Articles on serverless architecture with Lambda, API Gateway, Step Functions, and more
EFS is mounted on Lambda functions and ECS tasks to make use of a shared file system. This article introduces access point design and performance optimization.
This article explains the current values of the various serverless limits, such as Lambda's maximum execution time of 15 minutes, memory limit of 10 GB, and payload of 6 MB, and how they affect architecture design. It does so from the perspectives of multi-tenant operation and the lifecycle of the execution environment.
This article explains how Lambda manages microVMs within the default limit of 1,000 concurrent executions, the reuse strategy through the warm pool, the placement decisions of the worker manager, and the internal optimizations that lower the cold start rate.
This article clarifies the criteria for selecting between Standard workflows and Express workflows and introduces declarative error handling with Retry/Catch and large-scale parallel processing with distributed map.
Clear criteria for choosing between HTTP API and REST API, authentication patterns with Cognito and Lambda authorizers, and practical throttling design techniques.
This article covers Lambda function design, event source mapping, cold start mitigation, and Powertools usage.
This article explains the mechanism behind Lambda cold starts from the Firecracker MicroVM lifecycle perspective, and compares optimization techniques across three axes: SnapStart, Provisioned Concurrency, and function design in terms of cost and constraints.
Learn how to build serverless APIs using Amazon API Gateway and Lambda.
Learn state machine design techniques with AWS Step Functions, including visual workflows, error handling, and workflow orchestration through Lambda integration.
