AWS AppConfig adds enhanced targeting during feature flag rollout

AWS AppConfig enhances its deployment capabilities with new controls that allow customers to target feature flag and configuration data values to specific segments or individual users during the lifecycle of a gradual roll-out.

One of AWS AppConfig’s key safety guardrails is the ability for customers to roll out feature flag or configuration data changes slowly, over the course of minutes or hours. This progressive delivery allows customers to move safer, and limit the impact of unexpected changes. AWS AppConfig uses customer-provided entity identifiers to make specific feature flag or dynamic configuration data “sticky” to individual target segments during the lifecycle of these gradual roll-outs. This targeting capability, using AppConfig Agent, ensures fine-grained control, including using an individual user ID or IDs, while updates are being deployed.
