VMware vSAN utilizing Amazon Elastic Block Storage (EBS) is an interesting one. Being able to independently increment storage in the VMC without adding compute nodes is a feature that has been missing, until now.
Customers of VMware Cloud on AWS will now be able to scale storage independently of compute, by adding new EBS storage nodes.
