I woke up today, looked into news stream on my phone and bang! Amazon announced Arm systems being available in AWS. Nice!
Red Hat Enterprise Linux 7.6 is one of operating systems available from day one. Boots, runs and all the boring things you expect from operating system. It is nice to see new systems run RHEL out of the box.
So, what to do with such EC2 instance? I know that some people plan to move their x86-64 based cloud infrastructure to aarch64. Several projects will add them into their pool of AWS instances to have another architecture available in their CI systems. Lot of people will run one just to check how it differ from their daily x86-64 systems.
As those are not bare metal systems you are not able to run OpenStack or play with virtualization but if you are using containers (Kubernetes on Arm anyone?) then it probably can be something to play with.
