How to Create Wait Conditions in a CloudFormation Template

Wait Conditions, as the name suggests, is a tool used to control the order of creation of the AWS resources in a CloudFormation stack. It can pause the creation of a stack and wait for a signal to ensure that specific resources and configurations were properly launched before resuming the stack creation process. Use cases: For example, you want to make sure that a specific domain name is working before you can conclude that [...]

Multi-Account Multi-Region Data Aggregation On AWS Config

AWS Config is a service that tracks changes made to resources associated with an AWS account. This service can give you a detailed view of the resource configuration’s timeline so you can go back in time and identify when and what resource the change was made into. It also enables you to determine the overall compliance against the rules and configurations specified in your guidelines. This simplifies compliance auditing, security analysis, change management, and [...]

Specifying Triggers for AWS Config Rules

AWS Config allows you to set “rules” to evaluate configuration settings on your AWS resources. The result of these rule evaluations are then displayed on the AWS Config web console. You can control the frequency of rule evaluations by AWS Config by specifying a trigger. A trigger refers to the method of evaluation for your config rules. There are two types of triggers to select from when creating a rule. 1. Configuration Changes When [...]
