Ssm Cache Python

Abstract

1. Introduction

AWS System Manager Parameter Store Caching Client for Python

This module wraps the AWS Parameter Store and adds a caching and grouping layer with max-age invalidation.

The library is split into focused modules — import from the top-level ssm_cache package for everyday use, or from a specific submodule when you need internals (e.g. for testing or extension).

2. Objective

AWS System Manager Parameter Store caching client for Python

This project demonstrates how Python, AWS, AWS Lambda can be applied to a real-world Blockchain & Cloud Computing problem.

4. Technology Stack

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

• Python 3.8 or later
• pip / virtualenv for dependencies
• VS Code, PyCharm or Jupyter Notebook
• Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/alexcasalboni/ssm-cache-python.git
cd ssm-cache-python

pip install ssm-cache

pip install "ssm-cache[dev]"
# or, from a local clone:
pip install -e ".[dev]"

from ssm_cache import SSMParameter, SecretsManagerParameter

param  = SSMParameter('my_param_name', max_age=300)
secret = SecretsManagerParameter('my_secret_name', max_age=300)

def lambda_handler(event, context):
    dbname   = param.value
    password = secret.value
    return f'Hello from Lambda with dbname {dbname}'

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

• Add a CI/CD pipeline with GitHub Actions
• Deploy to a public test network or cloud free tier
• Add monitoring and cost alerts

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

1. Why does this problem need a blockchain or cloud-native design?
2. Explain the smart contract / infrastructure components and how they interact.
3. How are gas costs or cloud costs kept under control?
4. How is the system secured (keys, IAM, access control)?
5. How would the solution scale to many more users?
