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 In the latest versions, the Prism interface has been replaced by Prism Central.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

"Its most valuable feature is simplicity. It is so easy to use. Upgrades are easy. It is easy in terms of disaster recovery, failover, database provisioning, and reporting. Everything about it is just simple."

"Switching to Nutanix flipped the value proposition around, and suddenly one technical person qualified in Nutanix was all that was needed."

"Scaling is very easy and no limitations are set."

"Each performance test with SQL, Exchange, Oracle, or SAP is better than on a three-tier architecture."

"If you are looking for flexibility, space-saving, power-saving, and the best ROI, this is the solution to use."

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

"Short answer: Ease of use, fast deployment, linear scaling of performance with capacity and richness of product features."

"In the world of IT operations, there is a lot of noise. Traditionally, systems would generate a great deal of alerts, events, and notifications, often leading to the operator either a) not seeing critical alerts since they are lost in the noise or b) disregarding the alerts/events."

More Nutanix Cloud Infrastructure (NCI) pros

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

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

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

"In my experience, Rackspace OpenStack delivered a stable, flexible, and reliable private cloud environment."

"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."

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

"The most useful opinion about Rackspace OpenStack is that it is very flexible, first of all, and the most important feature is that it is feature-rich."

"The initial setup isn't too difficult."

More Rackspace OpenStack pros

Cons

"USB dongle-based licenses do not allow us to directly locate the USB ports on Nutanix."

"Nutanix Cloud Infrastructure can be improved in terms of the sizing of the solution."

"The product needs improvement in the areas of SAN attachment for high capacity and high I/O profile workloads."

"In the next release of this solution, they could improve by being more competitive with VMware. I would like all third-party solutions to work well with Nutanix Acropolis AOS."

"The software-defined networking should be improved. It is quite substandard as compared to the VMware variant. The software-defined networking is quite limited, and we usually use other products to do that. We're aware that Nutanix is working on that and will be coming out with better solutions, and we can't wait because to do a fully software-defined architecture, the abstraction layer needs not only software-defined storage, which you have, but also the software-defined networking piece."

"The biggest thing that I've seen has been the backup and recovery which has been challenging for them over the past couple of years."

"In Thailand, there really isn't a cloud version of Nutanx available to us."

"For these types of workloads, we realized the solution doesn’t seem to fit well, leaving many of the requests either being dropped or transmission lost."

More Nutanix Cloud Infrastructure (NCI) cons

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

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

"I cannot comment comprehensively on how Rackspace OpenStack can be improved, as I do not find that much difference; however, some areas can be improved, such as support for OEMs deploying highly specialized real-time telecom and media workloads."

"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."

"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."

"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."

"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."

More Rackspace OpenStack cons

Pricing and Cost Advice

"I would rate the price seven out of ten with ten being the most expensive."

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

"I think it's cheaper than VMware in terms of cost."

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

"There is a license required for this solution and my clients usually purchase a two-year license with extended support. The price of the solution could be reduced, it is more expensive than competitors."

"The initial cost is affordable but the renewal fees are high."

"We are aware of the pricing since we renew every year, at almost $100,000 per year."

"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."

More Nutanix Cloud Infrastructure (NCI) pricing and cost advice

"The pricing is low."

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