Scope of Work

Deploy a simple python application to AWS that responds to HTTP POST requests and returns a JSON response. All resources need to be provisioned using Terraform and state managed through Terraform Cloud.

High level objectives:

• Configure a pipeline in Github actions and deploy the packaged python code. (CircleCi can be used if Github actions is not preferred)
• Authenticate with AWS (Applicants choice)
• Review and deploy the Terraform configuration to provision the required resources.
• Display proper Terraform state management through Terraform Cloud.
• Provide the API endpoint URL to the deployed application.

Prerequisites

• Credentials to sandbox AWS account will be provided to you.
• Github (or other VCS provider supported by CircleCI) account
• CircleCI account (If Github is not preferred)
• Python3 (At least version 3.10)
• Pipenv
• AWS Boto3 (at least version 1.26.0)
• AWS CLI
• Terraform (At least version 1.5.0)
• Terraform Cloud Account (TFC provide a free tier)

Deployment Success Criteria

Deployment is largely up to the applicant on how to execute this. Below are the basic rquirements:

• The fundamental requirement is to successfully complete provisioning and deployment using Terraform.
• Deployment should be achieved through a chosen pipeline, using best practices.
• Test and validate terraform configuration before applying.
• Correctly package and deploy the code to a Lambda function. The type of Lambda function is up to the applicant. (Zip archive, container, etc.)
• The function should be able to respond to HTTP POST requests and return a JSON response.
• Deployment pipeline should be able to update the Lambda function with new code changes.
