Standard component cards in Application Composer

Before a standard component card is placed on Application Composer's visual canvas, it is listed as a Standard (IaC) resource card on the Resources palette in Application Composer. A standard (IaC) resource card represents a single AWS CloudFormation resource. Each standard IaC resource card, once placed on the visual canvas, becomes a card labeled Standard component, and may be combined to represent multiple AWS CloudFormation resources.

Each standard IaC resource card can be identified by its AWS CloudFormation resource type. The following is an example of a standard IaC resource card that represents an AWS::ECS::Cluster AWS CloudFormation resource type:

A standard IaC resource cluster card.

Each standard component card visualizes the AWS CloudFormation resources that it contains. The following is an example of a standard component card that includes two standard IaC resources:

A DemoLambdaFunction standard component card that includes two standard IaC resource cards.

As you configure the properties of your standard component cards, Application Composer may combine related cards together. For example, here are two standard component cards:

Two standard component cards. One is an AWS::Lambda::Function card and the other is an AWS::IAM::Role card.

In the Resource properties panel of the standard component card representing an AWS::Lambda::Function resource, we reference the AWS Identity and Access Management (IAM) role by its logical ID:

After saving our template, the two standard component cards combine into a single standard component card.
