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

"It has a user-friendly dashboard and interface."

"Single-click upgrades are the most valuable feature. In the sector in which we work, it is tough to have downtime and arrange firmware upgrades."

"Being able to upgrade our entire cluster with the click of a button during business hours with zero downtime has made managing our infrastructure so easy."

"The virtualization environment is now much easier to manage and maintain, there is only one vendor to call in case of issues and one single console to manage everything."

"The configuration is easy, and it's flexible."

"The hyperconvergence service, as well as the DR solution, are game-changers for Nutanix."

"Nutanix has the best virtual desktop infrastructure."

"Their Google operating system is more mature, so their results are much better."

More Nutanix Cloud Infrastructure (NCI) pros

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

"It created a reusable library with OpenStack features."

"The most valuable feature is the customization. With the customization you can really give the customers what they want."

"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."

"The documentation was plentiful and very helpful."

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

"The initial setup isn't too difficult."

"The solution is stable."

More Rackspace OpenStack pros

Cons

"Nutanix could streamline Acropolis' advanced management to keep pace with its competitors. For example, in VMware vSphere ESXi Hypervisor, you can directly put a host into maintenance mode via the GUI. However, it takes several steps to do this with Nutanix Acropolis, and you need to use the command-line interface for most of the steps."

"The initial setup can be a bit difficult."

"The pricing model for software and hardware subscription renewals can be improved."

"They could improve the graphical user interface."

"I would like better integration of XenServer into the AOS and Prism Central."

"I would like to see more Kubernetes and container-related workflows and multiple cloud-partner management. I would also like to see how they will synergize all these AI/ML functionalities that are available on other platforms."

"The self-service side of the product needs to be improved. We should be able to add two-factor authentication and more security layers to it."

"Deployment could be more user-friendly - currently, it requires certain skills with the network and nodes."

More Nutanix Cloud Infrastructure (NCI) cons

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

"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."

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

"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."

"The line migration is a problem."

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

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

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

More Rackspace OpenStack cons

Pricing and Cost Advice

"Its licensing is fine. They provide the flexibility to choose from different options. You can go with the standard plan. You can go with the pro or platinum plan. Generally, our clients go with the pro licenses, but if you go for the platinum license, you get even more capabilities. Their starter license is also quite good."

"NCI is quite expensive compared to other products. It would help us if Nutanix considered affordability when releasing new products. We have an annual license and are considering extending it for another year."

"The overall cost depends on the contract of each customer and the discounts they have, but the price for the three-tier architecture can be slightly lower."

"I know Nutanix and VxRail have similar prices and licenses. Nutanix is a go-ahead if AHV is used as hypervisor because it is already embedded in the price."

"Licensing depends on the features needed."

"Its price is fine. I can't really complain about that."

"This product is expensive, but they do have discounts. At one point, I saw that they were giving a 70% or 80% discount, which is a good thing, but maybe they should have a more realistic price and then a 5% to 10% discount."

"The basic license that comes with the box allows basic virtualization features but advanced automation features would require an upgrade of licenses."

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

"The pricing is low."
