Cell-based architectures are a resilient system approach that reduces failure impact by using fixed-size cells as deployment units, favoring scale-out over scale-up. They improve security by isolating components, offering a clearer system view. Many companies revisit cell-based architecture to address outages. Major players like Slack, Doordash, and Roblox have made the switch for efficiency and resiliency as they scale. Cell-based architecture combines domain and fault isolation effectively. Despite challenges, adopting a cell-based approach can enhance the system’s resiliency, scalability, and deployment flexibility. Considerations for adopting this approach include the ability to handle widespread outages, maintain low RPO/RTO, and provide tenant-level isolation.
