Google Artifact Registry
Pros
- + One registry for container images and language/OS packages with unified IAM and audit
- + Free storage tier (0.5 GiB per billing account/month) and cheap per-GiB pricing beyond it
- + Remote/virtual repositories proxy and cache public upstreams behind one endpoint
- + Deep GCP integration: GKE, Cloud Build, Binary Authorization, VPC Service Controls, CMEK
Cons
- - Management plane is GCP-only — poor fit for multi-cloud portability requirements
- - Cross-region data transfer charges ($0.01–$0.15/GiB) can surprise teams with scattered repos
- - Vulnerability scanning billed separately via Artifact Analysis; enabling the API bills both new and legacy products
- - No product-specific published SLA
Podman
Pros
- + Rootless by default — containers run without root, cutting the blast radius of a container escape
- + Daemonless architecture removes the privileged Docker socket and the daemon single point of failure
- + Docker CLI and Docker API compatibility keeps migration cheap for most workflows
- + Free under Apache 2.0 with CNCF governance — no licensing terms to audit
- + Quadlet/systemd integration gives clean boot and restart semantics for server workloads
Cons
- - Compose workflows are the weak spot — podman-compose is third-party and not always drop-in
- - Thinner third-party ecosystem; plenty of tooling still hardcodes Docker
- - macOS and Windows support runs through a VM and trails Docker Desktop on polish
- - Rootless networking and user-namespace edge cases need real investigation per workload
