# AWS Resource Groups and Tagging endpoints and quotas
To connect programmatically to an AWS service, you use an endpoint. AWS services offer the following endpoint types in some or all of the AWS Regions that the service supports: IPv4 endpoints, dual-stack endpoints, and FIPS endpoints. Some services provide global endpoints. For more information, see [AWS service endpoints](rande.md).
Service quotas, also referred to as limits, are the maximum number of service resources or operations for your AWS account. For more information, see [AWS service quotas](aws_service_limits.md).
The following are the service endpoints and service quotas for this service.
