## What it is
Ambry is a distributed object store from LinkedIn designed to store and serve trillions of small immutable objects (50K-100K) as well as billions of large objects, optimized for media in web companies. It is highly available, horizontally scalable, and supports active-active multi-datacenter deployments with asynchronous replication.

## Use cases
- store and serve media objects like photos and videos at scale
- store database backups
- store search indexes
- store business reports
- build a highly available blob storage backend for CDN origin serving
- store billions of large immutable objects across datacenters

## When to choose
- you need to store and serve trillions of small immutable objects or billions of large ones with low latency
- you need an active-active, multi-datacenter, eventually consistent storage system
- you want a cost-effective, horizontally scalable origin store for CDN-served media

## When to avoid
- you need strongly consistent mutable object storage
- you want a turnkey managed cloud storage solution rather than self-operating a distributed cluster
- your stack is not JVM-based, since Ambry requires JDK 1.11-1.14
