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.
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.

Quotes from Members

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

Pros

"It's easily expandable storage-wise and compute-wise."
"Nutanix Prism Pro has improved the way that we manage our systems due to the way that the solution is built."
"The ease of use is a valuable feature. For us, it's a consistent interface. It's very easy to train our employees on it, and it's a newer generation interface. It's homogeneous, and every product and subset tie together, giving a very similar look to everything."
"Nutanix Cloud Manager (NCM) provides flexibility from day one as we can manage both on-premises and Azure solutions using a single pane of glass, eliminating the need to navigate different windows or screens."
"We save a lot of time with Calm. It has enabled our company to develop and deploy applications faster and it has reduced the time it takes us to QA applications."
"Simplicity is most valuable because, with a single click, we have visibility of the entire infrastructure."
"Their technical support is very good."
"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."
"The live migration feature has been great and is something we use very often."
"The most valuable feature of OpenNebula is that it scales very well."
"It makes maintenance very easy and stress-free for our teams."
"For our use case, we found the solution to be the best fit when dealing with infrastructure services."
"OpenNebula has very good integration with SAP Storage, is easy to use, has a good UI, and is very scalable."
"OpenNebula is lightweight, stable, and easy to customize."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"I'll definitely recommend OpenNebula because it's an open-source solution that's effortless to set up, and the total cost of ownership is low."
 

Cons

"There are some load-balancing features that are currently missing in the flow network security and could potentially be added in the future."
"The pricing could have some changes; compared to other platforms, pricing enhancement is important, and Nutanix does enhancements quarterly."
"The machine learning can be improved. There are a lot of false positives at times. For example, I'm actually looking at some alerts right now, that some service was restarted multiple times. It is like the same alert, spammed over and over again. But really, it turns out that that event didn't happen."
"In this solution, it is difficult to organize the VM folders and subfolders."
"One thing that comes directly to mind is how they manage version control. I would love to see Calm create a built-in source control feature, one that we could tie into a repository and it would self-manage changes in versions. All the version control is built within Calm right now. I would love to see that integrated with an external repository and make it easy to tie it into GitHub or Git repositories."
"I still remember it was a struggle when we configured the initial network setup, that part was a little bit confusing about how exactly it works, we have two different Nutanix technicians who were on-site to help on the configuration. But both of them could not get right the first time, and we had to reset and start over again on both systems."
"NCM's analytics could be better because we're not getting an accurate analysis of our virtual machines, and we're over-provisioning some of them."
"The machine learning can be improved. There are a lot of false positives at times."
"Template management also needs improvement in OpenNebula because it's inferior right now."
"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."
"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."
"They should add more features like object storage."
"The front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."
"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."
"The storage feature that they have is a bit confusing."
"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."
 

Pricing and Cost Advice

"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."
"In my opinion, the pricing is reasonable."
"The solution is a bit high in price for what we are receiving as features. I feel they are overcharging us at approximately 25 percent. That is something that they should change."
"The pricing was very good. We were very pleased with what we were offered by our account manager. Because of that, we expanded Nutanix Cloud Manager, and we hope to expand even more. Right now, we are in Azure, and as we build up more and more within the NCM platform, we hope to expand into AWS as well."
"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."
"Its price is correct."
"Its cost is reasonable. The features are very good."
"The solution's price is reasonable."
"VRA is very expensive but OpenNebula is free."
"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."
"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."
