Apache CloudStack vs. Red Hat Virtualization

Whether our clients are VPS hosting providers or operate private cloud infrastructure for their internal enterprise requirements, CloudStack provides solutions in an easy to implement and operate way that is simple to provide training for. The learning curve for our customesr adopting CloudStack for the management of their cloud infrastructure is shallow, enabling our clients to come up to speed quickly without having to outsource their administrative functions any longer than necessary

RHEV is well suited for organizations that need a cost-effective and flexible solution for their environment. As its vendor-independent software, easily install on any type of hardware. RHEV provides a GUI interface to manage the software, which makes the management of the software easier for the end-user. RHEV is best for non-production or less critical applications. RHEV can be easily integrated with other REDHAT software.

• 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.

• 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

• 1- RHVM API is pretty slow, especially after creating a VM it is not possible to retrieve the VM details (i.e VM's MAC Address) fast enough, where we need to place a pause in our Ansible Playbook, make the automation process slow.
• 2- RHV is still using collected to monitor the hypervisors which is deviating from Red Hat policy for other RHEL based applications to use PCP to monitor, which is richer in features.
• 3- It will be great if it is possible to patch the hypervisors using other tools such as satellite and not only via RHVM.
• 4- In the past Red Hat used to present patches in the z release (i.e. 4.3.z), and features in the y release (i.e 4. y), but starting from 4.4 that is mixed together wherein the Z release you get both patches and features, that is not good because that requires a lot of time to test when we patch as it includes features as well.
• 5- Engineering team has to be more reactive when new feature is requested.

The University, my first large implementation, had a big issue with 149 small data centers spread on São Paulo State, this data centers costs to university were very high, the consolidation idea in two data centers were awesome, but were worried with the management, so we adopted ACS to management of all 576 physical hosts. 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

RHEV is an excellent product, includes more features, is less expensive, and has rock solid reliability and is backed with the best Red Hat Support in the industry. RHEV uses KVM under the hood which is used by all the big players in the industry (AWS, Rackspace, etc) to lower their overall costs and improve efficiency and profits and that's why RHEV is an excellent solution!
