aws ec2 command [options]

aws ec2 is the AWS CLI interface for Amazon Elastic Compute Cloud (EC2), providing programmatic access to scalable compute capacity. EC2 enables launching virtual servers, configuring networking and security, and managing storage.
EC2 commands cover instance lifecycle management, Amazon Machine Images (AMIs), Elastic Block Store (EBS) volumes, VPC networking, security groups, and key pairs. The service supports on-demand, reserved, and spot pricing models.

run-instances

Launch new EC2 instances

List and describe instances

Start stopped instances

Stop running instances

Permanently delete instances

Create an AMI from an instance

Create a security group

Add inbound rules to security group

Generate a new key pair

Create a Virtual Private Cloud

Create an EBS volume

Attach volume to an instance

Instances continue incurring charges until terminated (not just stopped) for EBS-backed instances. Security group rules are stateful but NACLs are not. Instance metadata service (IMDS) v1 is insecure; use IMDSv2. Spot instances can be terminated with 2 minutes notice.

Amazon EC2 launched in August 2006 as one of AWS's first services, revolutionizing cloud computing. VPC became mandatory in 2013. The service has continuously expanded instance types, from the original m1.small to hundreds of specialized types for compute, memory, GPU, and storage optimization.
