  • aws-lambda-handler-cookbook

    This repository provides a working, deployable, open source-based, serverless service template with an AWS Lambda function and AWS CDK Python code with all the best practices and a complete CI/CD pipeline.

  • The repository: https://github.com/ran-isenberg/aws-lambda-handler-cookbook

  • cfn_nag

    Linting tool for CloudFormation templates

  • For generic CloudFormation templates, check CFN-NAG.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • pydantic

    Data validation using Python type hints

  • Schema validations logic — I use Pydantic for input validation and schema validation (boto responses, API responses, input validation, etc.) use cases. The Pydantic schema can contain type and value constraint checks or even more complicated logic with the custom validator code.

  • aws-lambda-power-tuning

    AWS Lambda Power Tuning is an open-source tool that can help you visualize and fine-tune the memory/power configuration of Lambda functions. It runs in your own AWS account - powered by AWS Step Functions - and it supports three optimization strategies: cost, speed, and balanced.

  • Utilizing tools such as AWS X-Ray, AWS Lambda Power Tuning, and AWS Lambda Powertools tracer utility is recommended. Read more about it here.

  • boto3

    AWS SDK for Python

  • Schema validations logic — I use Pydantic for input validation and schema validation (boto responses, API responses, input validation, etc.) use cases. The Pydantic schema can contain type and value constraint checks or even more complicated logic with the custom validator code.

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
