Infrastructure Head at a program development consultancy with 11-50 employees
A very high IOPS that gives more I/O transactions per second
Scalability used to be an issue so at that time it was rated an eight out of ten. We have become OPEX-based and rent storage from them. Physical storage is about 200% of our requirements but we only pay for what we use. This resolved all of our scalability issues. When we reach a certain threshold like 100%, OPEX calls us and asks if we want to add more storage. Our total capacity right now is 300 terabytes but we are only using around 200 terabytes. We bought the storage two years ago and our projections are on par. We don't need more capacity now but have plans to increase in another two years. With our OPEX storage, scalability is rated a nine out of ten.

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

"The combination of Cisco's architecture and IBM's flash technology, where Cisco provides FI technology for one simple architecture and IBM's flash technology is fast, is valuable."
"Replication and DR implementation became faster."
"The solution has high IOPS and the I/O is important because it gives us more transactions per second."
"Rackspace OpenStack is stable and reliable, often compared favorably against other solutions."
"The documentation was plentiful and very helpful.​"
"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."
"Customer Service: Top. Technical Support: Top"
"The solution is stable."
"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."
"Apart from the main features, I really appreciate OpenStack's microservices architecture and its flexibility for deployment with different tools."
"The open-source nature of OpenStack provides significant value."
 

Cons

"Raw data mapping for storage should be a given option."
"The solution should improve deduplication to get a lot of savings."
"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."
"The deployment process could be easy."
"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."
"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."
"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."
"OpenStack is difficult for the novice in terms of beginning to use cloud tools."
"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."
"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."
 

Pricing and Cost Advice

"The solution is enterprise level so it is expensive."
"I use it as an open-source tool."
"The pricing is low."
