In the Amazon S3 Console inside AWS Management, you can easily manage objects and buckets. No other AWS account in the same region can have the same bucket names as yours unless you first delete your own buckets. It’s also important to know that Amazon S3 buckets are globally unique. Objects that reside in a bucket within a specific region remain in that region unless you transfer the files elsewhere. To minimize costs and address latency concerns, it’s best practice to select a region that’s geographically closest to you. When you create a bucket, you have the ability to choose the AWS region to store it in. If needed, you can request up to 1,000 more buckets by submitting a service limit increase. You can create up to 100 buckets in each of your AWS cloud accounts, with no limit on the number of objects you can store in a bucket. In an S3 environment, objects need somewhere to go, which is why buckets exist, serving as fundamental storage containers for objects. The maximum object file size is 160 GB for uploading, however there are various AWS tools to help you add files larger than this. Each object is identified by a unique key within the S3 environment that differentiates it from other stored objects. Amazon S3 ObjectsĪs mentioned above, in Amazon S3 terms, objects are data files, including documents, photos, and videos. As AWS describes it, an S3 environment is a flat structure - a user creates a bucket the bucket stores objects in the cloud. Organizing, storing and retrieving data in Amazon S3 focuses on two key components: buckets and objects that work together to create the storage system. Use cases include websites, mobile apps, archiving, data backups and restorations, IoT devices, enterprise application storage, and providing the underlying storage layer for your data lake. Organizations of any size in any industry can use this service. What is Amazon S3?Īmazon S3 is a program that’s built to store, protect, and retrieve data from “buckets” at any time from anywhere on any device. In this blog, we will give you an understanding of the Amazon Simple Storage Service (Amazon S3), why it is such an important and foundational service - and most importantly, how it provides the underlying storage layer for your data lake in AWS. No matter where you are in the process of moving to the AWS cloud, from consideration to the migration process, it’s always important to learn more about what it is, how it works, and how you can optimize it for your organization.
