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

"It has enabled us to decrease the optics by around 55 to 60%."
"OpenNebula is lightweight, stable, and easy to customize."
"OpenNebula freed my customer from doing the maintenance operations of the servers because now that can be done by his clients."
"The most valuable feature of OpenNebula is that it scales very well."
"OpenNebula has given us tremendous knowledge about cloud computing and about Cloud Management platforms, commonly known as CMP."
"It makes maintenance very easy and stress-free for our teams."
"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 is quite easy to deploy."
"The multi-tenancy with the VCD is great."
"We feel very good about these features."
"The solution is integrated very well with a lot of other systems. Also, its GUI is very good."
"A feature we find valuable is that other products can also be integrated with Mission Control. This means that we can see the status of specific clusters, as well as view the monitoring application logs all from one point."
"The Tanzu platform is highly available, scalable, and flexible."
"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."
"We never experienced any problems with scalability."
"Tanzu Mission Control has quite a set of rich features when compared to OpenShift."
 

Cons

"The storage feature that they have is a bit confusing."
"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."
"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."
"The protocol for clusterization is rough and doesn't work well."
"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."
"There are no payment gateways in OpenNebula."
"The web interface could be better. It's not very difficult to use, but there's room for enhancement."
"The product should support integration with Google Cloud Platform (GCP)"
"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."
"VMware Tanzu Service Mesh could add better integration with other cloud platforms, such as vRealize Automation or VMware vCloud Director for cloud providers."
"The price is very high compared to other Kubernetes environments because Kubernetes is open source."
"Another area of improvement is pricing."
"The solution's initial setup process was complex...The solution could benefit from improved customization and visibility for its users."
"One potential area for expansion would be leveraging AI capabilities, which my customer might be interested in exploring as they grow."
"Tanzu could provide more granular control over whatever networking is being done on the containers."
 

Pricing and Cost Advice

"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."
"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."
"The solution is open source so is free."
"We use the Community Edition, rather than the Enterprise Edition."
"VMware Tanzu Mission Control is cheaper than Red Hat OpenShift."
"The price of VMware Tanzu Mission Control is greater than that of Red Hat's competitor solution"
"One of our Spanish customers told us that VMware Tanzu Service Mesh is a very expensive product for their data center."
"The license for VMware Tanzu Application Service is expensive. The license should be cheaper."
"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 licensing cost is expensive."
"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."
