Cloud Native Store

Cloud Native Store is a Go-based key-value store showcasing cloud-native patterns like transactional logging, data sharding, encryption, TLS, and circuit breakers. Built with hexagonal architecture for modularity and extensibility, it includes a robust API and in-memory storage for efficiency and stability.

Project Motivation

The motivation behind Cloud Native Store is to provide a practical example of implementing a key-value store that adheres to cloud-native principles. The project aims to:

1. Demonstrate best practices for building scalable, secure, and reliable cloud-native applications.
2. Showcase the use of hexagonal architecture to enable modular and testable code.
3. Offer a reference implementation for features like encryption, transactional logging, and stability mechanisms.
4. Inspire developers to adopt cloud-native patterns in their projects.
