EC2 (Amazon Elastic Compute Cloud)

Can’t stop and start an instance store-backed instance.

Launch methods:

• [Amazon EC2 console] Use the launch instance wizard to specify the launch parameters.
• [Amazon EC2 console] Create a launch template and launch the instance from the launch template.
• [Amazon EC2 console] Use an existing instance as the base.
• [Amazon EC2 console] Use an AMI.
• [AWS CLI] Use an AMI that you select.
• [AWS Tools for Windows PowerShell] Use an AMI that you select.
• [AWS CLI] Use EC2 Fleet to provision capacity across different EC2 instance types and Availability Zones, and across On-Demand Instance, Reserved Instance, and Spot Instance purchase models.
• [AWS CloudFormation] Use a AWS CloudFormation template to specify an instance.
• [AWS SDK] Use a language-specific AWS SDK to launch an instance.

When you launch your instance, you can launch your instance in a subnet that is associated with one of the following resources:

• An Availability Zone
• A Local Zone
• A Wavelength Zone
• An Outpost

After you launch your instance, you can connect to it and use it.

Connection Options

SSH client
EC2 Instance Connect

AWS Systems Manager Session Manager

• Session Manager is a fully managed AWS Systems Manager capability that lets you manage your Amazon EC2 instances through an interactive one-click browser-based shell or through the AWS CLI.
• You can use Session Manager to start a session with an instance in your account.
• After the session is started, you can run bash commands as you would through any other connection type.

You can use an EC2 Fleet or a Spot Fleet to launch a fleet of instances.
In a single API call, a fleet can launch multiple instance types across multiple Availability Zones, using the On-Demand Instance, Reserved Instance, and Spot Instance purchasing options together.

An EC2 Fleet contains the configuration information to launch a fleet—or group—of instances.

• Define separate On-Demand and Spot capacity targets and the maximum amount you’re willing to pay per hour.
• Specify the instance types that work best for your applications.
• Specify how Amazon EC2 should distribute your fleet capacity within each purchasing option.

Amazon EC2 Instance Connect enables system administrators to publish one-time use SSH public keys to EC2, providing users a simple and secure way to connect to their instances.

• Pushes an SSH public key to the specified EC2 instance. The key remains for 60 seconds, which gives you 60 seconds to establish a serial console connection to the instance using SSH.
