Argo Rollouts vs Redgate Flyway

Argo Rollouts is a self-hosted Kubernetes controller for managing how application updates reach users. It supports BlueGreen, Canary and Rolling Update strategies, with weighted traffic shifting through ingress controllers or service meshes. Without a traffic-routing provider, it can adjust ReplicaSet counts instead. Metric integrations let it assess KPIs and automate promotion or rollback, while leaving room for manual judgment. Supported providers include NGINX, AWS ALB, Istio and Traefik for traffic, and Prometheus, Datadog, New Relic, Graphite and InfluxDB for metrics. It can operate independently of Argo CD and respond to Kubernetes manifest changes whether they come from GitOps or traditional CI/CD. Each cluster running Rollout workloads needs its own controller and CRD; a Rollout specification covers one application, not dependencies among applications. Shared-resource or worker-queue applications may be a poor fit, and infrastructure applications are not recommended. Argo Rollouts is free and open source. It runs on Linux, macOS, Windows or self-hosted environments.
