Developing Serverless Solutions on AWS

Developing Serverless Solutions on AWS

This course gives developers exposure to and practice with best practices for building serverless applications using AWS Lambda and other services in the AWS serverless platform. You will use AWS frameworks to deploy a serverless application in hands-on labs that progress from simpler to more complex topics. You will use AWS documentation throughout the course to develop authentic methods for learning and problem-solving beyond the classroom.

Course level: Intermediate

Objetivos

In this course, you will learn to:

Apply event-driven best practices to a serverless application design using appropriate AWS services
Identify the challenges and trade-offs of transitioning to serverless development, and make recommendations that suit your development organization and environment
Build serverless applications using patterns that connect AWS managed services together, and account for service characteristics, including service quotas, available integrations, invocation model, error handling, and event source payload
Compare and contrast available options for writing infrastructure as code, including AWS CloudFormation, AWS Amplify, AWS Serverless Application Model (AWS SAM), and AWS Cloud Development Kit (AWS CDK)
Apply best practices to writing Lambda functions inclusive of error handling, logging, environment re-use, using layers, statelessness, idempotency, and configuring concurrency and memory
Apply best practices for building observability and monitoring into your serverless application
Apply security best practices to serverless applications
Identify key scaling considerations in a serverless application, and match each consideration to the methods, tools, or best practices to manage it
Use AWS SAM, AWS CDK, and AWS developer tools to configure a CI/CD workflow, and automate deployment of a serverless application
Create and actively maintain a list of serverless resources that will assist in your ongoing serverless development and engagement with the serverless community
