    • Fault-tolerant design patterns (for example, retries with exponential backoff and jitter, dead-letter queues)
    • Differences between synchronous and asynchronous patterns
    • Creating fault-tolerant and resilient applications in a programming language (for example, Java, C#, Python, JavaScript, TypeScript, Go)
    • Creating, extending, and maintaining APIs (for example, response/request transformations, enforcing validation rules, overriding status codes)
    • Writing and running unit tests in development environments (for example, using AWS Serverless Application Model [AWS SAM])
    • Writing code to use messaging services
    • Writing code that interacts with AWS services by using APIs and AWS SDKs
    • Handling data streaming by using AWS services
  2. 1.2Develop code for AWS Lambda
    • Event source mapping
    • Stateless applications
    • Unit testing
    • Event-driven architecture
    • Scalability
    • The access of private resources in VPCs from Lambda code
    • Configuring Lambda functions by defining environment variables and parameters (for example, memory, concurrency, timeout, runtime, handler, layers, extensions, triggers, destinations)
    • Handling the event lifecycle and errors by using code (for example, Lambda Destinations, dead-letter queues)
    • Writing and running test code by using AWS services and tools
    • Integrating Lambda functions with AWS services
    • Tuning Lambda functions for optimal performance

    • Relational and non-relational databases
    • Create, read, update, and delete (CRUD) operations
    • High-cardinality partition keys for balanced partition access
    • Cloud storage options (for example, file, object, databases)
    • Database consistency models (for example, strongly consistent, eventually consistent)
    • Differences between query and scan operations
    • Amazon DynamoDB keys and indexing
    • Caching strategies (for example, write-through, read-through, lazy loading, TTL)
    • Amazon Simple Storage Service (Amazon S3) tiers and lifecycle management
    • Differences between ephemeral and persistent data storage patterns
    • Serializing and deserializing data to provide persistence to a data store
    • Using, managing, and maintaining data stores
    • Managing data lifecycles
    • Using data caching services
