Program Manager at SirfinPA
A stable solution that can be deployed in parts to improve its robustness and reliability
Our clients are usually enterprise businesses. IBM Cloud Kubernetes Service is a good solution because our customer requires very rapid deployment, and the solution is critical for his business. If the system is down, the lawyer cannot send documents, and people may be in jail. Overall, I rate IBM Cloud Kubernetes Service an eight out of ten.
Bruna Müller - PeerSpot reviewer
License manager at a financial services firm with 10,001+ employees
Centralized asset data has transformed how we manage licenses and make cost-saving decisions
One problem that we faced using Spot by Flexera is that in certain servers, the data was not being updated correctly, and we had a certain delay. For example, someone was using a computer, and then this user received a new one. In Spot by Flexera, we could see both computers, the old and the new one, but the system was not recognizing that the old one was no longer being used. We had a couple of IT assets that were not being used, and we had this information in our internal servers, but Spot by Flexera was not able to update on time. We had to fix this information manually.
