Ottomatica slim vs VMware vSAN: What are the differences?

Ottomatica slim: Build and run tiny vms from Dockerfiles. It will build a micro-vm from a Dockerfile. It works by building and extracting a rootfs from a Dockerfile, and then merging that filesystem with a small minimal kernel that runs in RAM; VMware vSAN: Enterprise-class, storage virtualization software. It is enterprise-class, storage virtualization software that, when combined with vSphere, allows you to manage compute and storage with a single platform. You can reduce the cost and complexity of traditional storage and take the easiest path to hyperconverged infrastructure and hybrid cloud. Evolve to an integrated hyperconverged infrastructure (HCI) solution with vSAN to improve business agility, all while speeding operations and lowering costs.

Ottomatica slim and VMware vSAN belong to "Virtualization Platform" category of the tech stack.
