The administrative side is suitable for technical people, but our finance and HR super users find it less user-friendly, as they prefer drag-and-drop features to build their own solutions without contacting IT.

There is still room for improvement in terms of pricing.
Director at Apeiros Solutions
AWS services typically offer more flexibility to end users.
Associate Director at LTI - Larsen & Toubro Infotech
In Autonomous, for example, where I think an autonomous database should manage storage correctly on its own, my experience is that often we have many allocated storage spaces that are free, but it is impossible to reclaim.

If Microsoft gives a report, such as a server performance report in a detailed way, which shows what is consuming more CPU, memory, and disk IO, and network utilization during a particular time, it would be helpful to visualize that information.

Featured Reviews

Syed Abid  - PeerSpot reviewer
Snr. Infrastructure Architect (Data Centre) at LogicEra
Versatile integrations and reliable customer satisfaction elevate cloud service experience
For Microsoft Azure improvement, they need to enhance their support system. The first level of support should be improved in terms of quality and response time. They need more technical support at the first level, as there are currently only one or two technical people among five to ten staff members at this level. They should ensure that the first level support is more technical because we normally provide services to technical users ourselves. When an issue arises, it usually escalates to the second or third level. When facing first level support, they may have limited knowledge and only collect screenshots to forward to their seniors. They should ensure that the first level support is aligned with L2 and L3 to better assist us, especially since we mention in the ticket that our issues are related to specific problems and require that sort of support.
Labhesh Hase - PeerSpot reviewer
Associate Director at LTI - Larsen & Toubro Infotech
Cost-effectiveness and pricing consistency support diverse high-intensity applications
The services of Oracle Cloud Infrastructure (OCI) are quite competent when compared to AWS Cloud, and they are also lower in cost. We use compute, storage, and network services. A notable feature is Oracle Cloud Infrastructure's consistent global pricing, which is advantageous. Furthermore, applications using Oracle Database not only work seamlessly on Oracle Cloud Infrastructure (OCI) but also benefit from a 25% offset on Oracle Database licenses.
