This article introduces Linkerd 2.4 to bring traffic segmentation and SMI is how, the content is very detailed, interested friends can refer to, hope to be helpful to you.

We are pleased to announce the release of Linkerd 2.4. This version adds traffic segmentation and Service Grid Interface (Service Mesh Interface,SMI) support, high availability support is out of the lab state to graduation, and includes a number of other improvements, performance enhancements, and bug fixes.

Did I mention that Linkerd recently passed a third-party security audit? )

Linkerd's new traffic segmentation feature allows users to dynamically control the percentage of service traffic. This powerful feature can implement strategies such as grayscale and blue-green deployment through the incremental transfer of request traffic between Kubernetes services.

Support for service grid interfaces makes it easier for ecosystem tools to use Linkerd. This has paid off: we are pleased to report that Flagger now supports Linkerd! Flagger is a progressive delivery operator (Operator) that combines metrics and traffic segmentation and is a good example of high-level operations based on a service grid. The Linkerd team is the biggest contributor to SMI, so we are pleased to see it all coming together so perfectly. )

Finally, Linkerd 2.4 graduated the high availability (high availability,HA) control plane mode from the experimental state to a fully productive feature and introduced a number of other improvements, performance enhancements, and fixes, including:

New linkerd edges command to audit the TLS and identity of connections between resources

The installation process is divided into two phases, which separates the privilege requirements at the cluster level and the namespace level for security-conscious Kubernetes adopters, and does not allow anyone to change the content on the cluster.

Debug the side car (sidecar) to facilitate checking pod traffic

The new security audit from Cure53 passed smoothly.

For more information, please read the complete Linkerd 2.4 release notes for more details!

Linkerd 2.4 is our third major release in 2019. Earlier this year, Linkerd 2.3 enabled mutual TLS by default, making authenticated, confidential communication between gridding services the standard for all Linkerd users. In February, Linkerd 2.2 introduced automatic retry and timeout, adding a powerful reliability mechanism that allows Linkerd users to automatically recover from many local failures unique to distributed systems.

We will discuss 2. 4 interesting features and 2. 5 plans at the Linkerd online community meeting later this month. Be sure to come to our event.
