We do have access to the later generations: The [CMR]6g and then the latest
Graviton 3 instances in the C7g family.
Our (AWS’s) engineering team highly discourages the use of the a1 instance
types at this point. Can we move that to standard T4g.2xl or better yet update
that to a C6g.2xl?
I tested c6g and c7g today.
They seem to work, but subscription-manager seems to fail (some
entitlement issue). When we sort this out, it would be an easy switch,
thank you for the tip!
It sounds like we need to update the infrastructure definitions to
later versions. These next-generation instance types will definitely increase
the efficiency of the workload.
They indeed are much faster.

Some of the justification should come directly from the ec2 optimizer in
the account. We should probably take a look at the profile information
there to determine what will be the best fit cost/performance wise.
Never used ec2 optimizer. Another very good tip, thanks.
