OpenNebula Reviews & Product Details

OpenNebula platform helps us build & manage VM instances & Kubernetes clusters. It provisions a shared environment for both VMs and K8 clusters so that we can overview both workloads in a single pane of glass. It also manages the orchestration of front-end master nodes of the cluster & its infrastructure requirements. Review collected by and hosted on G2.com.

Its knowledge base requires focus since there are many complications while working with K8 clusters. It would be great to offer more details on its features & best practices so that we can pick up its platform quickly. Apart from this, we are good with services provided by the OpenNebula platform for VM deployments & cluster management. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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.

For me it's been the ease of use and reliability of the system. Installation and setup of our initial hosts were straight forward and then from there the ability to scale up across the infrastructure we created with such speed was definitely miles ahead of OpenStack (our first attempt at a private cloud) at the time of setup.

Our aim has been to have our own AWS type infrastructure alongside it. Review collected by and hosted on G2.com.

I think there's some work to do with managing configuration of underlying hosts. It would be nice to have a faster route to scaling up and provisioning interfaces.

Flexibility, extensibility, simplicity and clean-cut design fit for purpose. Easy to deploy and manage. Excellent community. Scales nicely for small to mid-range deployments (hundreds of hosts, thousands of virtual machines). Provides interfaces for beginners and advanced users. Can be used for data center management as well as private cloud deployments. Review collected by and hosted on G2.com.

Won't scale as well for very large deployments (thousands of hosts, tens of thousands of virtual machines). Rudimentary user management, ACLs and simplistic approach to authentication (not necessarily a problem, depending on the deployment environment). Misuses MySQL for document-centric data (XML) which impacts performance, data integrity and DB scalability. Review collected by and hosted on G2.com.
