PureSystems, something old, something new, something from big blue
PART I For a certain generation of IBM faithful or followers the recently announced PureFlex and PureApplication systems might give a sense of DejaVu perhaps even causing some to wonder if they just woke up from a long Rip Van Winkle type nap. Yet for another generation who may not yet be future…

Quotes from Members

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

Pros

"The strengths of the system is how the Flex scales from a very powerful, next generation BladeCenter all the way up to an IaaS platform."
"Rackspace OpenStack is stable and reliable, often compared favorably against other solutions."
"The open-source nature of OpenStack provides significant value."
"Customer Service: Top. Technical Support: Top"
"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."
"Apart from the main features, I really appreciate OpenStack's microservices architecture and its flexibility for deployment with different tools."
"The most valuable feature is the customization, and with the customization you can really give the customers what they want."
"OpenStack allowed for mass uploading of images to Akamai cloud services."
"The documentation was plentiful and very helpful.​"
 

Cons

"The FSM does not quite deliver in the areas it plays too. A fairly sluggish interface that is more complex and less streamlined than it perhaps could be, holds it back and deployment of certain functionality from the switches requires more user intervention than feels necessary."
"OpenStack is difficult for the novice in terms of beginning to use cloud tools."
"The deployment process could be easy."
"As a beginner, I find some difficulties in understanding Rackspace OpenStack, as it can be complex without a foundational grasp of cloud and networking concepts."
"So for the main stability, there have been a couple of issues that I've experienced."
"It should have a single dashboard for cloud management and on-premises systems"
"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."
"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."
