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
Africa (Cape Town)	af-south-1
Asia Pacific (Hong Kong)	ap-east-1
Asia Pacific (Hyderabad)	ap-south-2
Asia Pacific (Jakarta)	ap-southeast-3
Asia Pacific (Malaysia)	ap-southeast-5
Asia Pacific (Melbourne)	ap-southeast-4
Asia Pacific (Mumbai)	ap-south-1
Asia Pacific (Osaka)	ap-northeast-3
Asia Pacific (Seoul)	ap-northeast-2
Asia Pacific (Singapore)	ap-southeast-1
Asia Pacific (Sydney)	ap-southeast-2
Asia Pacific (Taipei)	ap-east-2
Asia Pacific (Thailand)	ap-southeast-7
Asia Pacific (Tokyo)	ap-northeast-1
Canada (Central)	ca-central-1
Canada West (Calgary)	ca-west-1
Europe (Frankfurt)	eu-central-1

Middle East (Bahrain)	me-south-1
Middle East (UAE)	me-central-1
South America (São Paulo)	sa-east-1
AWS GovCloud (US-East)	us-gov-east-1
AWS GovCloud (US-West)	us-gov-west-1

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

The following services each have a global endpoint that spans AWS Regions:

• AWS Cloud WAN

• Amazon CloudFront

• AWS Global Accelerator

• AWS Identity and Access Management (IAM)

• AWS Organizations

• Amazon Route 53

• AWS Shield Advanced

• AWS WAF Classic

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:

• Open Service endpoints and quotas, search for the service name, and click the link to open the page for that service. To view the supported endpoints for all AWS services in the documentation without switching pages, view the information in the Service Endpoints and Quotas page in the PDF instead.

• To programmatically check for service availability using the SDK for Java, see Check for service availability in an Region in the AWS SDK for Java Developer Guide.

• To programmatically view Region and service information using Systems Manager, see Calling public parameters for AWS services, Regions, endpoints, and zones in parameter store in the AWS Systems Manager User Guide. For information about how to use public parameters, see Query for AWS Regions, Endpoints, and More Using AWS Systems Manager Parameter Store.

• To see the supported AWS services in each Region (without endpoints), see the Region Table.

FIPS endpoints

Some AWS services offer endpoints that support Federal Information Processing Standard (FIPS) 140-2 in some Regions. Unlike standard AWS endpoints, FIPS endpoints use a TLS software library that complies with FIPS 140-2. 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 enable the use of FIPS endpoints:

• Set the AWS_USE_FIPS_ENDPOINT environment variable to true

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

The AWS Command Line Interface supports these 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. For information about how to determine whether your applications were impacted 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 its dual stack endpoints.

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

To make a request to a dual stack endpoint, you must use the mechanism provided by the tool or AWS SDK to specify the endpoint. For example, 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

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