Amazon Simple Storage Service (Amazon S3) is an object storage service that offers industry-leading scalability, data availability, security, and performance. This means customers of all sizes and industries can use it to store and protect any amount of data for a range of use cases, such as websites, mobile applications, backup and restore, archive, enterprise applications, IoT devices, and big data analytics. Amazon S3 provides easy-to-use management features so you can organize your data and configure finely-tuned access controls to meet your specific business, organizational, and compliance requirements. Amazon S3 is designed for 99.999999999% (11 9's) of durability, and stores data for millions of applications for companies all around the world.
S3 gives you robust capabilities to manage access, cost, replication, and data protection. S3 Access Points make it easy to manage data access with specific permissions for your applications using a shared data set. S3 Replication features manage data replication within the region or to other regions. S3 Batch Operations helps manage large scale changes across billions of objects. S3 integration with Amazon Macie automatically provides an inventory of buckets and continually evaluates your S3 buckets to alert you to any unencrypted buckets, publicly accessible buckets, or buckets shared with AWS accounts. Since S3 works with AWS Lambda, you can log activities, define alerts, and automate workflows without managing additional infrastructure.
