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."
"The open-source nature of OpenStack provides significant value."
"The solution is stable."
"Customer Service: Top. Technical Support: Top"
"There are many services that can be directly used which are not available in VMware."
"The most valuable feature is the customization, and with the customization you can really give the customers what they want."
"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."
"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."
 

Cons

"The management is really difficult when it comes to systems with traditional services."
"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."
"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."
"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 line migration is a problem."
"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."
"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."
