Executive SummaryUpdated on Jun 15, 2025

OpenNebula and VMware Tanzu Platform are competing products in the cloud management and application infrastructure space. VMware Tanzu Platform seems to have the upper hand due to its comprehensive features and advanced capabilities.

Features: OpenNebula is valued for its flexible infrastructure, ease of use, and integration capabilities, making it suitable for managing hybrid and multi-cloud environments. VMware Tanzu Platform offers strong support for microservices, Kubernetes integration, and robust security features, allowing advanced application development on a wider scale.

Room for Improvement: OpenNebula could improve by expanding its feature set to include more advanced security options and better Kubernetes integration. Enhancing scalability for large enterprises and streamlining the customization process would also be beneficial. VMware Tanzu Platform can improve by simplifying its deployment process to make it more accessible for smaller enterprises, reducing complexity for new users, and offering more competitive pricing options for smaller deployments.

Ease of Deployment and Customer Service: OpenNebula provides a simple deployment model with a focus on quick setup and personalized customer support, making it attractive for small to medium enterprises. VMware Tanzu Platform offers extensive deployment capabilities fitting enterprise-scale needs, but it may require a more complex initial configuration. Both platforms deliver reliable customer service, though OpenNebula is often seen as offering a more tailored approach.

Pricing and ROI: OpenNebula typically presents lower setup costs and favorable ROI for smaller-scale deployments, emphasizing affordability. VMware Tanzu Platform involves a higher initial cost yet potentially offers greater ROI in large-scale environments, with pricing reflecting its extensive capabilities.

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.

Quotes from Members

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

Pros

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

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

"OpenNebula is lightweight, stable, and easy to customize."

"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."

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

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

"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."

"For the entire data center, as a private cloud, I believe that user management, expert management, and the virtual data center is completely magic for the users."

More OpenNebula pros

"I have multiple Kubernetes environments within my environment. TMC gives me a single pane view, which is good for managing everything."

"We feel very good about these features."

"The most popular feature of VMware Tanzu Mission Control is its graphical user interface for describing network policies on the Service Mesh, which is highly integrable with other tools commonly used in supply chains such as security."

"VMware Tanzu Mission Control has many valuable features, such as ease of use and customization."

"Tanzu Mission Control has quite a set of rich features when compared to OpenShift."

More VMware Tanzu Platform pros

Cons

"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."

"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."

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

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

"The front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."

"There are no payment gateways in OpenNebula."

"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."

"An area for improvement in OpenNebula is the number of features it has. The solution doesn't have that many cloud features compared to other solutions. You'd say, "Okay, simplicity over a rich feature list?" Some say, "No, I need a big machine or a cloud interface for my customers to manage resources. I don't have to go and do it for them." Some people do it that way, and it works, but I'd like to improve the limited features in OpenNebula."

More OpenNebula cons

"The network control and security policies must be improved."

"LYNX is a managed cluster solution that takes care of specific details within a cluster, such as sequences or services. I haven't seen this feature in Tanzu Mission Control."

"The solution could improve by having better integration with other solutions such as HPE."

"The solution's initial setup process was complex...The solution could benefit from improved customization and visibility for its users."

"The price is very high compared to other Kubernetes environments because Kubernetes is open source."

"The solution is currently focused on VMware infrastructure and I would like to see more options made available."

"We want to see a new feature that helps build more security architecture like Zero Trust Security or shifting left in Kubernetes."

"VMware Tanzu Service Mesh could add better integration with other cloud platforms, such as vRealize Automation or VMware vCloud Director for cloud providers."

More VMware Tanzu Platform cons

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."

"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."

"OpenNebula gives good value for money."

"VRA is very expensive but OpenNebula is free."

"The solution is bundled in with Cloud Foundry so the pricing is not independent."

"There are different licenses available. You have to upgrade your license if you want to scale the solution more."

"Since we were at a large data center, the price might not have been a concern for us."

"The least expensive licensing cost for VMware is around $350 per core."

"I would recommend that businesses look into the full price for their requirements. The price is high, but there are some open-source add-ons that can be used for customization while keeping costs down, although these might not be suitable for everyone."

"One of our Spanish customers told us that VMware Tanzu Service Mesh is a very expensive product for their data center."

"VMware Tanzu Mission Control is cheaper than Red Hat OpenShift."

"The solution is only for large or medium size enterprises because it is expensive."
