Istio vs linkerd: What are the differences?
Istio: Open platform to connect, manage, and secure microservices, by Google, IBM, and Lyft. Istio is an open platform for providing a uniform way to integrate microservices, manage traffic flow across microservices, enforce policies and aggregate telemetry data. Istio's control plane provides an abstraction layer over the underlying cluster management platform, such as Kubernetes, Mesos, etc; linkerd: 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.
Istio and linkerd can be categorized as "Microservices" tools.
Istio and linkerd are both open source tools. It seems that Istio with 18.5K GitHub stars and 3.1K forks on GitHub has more adoption than linkerd with 5.01K GitHub stars and 501 GitHub forks.
Envoy proxy is widely adopted in many companies for service mesh proxy, but it utilizes BoringSSL by default. Red Hat OpenShift fork envoy branch with their own OpenSSL support, I wonder any other companies are also using envoy-openssl branch for compatibility? How about AWS App Mesh?
Any input would be much appreciated!
Istio based on powerful Envoy whereas Kong based on Nginx. Istio is K8S native as well it's actively developed when k8s was successfully accepted with production-ready apps whereas Kong slowly migrated to start leveraging K8s. Istio has an inbuilt turn-keyIstio based on powerful Envoy whereas Kong based on Nginx. Istio is K8S native as well it's actively developed when k8s was successfully accepted with production-ready apps whereas Kong slowly migrated to start leveraging K8s. Istio has an inbuilt turn key solution with Rancher whereas Kong completely lacks here. Traffic distribution in Istio can be done via canary, a/b, shadowing, HTTP headers, ACL, whitelist whereas in Kong it's limited to canary, ACL, blue-green, proxy caching. Istio has amazing community support which is visible via Github stars or releases when comparing both.
