linkerd vs Rancher: What are the differences?
Developers describe linkerd as "Twitter-Style Operability for Microservices". linkerd is an out-of-process network stack for microservices. It functions as a transparent RPC proxy, handling everything needed to make inter-service RPC safe and sane--including load-balancing, service discovery, instrumentation, and routing. On the other hand, Rancher is detailed as "Open Source Platform for Running a Private Container Service". Rancher is an open source container management platform that includes full distributions of Kubernetes, Apache Mesos and Docker Swarm, and makes it simple to operate container clusters on any cloud or infrastructure platform.
linkerd belongs to "Microservices Tools" category of the tech stack, while Rancher can be primarily classified under "Container Tools".
Some of the features offered by linkerd are:
- Adaptive load-balancing
- Fine-grained instrumentation
- Abstractions over service discovery
On the other hand, Rancher provides the following key features:
- Manage Hosts, Deploy Containers, Monitor Resources
- User Management & Collaboration
- Native Docker APIs & Tools
linkerd and Rancher are both open source tools. It seems that Rancher with 11.8K GitHub stars and 1.31K forks on GitHub has more adoption than linkerd with 5K GitHub stars and 499 GitHub forks.
