Developing Serverless Solutions on AWS

Dieses Training vermittelt Entwicklern die besten Praktiken für die Erstellung serverloser Anwendungen mit AWS Lambda und anderen Services der AWS Serverless-Plattform. Sie verwenden AWS Frameworks zur Bereitstellung einer serverlosen Anwendung in praktischen Übungen, die von einfacheren zu komplexen Themen. Sie werden die AWS-Dokumentation während des gesamten Kurses nutzen, um authentische Methoden für und Problemlösungen über den Unterricht hinaus zu entwickeln.

In diesem Training lernen Sie:

• 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
