Today, AWS launched automatic handling of IP address changes for Refactor Spaces Services. Customers use automatic DNS updates to avoid building infrastructure to manage service IP address changes and gain improved operational safety. This new feature lets customers create services using DNS names in the URL and Refactor Spaces automatically re-resolves the DNS name when the DNS time-to-live (TTL) expires (or every 60 seconds for TTLs less than 60 seconds).

Refactor Spaces now handles more of the infrastructure needed for multi-account HTTP routing, so you can focus on safely and incrementally refactoring your application. Prior to this launch, customers who wanted to route traffic to services with IPs that might change (e.g. Application Load Balancer) had to set up custom mechanisms, like AWS Lambda functions, to manage IP address changes. Starting today, you can use a DNS name in the Refactor Spaces Service URL without needing to actively manage IP address changes. There is no additional cost for automatically re-resolving service URLs with DNS names.

AWS Migration Hub Refactor Spaces is the starting point for incremental application refactoring to microservices in AWS. Refactor Spaces automates the creation of application refactor environments including all of the infrastructure, multi-account networking, and routing to incrementally modernize. Use Refactor Spaces to help reduce risk when evolving applications into microservices or extending existing applications with new features written in microservices.

This feature is available in all Regions where Refactor Spaces is available. To learn more about AWS Migration Hub Refactor Spaces, please see the documentation.
