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

"Nutanix is a company that cares about your experience and your thoughts and improving things."
"On the cost management side, we realized it has a stronger ROI, being very cost-effective, with pricing models beneficial for multi-cloud environments, quantifying to a 425% three-year return on investment, a 21% higher developer productivity, and 88% less planned downtime."
"What I appreciate about Nutanix Cloud Manager (NCM) is that it gives us a good, simple view that really plays effectively when we're trying to talk to other teams to show them their VM has too many resources."
"Overall, we've gone from deploying workloads in 45 minutes or 90 minutes and we've taken that down, in some cases, to seven minutes."
"I really like the Nutanix Marketplace a lot. We publish standard workloads there and that, in combination with the Projects, allows for self-service, which is the most powerful feature of Calm."
"The most valuable aspect of NCM is its ease of deployment."
"The scalability of the solution is way better than anything else, and everything is plug-and-play, which is pretty awesome."
"The ability to cross between different clouds is a valuable feature of Nutanix Cloud Manager Intelligent Operations."
"OpenNebula is lightweight, stable, and easy to customize."
"The service feature appeals most to us, thus it is the most valuable."
"For the entire data center, as a private cloud, I believe that user management, expert management, and the virtual data center is completely magic for the users."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"It's easy to integrate OpenNebula with our IT systems."
"The solution provides templates for configurations that can easily be exchanged to VMs."
"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."
 

Cons

"They should include more use cases for automation in administering the environment."
"I would appreciate improvements in handling pre-check failures for beginners, particularly compatibility mismatches and issues with unsupported driver versions during upgrades or patches."
"We are probably the customer who has the least number of problems. However, costs are always a concern."
"If you're still running tiered architecture for the storage, it would be good to give stats on the amount of data that is warehoused in the cold tier versus the hot tier."
"However, I feel that simpler onboarding and learning curves are needed as some users find the initial setup and configuration planning requires expertise."
"There is room for improvement in making the solution easier still. If you don't know Calm, it's not so easy to use... It is a really good solution for doing simple tasks, but it's not a good solution for complex tasks."
"I would appreciate more advanced networking features in the dashboard."
"The stability of the Prism solution is another thing that we have found to be a bit of work. For example, the Prism Central and the appliances use 97 percent of the CPU and RAM of the virtual machine."
"Template management also needs improvement in OpenNebula because it's inferior right now."
"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."
"The UI, monitoring, and alerting could benefit from further improvements."
"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."
"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."
"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."
"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."
 

Pricing and Cost Advice

"Nutanix costs more than Hyper-V, but the price is reasonable for the features we're getting. We have better support, analytics, reporting, and other capabilities that we didn't have before. That is more than enough to justify the cost. The hardware we purchased from Nutanix was priced fairly. The primary costs are software and support. It's a subscription-based service, which can be bad or good, depending on how you look at that. For me, it makes perfect sense. We get regular updates and can get support when we need it."
"The solution is expensive."
"You will see great value from it if you utilize the self-service part of Calm. The price you pay for it will only give you equal value if you use the self-service part to enable other teams. If you only use it as a deployment mechanism, I think it's rather expensive."
"Prism Pro is a bit more upfront. It costs a bit more for some of the features that you get. We have four clusters, and two of them don't have Prism Pro because they weren't even available with what we bought. Those two clusters also run well, but they don't have all the features."
"Some people say that Nutanix is a bit more expensive. However, when we were looking at Nutanix versus Cisco and NetApp before deploying this solution, the prices were very similar. Being a government entity, we got a bit more of a discount on Nutanix so it was a bit cheaper. The time savings after the fact has been really worth it."
"The company frequently changes its prices, and it is not clear how the subscription-based model works."
"Licensing is always a hot topic. We haven't had any challenges around licensing and costs. Everything was within budget and our expectations. It's a hot topic because renewals and licensing costs are high. Managing costs is always a concern, as we're always being asked to do more with less."
"At the end of the day, the product justifies the cost, and it leads to a conversation with management over whether we actually need this feature and if there are any use cases for why we would want to keep it."
"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."
"VRA is very expensive but OpenNebula is free."
"The solution is open source so is free."
"OpenNebula gives good value for money."
"We use the Community Edition, rather than the Enterprise Edition."
"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."
