Raouf Mahfoud Silhadi

Spécialiste VMware at a computer software company with 51-200 employees

Managing diverse environments has been streamlined with robust disaster recovery features and automation capabilities

The most valuable features I have found with Nutanix Cloud Manager (NCM) are related to Disaster Recovery, specifically the Nutanix Disaster Recovery solution with Prism Central, and Flow micro-segmentation. Flow micro-segmentation is part of the Nutanix Cloud Manager (NCM) networking capabilities, and most scenarios are related to standard clusters with Disaster Recovery, including environments with both Nutanix AHV and VMware. The importance of faster outcomes for their environment is significant; for example, when I delivered the Disaster Recovery solution, we included automation for auto-configuration of VMs and resizing of VMs, which replaced many tasks that were previously done manually. The implementation of automation solutions helps free up time for their IT team, allowing them to manage more of the application part rather than the infrastructure, especially for stability and automation tasks from Nutanix.

FOURES Jean-Philippe

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

"What I found most valuable in Nutanix Cloud Manager (NCM) is the one-click upgrade and the analytics it can provide for hyper-converged infrastructure."

"It is a stable solution."

"The most valuable feature is definitely the disaster recovery portion, which they call Xi Leap. It's included in the licensing. Before, we were on a solution that charged extra for DR software. And with Prism Pro, not only can we manage all of our other infrastructure in addition to our DR, in the same console, but we can set up recovery points. We can also set up scripts to run, so it gives us everything we need to have a solid DR plan in place."

"The solution's support for scripts... has reduced the man-hours it takes to deploy and support applications because we don't have to rewrite all the scripts."

"I like the analytics and the interface. Nutanix is easy to deploy and manage."

"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."

"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."

"The scripting, where you can use libraries, is a valuable feature. We don't really make the blueprints, as we have a third-party company that makes them for us. But it enables calling APIs in the blueprints. When we create a machine, we use IPAM from Infoblox and we can get an IP address. It's one platform to script and we can then use all the APIs to complete the scripts. It gives us a central management tool from which we can do a lot of things automatically."

More Nutanix Cloud Manager (NCM) pros

"With a single click, we could set things up and initiate them."

"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."

"The solution provides templates for configurations that can easily be exchanged to VMs."

"It's easy to integrate OpenNebula with our IT systems."

"The most valuable feature of OpenNebula is that it scales very well."

"The ability to use it almost like a public cloud for an organization is a big asset, as it will create a value proposition and can control costs in a great way."

"It makes maintenance very easy and stress-free for our teams."

"The live migration feature has been great and is something we use very often."

More OpenNebula pros

Cons

"It is important to mention that while Nutanix claims improvements in licensing over the past couple of years, I find it a bit annoying, as it still does not work as intended."

"There are some cases when there are multiple alerts for the same issue. For example, if I forget to put it in hosting maintenance mode, then I start getting multiple, duplicate alerts for the same host, which we don't want. If I have already received an alert, I don't want another alert. So, there are sometimes false positive alerts because of update activity where we forgot to put it in maintenance mode, then we get multiple alerts or emails."

"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."

"There should be more APIs to integrate with different vendors and to integrate with the existing solutions that we use on-prem."

"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."

"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."

"The biggest issue we've run into is not being able to quickly share information. More sharing features outside of just the standard reporting, where I can export something to a PDF, would be more helpful."

"I consider it a very complete platform, for now, I believe it is very good. It could be advanced and more updated over time. I would like to see updates like the creation of basic applications for monitoring through tables, telephones, external updates, sending manuals, or informational brochures by mail to go hand in hand with the platform and its updates."

More Nutanix Cloud Manager (NCM) cons

"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."

"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."

"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."

"Hosting platforms are limited so the deployment process needs improvement."

"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."

"There are no payment gateways in OpenNebula."

"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."

"The protocol for clusterization is rough and doesn't work well."

More OpenNebula cons

Pricing and Cost Advice

"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."

"I was not involved in purchasing Nutanix Cloud Manager (NCM), so I have no information on its pricing or cost. I do feel that it's fair that Nutanix Cloud Manager (NCM) is a product sold as one but with multiple tiers, though you need to make sure it isn't oversold in terms of client needs."

"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."

"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."

"Nutanix has good central management tools where one guy can manage the entire system. Looking at other systems, I need a guy to manage the servers and another guy to manage the cell network and storage. I need a bigger team for other solutions compared to Nutanix where I can use a small team and reduce my operations to manage the cluster. Sometimes what you hear with this solution is, "It is so expensive," but the cost and benefits that Nutanix has inside are really good."

"The pricing has been reasonable."

"Nutanix Cloud Manager (NCM) is cheaper than VMware and other products."

"Compared to UCS and the NetApp storage, Nutanix is actually cheaper."

More Nutanix Cloud Manager (NCM) pricing and cost advice

"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."

"We use the Community Edition, rather than the Enterprise Edition."

"The solution is open source so is free."

"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."

"OpenNebula gives good value for money."
