Google Cloud Deploy vs Redgate Flyway

Google Cloud Deploy automates application delivery through an ordered set of target environments. It deploys to Google Kubernetes Engine, Cloud Run, GKE attached clusters, and custom targets, with releases promoted or rolled back through the web console, CLI, or API. Deployment options include canary and parallel rollouts, verification, deploy hooks, and automated promotion. IAM roles and conditions determine which authenticated users and service accounts can act. Cloud Audit Logs and Cloud Logging support audit trails and platform logs. Teams can invoke the service from CI through its CLI or API, including documented GitHub Actions and GitLab connections. Skaffold and Cloud Build render and deploy manifests, alongside artifact repositories and testing or workflow tools. The first active multiple-target pipeline each month costs nothing; each additional active multiple-target pipeline costs $5 a month per billing account. Underlying services may add charges. The regional system limit is 18,000 API requests per minute.
