## What it is
A community-maintained lookup table mapping Google internal technologies and services to their external and open-source equivalents. It helps former Google engineers find real-world alternatives to internal tools like Borg, MapReduce, and Stubby.

## Use cases
- find open-source equivalents to Google internal systems
- map Google Cloud products to AWS or open-source alternatives
- onboard ex-Googlers to non-Google infrastructure
- compare distributed systems like Borg vs Kubernetes vs Mesos
- choose a pub/sub or RPC technology for a new project
- learn how Google internal tech relates to industry-standard tools

## When to choose
- you are an ex-Googler looking for equivalents to internal tools
- you want a quick reference comparing Google, cloud-vendor, and open-source technologies
- you are designing infrastructure and want to see the landscape of options

## When to avoid
- you need detailed documentation or tutorials rather than a mapping table
- you need up-to-date vendor pricing or product details
- you require a curated, opinionated recommendation rather than a broad list

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, documentation
- domain: developer-tools, infrastructure-as-code, cloud-computing, awesome-lists
- platform: cross-platform
- tags: cheatsheet, lookup-table, ex-googlers, infrastructure-mapping, reference-guide
