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

"The most valuable feature of OpenNebula is that it scales very well."
"It is quite easy to deploy."
"OpenNebula has very good integration with SAP Storage."
"OpenNebula has very good integration with SAP Storage, is easy to use, has a good UI, and is very scalable."
"It has enabled us to decrease the optics by around 55 to 60%."
"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."
"It's easy to integrate OpenNebula with our IT systems."
"I have multiple Kubernetes environments within my environment. TMC gives me a single pane view, which is good for managing everything."
"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 Tanzu platform is highly available, scalable, and flexible."
"Tanzu Mission Control has quite a set of rich features when compared to OpenShift."
"The multi-tenancy with the VCD is great."
"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."
"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."
"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."
 

Cons

"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."
"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."
"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 storage feature that they have is a bit confusing."
"The protocol for clusterization is rough and doesn't work well."
"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."
"Hosting platforms are limited so the deployment process needs improvement."
"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."
"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'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 infrastructure is quite challenging."
"VMware Tanzu Service Mesh could add better integration with other cloud platforms, such as vRealize Automation or VMware vCloud Director for cloud providers."
"The installation of VMware Tanzu Service Mesh is very complex."
"The solution could improve by having better integration with other solutions such as HPE."
 

Pricing and Cost Advice

"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."
"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."
"One of our Spanish customers told us that VMware Tanzu Service Mesh is a very expensive product for their data center."
"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."
"It is not the most expensive option, and I believe the capabilities align well with the value it provides."
"The solution is bundled in with Cloud Foundry so the pricing is not independent."
"The licensing cost is expensive."
"There are different licenses available. You have to upgrade your license if you want to scale the solution more."
"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."
