Overview
Building on AWS gives developers access to a vast set of services to create scalable, secure, and innovative applications. However, navigating service APIs, security best practices, and deployment processes can be time-consuming. Kiro, an AI-powered code editor, addresses these challenges by embedding AWS-specific intelligence directly into the development workflow.
In this post, we’ll explore Kiro’s capabilities for AWS developers and walk through a hands-on example where we create an Amazon S3 bucket with an AWS Lambda trigger — all assisted by Kiro.
Why Kiro is Different
-Kiro is not just a code editor. It’s an AI assistant built into your development environment. For AWS developers, this means:
-Smart AWS Autocompletion — Predictive code suggestions for AWS SDKs like Boto3, AWS SDK for JavaScript, and more.
-Infrastructure as Code Generation — Create Terraform or AWS CloudFormation templates directly from plain-language comments.
Security Best Practices — Alerts for overly permissive IAM policies or insecure resource configurations.
Integrated Cloud Debugging — Stream AWS CloudWatch logs in real time without leaving the editor.
Multi-Service Orchestration — Suggest AWS architecture patterns and generate example code for them.
**
Hands-On Example:**
S3 + Lambda Workflow with Kiro
Step 1: Create a New AWS Project in Kiro
We start a Python project in Kiro. The editor detects AWS usage and recommends installing Boto3.
pip install boto3
Kiro offers to set up AWS credentials locally for development.
Step 2: Write the Upload Function
Kiro autocompletes the entire upload_to_s3 function:
import boto3
def upload_to_s3(file_name, bucket_name):
s3 = boto3.client('s3')
s3.upload_file(file_name, bucket_name, file_name)
print(f"Uploaded {file_name} to {bucket_name}")
It also suggests adding error handling.
Step 3: Generate Infrastructure as Code
We add a simple comment:
create s3 bucket with lambda trigger
Kiro generates a Terraform configuration for:
An S3 bucket
A Lambda function
An S3 event notification to trigger the Lambda
Step 4: Write the Lambda Function
Kiro provides a ready-to-use Lambda handler:
import json
def lambda_handler(event, context):
for record in event['Records']:
bucket = record['s3']['bucket']['name']
key = record['s3']['object']['key']
print(f"Processing file {key} from bucket {bucket}")
return {"statusCode": 200, "body": json.dumps("Success")}
Step 5: Deploy with Terraform
Kiro generates and runs:
terraform init
terraform apply -auto-approve
Step 6: Test and Monitor
After uploading a file with:
python upload.py
Kiro streams CloudWatch logs directly inside the editor, showing Lambda’s output in real time.

Why This Matters for AWS Developers
Kiro consolidates coding, AWS resource creation, deployment, and debugging into a single AI-assisted workflow. This results in:
Faster time to market — Build and deploy in minutes, not days.
Improved security — Avoid common misconfigurations.
Reduced context switching — No need to move between console, CLI, and docs.
Conclusion
Kiro’s deep integration with AWS workflows transforms how developers approach cloud development. By embedding AWS-specific intelligence directly into the coding process, Kiro reduces setup time, enforces best practices, and enables developers to focus on building great applications.
For teams working on AWS, Kiro is more than an editor — it’s a partner in delivering secure, scalable, and innovative solutions.
