help AWS Elastic Compute Cloud (EC2) FAQ

What is an EC2 instance?

An EC2 instance is a virtual or bare-metal computing server rented through Amazon Web Services. You choose an instance type, an Amazon Machine Image, storage, networking, and security settings before launching it.

Can I run Windows and Linux on AWS EC2?

Yes. EC2 supports both Windows and Linux operating systems through different Amazon Machine Images and pricing configurations. The operating system can affect the hourly cost, especially for Windows instances that include a software license.

How do On-Demand and Spot EC2 instances differ?

On-Demand instances run at published rates without a long-term commitment, while Spot Instances use spare AWS capacity at a lower variable price. AWS can interrupt a Spot Instance when it needs the capacity, so Spot is better for interruptible workloads than for an always-on database.

What does an Elastic IP address do on EC2?

An Elastic IP is a persistent public IPv4 address that can be remapped to another EC2 instance when a server is replaced. This lets an application keep the same address while the underlying instance changes.
