Infrastructure as Code Building Blocks for Amazon Web Services

This repository contains AWS® CloudFormation templates used by multiple MathWorks Reference Architectures for Amazon Web Services®.

Each template configures a specific chunk of infrastructure. MathWorks® reference architectures use a selection of the available templates to create their overall infrastructure by using nested stacks. Learn more about using nested stacks in the AWS documentation.

Available Templates

Name Description
security-group Creates a security group to control the inbound and outbound traffic for the resources deployed in AWS.
log-location Creates a CloudWatch log group to store log events from AWS services.
storage-location Creates an Amazon S3™ Bucket to store objects in AWS.

Usage

The CloudFormation templates in this repository are automatically published to the following Amazon S3™ bucket:

s3://mathworks-reference-architectures-templates/

Templates in this bucket are publicly accessible. The MathWorks reference architectures directly reference these templates in AWS::CloudFormation::Stack resources. For more information about this type of resource, refer to the AWS documentation.

Example

The following code shows you how to create a nested stack based on the security group template.

The AWS::CloudFormation::Stack resource declares the nested stack.

  • The TemplateURL property defines the template to use. Set it to the Amazon S3 bucket URL of the security group template version v1.0.0.
  • The Parameters property defines the inputs to the nested stack. Set the parameters VpcId and CidrIp to the values of the root stack. Add subsequent parameters to explicitly allow SSH, NICE DCV, and MATLAB Job Scheduler access but deny RDP access. Leave other parameters at their default values.

The GetAtt function retrieves an output value from the nested stack to the root stack.
