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.
