AWS S3 Endpoint URL for Website and API Access

To access your AWS S3 bucket as a website or API, you'll need to know the correct endpoint URL. This URL is used to connect to your bucket and interact with its contents.

The endpoint URL for an S3 bucket is in the format: https://s3.amazonaws.com/[bucket-name]. For example, if your bucket name is "my-bucket", the endpoint URL would be https://s3.amazonaws.com/my-bucket.

You can also use the AWS CLI to get the endpoint URL for your bucket. Simply run the command "aws s3 ls" to list all your buckets, and then note the endpoint URL for the bucket you want to access.

Your AWS account's region will also impact the endpoint URL. If your bucket is stored in the US East (N. Virginia) region, for example, the endpoint URL will be slightly different from one stored in the US West (Oregon) region.

An S3 Endpoint URL is a unique identifier that allows you to access your S3 bucket from a specific endpoint.

It's a combination of the bucket name and the endpoint name, separated by a slash, like this: bucket-name.endpoint-name.s3.amazonaws.com.

This URL is used to access your bucket from a specific region or edge location.

S3 endpoints can be used internally in Route 53 or CloudFront, or externally if your S3 bucket is publicly accessible.

Amazon S3 has two main ways to access your data: the website endpoint and the REST API endpoint. The website endpoint is used for hosting websites, while the REST API endpoint is used for sending requests to interact with S3.

The website endpoint is different from the REST API endpoint, and Amazon S3 can host websites. In fact, it has a robust API that can do lots of powerful things, including getting information about a bucket, creating a bucket, deleting a bucket, and more.

Here are some examples of what you can do with the REST API:

Understanding the difference between S3 website and REST API endpoints has been a challenge for many, including myself. But with practice and patience, you can master it and unlock the full potential of Amazon S3.

An S3 endpoint URL typically looks like a website endpoint, with a bucket name and region, such as bucket-name.s3-website-region.amazonaws.com.

In practice, an S3 API endpoint can be used with or without the website name in the URL, which can be confusing.

A virtual-hosted-style S3 REST endpoint uses the bucket name as the sub-sub-domain of the host URI, such as MyBucket.s3-us-east-1.amazonaws.com.

Using the bucket name in the URL, like in a virtual-hosted-style endpoint, is not the only way to choose a bucket, you can also use a target file.

A path-style S3 REST endpoint, on the other hand, uses the bucket name in the path of the URL, such as s3-us-east-1.amazonaws.com/MyBucket/index.html.

It makes no difference to S3 whether you choose a bucket by using a target file or the sub-sub-domain of the host URI.

S3 buckets can be made publically accessible, but this is not recommended as it poses a significant security risk.

To access an S3 bucket, you need to provide an AWS access key and secret access key, which can be obtained through the AWS Management Console.

You can also use AWS IAM roles to manage access to S3 buckets, which can be assigned to EC2 instances or other AWS services.

S3 bucket policies can be used to control access to specific objects within a bucket.

AWS Signature Version 4 is used for authenticating requests to S3, which involves signing the request with a signature that includes the access key, secret access key, and other information.

The S3 endpoint URL can be used to sign requests, which is required for cross-origin requests.

You can also use AWS Cognito to manage user identities and authenticate access to S3 buckets.

S3 bucket policies can be used to restrict access to specific objects within a bucket, such as restricting access to a specific object key.

If you're doing your DNS entry, such as a CNAME, to an S3 hosted site, you should use the website endpoint.

A good time to use the website endpoint is in the CloudFront Origin Setting, specifically in the Origin Domain Name field. This allows you to use S3 functions like routing rules and bucket policies.

You need to use the website endpoint if your S3 bucket is configured to be a website.
