Featured Reviews

RituparnaBhattacharya - PeerSpot reviewer
Secret storage and certificate management have been streamlined
I am not on the developer's end. I am primarily the main infrastructure person. I'm not sure what needs improvement. Sometimes, we face issues that the support team is not aware of, necessitating investigation from their end. For example, one of our certificates was not getting deployed, and during that time, the support team was unsure and had to connect with the back-end team for assistance. Improvements can be made in this area, however, it's understandable that not everything can be perfect.
Gabor Nyerd - PeerSpot reviewer
Includes four services and four products, which can help organizations a lot
We found that sometimes integrations work, but testing them can take some time. Sometimes, configurations take much longer than expected. We have a configuration in place that needs to be synchronized with another server. However, the servers are four hours apart, so this can cause delays. In general, I believe that the time it takes to configure and test a service should be shorter. Sometimes, it can take a couple of hours to test a single configuration setting. Other times, it is only ten or fifteen minutes, which is normal. However, sometimes, even immediate actions can be triggered by configuration changes, and some settings can take up to eight hours to complete. I believe that this time can be improved. Microsoft is making a lot of improvements to its services in a short period of time. This is a good thing, as it means that the services are constantly being updated and improved. However, it can be challenging for customers to keep up with the changes. For example, a customer may read about an update, understand it, and share it with their colleagues and boss. However, it may take days or weeks to test the update and get the necessary approvals. This can be especially challenging for large customers with many users or machines. In some cases, Microsoft may change a service before the customer has had a chance to implement the previous update. This can be frustrating for customers, as it means that they have to constantly learn new things and adjust their workflows. On the one hand, it is important for Microsoft to keep updating and improving its services. This helps to ensure that the services are meeting the customers' needs and that they are staying ahead of the competition. Microsoft should also be mindful of the challenges that these changes can create for customers. One way to address this challenge is to provide customers with more time to implement changes. Microsoft could also provide more information about upcoming changes so that customers can plan ahead. Ultimately, Microsoft needs to strike a balance between keeping its services up-to-date and providing customers with a smooth transition to new features.
