Has supported seamless microservices deployment and improved cost control through managed infrastructure
Microsoft Azure Container Service includes being a very mature tool and a fully managed service, making it ready to use. You can simply opt for it and use it. As a managed service, you don't need to take care of the managed components. You only need to take care of whatever user-space you are managing. All the managed components are taken care of by Microsoft. They provide support for different upgrade operations, and anything related to managed components such as the controller nodes, those things they can take care of automatically. This is actually a very challenging task that is handled by Microsoft itself. Microsoft Azure Container Service has positively impacted my organization as it is a very mature tool and, when using the Azure platform, it's highly secure. It can offer end-to-end encryption and take care of all kinds of compliance. It also offers Azure Defender for Cloud that can provide security recommendations on a daily basis, making it a very mature product.

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.
