Reliable, simple to manage, and offers great technical support

The support of VXLAN fits with our network management. Thanks to this we can propose mixed solutions using virtual resources on OpenNebula and bare metal servers hosted in our facilities linked to each other on the sale network. This use case is very useful when some applications need bare metal power (Kubernetes workers, huge databases, AI models computations, et cetera). The cluster management is very useful for splitting our different clusters (mutual vs dedicated). We can manage deployments and capacity planning without pain. The API is also really simple and it helped us to develop the Terraform provider to manage OpenNebula like any other cloud infrastructure.

Everything can be visibly managed, scheduling and state management features are pretty good

We've integrated it with source control management tools like GitLab and Bitbucket. The scheduling and state management features are pretty good using Spacelift. It integrates with tools like Terraform and Kubernetes for policies, but we haven't worked on the compliance part. Spacelift streamlines collaboration among our development and operations teams. We use it for CI/CD as well. It can handle automation strategies. Whenever you put your YAML files and integrate them with Spacelift, it will scan the code and show where you need to make changes.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The ability to use it almost like a public cloud for an organization is a big asset, as it will create a value proposition and can control costs in a great way."

"The service feature appeals most to us, thus it is the most valuable."

"It makes maintenance very easy and stress-free for our teams."

"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."

"With a single click, we could set things up and initiate them."

"I also like the ability to build custom functions. I can define a function where I have two types of views and configure the dependencies. The virtual data centers concept allows me to define users. If a user wants to join certain kinds of machines, the host and the other user won't see them. It gives me the flexibility to define multiple views and data centers in one place."

"What's best about OpenNebula that people like is that it's easy to deploy. It's also easy to manage. It's interesting because people choose OpenNebula over other solutions because of the ease of management."

"The most valuable feature of OpenNebula is that it scales very well."

More OpenNebula pros

"One key feature is the Spacelift policies, which we can attach to deployments to ensure compliance with our standards."

"A valuable feature of Spacelift is that you can attach labels, and it is a modernized tool for infrastructure deployments. It is pull request-based, and you can see all the Terraform plan and apply logs on the pull request itself, which is not available across any other CI/CD tools."

"I appreciate that I just have to connect to my AWS account with my credentials, and Spacelift handles the rest."

"Spacelift is like an extension of Terraform, where everything can be visibly managed."

"Knowing the HashiCorp Configuration Language (HCL) makes it easier to use without issues."

Cons

"They should add more features like object storage."

"There are no payment gateways in OpenNebula."

"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."

"The UI, monitoring, and alerting could benefit from further improvements."

"Hosting platforms are limited so the deployment process needs improvement."

"They have been saying for the past two and a half years that they would develop a feature to hot-add RAM and CPU, but it does not work."

"The web interface could be better. It's not very difficult to use, but there's room for enhancement."

"Most of the competitors are offering some sort of billing software to transform their installation to work as a small-sized public cloud, but those offerings from OpenNebula are still missing."

More OpenNebula cons

"Spacelift currently lacks features that can help with complex type deployments and coordination for major deployments."

"Synchronization can be difficult when using older and newer versions with Kubernetes and HashiCorp."

"In the free version, there's no straightforward way to be notified once a deployment is finished."

"If you are a small enterprise organization, below 500 people, I would not recommend it."

"The self-hosted version does not have a lot of features compared to the SaaS version, such as cloud integrations for Azure and GCP."

Pricing and Cost Advice

"The licensing for OpenNebula used to be free, but now it's no longer free. A customer contacted me asking to move to another provider because of the changes in the licensing terms for OpenNebula. I have no information on how much the OpenNebula license is because the customer pays for it, and I only do the integration."

"We use the Community Edition, rather than the Enterprise Edition."

"OpenNebula gives good value for money."

"VRA is very expensive but OpenNebula is free."

"The solution is open source so is free."

"OpenNebuoa has recently come up with a new subscription model that is economical and a lot of new customers are choosing this as it is an easy subscription model."

"It is a bit expensive product."

Terraform Integration: Seamless compatibility with Terraform for robust infrastructure management.
GitOps: Automates change detection from GitHub, ensuring efficient workflows.
Compliance Policies: Helps maintain infrastructure within regulatory guidelines.
