I came across some good info about the difference between two major Iaas provider Openstack and VMware. So thought of sharing with this blog. Couple of differences are as follows.
VMware Pro/Cons
Pro –
- Feature rich (vSphere HA, vMotion, DRS, I/O control).
- Very large ecosystems.
- All os vendors make it supported and certified under ESXi.
- ESXi can be downloaded and used Freely.
Cons –
- Per core license – expensive.
- Proprietary platform.
- ESXi can not be APIs accessed – need to buy licenses.
Openstack Pro/Cons
Pro –
- Probably the most successful example of Open Source project after Linux.
- Support from many OEMs and OS vendors.
- Interoperability with many components, just pick your favorite one and plug it in.
- Standard and well accepted APIs.
Cons –
- Very complex to setup and troubleshoot.
- Although common codebase, might differ from implementations.
- Need high numbers of management nodes.
- High skills required to run the Cluster.
