These days DBAs are involved in all aspects of cloud setup. I have completed multiple AWS migrations from on-premises and at each level thorough knowledge is needed. With respect to security, work with app teams to setup security groups. They have good knowledge of ip addresses they use. Many times these point to specific ec2. The good thing is that you can work with your TAM to identify any gaps. As long as you have permission, you can do it. Understand the architecture and business requirements very well.
Thanks

> At our work we use AWS and initially it was a lift and shift approach for few applications and then slowly progressed towards dockerize and do things differently compared to on prem (like use snapshots for quick restore instead of rman restore and use ECS file system for sharing volumes across instances;). The DBA was responsible for the Oracle side of things and was involved only in updating security groups and creating ALB. Storage, creation of AMIs and VPC creation, IAM role creation, was done by unix admins and storage admins.

But they (the unix/storage/network) have been in that role for a longer time and could troubleshoot issues better. It is not about running few terraform scripts to provision infrastructure is what I think (which anyone can probably do).
