## What it is
Overlord is Bilibili's Go-based proxy and cluster management platform for memcache and Redis/Redis Cluster, providing an automated high-availability caching solution. It includes a lightweight proxy, a management platform with web GUI, and Redis cluster tooling for data sync and slot migration.

## Use cases
- proxy memcached and redis behind a single endpoint
- manage redis cluster scaling and slot migration
- replace twemproxy with redis-cluster support
- automate cache cluster creation and node expansion
- visualize and administer cache clusters via a web dashboard
- sync data between redis clusters

## When to choose
- you need a high-availability cache proxy for memcache and redis in production
- you want automated redis cluster management with a GUI
- you need redis-cluster protocol support in your proxy layer

## When to avoid
- you only need a simple single-node redis or memcached setup
- you rely on frequent upstream releases or non-Go tooling
- you want a fully managed cloud caching service

## Facets
- artifact type: service
- maturity: maintenance
- function: caching, proxy, api-gateway, deployment, http-server
