Easy to work on and has never had any glitches or issues
My advice to others would be the following: if you have a traditional application, like core banking, or transactional, or something that has to do with money, it is better to go with IBM. The reason I'm saying this is because it is more stable and easier to monitor. But if you are looking for the newest architecture of the application cloud, you should go with either hyper-converged or converged. I would like to see better management and high availability in the next release of this program. With classical architectural systems, it's more delicate and difficult to have a high availability of systems. But with hyper-converged systems, we can have it in the easiest way. On a scale from one to ten, I will rate this program an eight.

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

"I am very impressed by the stability of the program."
"We never have any issues or glitches."
"In my experience, Rackspace OpenStack delivered a stable, flexible, and reliable private cloud environment."
"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 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."
"Customer Service: Top. Technical Support: Top"
"The most valuable feature is the customization, and with the customization you can really give the customers what they want."
"Rackspace OpenStack impacted my organization positively in that the drive helped me keep files in an organized folder, and obviously we needed email addresses to be able to communicate with each other and for outsiders to be able to email us."
"The documentation was plentiful and very helpful.​"
"The initial setup isn't too difficult."
 

Cons

"The management is really difficult when it comes to systems with traditional services."
"It should have a single dashboard for cloud management and on-premises systems"
"It could use more examples in different languages (API use cases).​"
"We are moving from Rackspace OpenStack to CloudStack due to the requirement of human resources and technicality. There are lots of moving parts in Rackspace OpenStack."
"The deployment process could be easy."
"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."
"Rackspace OpenStack can be improved because it wasn't clear that you have to cancel 30 days before; otherwise they charge you for the month."
"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."
"OpenStack is difficult for the novice in terms of beginning to use cloud tools."
