Amazon ECS announces IPv6-only support

Amazon Elastic Container Service (Amazon ECS) now supports IPv6-only workloads, thus users can run containerized applications in IPv6-only environments without IPv4 dependencies while maintaining compatibility with existing applications and Amazon Web Services (AWS) services. Although Amazon ECS has previously supported IPv4 and dual-stack subnets, this new capability expands networking options to address emerging user needs.

Organizations worldwide are not only rapidly scaling their containerized applications but also facing IPv4 address exhaustion challenges, leading to service disruptions and deployment delays. In IPv4 networks, containers in private subnets need NAT gateways for internet access, adding operational complexity through multi-AZ deployments, ongoing configuration, and increased costs from NAT gateway hours and public IPv4 address charges. Furthermore, many organizations, particularly federal agencies, now face regulatory requirements mandating IPv6 adoption.
