As discovery closes, your focus shifts to leading the platform migration : standing up the target collection pipeline and storage tiers, porting log transforms to OpenTelemetry, rebuilding dashboards and alerts, and establishing policy-driven retention and ownership tagging that make observability both less expensive and more useful. Target Architecture: Design the AWS-native target across collection (ADOT / OpenTelemetry Collector), pipeline (Amazon Data Firehose), storage tiering (CloudWatch, S3, Amazon Managed Service for Prometheus), query surfaces (Amazon Managed Grafana, CloudWatch, Athena, OpenSearch), and alerting.
