Read full review 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.
Read full review Pros Low-cost solution Open-source Engaged community Solid documentation Is a very reliable tool for orchestration with good usability Read full review 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. Read full review Cons Sometimes you can find undocumented bugs that can compromise the entire infrastructure. [If] you don't have an official support channel, you have try to find out the source of the problem by yourself. Volume size limitation. Other players allow you to create volumes up to 64TB while ACS allows only 2TB volumes Read full review 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.

Now a days the university is delivering IaaS for all staff, students, teachers and researchers, they are using these resources to delivery services to their clients and have a great results in research area
Read full review Only because of low cost & zero licensing of Red Hat OpenStack
Read full review Return on Investment Low-cost solution (free and open-source) More than 2000 users using it simultaneously Stable and reliable Up and running since 2012 Read full review 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. Read full review ScreenShots
