Today (in addition to some other exciting news) we’re happy to announce the release of Linkerd 1.1.1, which features integration with the Istio project! This…

In previous posts in this series, we’ve demonstrated how Linkerd can act as an ingress to a Kubernetes cluster, handling all requests coming from outside of the…

As part of our Linkerd 1.0 release last month, we snuck in something that a few people have picked up on—Linkerd’s service mesh API. With the…

Beyond service discovery, top-line metrics, and TLS, linkerd also has a powerful routing language, called dtabs, that can be used to alter the ways that requests—even…

Today, we’re thrilled to announce Linkerd version 1.0. A little more than one year from our initial launch, Linkerd is part of the Cloud Native Computing Foundation and…

tl;dr: A service mesh is a dedicated infrastructure layer for making service-to-service communication safe, fast, and reliable. If you’re building a cloud native application, you…

As of Linkerd 0.8.5, released earlier this year, Linkerd supports gRPC and HTTP/2! These powerful protocols can provide significant benefits to applications that make use of…

Linkerd is designed to make service-to-service communication internal to an application safe, fast and reliable. However, those same goals are also applicable at the edge.…

Yesterday, at Kubecon EU, I announced an exciting new project in the Linkerd family: Linkerd-tcp. Linkerd-tcp is a lightweight, service-discovery-aware, TLS-ing TCP load balancer that integrates directly…

Linkerd’s role as a service mesh makes it a great source of data around system performance and runtime behavior. This is especially true in polyglot or heterogeneous…

We’re happy to announce that, one year after version 0.1.0 was released, Linkerd has processed over 100 billion production requests in companies around the world. Happy birthday, Linkerd! Let’s…

Today we’re happy to release Linkerd 0.9.0, our best release yet! This release is jam packed with internal efficiency upgrades and major improvements to the…

The development of distributed systems is full of strange paradoxes. The reasoning we develop as engineers working on a single computer can break down in…

Cross-posted on the Cloud Native Computing Foundation blog. Today, the Cloud Native Computing Foundation’s (CNCF) Technical Oversight Committee (TOC) voted to accept linkerd as its fifth hosted project, alongside Kubernetes, Prometheus, OpenTracing and Fluentd.…

One of the inevitabilities of moving to a microservices architecture is that you’ll start to encounter partial failures—failures of one or more instances of a service.…

In March 2016 at Kubecon EU, I gave my my first public talk on linkerd. At the end of this talk, like most of the other…

Staging new code before exposing it to production traffic is a critical part of building reliable, low-downtime software. Unfortunately, with microservices, the addition of each…

Linkerd, our service mesh for cloud-native applications, needs to handle very high volumes of production traffic over extended periods of time. In this post, we’ll…

We’re happy to announce that we’ve released linkerd 0.8.4! With this release, two important notes. First, Kubernetes and Consul support are now officially production-grade features—high time…

In this post we’ll show you how to use a service mesh of linkerd instances to handle ingress traffic on Kubernetes, distributing traffic across every…

In this article, we’ll show you how to use linkerd as a service mesh to add TLS to all service-to-service HTTP calls, without modifying any…

In our recent post about linkerd on Kubernetes, A Service Mesh for Kubernetes, Part I: Top-line Service Metrics, observant readers noticed that linkerd was installed using…

In our previous post, linkerd as a service mesh for Kubernetes, we showed you how to use linkerd on Kubernetes for drop-in service discovery and monitoring.…

What is a service mesh, and how is it used by cloud native apps—apps designed for the cloud? In this article, we’ll show you how…

In this post, we’ll describe how we reduced the memory footprint of linkerd, our JVM-based service mesh for cloud-native applications, by almost 80%—from 500mb to 105mb—by tuning the JVM’s…

Version 0.6.0 of linkerd and namerd were released today! We wanted to take the opportunity in this release to bring more consistency and uniformity to…

Distributed tracing is a critical tool for debugging and understanding microservices. But setting up tracing libraries across all services can be costly—especially in systems composed…

Microservices allow engineering teams to move quickly to grow a product… assuming they don’t get bogged down by the complexity of operating a distributed system.…

As part of the launch of DC/OS, the open source Mesos ecosystem from Mesosphere, Buoyant, and dozens of other companies, we’re happy to announce the launch…

In this post, we describe how linkerd, our service mesh for cloud-native applications, can be used to transparently “wrap” HTTP and RPC calls in TLS, adding a…

This post was co-written with Ruben Oanta. Load balancing is a critical component of any large-scale software deployment. But there are many ways to do load…

How do you operate modern, cloud-native applications at scale? What problems arise in practice, and how are they addressed? What is actually required to run a cloud-native,…
