Red Hat OpenStack Platform vs. Red Hat Virtualization

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.

Red Hat Virtualization is suitable for small implementation and hosting VMs. However, when you start asking for additional features or enhancements, the engineering team is not the flexible as other engineering teams in Red Hat. It is very likely they will not accept adding features or in the best case. They wouldn't commit to a plan when it is possible to be available.

• 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.

• RHV issues/bugs can be reported via Bugzilla to RH support. The service is great and typically responds soon.
• Red Hat distribution integration is seamless as it is integrated into the kernel.
• OpenStack support enables more customized VM templates and network configuration control.

Incentivized

• 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.

Incentivized

• Documentation of RHEV needs more improvement.
• RHEV GUI needs a lot of improvements in some versions of RHEV, GUI will not work properly (shows incorrect details of VM ).
• Need fast rollout of patch releases.
• Need good linux Knowledge to manage the RHEVM.

Incentivized

Only because of low cost & zero licensing of Red Hat OpenStack

Red Hat Virtualization is the best enterprise-level virtualization software for an organization that needs cost-effective and flexible solutions for its environment. We can easily integrate RHEV with other Red Hat software like OpenStack...etc. RHEV is highly customizable software, which helps us to customize our environment. Since RHEV is an open-source tool, we can install it on any hardware. There is no proprietary dependency.

• 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.

• It has had an extremely positive impact on my overall business and has allowed me to utilize and leverage it as an offering to my clients.
• It's an extremely solid, robust, and reliable product built off of KVM Virtualization technology.
• Less expensive solution than VMware and includes more features!
