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 live migration feature has been great and is something we use very often."
"OpenNebula is lightweight, stable, and easy to customize."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"The service feature appeals most to us, thus it is the most valuable."
"The solution provides templates for configurations that can easily be exchanged to VMs."
"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."
"It's easy to integrate OpenNebula with our IT systems."
"OpenNebula freed my customer from doing the maintenance operations of the servers because now that can be done by his clients."
"The support from VMware is very good."
"I have multiple Kubernetes environments within my environment, and TMC gives me a single pane view, which is good for managing everything."
"The solution is integrated very well with a lot of other systems. Also, its GUI is very good."
"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 initial setup is easy."
"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."
"We feel very good about these features."
"The most valuable feature of the solution is the ability to check the flow of all the different variants within our applications."
 

Cons

"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."
"The UI, monitoring, and alerting could benefit from further improvements."
"The front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."
"The protocol for clusterization is rough and doesn't work well."
"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."
"The web interface could be better. It's not very difficult to use, but there's room for enhancement."
"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."
"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."
"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."
"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 network control and security policies must be improved."
"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's initial setup process was complex...The solution could benefit from improved customization and visibility for its users."
"The infrastructure is quite challenging."
"The cost is a major factor in this solution; anything above the standard version comes at a high price."
 

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."
"We use the Community Edition, rather than the Enterprise Edition."
"The solution is open source so is free."
"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."
"Since we were at a large data center, the price might not have been a concern for us."
"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."
"There are different licenses available. You have to upgrade your license if you want to scale the solution more."
"One of our Spanish customers told us that VMware Tanzu Service Mesh is a very expensive product for their data center."
"The licensing cost is expensive."
"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."
