CTO at Encha
A highly scalable solution that gives good value for money, but it does not have payment gateways
OpenNebula's templates are weak, and it could do something to make template creation a lot easier to use. The solution has a template for every single VM you create, which is not clever. You should be able to use a template for many different virtual machines. There are no payment gateways in OpenNebula.
ErmiasGirma - PeerSpot reviewer
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."
"With a single click, we could set things up and initiate them."
"The solution provides templates for configurations that can easily be exchanged to VMs."
"OpenNebula has given us tremendous knowledge about cloud computing and about Cloud Management platforms, commonly known as CMP."
"It has enabled us to decrease the optics by around 55 to 60%."
"I'll definitely recommend OpenNebula because it's an open-source solution that's effortless to set up, and the total cost of ownership is low."
"It makes maintenance very easy and stress-free for our teams."
"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 Tanzu platform is highly available, scalable, and flexible."
"The most valuable feature of the solution is the ability to check the flow of all the different variants within our applications."
"We never experienced any problems with scalability."
"VMware Tanzu Mission Control has many valuable features, such as ease of use and customization."
"We feel very good about these features."
"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."
"The observability platform and end-to-end service portal provided by Tanzu are the most valuable features."
"The initial setup is easy."
 

Cons

"They should add more features like object storage."
"Hosting platforms are limited so the deployment process needs improvement."
"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."
"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."
"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."
"I would like to see OpenNebula add more integration with REST API. XML-RPC API is good, but it becomes a pain to form a resting output."
"Addressing the high upfront costs could improve the product. Implementing a subscription-based model with tiered service options could make it more accessible to a broader range of customers."
"Having a unified dashboard to manage all infrastructure, whether it involves additional IT infrastructure or modern apps, would be highly advantageous"
"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."
"The solution is currently focused on VMware infrastructure and I would like to see more options made available."
"The implementation is not easy, it is very complex and can take a day or two to complete."
"This product doesn't have a GUI. In order to use it properly, I need to connect it to a new GUI or build a GUI to manage it — it's pretty difficult."
"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."
"The biggest gap for me was just that the solution is relatively tied to Cloud Foundry. If you have anything you need to deploy outside of that, it becomes burdensome."
 

Pricing and Cost Advice

"VRA is very expensive but OpenNebula 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."
"The solution is open source so is free."
"OpenNebula gives good value for money."
"We use the Community Edition, rather than the Enterprise Edition."
"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."
"The solution is only for large or medium size enterprises because it is expensive."
"One of our Spanish customers told us that VMware Tanzu Service Mesh is a very expensive product for their data center."
"It is not the most expensive option, and I believe the capabilities align well with the value it provides."
"There are different licenses available. You have to upgrade your license if you want to scale the solution more."
"VMware Tanzu Mission Control is cheaper than Red Hat OpenShift."
"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."
"The least expensive licensing cost for VMware is around $350 per core."
"The solution is bundled in with Cloud Foundry so the pricing is not independent."
