How Does It Work?

Amazon S3 is a storage service that works with objects, buckets, and keys.

To store your data in Amazon S3, you’ll need to have your data in a bucket. Then, each object will have a key, which is the identifier for the object in the bucket.

You’ll be able to tailor this solution to match your needs, and you can even keep multiple versions of some data. That way, if something accidentally gets deleted, you can easily restore a previous version.

All of the buckets and objects are also private, and only people with permission can access them.

What Are Amazon S3 Buckets?

Amazon S3 buckets hold the objects. The buckets exist as a storage container for all of the objects.

In Amazon S3, you can create up to 100 buckets in each of your accounts. However, there’s no limit on how many objects you can store in each bucket. If you decide that you do need more buckets, you can submit a request for more.

To create a bucket, you’ll be able to choose which region of the storage you want to put it in. However, you should try and choose a region that is geographically close to you. This will help reduce your cost and also improve the speed of downloading the data.

Keep in mind that the object will stay in the bucket in a certain region until you want to transfer the file somewhere else. Also, each bucket is unique. No other account in that region will have the same bucket name as yours. However, to give your bucket name away, you’ll need to delete your own bucket.

What Are Objects?

Objects are what go inside the bucket. These are data files that will include your documents, videos, photos, and more. Each of them will have a unique key.

The maximum file size that an object can be is 160GB. However, some tools might let you add files that are even larger.

What Are Keys?

An object key is a unique identifier that’s within each bucket. Each bucket has about one key. The combination of the bucket, object key, and the version will help to identify each object.

Each object in Amazon S3 will be addressed through a combination of the bucket name, key, version, and the web service endpoint.

Unlike the bucket names, you can customize the key names.

If you’re a small business right now, Amazon S3 is still a great option. You can sign up for a certain amount of storage and network capacity. Which is similar to signing up for a certain amount of data on your cell phone.
