Overall Satisfaction with Red Hat OpenStack Platform

I support TelcoCloud datacenters which are managed by Red Hat OpenStack. This cloud infrastructure hosts multiple Telco applications, known as Virtual network functions (VNFs) & All the VNFs are created & managed by the OpenStack platform only. This use case has saved a significant amount of CAPEX for telecom operators by converting the traditional hardware-based applications in the form of VNFs. Operations & maintenance tasks are also easy now.
  • Scaling of application components (VMs).
  • Managing the networking between virtual machines.
  • Management of VNFs & the underlying infrastructure.
  • Availability & uptime of VMs because of features like VM migration & evacuation.
  • User management really needs improvement - when compared to AWS or GCP.
  • Security of the overall platform needs to be improved.
  • The whole architecture needs to be modular which is not. Ex - Upgrading any particular component (nova, neutron, cinder) should be possible without upgrading the whole Red Hat OpenStack version.
  • The creation of HEAT templates for complex applications is still a challenge & has a dependency on external tools.
  • Stack creation still requires parameters modification at controllers & compute because of the complex nova-scheduler algorithm.
  • Low cost.
  • SDN functionality.
  • Easy scaling of VMs.
  • Saved CAPEX for sure (I can't quote a figure).
  • Saved Opex also - because a large support community is already available.
  • Increased complexity of system setup though.
Only because of low cost & zero licensing of Red Hat OpenStack

Do you think Red Hat OpenStack Platform delivers good value for the price?


Are you happy with Red Hat OpenStack Platform's feature set?


Did Red Hat OpenStack Platform live up to sales and marketing promises?

I wasn't involved with the selection/purchase process

Did implementation of Red Hat OpenStack Platform go as expected?


Would you buy Red Hat OpenStack Platform again?


Best suited for - any organization where you have people who already have expertise on OpenStack, Linux & IP networking. Otherwise, the maintenance & operations will be difficult. When the number of deployed VMs reaches its capacity, it becomes very difficult to manage Red Hat OpenStack because there are no in-built fault management & performance management tools available within Red Hat OpenStack.

Not suited for - Organizations where people have a culture of working on automated GUI-based tools. Here VMware wins over Red Hat OpenStack. Also where you have mission-critical applications where downtime cannot be tolerated.
