MuhammadAzhar Khan - PeerSpot reviewer
Auto-scaling capabilities enhance file management while reducing downtime
The most valuable feature of Amazon EFS is its auto-scaling capability. It's really easy to configure EFS by just creating it and running a command to directly configure it with my servers. It supports unlimited use, and charges are applied based on the file usage at the end of the month. The solution offers reduced downtime and increased durability through its auto-scaling features.
Karthik-A - PeerSpot reviewer
Has simplified customer data management and improved file transfer workflows
We are using AWS as well, and the main difference is that Microsoft Azure File Storage is more user-friendly for configuration-related and admin-related activities. We do not have to perform many complex activities, making it simpler compared to AWS. Security-wise, there are some concerns because it is in the cloud. The customers need to double-check, and they are not giving complete approval when it comes to security. I would rate Microsoft Azure File Storage's security compliance features seven or eight out of ten. It is secure, but since it is in the cloud, we have to convince customers when providing solutions. Many questions were raised while providing the architecture and solution for this file transfer management system. We convinced them because we have the feature and showed a demo, but it is still a prototype. We have to get approval before starting the work. The data redundancy options in Microsoft Azure File Storage are good. I am facing some challenges in convincing customers, and additional information would be helpful to address these challenges. Microsoft Azure File Storage saves time compared to AWS. We tried the prototype in AWS as well, but Azure is easier. Regarding cost, it is slightly less compared to AWS. The functionality of Microsoft Azure File Storage does not pose any issues, though basic users find it complex and require training. Regarding stability, I would rate Microsoft Azure File Storage 8.5 to 9. Scalability in Microsoft Azure File Storage is impressive. We recently handled a huge transaction during an iPhone launch without any problems.
