Deploy serverless functions on AWS Lambda using Terraform. Configure API Gateway integration, CloudWatch logging, environment variables, and IAM roles. Package Python or Node.js handlers with dependencies, set up event triggers, and manage function ve

When clients upload files directly to S3, your API avoids handling large payloads and you get better scalability. I generate a presigned PUT URL with a short expiry and a constrained object key prefix so users can’t overwrite arbitrary objects. The cr

Terraform provisions managed database services declaratively. AWS RDS supports PostgreSQL, MySQL, and other engines with aws_db_instance. The engine_version pins database versions. instance_class sets compute size. allocated_storage and max_allocated_

Build production-ready AWS VPC infrastructure using Terraform. Create public and private subnets across availability zones, configure NAT gateways, internet gateways, and route tables. Implement network ACLs and VPC flow logs for security and observab
