Course Description
This course gives developers exposure to & practices with best practices for building serverless applications using AWS Lambda & other services in the AWS serverless platform. Professionals will utilize AWS frameworks to deploy a serverless application in hands-on-labs that progress from straightforward to more complex topics. Professionals will use AWS documentation throughout the course to develop authentic methods for learning & problem-solving beyond the classroom.
Prerequisites
We recommend that attendees of this course have-

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

FAQs
Serverless computing offers a number of advantages over traditional cloud-based or server-centric infrastructure. For many developers, serverless architectures offer greater scalability, more flexibility, & quicker time to release, all at a reduced cost.
Serverless applications start with AWS Lambda, an event-driven compute service natively integrated with over 200 AWS services & software as a service (SaaS) application.
There are three methods of data storage, namely –
- Object storage
- File storage
- Block storage
EC2 is a service that enables business clients to run application programs in the computing environment.
AWS security provides opportunities to protect the data, check out security-related activity & receive automated responses.
