This repository is organized into multiple sub-projects, each focusing on a specific domain or technology:

• CityGenerator app

• MicroChess app

• ESP8266: A Wi-Fi microchip-based NTP server for IoT applications.

• ANN: Implementation of artificial neural networks for Arduino and ESP32 platforms.

• Blockchain: Bitcoin infrastructure and live network mapping tools.

• CNC: Desktop AppImage for CNC milling machines and 3D printers.

• HA Cluster: High Availability clusters for IT resource management.

• Gekko M4 Globular Cluster Cryptocurrency: Sustainable personal finance modeling.

This repository adopts various software architecture patterns to enhance modularity, scalability, and maintainability. Some notable patterns include:

1. Layered Architecture:
   • Projects like ANN and ESP8266 utilize layered designs, separating hardware interfacing, communication protocols, and logic layers.
2. Event-Driven Architecture:
   • The Blockchain and Gekko M4 sub-projects utilize event-driven principles to react to real-time data changes.
3. Microservices and Modular Design:
   • Projects such as HA Cluster and CNCjs are designed to function as independent modules, making them reusable and flexible.
4. Client-Server Architecture:
   • IoT-related projects like ESP8266 NTP Server implement client-server communication models.

Description:
The HA Cluster Project focuses on deploying High Availability (HA) Clusters effectively to ensure continuous availability of critical IT resources and services.

Key Features:

• High Availability: Reduces downtime by creating resilient server clusters to handle failures seamlessly.
• Scalable Architecture: Designed to scale with growing infrastructure needs.
• Fault Tolerance: Implements redundancy to protect against hardware and software failures.
• Learning Journey: Comprehensive documentation and resources to help others understand and deploy HA clusters.

Getting Started:

1. Clone the repository for the HA Cluster project:

   git clone https://github.com/universalbit-dev/HArmadillium.git
   cd HArmadillium

2. Follow the documentation to set up your HA Cluster environment.

Use Cases:

• Enterprise IT: Ensure uninterrupted access to mission-critical applications.
• Web Hosting: Maintain availability for websites and services during server failures.
• Database Clustering: High availability for databases with automatic failover.

⚠️ Note: High Availability (HA) clusters are not limited to hosting shared websites.
🖧 They provide redundancy and reliability for many types of applications—such as databases, file storage, real-time analytics, industrial automation, and more.

Why?
HA clusters are designed to ensure continuous service and minimal downtime by automatically handling failures and redistributing workloads. This makes them suitable wherever uninterrupted operation is critical, not just for web servers, but for any application where availability and fault tolerance are essential.

This repository utilizes a Shared Repository design pattern. Below is an overview of the trade-offs associated with this architectural decision:

• Efficient Data Sharing: Provides a highly efficient way to share large amounts of data across different parts of the system.
• Decoupled Logic: A subsystem does not have to worry about how data is produced or used by other subsystems.
• Centralized Management: Simplifies the administration of backups, security, access control, and error recovery in one central place.
• High Extensibility: Makes it easy to scale the ecosystem by adding new subsystems without disrupting existing ones.

• Performance Compromises: Subsystems must agree on a unified, compromise data model, which can negatively impact the performance of individual components.
• High Evolution Cost: Adopting a new data model is difficult and costly. If changes are made, the entire repository must be modified and all subsystems must be updated.
• Generic Policies: Centralizing backup and security fails to address the unique, highly specific requirements of certain subsystems.
• Scaling Bottlenecks: It is difficult to efficiently distribute the repository across multiple physical machines while keeping it logically centralized, often leading to redundancy and data consistency issues.
