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.
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

"OpenNebula freed my customer from doing the maintenance operations of the servers because now that can be done by his clients."
"It is quite easy to deploy."
"With a single click, we could set things up and initiate them."
"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."
"OpenNebula is lightweight, stable, and easy to customize."
"The live migration feature has been great and is something we use very often."
"For our use case, we found the solution to be the best fit when dealing with infrastructure services."
"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 initial setup is easy."
"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 support from VMware is very good."
"We never experienced any problems with scalability."
"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."
"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."
"Tazu is a developer-friendly and highly mature product."
"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."
 

Cons

"They should add more features like object storage."
"Hosting platforms are limited so the deployment process needs improvement."
"The protocol for clusterization is rough and doesn't work well."
"The web interface could be better. It's not very difficult to use, but there's room for enhancement."
"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."
"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."
"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."
"The front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."
"The infrastructure is quite challenging."
"Tanzu is not yet a mature product, and it's not present in large environments."
"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."
"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."
"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."
"Another area of improvement is pricing."
"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."
"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."
 

Pricing and Cost Advice

"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."
"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."
"We use the Community Edition, rather than the Enterprise Edition."
"The solution is bundled in with Cloud Foundry so the pricing is not independent."
"It is not the most expensive option, and I believe the capabilities align well with the value it provides."
"One of our Spanish customers told us that VMware Tanzu Service Mesh is a very expensive product for their data center."
"There are different licenses available. You have to upgrade your license if you want to scale the solution more."
"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."
"Its pricing is very competitive. We get around 70% or 75%, sometimes even 80%, discount on the product. I would rate it a four out of five in terms of pricing."
"The license for VMware Tanzu Application Service is expensive. The license should be cheaper."
