Amazon Simple Storage Service (Amazon S3) is an object storage service that offers industry-leading scalability, data availability, security, and performance. You can use Amazon S3 to store and retrieve any amount of data at any time, from anywhere.
To get the most out of Amazon S3, you need to understand a few simple concepts. Amazon S3 stores data as objects within buckets. An object consists of a file and optionally any metadata that describes that file. To store an object in Amazon S3, you upload the file you want to store to a bucket. When you upload a file, you can set permissions on the object and any metadata.
Buckets are the containers for objects. You can have one or more buckets. For each bucket, you can control access to it (who can create, delete, and list objects in the bucket), view access logs for it and its objects, and choose the geographical region where Amazon S3 will store the bucket and its contents.
Set up and log into your AWS account
To use Amazon S3, you need an AWS account If you don't already have one, you'll be prompted to create one when you sign up for Amazon S3. You will not be charged for Amazon S3 until you use it.
Create a bucket
Every object in Amazon S3 is stored in a bucket. Before you can store data in Amazon S3, you must create an S3 bucket.
Start building with AWS
Now that you've created a bucket, you're ready to add an object to it. An object can be any kind of file: a text file, a photo, a video, and so on. Read the Getting Started Guide to learn more and start building.
Using the AWS SDK
Developers building applications can choose from a wide variety of AWS SDKs that simplify using Amazon S3 in their use case. AWS SDKs for Amazon S3 include libraries, code samples, and documentation for the following programming languages and platforms.

With Amazon S3 Object Lambda, you can add your own code to S3 GET, HEAD, and LIST requests to modify data as it is returned to an application. You can use custom code to modify the data returned by S3 GET requests to convert data formats, dynamically resize images, redact confidential data, and much more.

Moving data to Amazon S3
AWS provides a portfolio of data transfer services to provide the right solution for any data migration project. The level of connectivity is a major factor in data migration, and AWS has offerings that can address your hybrid cloud storage, offline data transfer, and online data transfer needs.
Hybrid cloud storage
Offline data transfer
The AWS Snow Family is comprised of AWS Snowcone, AWS Snowball, and AWS Snowmobile. AWS Snowcone and AWS Snowball are small, rugged, and secure portable storage and edge computing devices for data collection, processing, and migration. These devices are purpose-built for use in edge locations where network capacity is constrained or nonexistent and provide storage and computing capabilities in harsh environments. AWS Snowmobile is an exabyte-scale data transfer service used to move massive volumes of data to the cloud, including video libraries, image repositories, or even a complete data center migration.
Online data transfer
AWS DataSync makes it easy and efficient to transfer hundreds of terabytes and millions of files into Amazon S3, up to 10x faster than open-source tools. DataSync automatically handles or eliminates many manual tasks, including scripting copy jobs, scheduling and monitoring transfers, validating data, and optimizing network utilization. Using Snowcone, you can even transfer data online with AWS DataSync from edge locations.
The AWS Transfer Family provides fully managed, simple, and seamless file transfer to Amazon S3 using SFTP, FTPS, and FTP.
Amazon S3 Transfer Acceleration enables fast transfers of files over long distances between your client and your Amazon S3 bucket. Amazon Kinesis and AWS IoT Core make it simple and secure to capture and load streaming data from IoT devices to Amazon S3.
