How to Receive Alerts When Specific APIs Are Called by Using AWS CloudTrail, Amazon SNS, and AWS Lambda
Let’s face it—not all APIs were created equal. For example, you may be really interested in knowing when any of your Amazon EC2 instances are terminated (ec2:TerminateInstance), but less interested when an object is put in an Amazon S3 bucket (s3:PutObject).

How to Use Shibboleth for Single Sign-On to the AWS Management Console
Update from January 17, 2018: The techniques demonstrated in this blog post relate to traditional SAML federation for AWS. These techniques are still valid and useful. However, AWS Single Sign-On (AWS SSO) provides analogous capabilities by way of a managed service. If you are just getting started with federating access to your AWS accounts, we recommend […]
