# Tech Stack & Architecture

Have you worked at a company with **40+ datacenters all around the world**? Great, a lot of people haven't worked at that scale so we think it's important to show the [scale of our systems](https://infobipengineering.gitbook.io/handbook/tech-stack-and-architecture/the-scale-of-our-systems) and the many [layers of our platform architecture](https://infobipengineering.gitbook.io/handbook/tech-stack-and-architecture/platform-architecture). We also shouldn't forget that [observability is a crucial factor](https://infobipengineering.gitbook.io/handbook/tech-stack-and-architecture/observability-for-quality) that let us #develop faster on the tech stack that we hope you'll be working on soon as well.
