## What are Compute Instances?

Compute instances are virtual machines running on our cloud infrastructure. They provide you with full control over your computing resources, operating system, and applications.

## Features

* **Multiple Operating Systems**: Ubuntu, Debian, CentOS, and more
* **Flexible Sizing**: Choose from 1GB RAM to 256GB RAM instances
* **SSD Storage**: Fast, reliable SSD storage up to 10TB
* **Snapshots**: Create point-in-time backups of your instances
* **Reserved IPs**: Assign static IP addresses
* **Load Balancing**: Distribute traffic across instances
