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 scalability is great."

"It's the only solution that can scale properly — there is no limitation on the number of nodes that a customer can have in the same cluster."

"If you are looking for a computer, power, networking and storage solution, this is a great option."

"In general, being able to patch and not having to pay for SanDisk is the best thing about hyper-converged."

"The solution is very stable. We haven't had any issues."

"My advice to anyone considering Nutanix Acropolis AOS is that you won't go wrong."

"The most valuable features of Nutanix Acropolis AOS are ease of management, hyper-convergence platform, and it has robust operations."

"Nutanix has the best virtual desktop infrastructure."

More Nutanix Cloud Infrastructure (NCI) pros

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

"The solution is stable."

"Rackspace OpenStack positively impacts my organization by making processes easier since I do not need to manage all servers manually because it efficiently manages server operations and maintains proper data, which saves time."

"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."

"OpenStack allowed for mass uploading of images to Akamai cloud services."

"Rackspace OpenStack is stable and reliable, often compared favorably against other solutions."

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

More Rackspace OpenStack pros

Cons

"The patch updates of Nutanix Acropolis could be improved."

"Reduce its power consumption."

"Given all the amazing features, there is room for improvement around the support ability of different hypervisors."

"The file services that they also provide need some more features, like on the Windows file server."

"Extra features should not be so expensive. We would love to be able to use or even just try some of the extra features without having to buy them."

"The product could be improved with more security. The product needs a bit more experience in the market. I think you don't have the possibility to add other hardware. It could be improved with the ability to add and extend."

"It is small but complex."

"In the next release, I would like better and more competitive pricing."

More Nutanix Cloud Infrastructure (NCI) cons

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

"The deployment process could be easy."

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

"In terms of what needs to be improved, I would say the support. Rackspace might have some good support but the open source OpenStack doesn't have support because there are too many versions coming and too many people are customizing it."

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

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

More Rackspace OpenStack cons

Pricing and Cost Advice

"The license is quite clear to me. It's much clearer than what we had with our previous virtualization environment. The licensing is not complex to understand."

"Nutanix price is high because it bundles all the components into single deals rather than allowing you to select the features that you want/will use."

"They offer multiple tier licensing which means that lower level licensing will have less features."

"Pricing varies greatly between license and editions."

"It is not cheap, but if you look at the return on investment and the total cost of ownership, it is worth the price."

"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 Acropolis AOS is affordable, it has good value. The final price depends a lot on the hardware used, it's an appliance in the end. Whether you use HPE as the hardware vendor or Supermicro as the hardware vendor, it really depends on what hardware is used which is the main cost."

"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."

More Nutanix Cloud Infrastructure (NCI) pricing and cost advice

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

"The pricing is low."
