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

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

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

"It's easy to integrate OpenNebula with our IT systems."

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

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

"OpenNebula has very good integration with SAP Storage."

"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."

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

More OpenNebula pros

"Defining security metrics has proven beneficial for customers in maintaining a safe environment."

"There are a lot of services available in VMware Tanzu Application Service, such as databases and application servers. You have everything you need in one application and you do not need to search outside of the solution."

"It definitely gives the end customer a good overview and perspective of running applications in terms of overall workload footprint. TMC provides a very detailed description of your cloud-native application in the form of graphical visualization."

"The most valuable feature of VMware Tanzu Mission Control is the management functionality of the cluster life cycle. Additionally, the solution integrates well with other vendors, such as Velero for backups and Sonobuoy for compliance. Additionally, it works well in multi-cluster environments."

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

"The Tanzu platform is highly available, scalable, and flexible."

"The solution is integrated very well with a lot of other systems. Also, its GUI is very good."

"The Day 2 operations support is the most vital feature"

More VMware Tanzu Platform pros

Cons

"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."

"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."

"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."

"The protocol for clusterization is rough and doesn't work well."

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

"It should have a simple REST API like most other tools. It's the industry standard format. An XML-RPC API gives you an XML document that you have to convert and then do something with that. REST API endpoint provides outputs in a JSON document. I would also like to see support for user data or heat templates, which OpenStack offers, but OpenNebula doesn't have this yet."

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

More OpenNebula cons

"Customers have noticed a considerable price increase after VMware's acquisition by Broadcom."

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

"Tanzu provides better manageability as compared to OCP, but when it comes to tagging it with other products, it's a bit rigid. If I have to bring in any new product or something out of the box from a different vendor, working with Tanzu becomes a little difficult. For example, if I want to use the F5 services, I have to add one more layer of Avi, but I don't want to do that. If I have a list of the products that I want to use, such as for firewall services, with Tanzu, I will have to go through another layer, which creates complexity."

"It is not easy to build a solution with containers. It has a graphical user interface, but you need to have a lot of knowledge of Linux and how to work in the command mode. Its support can also be improved. Currently, its biggest disadvantage is that it is a new product, and the clients prefer to go for a solution that has been in the market for a long time. There are not that many people who know this product."

"The product should support integration with Google Cloud Platform (GCP)"

"I would like to see additional support for things outside of Cloud Foundry."

"Another area of improvement is pricing."

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

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."

"VRA is very expensive but OpenNebula is free."

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

"The solution is open source so is free."

"OpenNebula gives good value for money."

"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."

"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."

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

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

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

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

"The price of VMware Tanzu Mission Control is greater than that of Red Hat's competitor solution"

"The product is not expensive, but it is not cheap."
