Editing AWS Lambda (section)

== Creating (Synthesis / Create) ==
🏗️ At this level, an expert can **design**, **compose**, and **optimize** systems using AWS Lambda.

* '''Design patterns & best practices'''
** Event-driven microservices using SNS or EventBridge.
** Reusable logic via Lambda layers.
** Idempotent execution to handle retries safely.

* '''Security & authentication patterns'''
** Principle of least privilege in IAM roles.
** Secret storage using AWS Systems Manager Parameter Store or Secrets Manager.
** VPC-integrated Lambda for private networking.

* '''Lifecycle management strategies'''
** Automated deployments with CI/CD pipelines.
** Versioning and aliasing for staged rollouts.
** Traffic shifting (blue-green or canary deployments).

* '''Scalability & optimization patterns'''
** Asynchronous processing with SQS.
** Provisioned concurrency for latency-sensitive workloads.
** Efficient packaging and dependency management.

* '''Typical creation-level abilities'''
** Can architect multi-service solutions using Lambda.
** Can design cost-efficient, scalable serverless systems.
** Can enforce security, resiliency, and maintainability.
