Cellular architecture is a design pattern that helps achieve high availability in multi-tenant applications by deploying components into isolated cells. Each cell is autonomous, minimizing outages impact. Automation, including infrastructure as code and build pipelines, addresses key problems such as isolation, new cell creation, deployment, permissions, and monitoring. Request routing and monitoring are crucial for high availability. While theres no one-size-fits-all solution, individuals can choose tools and level of automation. For more information on cellular architecture and automation strategies, refer to Peter Voshall’s talk on minimizing blast radius of failures.
