Netflix has integrated Temporal, a Durable Execution platform, to enhance its cloud operations, significantly reducing deployment failures. Initially adopted in 2021, Temporal allows developers to write code without having to constantly manage failures. This shift has been critical for various teams at Netflix, particularly those relying on their Open Connect global CDN and live service operations. The change has lowered transient deployment failures from 4% to an impressive 0.0001%. Before adopting Temporal, Netflix faced challenges with its deployment system, Spinnaker, which is a multi-cloud continuous delivery platform. Spinnaker relies heavily on microservices, with Orca managing the execution of deployment stages. Clouddriver, another key service, handles interactions with cloud infrastructure. The complexity of these interactions led to a high failure rate due to transient issues like network glitches. Clouddriver was burdened with intricate retry logic and a homegrown Saga framework to manage these failures, which only added to the system's cognitive load. The problems with Spinnaker prompted Netflix to seek a more reliable solution. Deployments could take days, and a mid-process failure required restarting the entire pipeline, which drained engineering productivity. By migrating to Temporal, Netflix could streamline its orchestration processes, allowing for more robust and reliable deployments without the excessive complexity that plagued their previous system. The transition involved not just adopting new technology but also refactoring legacy systems to align with the new architecture.
