Application Architecture: A Quick Guide for Startups

Application architecture is crucial for startups, as getting it right from the beginning can save significant headaches down the line. A typical startup application architecture consists of a user-facing front end, back end instances connected via a load balancer, and data passed horizontally to a data warehouse or vertically to a relational database. For high availability, modern applications often use active-active databases like CockroachDB, which distribute reads and writes across multiple nodes for better performance and resilience. When scaling to multiple regions, CockroachDB allows for multi-region deployments to be treated as a single logical database, ensuring optimal performance and availability. Building with distributed SQL databases from the outset can make it easier and more affordable to architect applications for scale, even if scaling is not immediately necessary.
