A huge milestone for zero-trust security, Linkerd 2.9 extends its zero-config mTLS support to all TCP connections. Linkerd now encrypts and authenticates all TCP connections in the cluster at installation. This includes automatic certification rotation and strong pod identity guarantees. This release also adds ARM support, a new multi-core proxy runtime for higher throughput, as well as support for Kubernetes service topologies, and more.
Check out this webinar to hear from Linkerd creator Oliver Gould about what this means for the CNCF’s most popular service mesh project.
