Envoy Proxy
Pros
- + Free forever: Apache 2.0, no seats, no per-node licence, no usage metering
- + CNCF graduated with neutral governance and multi-vendor support options
- + xDS APIs are the de facto standard control-plane interface for service meshes and gateways
- + Depth of features: HTTP/3, gRPC-aware load balancing, circuit breaking, external auth, rate limiting, hot cert rotation
- + Documented support window (four minor versions patched) and a decade of production track record
- + Extensive observability hooks: stats, tracing headers, structured access logs
Cons
- - Configuration complexity is high; production-grade setups need a control plane or serious in-house expertise
- - No SLA or commercial support bundled — community support only
- - Sidecar overhead (latency and memory per proxy) is a real cost in large mesh deployments
- - C++ codebase narrows the pool of people who can debug core-level issues
- - Troubleshooting spans both Envoy docs and whatever control plane generates your config
GitHub Container Registry
Pros
- + Free storage and bandwidth for public images with anonymous pulls — strongest OSS distribution offer
- + Images live with the code: one account, one permission model, GITHUB_TOKEN in Actions
- + OCI-compliant (Docker V2 manifests, foreign layers), internal visibility and fine-grained package permissions
- + Container image storage currently free even for private images, with a one-month notice policy before changes
- + Spending limits available to cap overage; metered billing beyond plan quotas
Cons
- - Private plan quotas are small (500 MB on Free) and shared with GitHub Actions artifacts
- - Free private container storage is a policy, not a contract — changeable with one month's notice
- - No published SLA or regional placement for ghcr.io
- - Retention and promotion tooling lag purpose-built registries like Harbor or Artifactory
