HelloFresh: Navigating the rough seas of environment scaling with Aho
In the past couple of years, our engineering team at HelloFresh has experienced a huge growth spurt. Within 2 years our team grew from 35 engineers to well over 150. One of the biggest challenges we faced was how to enable over 20 teams to test their code independently to other teams in a stable environment.

I’m going to tell you about how we solved scaling our staging and local environments using phoenix environments.
The Problem
When we were smaller we had only 2 environments, what we called stagingand production. This setup was great for simple applications and small teams. Once we moved to a microservice architecture with 90+ services it quickly became apparent that it was not a scalable solution.
With more teams blocking staging for their testing, the environment quickly became unusable. The solution seemed simple, create an environment for each team called team staging.
Team Staging: Not the solution
We hoped that by creating a staging environment (which is a subset of all services from the main staging) for each team, it would enable them to test whatever they wanted in isolation. Or so we thought; in reality, it was much more complicated than that.

The complexity of modern problems often precludes any one person from fully understanding them. Factors contributing to rising obesity levels, for example, include transportation systems and infrastructure, media, convenience foods, changing social norms, human biology and psychological factors. Designing an aircraft carrier, to take another example, requires knowledge of nuclear engineering, naval architecture, metallurgy, hydrodynamics, […]
