We protect user data and maintain compliance with industry standards. As LinkedIn continues to grow, our systems need to scale efficiently. We design our architecture and processes to support this growth seamlessly.

Collaboration is also at the heart of our DevOps strategy. We break down silos between development operations and other teams to foster a collaborative environment. So now moving into a quick, uh, technical deep dive.

This is the high level topology of LinkedIn's continuous deployment. It has the, um, LCD front end, the LCD, uh, backend, and the, uh, client layers. We have designed this architecture in a modular fashion, so each component you see here is replaceable.

For example, we have a, a deployment policy engine, a one stop shop for all deployment related policies, which is built upon, uh, open policy agent. It is an open source and a strong industry, uh, community, uh, support platform, and it can be replaced with another policy engine without impacting other components of this architecture. So this architecture is low QPS system, but guarantees that deployment pipelines will execute with certainty, and if it fails, users will get alerted.

So what did we do differently? This time? We finally moved away from a legacy system that was, uh, over 10 years old.

We modernized orchestration engine. So we've remained, uh, so we've basically, uh, reimagined, uh, orchestration by leveraging cutting edge technologies to create and streamline engine that drives efficiency and flexibility.
