aws-serverless

To build a production-ready AWS serverless API, you scaffold Lambda functions integrated with API Gateway and DynamoDB, then package and deploy the infrastructure using SAM or CDK templates for scalable, cost-efficient HTTP event processing.

Deploying serverless microservices with AWS SAM or CDK involves defining infrastructure as code templates that package Lambda functions, configure IAM permissions, and provision managed services like DynamoDB and SQS/SNS for automated, repeatable deployments.

Event-driven workflows with SQS, SNS, and Lambda are set up by configuring messaging services to trigger functions asynchronously, enabling decoupled microservices that scale automatically based on event volume while optimizing for cold starts.

Yes, this serverless approach supports projects ranging from rapid proof-of-concept to production-grade deployments by applying consistent best practices, IAM permissions, and SAM/CDK packaging configurations that ensure scalable and cost-efficient operation.

Lambda cold starts occur during function initialization and can be optimized by carefully packaging deployment artifacts with SAM or CDK, applying serverless architecture patterns, and configuring efficient function scaffolding for event-driven workflows.

Effective IAM permissions configuration is required for serverless applications, but SAM and CDK templates help manage these permissions as infrastructure as code, ensuring secure access to managed services like DynamoDB, SQS, and SNS during automated deployments.
