Dear AWS Customer,
We are pleased to announce that it's now even easier to use Auto Scaling to
manage your Amazon EC2 capacity and maintain availability of your
applications. Starting today, you can use the AWS Management Console to
create and update Auto Scaling groups and launch configurations.
To get started, log in to the Amazon EC2 console and choose "Auto Scaling
Groups" in the panel at the left, or click here.
In the console, you can create an Auto Scaling group based on a template that
you define for your instances. You specify the number of instances you want
to run and Auto Scaling will launch the instances for you, keeping them
balanced across Availability Zones and replacing unhealthy ones.
You can also create scaling policies that adjust your group size dynamically
in response to Amazon CloudWatch metrics, such as average CPU utilization.
Even if your application only requires a single instance, using Auto Scaling
can help you keep it available by replacing the instance if it fails status
checks.
For more information, see Get Started with Auto Scaling Using the Console in
the Auto Scaling Developer Guide.
Sincerely,
The Amazon EC2 team
