Phani Venkata Sai BKD - PeerSpot reviewer
Technology Lead at Thomson Reuters
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

"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."
"Nutanix has been a great company to work with."
"The blueprints and templates are very nice and easy to use. They are very valuable because we can configure the entirety of an environment as a template and reuse it multiple times."
"It offers high availability and consistency."
"The most valuable features are the compliance features and the chargebacks."
"I also like the fact that the solution manages itself. It has one interface where you can basically see all your servers. So, you can manage your servers and see whether you are falling short on space or disc usage. Also, in case your RAM is only using four Gigabytes of memory instead of eight, you can extend out the over-provisioned mail and save your cluster for four Giga of RAM."
"The ability to cross between different clouds is a valuable feature of Nutanix Cloud Manager Intelligent Operations."
"Among the most valuable features are the one-click upgrade, that Nutanix is very easy to understand, and that it's very user-friendly."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"The most valuable feature of OpenNebula is that it scales very well."
"OpenNebula freed my customer from doing the maintenance operations of the servers because now that can be done by his clients."
"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."
"It's easy to integrate OpenNebula with our IT systems."
"For our use case, we found the solution to be the best fit when dealing with infrastructure services."
"The service feature appeals most to us, thus it is the most valuable."
"The live migration feature has been great and is something we use very often."
 

Cons

"If they integrated more with GPT, that would be ideal."
"Better AI would be a feature I would want to see in the next update."
"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."
"There are some load-balancing features that are currently missing in the flow network security and could potentially be added in the future."
"The areas that could be improved include the Nutanix Move tool, which is presently used for migrating VMs from one setup to a private cloud. It can be improved by adding some other setups, such as Citrix Xen, Red Hat Virtualization, and Red Hat OpenShift. There are many other cloud products that need to be added to the Nutanix Move tool, which would be really helpful for us in India, where we use different setups such as Red Hat Virtualization, OpenShift, Citrix XenCenter, Hyper-V, and VMware."
"I would rate NCM's stability at five out of 10."
"In some ways, Nutanix Cloud Manager abstracts out certain items in a simplified manner, which makes it good for training. At other times, to get to the next technical level, we want to actually dive in, and Nutanix Cloud Manager sometimes restricts us from actually diving into the deeper technical pieces. There's no advance button that lets us do more advanced things without having to drop out to the CLI to do the command line piece."
"In our company, even though not directly in Nutanix Cloud Manager (NCM), we saw that tool has many layers in it. An integration between Nutanix Cloud Manager (NCM) and Nutanix Kubernetes Platform would be a great deal."
"The UI, monitoring, and alerting could benefit from further improvements."
"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."
"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 protocol for clusterization is rough and doesn't work well."
"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."
"Template management also needs improvement in OpenNebula because it's inferior right now."
"The front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."
"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."
 

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."
"Its acquisition and support cost is nominal. It is not too high, and it is not too low. It is within the budget, and there are no issues on that part."
"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 solution’s pricing is not outrageous like other products."
"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."
"While the product may seem to be more expensive at first, it ultimately pays for itself within a short time frame due to the hours saved on maintenance."
"The solution is expensive."
"On a scale from one to ten, if one is a low price and ten is a high price, I rate the solution's pricing a six."
"The solution is open source so is free."
"We use the Community Edition, rather than the Enterprise Edition."
"OpenNebula gives good value for money."
"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."
"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."
