Amazon Simple Storage Service (Amazon S3), provides developers and IT teams with secure, durable, highly-scalable object storage. Amazon S3 is easy to use, with a simple web services interface to store and retrieve any amount of data from anywhere on the web. With Amazon S3, you pay only for the storage you actually use. There is no minimum fee and no setup cost.
Amazon S3 provides a highly durable storage infrastructure designed for mission-critical and primary data storage. Amazon S3 redundantly stores data in multiple facilities and on multiple devices within each facility.
To increase durability, Amazon S3 synchronously stores your data across multiple facilities before confirming that the data has been successfully stored. In addition, Amazon S3 calculates checksums on all network traffic to detect corruption of data packets when storing or retrieving data. Unlike traditional systems, which can require laborious data verification and manual repair, Amazon S3 performs regular, systematic data integrity checks and is built to be automatically self-healing.
Amazon S3 provides additional security with Multi-Factor Authentication (MFA) Delete. When enabled, this feature requires the use of a multi-factor authentication device to delete objects stored in Amazon S3 to help protect previous versions of your objects.
By enabling MFA Delete on your Amazon S3 bucket, you can only change the versioning state of your bucket or permanently delete an object version when you provide two forms of authentication together:
Your AWS account credentials
The concatenation of a valid serial number, a space, and the six-digit code displayed on an approved authentication device
Amazon S3 enables you to utilize Amazon Glacier, an extremely low-cost storage service for data archival. Amazon Glacier stores data for as little as $0.01 per gigabyte per month, and is optimized for data that is infrequently accessed and for which retrieval times of 3 to 5 hours are suitable. Examples include digital media archives, financial and healthcare records, raw genomic sequence data, long-term database backups, and data that must be retained for regulatory compliance.
Amazon S3 makes it easy to manage your data. With Amazon S3’s data lifecycle management capabilities, you can automatically archive objects to the lower-cost Amazon Glacier storage or perform recurring deletions, enabling you to reduce your costs over an object’s lifetime. Amazon S3 also allows you to monitor and control your costs across your different business functions. All of these management capabilities can be easily administered using the Amazon S3 APIs or console. The various data management features offered by Amazon S3 are described in detail below.
The AWS Free Tier is designed to enable you to get hands-on experience with AWS at no charge for 12 months
AWS Import/Export accelerates moving large amounts of data into and out of AWS using portable storage devices for transport. AWS transfers your data directly onto and off of storage devices using Amazon’s high-speed internal network and bypassing the Internet. For significant data sets, AWS Import/Export is often faster than Internet transfer and more cost effective than upgrading your connectivity. You can use AWS Import/Export for migrating data into the cloud, distributing content to your customers, sending backups to AWS, and disaster recovery.
