"Enhancing OpenNebula with OpenVZ containers support"

What do you like best?

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?

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 the product

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 business problems are you solving with the product? What benefits have you realized?

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).

"Versatile, Straightforward and Stable"

What do you like best?

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.

What do you dislike?

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.

Recommendations to others considering the product

If you want a straight forward access to a private cloud based IaaS then we have had very few issues scaling the VM and provision side of this product.

What business problems are you solving with the product? What benefits have you realized?

Quick fire ability to scale our infrastructure as our application demands through automation.

We had a lot of spare hardware that has been put to good use, instead of gathering dust it's helping us use every ounce of spare CPU cycles where needed.

Less management through automation.

What Infrastructure as a Service (IaaS) solution do you use?

Thanks for letting us know!

"Sensible mid-scale IaaS cloud infrastructure management framework"

What do you like best?

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.

What do you dislike?

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.

What business problems are you solving with the product? What benefits have you realized?

Providing primarily HPC (High-performance computing) cloud services and prototyping environments for developers and testers. Framework also doubles as a tool for internal data center management. Excellent for environments requiring a lot of integration and customization as well as out-of-the-box deployments.
