Enhanced data security with seamless integration and static website capabilities
S3 is a great service offering numerous possibilities. It allows for storing objects and files of various types. I appreciate its capability to create static websites and integrate with services like CloudFront, EC2, and DynamoDB. Despite being focused on security, I leverage features such as cryptography and integration with CloudTrail.
PrateekMehrotra - PeerSpot reviewer
Comprehensive cloud data management with seamless scalability and robust security features
One valuable feature of Microsoft Azure Object Storage is that it provides REST API access to your data, allowing easy data consumption. Additionally, it offers encryption for data at rest and in transit as a standard feature, which enhances security. Another key feature is out-of-box storage management, removing the need for us to manage storage capacity and maintenance. Scalability and data redundancy across zones and regions are also noteworthy.
