IT Managers Important Points

innfinision.netOpenStack vs VMware vCloud

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

Costs:

● For OpenStack everything is free but Some might charge for a

maintenance fee for enterprise support

● In VMware the costs contains License + Maintenance fee


Industries :

● OpenStack is for cloud management platform for large providers,

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

● VMware commercial telephone/web 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
