Believe it or not, today marks the one-year anniversary of the Linkerd 2.0 launch! With 2.6 already round the corner, it’s hard to believe just how much momentum, adoption, and iteration has been packed into the last 365 days.

One year of Linkerd 2.x

Here are just a few of the highlights from the past year of Linkerd 2.x.

🍰 Solving real problems for real users. This November’s Kubecon San Diego includes talks from Linkerd users at Nordstrom, Disney, Microsoft, Paybase, and more, joining the ever-growing list of Linkerd production use cases that spans mobile to consumer to payments to banking. No matter the industry or scale, Linkerd gives you the essential reliability, security, and observability necessary to operate your app on Kubernetes. And most of all, it just works.

🍰 A non-stop drumbeat of releases. The past year has seen 5 stable releases of 2.x and 50 (!) edge releases, covering a changelog that spans over 2,000 lines of text! But don’t worry, you don’t have to read all that to use Linkerd… installing Linkerd is still a 60-second process.

🍰 An incredible pace of feature iteration. Since the 2.0 launch, we’ve added a on-by-default mutual TLS, per-route metrics, retries, timeouts, Helm charts, proxy auto-injection, traffic splitting, and many, many more features. That doesn’t even include the distributed tracing, tap headers, and TCP mTLS that are on the docket for later this year!

🍰 Mass ecosystem integrations. From OpenFaaS to Flagger to Ambassador to SuperGloo to DigitalOcean to VSCode to Rio, Linkerd has become a criticla building block for the cloud native ecosystem as a whole.

🍰 The creation of industry-defining interfaces. The Linkerd team was the largest contributor to Microsoft’s Service Mesh Interface specification, and Linkerd’s metrics and traffic splitting features support SMI out of the box.

🍰 A third-party security audit passed with flying colors. The security analysis firm Cure53 evaluated Linkerd and concluded that Linkerd “is fully capable of preventing major attacks and should be considered strong against the majority of malicious attempts at a compromise”, continuing that “Cure53 needs to mention the atypically excellent code readability, careful choice of implementation languages, as well as the clearly written and well-maintained documentation for all attributes.”

🍰 A third-party performance benchmark that placed it miles ahead of other projects. Kinvolk evaluated Linkerd’s performance, and concluded: “Linkerd takes the edge on resource consumption, and when pushed into high load situations, maintains acceptable response latency at a higher rate of requests per second that Istio is able to deliver.” (See our writeup of their report.)

🍰 A rapidly-growing, friendly, engaged community. Now at 4,500+ GitHub stars, 80 contributors, and 3,500+ friendly folks in the Linkerd Slack, the Linkerd community is consistently one of the friendliest and most helpful groups of humans you could find on the Internet!

But the most important thing of all?

I’m proud of all that we’ve accomplished, but the thing I’m most proud of, by far, is the consistent level of positive feedback and love we get Linkerd’s adopters, contributors, and committers. This is the oxygen that keeps any project growing, and above all, Linkerd is your project. Here’s to another incredible year together with you. πŸ’ͺ
