provision a compute instance with a cloud-init script to access the file, process it and store it back in an Object storage bucket. Terminate the instance using Autoscaling policy after the processing is finished.

You are exceeding your volume group backup quota configured.

You have the same block volume attached to multiple compute instances; if these compute instances are in different compartments then all concerned compartments must be moved at the same time.

Compute instance with multiple block volumes attached cannot move when a compartment is moved.

The Identity and Access Management policy allowing backup failed to move when the compartment was moved.

Create a policy to automatically tag a resource with the user name.

Create a policy using IAM requiring users to tag specific resources. This will allow a user to launch compute instances on\y if certain tags were defined.

Create tag variables to automatically tag a resource with the user name.

Create a default tag for each compartment, which ensure that appropriate tags are applied at resource creation

Create tag variables for each compartment to automatically tag a resource with the user name.
