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

"In six years, I can recall just a couple instances, three in total, where we've experienced outages due to hardware or firmware issues during upgrades, but none of these incidents noticeably affected us."
"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 most important aspect of Nutanix Cloud Manager (NCM) is that it helps us manage the infrastructure as a hyperconverged infrastructure in HCI mode."
"We haven't faced any problems because Nutanix provides an outside team. We haven't had any issues requiring L3 support, and the L1 and L2 engineers are on-site."
"It is a scalable solution."
"The customer service and technical support I've received have been phenomenal."
"I am quite happy with the outcomes we have received using Nutanix Cloud Manager (NCM) so far."
"Most customers are transferring to Nutanix infrastructure because it is scalable, reliable, and performance-focused."
"It makes maintenance very easy and stress-free for our teams."
"With a single click, we could set things up and initiate them."
"It's easy to integrate OpenNebula with our IT systems."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"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."
"OpenNebula is lightweight, stable, and easy to customize."
"The service feature appeals most to us, thus it is the most valuable."
"It is quite easy to deploy."
 

Cons

"The solution's virtualization could be even better."
"I've had some challenges with the latest versions. I think the resource requirements are a little too high. The resources that Cloud Manager needs begin to account for a larger proportion of the resources the customers buy. In the announcement for the version they released today, they said there would be a lightweight version, so hopefully that has been addressed."
"We have had our fair share of issues while upgrading early on, but the process now is working flawlessly."
"The integration with Splunk is a little lacking, and this is something that we've worked on with Nutanix quite extensively in the last year or two. It didn't really have a good integration. They built some dashboards, where they were trying to kind of recreate Prism. Prism is its own utility; it works well for what it does. But it doesn't provide us quite the detail that we are looking for or the historical data that we were after. So we had to build our own custom apps for Splunk."
"Recently, I have had quite a few issues with Nutanix Guest Tools (NGT). When you do a full update from LCM, your NGT doesn't automatically install on your VMs. You need to go back to Prism Central and select a list of VMs, then install NGT. You need to go to each of those VMs, then restart them to get the NGT installed. Also, there are some VMs that we have on our system that we used to run on an old environment, which was Hyper-V. Previously, we had VMware, so some of our VMs are Windows 7 32-bit and Windows 7 64-bit. However, the NGT no longer allows for installations on those."
"In the gambling industry, you have a lot of regulation from different countries. One of those regulations states that you have to be able to send all the logs of your Prism to a separate server, what we call the syslog server. On Prism Central, this doesn't work. We have opened a case for it, since this is a basic feature nowadays. We spoke to Nutanix, and they said that it will be in future updates. We did an update, following their support, but once we did the update, it wasn't fixed."
"Its licensing can be better."
"We would like to be able to provision virtual machines at the computing level, as that would give us an added value against the competition."
"The storage feature that they have is a bit confusing."
"The UI, monitoring, and alerting could benefit from further improvements."
"The front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."
"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."
"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."
"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."
"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."
 

Pricing and Cost Advice

"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."
"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."
"The product is expensive...When I have to sell the tool to a customer, I would say that it is not very expensive and can be termed priceless."
"Compared to UCS and the NetApp storage, Nutanix is actually cheaper."
"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."
"I think it can be more cost-effective."
"The solution’s pricing is not outrageous like other products."
"The company frequently changes its prices, and it is not clear how the subscription-based model works."
"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 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."
"The solution is open source so is free."
"VRA is very expensive but OpenNebula is free."
"OpenNebula gives good value for money."
"We use the Community Edition, rather than the Enterprise Edition."
