Manages hybrid infrastructure seamlessly with flexible cluster scaling and comprehensive oversight
The most important aspect of Nutanix Cloud Manager (NCM) is that it helps us manage the infrastructure as a hyperconverged infrastructure in HCI mode. If I have different physical servers, I can map them into a cluster and manage the storage together. It provides flexibility to make use of storage in a clustered format instead of using it in an individual storage endpoint. We have the flexibility to have Nutanix-based licensing based on the core model, instead of having a specific cost on the cluster. The costing on a core model gives customers flexibility to add multiple cores to a single physical host and adjust the infrastructure accordingly, and we can scale up the cluster as needed. While other cloud providers, AWS or Azure, are mostly into cloud-based solutions, and Azure has introduced Azure Stack HCI for managing on-premises infrastructure, Nutanix Cloud Manager (NCM) provides flexibility from day one. We can manage both on-premises and Azure solutions using a single pane of glass, eliminating the need to navigate different windows or screens. It provides a comprehensive view of the infrastructure and highlights specific areas through alerts, giving us good visibility of infrastructure conditions.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The best feature of Nutanix Cloud Manager (NCM) is Life Cycle Manager."
"NCM gives us greater insight into our infrastructure because we have more reporting and alert capabilities. We can get a breakdown of VM efficiency and determine which ones are over-provisioned, constrained, or using up too many resources in an instance."
"We use Calm's one-click self-service feature and it's really transforming the team's efficiency. The teams are used to being reactive, which is typical of what you find in IT organizations and service providers. Customers run into problems and teams react. What we're trying to do is reduce that slope and be more proactive in approach. The one-click ability is enabling us to take some of those activities and put them into operation, versus people manually responding."
"I really appreciate the console, the centralized administration, and the ability to quickly attach storage between operations."
"It is a very stable solution."
"The visibility is very nice to monitor the servers, performance, data stores, and other things. Everything is visible, and you can get the reports very quickly."
"The Nutanix technical support is very, very good."
"I like being able to expand my workload with Nutanix Cloud Manager at the best cost."
"It is quite easy to deploy."
"The service feature appeals most to us, thus it is the most valuable."
"OpenNebula is lightweight, stable, and easy to customize."
"What's best about OpenNebula that people like is that it's easy to deploy. It's also easy to manage. It's interesting because people choose OpenNebula over other solutions because of the ease of management."
"OpenNebula has very good integration with SAP Storage."
"The live migration feature has been great and is something we use very often."
"The solution provides templates for configurations that can easily be exchanged to VMs."
"The most valuable feature of OpenNebula is that it scales very well."
 

Cons

"Integration with the Nutanix Cloud Manager (NCM) Unified Storage or Nutanix cloud platform should be improved for better containerization."
"Nutanix has room for improvement around the partner tools and making them approachable and easier to learn."
"Nutanix is one of two stacks where you can run everything you like. It would be nice if you could run it without the Nutanix appliance. Some clients don't use Nutanix engineering server hardware, so it would be helpful to run the Nutanix software for demos and tests."
"They should include more use cases for automation in administering the environment."
"There's the split between Prism Central and Prism Element and having to know which interface I need to get into to do certain feature sets or just having to switch between those having all the feature sets available under for some central, area would be my biggest ask. They've been moving towards that more and more."
"Perhaps the only point I see as an improvement would be the support of multiple languages ​​in the environment. One of the few things within which I see an improvement point could be the inclusion of multilanguage in the environment."
"The interoperability with different clouds can be better so that one can even integrate the infrastructure of different clouds. They can interoperate better with other clouds because currently, you have to buy Nutanix resources in the cloud."
"Scaling with Nutanix Cloud Manager (NCM) is not as straightforward as they claim, largely due to the assumption that you have IPv6 enabled on your switches, which we did not."
"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."
"Hosting platforms are limited so the deployment process needs improvement."
"They should add more features like object storage."
"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."
"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."
"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."
"An area for improvement in OpenNebula is the number of features it has. The solution doesn't have that many cloud features compared to other solutions. You'd say, "Okay, simplicity over a rich feature list?" Some say, "No, I need a big machine or a cloud interface for my customers to manage resources. I don't have to go and do it for them." Some people do it that way, and it works, but I'd like to improve the limited features in OpenNebula."
"The protocol for clusterization is rough and doesn't work well."
 

Pricing and Cost Advice

"I think it can be more cost-effective."
"It's cost-effective. It's not necessarily cheap, but it's also not inordinately expensive. It comes down to how much you use it to offset some of the costs."
"Nutanix Cloud Manager (NCM) is cheaper than VMware and other products."
"I rate Cost Governance an eight out of 10 for pricing. There are different plans, so you can pay monthly or yearly. You can also sign a three-year contract. It's quite flexible. I can't give it a perfect 10, because customers always want a cheaper solution."
"Its licensing is cheaper than VMware. However, the price for certain licenses or use cases is not clearly indicated. For example, replication of the cluster to switch from one VM to another when one is down is not included in the standard price. It requires an additional license, but it is not clearly indicated."
"It is expensive when you are looking at small locations that need low-latency workloads, but for larger locations, as compared to other guys, even using VMware, it is not that expensive because if you add it all up, it is going to be pretty much the same value."
"For Ecuador, this is a sensitive issue. It is a small economy, so the issue of budget is very sensitive. You find many small businesses and government clients who do not renew, for example, support or guarantees, which raises the risk level for them. We are always advising them that it is necessary to renew the services or infrastructure."
"Don't unlicense your Prism licensing. Pro is the strict minimum for real infrastructure. Go with at least Pro and not with the starter. Ultimate was the best choice for me."
"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."
"OpenNebula gives good value for money."
"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."
"We use the Community Edition, rather than the Enterprise Edition."
