Peerd enhances Azure Artifact Streaming and containerd image pull performance by enabling peer-to-peer distribution in a Kubernetes cluster. Nodes can share streamable content as well as images with each other, which can result in throughput and latency improvements.
| Benefit | Artifact Streaming | Image Pulls | Notes |
|---|---|---|---|
| Increased Throughput | ✅ |
✅ |
Both streaming and image pull latency improves. |
| Reduced Cluster Scale Out Time | ✅ |
✅ |
New nodes stream or pull images from peers that already have that content. |
| Improved Cluster Fault Tolerance | ✅ |
✅ |
Mitigating upstream throttling or unavailability. |
| Reduced Container Registry Egress Costs | ✅ |
✅ |
By sharing content within the cluster, upstream I/O is reduced. |
| More Cluster Firewall Configuration Options | ✅ |
✅ |
Once an image or streamable content is ingested, nodes can share from each other without needing to communicate with the container registry. |
| Ease of Use | ✅ |
✅ |
Peerd is a drop-in solution that requires no changes to existing workflows or tooling, with seamless fallback to the container registry if needed. |
