FOURES Jean-Philippe - PeerSpot reviewer
Products Manager at a tech services company with 501-1,000 employees
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.

Cloud Infrastructure Engineer at Safaricom Ethiopia plc
Has supported container-based deployments and improved infrastructure visibility through monitoring tools
Aria Operations, formerly known as VMware vRealize Operations, has been renamed to vROps. We are currently using this for monitoring purposes. For orchestration, we are using VCD to automate Telco Cloud. VCD is an automation tool, and we are also using VMware Tanzu Platform for the Kubernetes environment, alongside TKG, Tanzu Kubernetes Grid. These are also other solutions for the Tanzu Kubernetes environment. For Telco Cloud, we are using it to automate our company's operations, which is for a telecom company. We are familiar with these products, especially vCenter, ESXi, VCD, vCF, and vROps. It is very easy to integrate applications when we deploy vCenter and ESXi since we can enable vSphere with Tanzu feature. We can build namespaces and provide application developers the platform to deploy their applications on pods within containerization. We can easily manage, pull results, and create containers efficiently, making it a simple way to handle applications. We provide namespace labels for application developers, and we can manage their resources along with other aspects easily. Regarding security, we use many tools such as CDX and LDAP, AD for integrating our Kubernetes cluster with the developer teams. We can manage roles and permissions simply. It is very straightforward to integrate with EDX and other third-party tools, Active Directory, to the Kubernetes cluster, allowing easy access and management.

Quotes from Members

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

Pros

"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."
"The live migration feature has been great and is something we use very often."
"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."
"The service feature appeals most to us, thus it is the most valuable."
"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."
"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."
"We can build namespaces and provide application developers the platform to deploy their applications on pods within containerization, and we can easily manage, pull results, and create containers efficiently, making it a simple way to handle applications."
"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."
"VMware Tanzu Mission Control has many valuable features, such as ease of use and customization."
"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."
"I have multiple Kubernetes environments within my environment. TMC gives me a single pane view, which is good for managing everything."
"The valuable feature I have found to be the management of Kubernetes clusters in a private cloud or public clouds, such as Azure or Google Cloud Platform."
"A feature we find valuable is that other products can also be integrated with Mission Control. This means that we can see the status of specific clusters, as well as view the monitoring application logs all from one point."
"We never experienced any problems with scalability."
 

Cons

"They should add more features like object storage."
"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."
"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 storage feature that they have is a bit confusing."
"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."
"The UI, monitoring, and alerting could benefit from further improvements."
"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."
"The implementation is not easy, it is very complex and can take a day or two to complete."
"Cost is always a concern. Smaller companies might find the price a bigger issue."
"The solution could improve by having better integration with other solutions such as HPE."
"Having a unified dashboard to manage all infrastructure, whether it involves additional IT infrastructure or modern apps, would be highly advantageous"
"One potential area for expansion would be leveraging AI capabilities, which my customer might be interested in exploring as they grow."
"The disaster recovery feature could be improved to provide better tracking of issues. I would also like to see the introduction of a dashboard view, for even further integration of all the areas that Mission Control looks at."
 

Pricing and Cost Advice

"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."
"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."
"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."
"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."
"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."
"The license for VMware Tanzu Application Service is expensive. The license should be cheaper."
"The price of VMware Tanzu Mission Control is greater than that of Red Hat's competitor solution"
"VMware Tanzu Mission Control is cheaper than Red Hat OpenShift."
"The licensing cost is expensive."
"The solution is bundled in with Cloud Foundry so the pricing is not independent."
