All About AWS Lambda and Serverless

Serverless architecture reduces operational and development costs, simplifies deployment, and lets providers handle scaling and greener computing by abstracting underlying infrastructure.

Explore a practical serverless architecture using AWS Lambda, S3 buckets, and DynamoDB; deploy code, monitor with CloudWatch, and expose secure API Gateway endpoints with throttling.

Learn how AWS S3 bucket functions as object storage, create a uniquely named bucket in a region, enable versioning and encryption, control public access, logging, and tagging for static websites.

Learn what AWS Lambda is and how to set up and deploy a serverless function with Eclipse, test a hello function, and integrate with DynamoDB while configuring IAM roles.

Unit test the uploaded lambda function on the server using Eclipse, run and verify a hello world program, and confirm deployment before proceeding to Dinamo DBE.

Learn how to integrate an AWS Lambda function with API Gateway to expose a secure, scalable serverless API, deploy it, and configure security, usage plans, and request throttling.

Explore the limitations of serverless architecture with Lambda, including restricted vendor control, limited language options, variable execution duration and cold start latency, and challenges in debugging and observability.

Set up a parallel, updated environment, test it internally, and switch traffic from the old to the new stack via the load balancer to achieve zero downtime.
