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.

Managed containers have simplified on‑prem workloads and have enabled flexible virtualization
Innovation means that the user interface should be more familiar to users, and from my side, I see that some user interfaces are complex compared to other virtualization and containerization products, mostly for the virtualization. For the optimization level, I mainly expect a good user experience from Rackspace OpenStack's dashboard for resource optimization, where the design and functionality have to be very easy for the user to manage those solutions via their console dashboards. In my opinion, the main improvements for Rackspace OpenStack can focus on certain gaps available in the primary disaster recovery solutions, which should be developed for a specific customer requirement level like RPO, RTO, and things of that nature. Currently, most of the time, they are focusing on active-active solutions, but some customers are expecting active-passive solutions as well, so they have to focus on those kinds of areas for some customer requirements. 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. I would like to see additional features in the future such as replication technologies, networking, more advanced networking functionalities, and improved user dashboards.

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."
"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."
"There are many services that can be directly used which are not available in VMware."
"It created a reusable library with OpenStack features."
"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."
"Administrators are very comfortable with the functionality and services OpenStack offers."
"The open-source nature of OpenStack provides significant value."
"The most valuable feature is the customization, and with the customization you can really give the customers what they want."
"The solution is stable."
 

Cons

"The management is really difficult when it comes to systems with traditional services."
"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."
"The pricing of Rackspace is quite high in the Vietnam market."
"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."
"OpenStack is difficult for the novice in terms of beginning to use cloud tools."
"The line migration is a problem."
"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."
