Project Epsilon Overview

Payix. Saas Landing Page

Initially, Linear's infrastructure was concentrated in a single location - Google Cloud's us-east1. While this configuration served most users well, it presented long-term challenges. We identified two primary reasons to diversify our data hosting locations.

First, having a separate region with a full instance of the Linear application makes future scaling simpler. If we can host some workspaces in a particular infrastructure deployment (application servers, databases, etc.), then we can add other regions behind the scenes in the future to avoid hitting scaling limits on, for instance, the size of our primary Postgres server.

From the early beginnings of Linear, we’ve sought to invest in our foundation preemptively, always having an eye on potential future bottlenecks we might encounter. This enables us to build out the best possible infrastructure and application framework, without being forced to urgently implement sub-par solutions to scaling issues when we’re hitting those bottlenecks. This is also why we decided to tackle multi-region infrastructure earlier than other companies
