Ever wondered how Semaphore manages to juggle thousands of CI/CD pipelines with such finesse? Dive into the world of Semaphore's Plumber engine, where Elixir and Finite State Machines (FSMs) come together to create a powerhouse of scalability and reliability. This innovative approach not only streamlines workflows but also enhances collaboration among teams, ensuring that code moves smoothly from development to production. As a data scientist, I find the intersection of programming and operational efficiency fascinating—it's a perfect example of how technology can transform processes. What challenges do you think teams face when scaling their CI/CD pipelines, and how might solutions like Plumber address these issues? Let’s discuss!
