This pattern demonstrates how to integrate a REST API Gateway with a private Application Load Balancer and ECS Fargate cluster using VPC Link V2. Key features: - REST API Gateway with proxy integration - VPC Link V2 for private integration - Private ALB routing to ECS Fargate - Security groups and IAM roles - Uses existing VPC and subnets

@agawanea This PR mentions the SAM implementation, but I also see a TF directory included. Which one is correct? |
The Terraform implementation is in a separate branch/PR. This branch should only contain the SAM implementation of the apigw-rest-vpclink-pvt-alb pattern.

Removed the terraform pattern. This PR is only for SAM pattern. Terraform is in different PR |

Thanks. I started testing the SAM template and am encountering this error: As I looked through the template, the APIGW resource isn't a "SAM" APIGW resource, it is a standard CloudFormation resource. Is there a chance to convert the APIGW resource to AWS::Serverless::API and define the API with an OpenAPI spec file? |
- Replace CloudFormation API Gateway resources with AWS::Serverless::Api - Add external OpenAPI definition file (api.yaml) with AWS::Include transform - Add integrationTarget parameter for VPC Link V2 to ALB integration - Update README to document SAM resource usage and OpenAPI file - Update testing instructions with correct path examples - Update copyright year to 2025 - Tested and validated: API Gateway -> VPC Link V2 -> Internal ALB -> ECS working correctly

Added the SAM resource and tested it to be working fine now |
- Use full AWS service names throughout (Amazon API Gateway, Amazon VPC Link V2, Amazon Application Load Balancer, Amazon ECS) - Add problem statement explaining VPC Link V2 eliminates NLB requirement - Add --capabilities CAPABILITY_NAMED_IAM flag to deployment command - Simplify outputs to only include REST API endpoint URL - Update copyright year to 2026
