 The goal of this project is to build, configure, and automate the deployment of a simple serverless application on AWS. Created a health check endpoint that logs requests and stores them in a database, with a CI/CD pipeline to manage deployments for both staging and production environments, fully provisioned via Terraform and deployed automatically using GitHub Actions.
 
+## Prerequisites
+- An AWS account and IAM user with rights to create IAM, Lambda, API Gateway, DynamoDB, CloudWatch.
+- Local toolchain:
+  - Terraform v1.2+
+- GitHub repo secrets (Repository > Settings > Secrets):
+  - `AWS_ACCESS_KEY_ID`
+  - `AWS_SECRET_ACCESS_KEY`
+  - `AWS_REGION` (e.g. `us-east-1`)

+_GitHub Action CICD_
+### Staging
+1. Push to branch `staging` (or open a PR merging into `staging` and merge).
+2. GitHub Action will automatically:
+   - `terraform init`
+   - `terraform plan -var-file="staging.tfvars"`
+   - `terraform apply` (auto-approved)
+
+### Production
+1. Push to branch `main` (or merge PR into `main`).
+2. Workflow will run and wait for **manual approval** in the `production` environment (configure environment reviewers in Settings).
+3. Approve in GitHub UI → workflow will `apply` the `prod.tfvars` plan.
+
+### Trigger Destroy CICD pipeline
+Manually trigger the terraform destroy workflow in GitHub UI -> actions -> destroy.yaml
+
+## Testing the /health endpoint
+
+After deployment, Terraform outputs the API endpoint. You can fetch it:
+- From the Actions run logs (last step runs `terraform output -json`)
+
+Example curl (replace `<API_ENDPOINT>` with the `api_endpoint` output):
 ```
-# Hello lambda function
-def lambda_handler(event, context):
-    name = event.get("name", "World")
-    message = f"Hello, {name}!"
-
-    return {
-        "statusCode": 200,
-        "body": message
-    }
-
-# Run the funtion locally for testing
-if __name__ == "__main__":
-    test_event = {"name": "Emmanuel Ogah"} 
-    result = lambda_handler(test_event, None)
-    print(result)
-```
-
-Run the python funtion locally using VS Code Run Button
-- Click the “Run Python File” button in the top right corner.
+# GET
+curl "https://nrbefv9bcj.execute-api.us-east-1.amazonaws.com/health"
 
-```
 # Output
+{"status": "healthy", "message": "Request processed and saved.", "id": "0fb4fa88-64a1-440d-84b1-5a6d4354364b"}
 
-{'statusCode': 200, 'body': 'Hello, Emmanuel Ogah!'}"
