Lab description

Header-based routing allows you to process requests in different ways depending on the presence or value of an HTTP header. This technique is well-supported in the AWS cloud by Application Load Balancers and AWS Lambda.

Learning how to implement and debug header-based routing will make you more effective at working with complex deployments.

In this lab, you will implement header-based HTTP request routing and learn how to observe headers using Amazon CloudWatch and AWS X-Ray.

Learning objectives

Upon completion of this beginner-level lab, you will be able to:

  • Create an Application Load Balancer routing rule
  • Enable AWS X-Ray for an AWS Lambda function
  • Use Amazon CloudWatch and AWS X-Ray to view request headers

Intended audience

  • Candidates for the AWS Certified DevOps Engineer Professional certification
  • Cloud Architects
  • DevOps Engineers
  • Software Engineers

Prerequisites

Familiarity with the following will be beneficial but is not required:

  • Elastic Load Balancing (ELB)
  • AWS Lambda
  • AWS X-Ray
  • Amazon CloudWatch

The following content can be used to fulfill the prerequisites:
