Amazon Simple Storage Service (Amazon S3) is object storage with a simple web service interface to store and retrieve any amount of data from anywhere on the web. It is designed to deliver 99.999999999% durability, and scale past trillions of objects worldwide.
Customers use S3 as primary storage for cloud-native applications; as a bulk repository, or "data lake," for analytics; as a target for backup & recovery and disaster recovery; and with serverless computing.
It's simple to move large volumes of data into or out of Amazon S3 with Amazon's cloud data migration options. Once data is stored in S3, it can be automatically tiered into lower cost, longer-term cloud storage classes like S3 Standard - Infrequent Access and Amazon Glacier for archiving.
Amazon S3 is simple to use with a web-based management console and mobile app. S3 also provides full REST APIs and SDKs for easy integration with third-party technologies.
Amazon S3 provides durable infrastructure to store important data and is designed for durability of 99.999999999% of objects. Your data is redundantly stored across multiple facilities and multiple devices in each facility.
With Amazon S3, you can store as much data as you want and access it when needed. You can stop guessing your future storage needs and scale up and down as required, dramatically increasing business agility.
Amazon S3 Standard is designed for up to 99.99% availability of objects over a given year and is backed by the Amazon S3 Service Level Agreement, ensuring that you can rely on it when needed. You can also choose an AWS region to optimize for latency, minimize costs, or address regulatory requirements.
Amazon S3 allows you to store large amounts of data at a very low cost. Using lifecycle policies, you can set policies to automatically migrate your data to S3 Standard - Infrequent Access and Amazon Glacier as it ages to further reduce costs.
Simple Data Transfer
Amazon provides multiple options for cloud data migration, and makes it simple and cost-effective for you to move large volumes of data into or out of Amazon S3. Customers can choose from network-optimized, physical disk-based, or third-party connector methods for import to or export from of S3.
Amazon S3 is deeply integrated with other AWS services to make it easier to build solutions that use a range of AWS services. Integrations include AWS Storage Gateway, Amazon CloudFront, Amazon CloudWatch, Amazon Kinesis, Amazon RDS, Amazon Glacier, Amazon EBS, Amazon DynamoDB, Amazon Redshift, Amazon Route 53, Amazon EMR, Amazon VPC, Amazon KMS, and AWS Lambda.
Easy to Manage
Amazon S3 Storage Management features allow you to take a data-driven approach to storage optimization, data security, and management efficiency. These enterprise-class capabilities give you data about your data, so you can manage your storage based on that personalized metadata.
Amazon S3 is an excellent choice for a large variety of use cases ranging from a simple storage repository for backup & recovery to primary storage for some of the most cutting edge cloud-native applications in the market today - and everything in between.
Backup & Archiving
Amazon S3 offers a highly durable, scalable, and secure destination for backing up and archiving your critical data. You can use S3’s versioning capability to provide even further protection for your stored data. You can also define lifecycle rules to automatically migrate less frequently accessed data to S3 Standard - IA and archive sets of objects to Amazon Glacier.
Content Storage & Distribution
Amazon S3 provides highly durable and available storage for a variety of content. It allows you to offload your entire storage infrastructure into the cloud, where you can take advantage of S3’s scalability and pay-as-you-go pricing to handle your growing storage needs. You can distribute your content directly from S3 or use S3 as an origin store for delivering content to your Amazon CloudFront edge locations.
Big Data Analytics
Whether you’re storing pharmaceutical or financial data, or multimedia files such as photos and videos, Amazon S3 can be used as your big data object store. Amazon Web Services offers a comprehensive portfolio of services to help you manage big data by reducing costs, scaling to meet demand, and increasing the speed of innovation.
Static Website Hosting
You can host your entire static website on Amazon S3 for a low-cost, highly available hosting solution that can scale automatically to meet traffic demands. With S3, you can reliably serve your traffic and handle unexpected peaks without worrying about scaling your infrastructure.
Cloud-native Application Data
Amazon S3 provides high performance, highly available storage that makes it easy to scale and maintain cost-effective mobile and Internet-based apps that run fast. With S3, you can add any amount of content and access it from anywhere, so you can deploy applications faster and reach more customers.
Amazon S3’s highly durable, secure, global infrastructure offers a robust disaster recovery solution designed to provide superior data protection. Cross-Region Replication (CRR) automatically replicates every S3 object to a destination bucket located in a different AWS region.
Hybrid Cloud Storage for Bursting, Tiering and Migration
The AWS Storage Gateway helps you build hybrid cloud storage, augmenting your existing local storage environment with the durability and scale of S3. Use it to burst a workload from your site into the cloud for processing and then bring the results back. Tier colder or less valuable data off of your primary storage into the cloud to lower costs and extend your on-prem investment. Or simply use it to incrementally move data into S3 as a part of backup or migration projects.
