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 configuration is easy, and it's flexible."

"The initial setup was quite straightforward."

"One of the main features of the solution is that it works on many hypervisors. It is a big advantage. Additionally, the solution is compatible with VMware and Hyper-V, and the management interface, which is called Prism, is very intuitive and user-friendly."

"If you want to build a hybrid cloud, and have a good balance between cost and performance, then Nutanix is good option."

"Nutanix Acropolis AOS has very good stability."

"The solution is well integrated with other vendors."

"One of the most valuable features is how well this solution performs. It's stable, aside from some patch issues, but it's great from a virtualization and scalability perspective."

"Best features are around data locality, compression, and deduplication."

More Nutanix Cloud Infrastructure (NCI) pros

"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."

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

"The initial setup isn't too difficult."

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

"The documentation was plentiful and very helpful."

"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

"Some clients find the solution's cost to be too high."

"Lacks sufficient integration with other vendors and public clouds."

"If we can have certified compatibility with other companies, such as Oracle, then it would let us know that they function correctly together."

"It is a CentOS-based operating system, but CentOS releases security patches almost every week or every other week. However, Nutanix releases their upgrade at three or four month intervals. According to my organization's SLA, if a critical patch is released during that time, then I need to implement the patches within 30 days. If it is a standard patch, then I need to patch it within 60 days. Since that is my SLA, I cannot meet my SLA for security because Nutanix will not release the upgrade within these 30 days. Between the critical patch release and the Nutanix release, my customers say they are vulnerable and I am accepting the risk while the SLA is breached."

"They should support more VM, which is not currently supported."

"I think some of the tasks that must be done using CLI could be added to the web interface."

"The scalability of the solution had some issues because there were many VMs and the replication ran into some bottlenecks. It was an issue that was known to Nutanix and it was not disclosed to the customer."

"The process of migrating from old hardware to new could improve."

More Nutanix Cloud Infrastructure (NCI) cons

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

"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."

"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."

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

"The deployment process could be easy."

"The line migration is a problem."

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

More Rackspace OpenStack cons

Pricing and Cost Advice

"Nutanix Acropolis AOS price includes no additional costs for features."

"My advice is to get the ultimate license, as it is worth it."

"Cost-wise, it is very good. It is like the hypervisor cost is not there. We only need to pay for the system and AOS licenses."

"The solution is quite expensive."

"The price of the license for Nutanix Acropolis AOS is less expensive than the competition. There is a favorable cost saving. Having only the need to deal with a single vendor, the management of the customer's entire stack is cost-effective."

"Work close with your InfraTeam and discuss with Nutanix the best way to achieve sizing and price that are right for you."

"We got the renewal done recently, and there was no cost involved."

"Pricing for Nutanix Acropolis AOS is higher. This is one of the reasons why we were looking into other options."

More Nutanix Cloud Infrastructure (NCI) pricing and cost advice

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

"The pricing is low."
