AWS service endpoints - AWS General Reference

AWS service endpoints

To connect programmatically to an AWS service, you use an endpoint. An endpoint is the URL of the entry point for an AWS web service. The AWS SDKs and the AWS Command Line Interface (AWS CLI) automatically use the default endpoint for each service in an AWS Region. But you can specify an alternate endpoint for your API requests.

If a service supports Regions, the resources in each Region are independent of similar resources in other Regions. For example, you can create an Amazon EC2 instance or an Amazon SQS queue in one Region. When you do, the instance or queue is independent of instances or queues in all other Regions.

Regional endpoints

Most Amazon Web Services offer a Regional endpoint that you can use to make your requests. In general, these endpoints support IPv4 traffic and they use the following syntax.

protocol://service-code.region-code.amazonaws.com

For example, https://dynamodb.us-west-2.amazonaws.com is the endpoint for the Amazon DynamoDB service in the US West (Oregon) Region.

The following table lists the name and code of each Region.

Name Code
US East (Ohio) us-east-2
US East (N. Virginia) us-east-1
US West (N. California) us-west-1
US West (Oregon) us-west-2

General endpoints

The following services support Regional endpoints but also support a general endpoint that doesn't include a Region. When you use a general endpoint, AWS routes the API request to US East (N. Virginia) (us-east-1), which is the default Region for API calls.

  • Amazon EC2 – ec2.amazonaws.com

  • Amazon EC2 Auto Scaling – autoscaling.amazonaws.com

  • Amazon EMR – elasticmapreduce.amazonaws.com

Global endpoints

Note that some of these services have additional endpoints, such as FIPS endpoints.

View the service endpoints

You can view the AWS service endpoints using the following options:

FIPS endpoints

Some AWS services offer endpoints that support Federal Information Processing Standard (FIPS) 140 in some Regions. Unlike standard AWS endpoints, FIPS endpoints use a TLS software library that complies with FIPS 140. These endpoints might be required by enterprises that interact with the United States government.

To specify a FIPS endpoint when you call an AWS operation, use a mechanism provided by the tool that you're using to make the call. For example, the AWS SDKs provide the following mechanisms to use FIPS endpoints:

  • Set the AWS_USE_FIPS_ENDPOINT environment variable to true

  • Add use_fips_endpoint=true to your ~/.aws/config file

For information about FIPS endpoint support in AWS SDKs, see Dual-stack and FIPS endpoints in the AWS SDKs and Tools Reference Guide.

The AWS Command Line Interface supports the preceding mechanisms, and also provides the --endpoint-url option. The following example uses --endpoint-url to specify the FIPS endpoint for AWS Key Management Service (AWS KMS) in the US West (Oregon) Region.

aws kms create-key --endpoint-url https://kms-fips.us-west-2.amazonaws.com

For a list of FIPS endpoints, see FIPS endpoints by Service.

Minimum TLS version for FIPS endpoints

With FIPS endpoints, the minimum requirement is TLS 1.2. We recommend TLS 1.3. To determine whether your applications were affected by this change, see this AWS Security Blog post.

Dual stack endpoints

Some AWS services offer dual stack endpoints, so that you can access them using either IPv4 or IPv6 requests. In general, the syntax of a dual stack endpoint is as follows:

protocol://service-code.region-code.api.aws

However, Amazon S3 uses the following syntax for Amazon S3 dual stack endpoints:

protocol://service-code.dualstack.region-code.amazonaws.com

To make a request to a dual stack endpoint, use the mechanism provided by the tool or AWS SDK to specify the endpoint. For information about dual stack endpoint support in AWS SDKs, see Dual-stack and FIPS endpoints in the AWS SDKs and Tools Reference Guide.

The AWS CLI provides the --endpoint-url option. The following example uses --endpoint-url to specify the dual stack endpoint for Amazon EC2 in the US West (Oregon) Region.

aws ec2 describe-regions --region us-west-2 --endpoint-url https://ec2.us-west-2.api.aws

To use the AWS CLI to configure dual-stack endpoints for all AWS services, see Set to use dual-stack endpoints for all AWS services in the AWS Command Line Interface User Guide.

For a list of services that support dual stack endpoints, see AWS services that support IPv6.
