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.

Cloud storage and email have supported our association but usability and search still need work
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. I didn't really feel there was anywhere I could go if I had questions in order to live chat or reach out to someone; if that exists, it wasn't made apparent to me. Being able to search keywords and having what you're looking for come up, whether it's an email or in the drive, could definitely be improved, and making it work better with cell phones and improving the setup to be more user-friendly would be helpful.

Quotes from Members

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

Pros

"We never have any issues or glitches."
"I am very impressed by the stability of the program."
"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."
"OpenStack allowed for mass uploading of images to Akamai cloud services."
"Rackspace OpenStack is stable and reliable, often compared favorably against other solutions."
"Apart from the main features, I really appreciate OpenStack's microservices architecture and its flexibility for deployment with different tools."
"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 initial setup isn't too difficult."
"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 open-source nature of OpenStack provides significant value."
 

Cons

"The management is really difficult when it comes to systems with traditional services."
"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."
"OpenStack is difficult for the novice in terms of beginning to use cloud tools."
"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."
"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."
"OpenStack's UI, while user-friendly, could be improved to offer a more intuitive experience."
"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."
"The pricing of Rackspace is quite high in the Vietnam market."
