Apache CloudStack vs. Canonical OpenStack

CloudStack is well suited if you want to keep the costs low and still need a reliable and robust tool to cloud virtualization orchestration. The end user interface is friendly so users can find and use functionalities quickly. Also, the newer version allows you to integrate CloudStack with external authentication using SAML for single sign-on. It can be less appropriate for an administrator that does not want to do a lot of interventions using a command line or that does not use the Linux operating system.

If you need to support diverse infrastructures then you need OpenStack. Also if you can't afford to pay costly licenses for commercial products then it is a no brainer. If you need to quickly recover for failures OpenStack will provide self healing and automatic load balancing! Don't use it if your hardware is homogeneous.

• New functionalities
• Fixing bugs
• Private and public clouds

• Very easy to use, learning curve is very short. Don't need to invest months of training before using it
• Well suited with Jenkins for automated tests
• Works well on large sets of heterogeneous hardware

• Maintenance tools
• Less command line interventions
• Server logs not so friendly
• Upgrades are not so straightforward
• The graphical interface performance in big environments can get a little bit slow

• More customizable options while choosing virtual machine configurations would be great.
• To have regular online learning sessions directly from Ubuntu OpenStack experts [to] help users and for those who implement it.
• Giving admin more control on what privileges they can grant to their users.

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

Ubuntu OpenStack has better horizontal scaling as it is designed to have open IaaS infrastructure. As Ubuntu OpenStack scales horizontally, it is designed to scale on hardware without specific requirements. Ubuntu OpenStack offers [a] rich set of services to build, manage, orchestrate, and provision a cloud with great auto scaling capabilities. Hence OpenStack administrators can be confident and relaxed in managing them.

• Minimal impact at migration from the earlier solution used (Citrix CloudPortal), once both solutions have a common kernel.
• Reduction to 0 with payment of software license.

• Lighter on initial spending for the organization.
• Deployments which have no vendor locking makes management decisions easier.
• Support from great community saved lot of time for engineers managing it.
