Infrastructure efficiency has improved significantly with quick server provisioning, though physical to virtual migrations need a streamlined in-house tool

From my experience with Nutanix Cloud Infrastructure (NCI), there is one area that needs improvement. When moving a critical infrastructure from a physical machine to Nutanix Cloud Infrastructure (NCI), we currently have to use a third-party tool to convert the physical machine to a VM. We have to use VMware converter to perform this conversion before moving it to Nutanix Cloud Infrastructure (NCI). I would suggest that Nutanix Cloud Infrastructure (NCI) should develop their own P2V (physical to VM) tools instead of requiring users to rely on third-party solutions.

Quotes from Members

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

Pros

"The technology of Nutanix Acropolis AOS is the most valuable feature. You don't need multiple screens to manage."

"Some of the most valuable features of Nutanix Acropolis are that it's free from Nutanix and it's very stable."

"Nutanix Acropolis AOS is easy to use, it is a great platform."

"One of the most valuable features of Nutanix is that it's easy to use. I love this solution—it's easy to maintain and update, and I think it's almost perfect."

"Its low maintenance is a key feature. It is easy to install, upgrade, and scale by adding more blocks."

"The Nutanix customer service is outstanding and easily the best from all vendors we work with."

"Nutanix Acropolis AOS is easy to use, integrates with other hardware configurations, and is simple to manage."

"Karbon is a must-have as it drastically simplifies the deployment of Kubernetes."

More Nutanix Cloud Infrastructure (NCI) pros

"The documentation was plentiful and very helpful."

"Apart from the main features, I really appreciate OpenStack's microservices architecture and its flexibility for deployment with different tools."

"The open-source nature of OpenStack provides significant value."

"I like its integration with GitLab and its simplicity. OpenStack has a lot of third-party libraries that it uses."

"There are many services that can be directly used which are not available in VMware."

"Administrators are very comfortable with the functionality and services OpenStack offers."

"The initial setup isn't too difficult."

"It was a very flexible and scalable solution. It was very useful because we were not dependent on a single vendor's solution. Increasing the number of machines or changing the hardware configuration was very easy."

More Rackspace OpenStack pros

Cons

"When we have issues with the solution, they tend to be around networking."

"The one note of improvement I have for Nutanix is that the installation should be easier."

"Nutanix Cloud Infrastructure (NCI) has really become very expensive."

"Storage utilization and optimization should be better."

"The only problem is that not many operating systems are supported on the AOS hypervisor. They need to probably increase the support on multiple operating systems. As of now, a very limited number of operating systems and patch levels are supported on AOS."

"It would be ideal if it was more secure."

"It is small but complex."

"There is a lot of functionality in Prism Central, but sometimes you want to see those features in Prism Element."

More Nutanix Cloud Infrastructure (NCI) cons

"So for the main stability, there have been a couple of issues that I've experienced."

"It should have a single dashboard for cloud management and on-premises systems"

"VMware has a side-to-side replication feature, which is still more mature than Rackspace OpenStack's which can't be used in a production environment."

"It could use more examples in different languages (API use cases)."

"The line migration is a problem."

"OpenStack is difficult for the novice in terms of beginning to use cloud tools."

"The pricing of Rackspace is quite high in the Vietnam market."

"OpenStack's UI, while user-friendly, could be improved to offer a more intuitive experience."

More Rackspace OpenStack cons

Pricing and Cost Advice

"Many of my customers have issues with Acropolis' licensing model because they are charging the customers based on two things— the CPUs and the capacity in the solid stack disk — and that's a problem. Nutanix's competitors are not licensing that layer, so this is something that they should change. They should abandon this licensing model because it's too complex. Technical support is bundled with the subscription."

"It is slightly more expensive compared to a standard, on-prem, bare-metal configuration. There is about a 30 percent overhead there."

"The solution could be a little less expensive."

"Its licensing model is easy, but the bad thing is that we need to pay for the whole capacity at once. With VMware vSAN, we only have to pay for the capacity that we are using, which is not the case with Nutanix. So, we have more overhead for the licensing cost with Nutanix."

"Nutanix Cloud Infrastructure's pricing is higher now."

"It's a cost-effective solution"

"When compared to the competitors, the price is reasonable."

"Nutanix Cloud Infrastructure is expensive."

More Nutanix Cloud Infrastructure (NCI) pricing and cost advice

"I use it as an open-source tool."

"The pricing is low."
