What Is Amazon Simple Storage Service (Amazon S3)?
Amazon Simple Storage Service (Amazon S3) is a cloud storage assistance that makes it easy to store any amount of information, anytime, from anywhere on the web. It's durable, secure, highly scalable and cost-effective. It's durable because Amazon S3 combines replication and multiple facilities to ensure data is not lost during an outage. It authorizes you to focus on your core business instead of worrying about keeping your data safe. Amazon S3 is secure because all data stored in Amazon S3 is encrypted at rest and optionally transmitted over SSL (Secure Socket Layer). All accesses to objects are authorized through IAM policies and permissions. Your data is only accessible by you or those you grant permission to access. Amazon S3 is available whenever you need it—there's no need to schedule maintenance windows or make capacity planning a significant concern. Amazon S3 is secure—you can set permissions to control access to your data. It's inexpensive, reliable, and easy to use. Amazon S3 is designed for durability—Amazon S3 stores your data in replicated data centers, protecting it against natural disasters and other unexpected issues. For example, if a data center cannot operate because of a natural disaster, the service will automatically fail over to another data center.
