Amazon EC2 Auto Scaling code examples for the SDK for C++

Overview

Shows how to use the AWS SDK for C++ to create and manage Amazon EC2 Auto Scaling groups and instances.

Amazon EC2 Auto Scaling helps you maintain application availability and lets you automatically add or remove EC2 instances using scaling policies that you define.

⚠️ Important

• Running this code might result in charges to your AWS account.
• Running the tests might result in charges to your AWS account.
• We recommend that you grant your code least privilege. At most, grant only the minimum permissions required to perform the task. For more information, see Grant least privilege.
• This code is not tested in every AWS Region. For more information, see AWS Regional Services.

Code examples

Single actions

Code excerpts that show you how to call individual service functions.

• Create a group (CreateAutoScalingGroup)
• Delete a group(DeleteAutoScalingGroup)
• Disable metrics collection for a group(DisableMetricsCollection)
• Enable metrics collection for a group (EnableMetricsCollection)
• Get information about groups (DescribeAutoScalingGroups)
• Get information about instances (DescribeAutoScalingInstances)
• Get information about scaling activities (DescribeScalingActivities)
• Set the desired capacity of a group (SetDesiredCapacity)
• Terminate an instance in a group (TerminateInstanceInAutoScalingGroup)
• Update a group (UpdateAutoScalingGroup)

Scenarios

Code examples that show you how to accomplish a specific task by calling multiple functions within the same service.

• Manage groups and instances

Run the examples

Prerequisites

Before using the code examples, first complete the installation and setup steps for Getting started in the AWS SDK for C++ Developer Guide. This section covers how to get and build the SDK, and how to build your own code by using the SDK with a sample Hello World-style application.

Next, for information on code example structures and how to build and run the examples, see Getting started with the AWS SDK for C++ code examples.

Tests

⚠️ Running the tests might result in charges to your AWS account.

   cd <BUILD_DIR>
   cmake <path-to-root-of-this-source-code> -DBUILD_TESTS=ON
   make
   ctest
