IT Managers Important Points

The important points for IT managers in organizations and companies to
manage infrastructure services are:
● Easy to use
● Management tools & Optional web interfaces
● Easy to find skills and support
● Entry cost and maintenance, The lower the better
● Integration with other platforms
● Other points by you

OpenStack Pro/Cons

The advantage of OpenStack by our experiences at innfinision:
● The most successful Open Source project after Linux kernel
● 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

The disadvantage of OpenStack by our experiences at innfinision:
● Very complex to setup and troubleshoot
● Although common code base, might differ from implementations
● Need high numbers of management nodes
● High skills required to run the cluster

VMware vCloud Pro/Cons

The advantage of VMware vCloud by our experiences at innfinision and
our customers advises:
● 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

The disadvantage of VMware vCloud by our experiences at innfinision and
our customers advises:
● Per core license - expensive
● Proprietary platform
● ESXi can not be APIs accessed - need to buy licenses
● Most of applications are based on Windows

carriers and large outsourcers
● VMware is for virtualization for enterprises

Skills:
● For OpenStack high-end skills required, including system and
network
● For VMware, basic system administration is needed

Expansion :
● No actual limitation on OpenStack (might be handy create different
Availability Zones)
● Max 32 physical nodes on VMware vCloud, though not
recommended

Migration:
● OpenStack any to any through built-in qemu tools
● VMware converter for P2V and other virtualization formats

Flexibility:
● OpenStack primarily created for Linux, Windows supported on the
same infrastructure
● Great guest OS support and large ecosystem on VMware vCloud

Documentation and Support:
● OpenStack active community and vendors support

Certifications:
● Certification by training companies such as Mirantis & Red Hat
● All Certifications by VMware company

Who Should Use OpenStack ?

If you are a large company or ISP with hundreds of VMs and
networks being destroyed and created daily and have budget of
having more than 15 physical nodes to start, go for OpenStack

Who Should Use VMware ?

If you need certified traditional workloads (ex: Oracle, SAP,
Microsoft Dynamics, ...) and you have money and also you want all
the point-and-click features, this is a no-brainer decision go for
VMware
