Hyper-converged storage has improved performance and now supports high redundancy for our VMs

Nutanix Cloud Infrastructure (NCI) was transparent because we were on a regular infrastructure before. We went on NCI and were able to improve performance, but it did not really change how things worked. The performance was really better for applications and access times to the data. I regularly looked at the analytics to see what was going on in my servers and what it was saying to optimize performance. It was pretty interesting because it could analyze and give insights on how to get things working better. In the latest versions, the Prism interface has been replaced by Prism Central. This requires another machine to be deployed to manage the servers.

Private cloud control has deepened my DevOps automation and strengthened security practices

For improvement, I feel the documentation available for setting up and creating infrastructure using Rackspace OpenStack could be enhanced, as I personally find the existing documents are not sufficient for new learners or beginners. We can also work on improving the user interface; the Horizon dashboard is functional, but compared to AWS, Azure, or Google Cloud, the UI feels somewhat dated. A more modern, intuitive interface with better navigation would enhance the overall user experience, especially for new users. Improving the documentation, including more real-world deployment examples, troubleshooting guides, and architecture best practices, would make onboarding much easier. Faster upgrades would also help; Rackspace OpenStack upgrades can sometimes be complex, so simplifying the upgrade process and minimizing downtime would assist organizations in maintaining their environments more easily. Additionally, improving monitoring capabilities would be beneficial, with advanced monitoring and analytics dashboards providing administrators deeper visibility into performance, capacity, and potential issues without relying heavily on third-party tools. Adding more managed services, similar to what public cloud providers offer, could reduce operational overhead while still allowing customers to retain the flexibility of a private cloud. Lastly, integrating AI could be valuable, with AI-driven recommendations for capacity planning, security monitoring, and automated troubleshooting improving platform management.

Quotes from Members

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

Pros

"The technical support was great they were very helpful."

"The simplicity when it comes to building your own automation has been excellent."

"We increased stability and availability to 99.999%, and increased performance on our software platforms and databases drastically."

"The product provides a complete and wonderful package, and the best feature is the level of user-friendliness the solution offers, it's a class apart."

"The scalability, performance, and licensing model are the most valuable features."

"The level of statistical performance data that it can confirm in real-time is extremely useful. I can see what my VM’s hosts and guests are doing from a single pane of glass and identify issues before they would otherwise become apparent."

"What I like the most are the high-availability and scalability."

"Flexibility. We're able to mix performance nodes with storage nodes easily. Unlike other vendors where, if we start a hyperconverged solution with them, we have to stick to a specific model, to a specific series with specific capabilities, with Nutanix it's very easy to mix and match the best solution, especially for a dynamic infrastructure like ours."

More Nutanix Cloud Infrastructure (NCI) pros

"Rackspace OpenStack has positively impacted my organization by bringing us much closer to our customers based on the supportability this platform provides, and it has unique features which are very useful for our customers."

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

"The solution is stable."

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

"The initial setup isn't too difficult."

"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."

"Customer Service: Top. Technical Support: Top"

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

More Rackspace OpenStack pros

Cons

"Nutanix needs more development on DRC solutions embedded in Acropolis."

"As of now, Acropolis and VMware cannot talk to each other. Until we have some kind of interface, it would be much better for Nutanix if they built an interface that can talk. Otherwise, if I have a VMware stack and I already have a Nutanix stack, I can create containers, I create clusters on VMware, I create clusters on Nutanix."

"The technology has a lot of room for improvement. For example, when they want to segment applications in conjunction with NSX, which VMware uses, Acropolis is not compatible with the competitors. The integration in the security layer is not compatible with NSX for the application segmentation that uses VMware."

"We had a few problems with the foundation machine that you can use to build your systems out. We've got it working now, but it should be improved."

"The technical support is not great, but it's good."

"Pricing transparency: Software and hardware should be separate items."

"The access speed needs to be improved."

"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."

More Nutanix Cloud Infrastructure (NCI) cons

"For improvement, I feel the documentation available for setting up and creating infrastructure using Rackspace OpenStack could be enhanced, as I personally find the existing documents are not sufficient for new learners or beginners."

"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."

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

"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 for Rackspace OpenStack is sometimes not competitive according to other market products, as sometimes the price is high for some components like Advanced Cluster Management (ACM) and Advanced Cluster Security, which are very costly add-ons, not the main license."

"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."

More Rackspace OpenStack cons

Pricing and Cost Advice

"When we purchase a new physical server or a couple of physical servers into our cluster, we always purchase it with Nutanix licensing. We are receiving the license from Nutanix directly and not from the vendor. In the way we're dealing, with the licenses it is a bit costly for us but as the company is getting larger, day by day or year by year, those licensing costs become lower each time for us. We are purchasing the licenses for three years for some of our clusters and for some others for five-year licenses and the licenses are still costly. We have good discounts for the licenses, but it is still expensive."

"The one disadvantage is relative, financially Nutanix Acropolis AOS is a little bit more expensive than the old solution."

"If they could further reduce the cost, that would be great. I would like to see the cost be less than the equivalent three-tier architecture."

"The product’s licensing fee is moderately expensive."

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

"The solution is quite expensive."

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

"The licensing costs are a bit expensive but when you compare the features, it's reasonable."

"The pricing is low."

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