Weave vs linkerd: What are the differences?

<Write Introduction here>

1. Service Mesh Type: Weave is a Kubernetes native service mesh designed to provide network and observability for Kubernetes, while Linkerd is a service mesh for cloud-native applications, supporting both Kubernetes and non-Kubernetes environments.

2. Proxying Technology: Weave uses a sidecar proxy model for inter-service communication, where each service instance gets its own proxy container, while Linkerd uses a transparent proxy model where the proxy runs as a separate process on the host machine.

3. Latency Overhead: Weave typically has lower latency overhead compared to Linkerd due to its lightweight proxy containers, resulting in faster communication between services.

4. Feature Set: Weave focuses more on networking features such as service discovery, load balancing, and encryption, while Linkerd emphasizes observability features like metrics, tracing, and service-level objectives.

5. Community Support: Linkerd has a larger community support and user base compared to Weave, providing more extensive documentation, tutorials, and community-driven plugins.

6. Deployment Complexity: Weave offers a simpler deployment process with its Kubernetes-centric approach, making it easier to integrate with Kubernetes workloads, whereas Linkerd's deployment might require more configuration and setup for different environments.

In Summary, Weave and Linkerd differ in service mesh type, proxying technology, latency overhead, feature set, community support, and deployment complexity.
