This chapter focuses on Lambda-specific topics in application design. There are many important considerations for serverless architects when designing applications for busy production systems.

This whitepaper includes the most popular architecture patterns that leverage AWS Lambda-based logic tiers: Mobile backend - A mobile application communicates with API Gateway and Lambda to access application data.

Use the AWS Architecture Icons to create architecture diagrams that communicate your design, deployment, and topology.

Feb 28, 2023 · If you’re looking to implement a custom JWT token authorizer for your AWS serverless application, this post will walk you through the process.

Nov 17, 2024 · In this article, we’ll explore the architecture behind AWS Lambda, breaking down how it manages instances, provisions resources, and handles execution in a truly serverless manner.

May 5, 2022 · The diagram below shows how the TOKEN-based Lambda authorizer in this solution works. When a request comes into API Gateway, the service will invoke the Lambda authorizer. The authorizer function code investigates if the value of the header is correct.

Architectures that use Lambda functions are designed to reduce wasted capacity. Lambda can be described as a type of serverless Function-as-a-Service (FaaS).

Choose the right database for your use case and access patterns. Build architectures that help you respond to the changing needs of your workforce. Learn to connect devices and collect, store, and analyze device data. Build effective and efficient machine learning (ML) architectures.

This whitepaper illustrates how innovations from Amazon Web Services (AWS) can be used to change the way you design multi-tier architectures and implement popular patterns such as microservices, mobile backends, and single-page applications.

These patterns can be combined to build larger architectures. A custom authorizer Lambda is a function that validates a header from the requests. Usually, this header name is Authorization and the value is a Json Web Token which is signed and expires after a certain time.
