The Cloud Native Computing Foundation, part of the Linux Foundation, is the home of Kubernetes and over 150 graduated, incubating and sandbox projects: Prometheus, Envoy, Helm, containerd, OpenTelemetry, Argo, Cilium, cert-manager, and most of the rest of the modern infrastructure stack.
Cloud native is where we started.
Kubernetes practitioners since "cloud native" was a niche conversation, on production platforms across media, finance, energy, travel and education.
Silver Membership grounded in delivery
YLD is a CNCF Silver Member.
The membership is more than a logo.
It reflects how we've been working for more than a decade: alongside our clients, in the open, with the conviction that the best technology is built and refined by communities. Our engineers contribute to open source across the cloud native ecosystem and engage with the CNCF Technical Advisory Groups whose remit overlaps with our work, particularly around platform engineering, security and observability.
We don't claim to be a Kubernetes Certified Service Provider.
That's a separate CNCF programme with its own criteria. Our credibility comes from the work, the community contributions, and the clients we've partnered with.
Where Kubernetes fits,
and where it doesn't
Kubernetes is the most successful distributed system ever built, and one of the easiest to misuse. It's the wrong answer for a small team with a single product who'd be better served by a managed platform. It's the right answer for organisations running multiple services at scale, with the operational maturity to support it.
We've migrated clients onto Kubernetes when it was the right call. We've talked clients out of it when it wasn't. Both conversations are part of the work.
Three principles guide how we engage. Kubernetes is infrastructure, not a product, which means the platform your product teams interact with is the one your team builds on top. Upstream first, custom last, because the CNCF catalogue has strong, widely-adopted building blocks for almost every problem a platform team faces. Operability beats novelty, because a production platform is judged on how it behaves at 3am, not on which new sandbox project it uses.

Rooted in open source, by design
Our engineers have made thousands of contributions to open source projects across the cloud native, JavaScript and data communities. We maintain libraries, speak at community events, and host meetups in London, Lisbon and Porto, including Design Systems London, ReactJS Girls, and require('lx'). Our teams attend KubeCon + CloudNativeCon and engage with the CNCF Technical Advisory Groups.

What CNCF membership delivers
in practice
Our engineers stay current because they learn from the people writing the standards. The advice is vendor-neutral: we recommend what fits your architecture and your business, not what someone is selling us. Investments age well because we build on open, portable, conformant technologies and standards, which keeps your options open as the technology evolves. Your teams grow through training, certifications and day-to-day collaboration on the same tools used by the world's most demanding platforms.
