List,

Very recently  I came across a discussion with a banking corporation who
are  heavy users of VMware in all their Data Centre operations ..

They asked me a  lot of questions in comparison with openstack vs other
proprietary vendors (such as  VMware.   ).


As I am promoting OpenStack  I need to clarify these questions raised by
the organization.

I request your inputs for these queries .

1. Does OpenStack  support Hyper Converged Infrastructure ?
Or any HCI vendors already  with OpenStack solutions? Please share the
URL/link of case studies of OpenStack HCI.
Any documentation/Reference  to install openstack as HCI solution  with
supported H/W OEM details . I can try out ...

Yes, I have experienced with HCI by using OpenStack and Ceph.


2. Is there any performance benchmark for openstack to compare with other
such cloud stacks  ( URL/reference links kindly share )

I have done some performance test by using CBTool which is the corr of SPEC Cloud IaaS benchmark. So, so the result can be compared with published SPEC Cloud IaaS result as long it has same benchmark parameters.


3. What is the market share of OpenStack all over the world ? ( If any
statistics kindly share.)
Any survey reports available how many large and medium organizations are
using Openstack distributions for  private/public cloud use in production ?

Maybe you can refer to OpenStack surveys. It seem that on any forms (including customized), OpenStack os popular for public cloud.


4. Does OpenStack new versions support VDI(Virtual Desktop Infrastructure)
solutions out of the box.? pls give a reference link / url for the same.

Actually, VDI consists managed desktop VMs. I haven't use it but maybe Guacamole can be used for VDI on OpenStack.


5.  What is the alternative for VROPS and VRA (including self service
capabilities, Blueprint/Template based deployment) in OpenStack and any
comparative study on the capabilities available.   ( Please share inputs if
any to refer. )

OpenStack includes self service capability. Yes, it has template based deployment like Heat and catalog based deployment like Murano.


6. What is the alternative of VMWARE Network Insights and VMWARE CodeStream and Vrealize  Loginsights  in  OpenStack ?

I use other open source products for monitoring and log analysis. Somethink like Prometheus, Loki, etc.


7.  Any major capability available in VMware cloud stack for which
alternative is not available in OpenStack out of the box ?

I have no idea about this. But it is hard to have apple to apple comparison.


8.  Tools to maintain multiple OpenStack Cluster, any concept of
Supervisory cluster available

There are some cloud management products which are compatible with OpenStack. But for me, Ansible and/or BASH scripting are good enough.


9. Who all are the large organizations who deployed OpenStack as their
alternative over proprietary solutions(eg: VMware cloud and virtualization
products ..)

I have no idea with this.


10. Does OpenInfra Foundation also provide direct support For OpenStack
Deployment ?  If yes  Kindly share the link / url where to contact
/approach for paid support ? in case the clients need paid support ?

It seem OpenInfra doesn't, but OpenInfra member do. CMIIW.

11. Regarding security of cloud  environments /infrastructure, what are the
USPs of OpenStack cloud security  over other competing cloud middleware
providers ? and the vulnerability handling model/mechanism in production ?

On OpenStack, every tenants can be fully isolated. Anyway, some security products may have another approach to enhance the security. Floating IP concept is good for hiding non service (externally) instance.


Thanks in advance for your  invaluable inputs.

Each and every input from each member is valuable for me to showcase as
solid proofs to defend and promote the openstack over proprietary market
leaders.
