AWS CodeDeploy vs Weave GitOps

AWS CodeDeploy automates application releases across development, test, and production environments. It deploys to Amazon EC2, AWS Fargate, AWS Lambda, and on-premises instances using in-place, canary, or blue/green methods. Rolling updates and deployment health tracking help limit disruption; when too many updates fail, CodeDeploy can stop a deployment and restore a previous revision. Teams can launch and monitor releases through the AWS Management Console, CLI, SDKs, or APIs. AWS CodePipeline and some AWS partners offer prebuilt CI/CD connections. For EC2, CodeDeploy works with Auto Scaling and can update an instance before it joins an Elastic Load Balancing load balancer. Amazon SNS can send deployment-event notifications by SMS or email. The service uses a file- and command-based installation model with an AppSpec configuration file and is platform and language agnostic. EC2 deployments have no additional CodeDeploy charge; on-premises updates cost $0.02 per instance update, with no minimum fees or upfront commitments. On-premises instances must connect to public AWS service endpoints. The free plan is listed at free.

Weave GitOps extends Flux with deployment insights and tools for continuous delivery across teams. Its dashboard lets operators inspect application lifecycles, detect drift, check cluster health, roll back changes, and monitor operations. Both Open Source and Enterprise require a running Kubernetes cluster. The free Open Source edition includes a GitOps CLI for macOS and Linux. Enterprise adds deployment across multiple clusters in cloud and hybrid environments using Git and Cluster API. It supports canary, blue/green, and A/B rollouts, with success and rollback criteria based on metrics from Prometheus, Datadog, or New Relic. Enterprise also offers policy-as-code checks at commit, build, deploy, and runtime stages, plus team workspaces, multi-tenancy, role-based access, and enterprise identity integration. OIDC login and Kubernetes RBAC govern access. Infrastructure integrations include Terraform, Crossplane, and any Cluster API provider. Enterprise advertises critical 24/7 support for workloads and requires an entitlement from Weaveworks. The Open Source installation guide notes that dashboard login sessions are not persisted when scaling to multiple replicas.
