## What it is
Weave Net is a container networking solution that creates a virtual overlay network connecting Docker containers across multiple hosts, clouds, and data centers with automatic service discovery. It can be used standalone with Docker or as a CNI plugin for Kubernetes.

## Use cases
- connect docker containers across multiple hosts
- kubernetes pod networking with a cni plugin
- network containers across cloud providers and data centers
- automatic service discovery for containerized microservices
- encrypt container traffic between hosts
- run portable microservices without configuring port mappings or links

## When to choose
- you need a simple resilient multi-host network for docker containers
- you want a kubernetes cni plugin with built-in encryption and discovery
- your containers span multiple clouds or data centers and must communicate as if on one switch

## When to avoid
- you need a high-performance cni plugin for large-scale clusters where calico or cilium may fit better
- you require active vendor support - weaveworks has shut down and the project is in maintenance mode
- you only run containers on a single host and docker's default networking suffices
