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

"It's easy to integrate OpenNebula with our IT systems."
"It is quite easy to deploy."
"It makes maintenance very easy and stress-free for our teams."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"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."
"The live migration feature has been great and is something we use very often."
"With a single click, we could set things up and initiate them."
"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."
"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."
"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."
"The most important feature of Tanzu Mission Control is its integration with the other products, especially with ESX and vSAN. This is a strong part of Tanzu Mission Control. In other solutions, such as OpenShift or Kubernetes, you can find similar features, but they don't have similar integration. With Tanzu Mission Control, you get a total solution with only one provider. You have the integration with the infrastructure, virtualization of networking, and virtualization of storage. You have a natural integration, and you don't have the problem of integrating it with different products or providers. Sometimes, different companies have good integration, but it is not always guaranteed. For example, many years ago, Cisco and VMware were good partners in networking, but when VMware started to sell ESX, the relationship was broken. This is the problem that you can face when you are using solutions from two different companies."
"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 observability platform and end-to-end service portal provided by Tanzu are the most valuable 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."
 

Cons

"The front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."
"The storage feature that they have is a bit confusing."
"The UI, monitoring, and alerting could benefit from further improvements."
"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."
"The protocol for clusterization is rough and doesn't work well."
"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."
"There are no payment gateways in OpenNebula."
"Hosting platforms are limited so the deployment process needs improvement."
"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 infrastructure is quite challenging."
"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."
"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."
"LYNX is a managed cluster solution that takes care of specific details within a cluster, such as sequences or services. I haven't seen this feature in Tanzu Mission Control."
"The solution's initial setup process was complex...The solution could benefit from improved customization and visibility for its users."
"VMware Tanzu Service Mesh could add better integration with other cloud platforms, such as vRealize Automation or VMware vCloud Director for cloud providers."
"Tanzu could provide more granular control over whatever networking is being done on the containers. I would also like to see a slightly more detailed view of application-level tracing. I'm referring to the connections between different microservices. If they added a service-matching feature, that would be helpful for the customers to build or be more effective."
 

Pricing and Cost Advice

"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."
"OpenNebula gives good value for money."
"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."
"We use the Community Edition, rather than the Enterprise Edition."
"VRA is very expensive but OpenNebula is free."
"The licensing cost is expensive."
"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 product is not expensive, but it is not cheap."
"Since we were at a large data center, the price might not have been a concern for us."
"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."
"The price of VMware Tanzu Mission Control is greater than that of Red Hat's competitor solution"
