AWS Lambda & API Gateway Training Course

Master identity and access management in AWS by exploring IAM users, groups, roles, and inbuilt and custom policies, and learn to configure permissions for Lambda and S3 via the CLI.

Refresh S3 basics by guiding bucket creation, object uploads, storage classes, and public access setup, with notes on bucket policies and region considerations for Lambda and API Gateway.

Connects S3 bucket events to Lambda functions to process new objects. Learn to configure events, update execution roles, and view results in CloudWatch.

Explore DynamoDB, a fully managed NoSQL database, by creating tables, adding items, and using partition and sort keys. Learn about read/write capacity, auto scaling, and encryption.

Demonstrates creating a DynamoDB table, adding items, and reading data with a Lambda using the DynamoDB document client via a partition key; includes role configuration and testing.

Write data to a DynamoDB table using an AWS Lambda function with the put method, taking id and name from event data to create a new item.

Learn to build serverless apps on AWS with the service application model, using the SAM template and CLI to package and deploy a Lambda function via CloudFormation.

Explore using environment variables in AWS Lambda to pass values like IT and name to your function, and see how these variables update data in DynamoDB.

Explore AWS Lambda versioning and aliases, publishing versions you can't edit, using aliases to route calls to specific versions, and managing development and production stages through the console.

Learn to instrument AWS Lambda with AWS X-Ray to generate service maps and traces, measure initialization and invocation times, and visualize calls to S3, DynamoDB, or a relational database.

Explore the AWS serverless application model to build, package, and deploy SAM-based service applications for AWS Lambda using a SAM template, SAM CLI, and CloudFormation.

Learn how to include external modules in AWS Lambda by packaging dependencies locally with npm install, then zipping and uploading to Lambda, and testing your function.

Configure a Lambda to access an RDS instance in a VPC with an IAM role and Python to create a table and insert data, testing public and VPC access.

Explore how the AWS API Gateway serves REST and WebSocket APIs, enabling scalable, secure publishing and caching. Design resources and methods and connect to Lambda.

Explore creating your first API in AWS API Gateway by selecting REST or WebSocket, configuring endpoint types (regional, private), defining resources and methods, testing with postman, and deploying to stages.

Define a simple AWS Lambda function and integrate it with API Gateway to read data from DynamoDB and return it through the API Gateway, with CloudWatch logs for debugging.

Pass query string parameters from the API gateway to a lambda function using lambda proxy integration. Read them from the event object and retrieve the DynamoDB item by ID.

Implement a post method in api gateway with lambda proxy integration to add items to dynamo db by sending id and name in the request body, and validate with tests.

Explore API gateway configuration options—caching, throttling, security (web application firewall, client certs), logs, tracing, stage variables, SDK generation, and exporting to Swagger or OpenAPI 3, plus deployment history and metrics.

Learn to test AWS API Gateway endpoints using Postman, invoking GET and POST methods backed by Lambda, deploying changes, and validating queries, bodies, and headers for external testing.

Secure your api gateway with api keys and lambda authorizers by configuring usage plans, throttling, quotas, and deploying changes; require x-api-key for access.

Implement a lambda authorizer for API Gateway using custom token-based authorization, returning a policy document to authorize access, and connect it to a destination lambda.

Use API gateway to call SNS via AWS service integration, create an IAM policy and role, and implement a get method to list SNS topics.

Demonstrate building a simple web app with api gateway, lambda, and dynamodb to fetch course data and display it on a dynamic page, with cors enabled and post testing.
