## OpenNebula Reviews
  ### 1. Enhancing OpenNebula with OpenVZ containers support

**Rating:** 3.0/5.0 stars

**Reviewed by:** Dariusz C. | Senior Java Developer, Computer Software, Small-Business (50 or fewer emp.)

**Reviewed Date:** January 09, 2016

**What do you like best about OpenNebula?**

The great thing about OpenNebula is its simplicity. Comparing to other private IaaS solution that are open-sources (for instance OpenStack, CloudStack) it is much simpler to install and maintain. Similarly, due to its  simply, plugin-based architecture developing a custom hypervisor driver was a breeze.  The same applies to web console - it is clear, elegant and undoubtedly matches the latset UX trends.

**What do you dislike about OpenNebula?**

Sadly, the above-mentioned simplicity of OpenNebula doesn't mean that it is an elegant product. It surely has a lot of rough edges. For instance, its security mechanisms leaves a lot to be desired: requirement for a passwordless sudo account, CLI configuration stored as a plaintext. Besides, we found out that there are some 'hacks' in platform's core engine just to support some specific technology stack that should be rather provided as a well-though plugin mechanism.

**Recommendations to others considering OpenNebula:**

If you need a simple to use IaaS platform and have a small amount of compute nodes (i.e. hypervisors) to maintain pick OpenNebula. In more complex deployment you should probably consider more advanced but at the same time complex soltuions.

**What problems is OpenNebula solving and how is that benefiting you?**

We tried to leverage OpenVZ containers as a hypervisor in a IaaS platform. We choose the lightweight virtualization as it is more promising in terms of resource usage and efficiency. It is more suited to needs of creating a Platform-as-a-Service solution on top of IaaS what was focus of our work. We picked OpenNebula as a IaaS platform of our choice because we found that its learning curve is much more tempting than in other IaaS platforms available (OpenStack, CloudStack).
