## What it is
Priam is a co-process from Netflix that runs alongside Apache Cassandra to automate backup/recovery, token management, seed discovery, and centralized configuration. It is designed for AWS environments, supporting multi-region Cassandra deployments with S3-based backups and REST APIs for operations.

## Use cases
- automate cassandra backups to s3
- restore cassandra cluster from backup
- manage cassandra token assignment automatically
- discover seed nodes in a cassandra cluster
- run multi-region cassandra on aws
- centralize cassandra configuration management
- schedule incremental sstable backups
- expose rest apis for cassandra backup and restore

## When to choose
- you run Apache Cassandra on AWS and want automated backup and recovery
- you need automated token management and seed discovery for Cassandra clusters
- you operate multi-region Cassandra deployments with public IP communication
- you want REST APIs to manage Cassandra cluster operations

## When to avoid
- you don't run Cassandra or don't deploy on AWS
- you use a managed Cassandra service that already handles backups and operations
- you need support for Cassandra versions outside the compatible branches
