Getting Started with Auto Scaling
There are several ways to get started with Auto Scaling. You can set up Auto Scaling through the AWS Management Console, with the AWS Command Line Interfaces (CLI), or with AWS SDKs. To learn more, see below for tutorials, blogs and videos.
Getting Started with the AWS Management Console
1
Step 1: Sign into the AWS Management Console
Create an account and sign into the console. With Amazon EC2, you pay only for what you use. If you are a new AWS customer, you can get started with Amazon EC2 for free. For more information, see
AWS Free Tier.

Step 2: Create a launch template
In the
Amazon EC2 Dashboard, choose "Launch Templates" to create a launch template, specifying a name, AMI, instance type, and other details. Below are some guidelines on setting up your first launch template.
Choose an Amazon Machine Image (AMI): We recommend the Amazon Linux 2 AMI (free-tier eligible).
Choose an instance type: We recommend the t2.micro (free-tier eligible).
Security group: You have the option to configure your virtual firewall.

Step 3: Create an Auto Scaling group
Using the Auto Scaling wizard, create an Auto Scaling group specifying a name, size, and network for your Auto Scaling group.

Step 4: Add Elastic Load Balancers (Optional)
When you set up Auto Scaling with
Elastic Load Balancing, you can automatically distribute incoming application traffic across Amazon EC2 instances within your Auto Scaling groups to build highly available, fault-tolerant applications.
Associate your load balancer with your Auto Scaling group to distribute traffic for your application across a fleet of EC2 instances that can scale with demand.
You must first create a load balancer.

Step 5: Configure Scaling Policies (Optional)
Configure scaling policies for your Auto Scaling group.
Getting Started with the AWS Command Line Tools (CLI)
You can access the features of Amazon Auto Scaling using the AWS CLI, which provides commands for a broad set of AWS products, including Amazon EC2 and Amazon CloudWatch. For more information about the commands for Auto Scaling, see the
Auto Scaling section of the AWS Command Line Interface Reference.
Getting Started with the AWS SDKs
Get started with Auto Scaling by using APIs tailored to your programming language or platform, or AWS Mobile SDK to help you build high-quality mobile apps quickly and easily. See
Tools for Amazon Web Services for more information.
