Monolithic Structure With Independent Projects: Solution

Hey guys! Let's talk about a common issue in software development: the monolithic structure with independent projects. It's like having four separate apartments in one giant building – they're all under the same roof, but they function independently. This setup, while seemingly convenient at first, can lead to some serious headaches down the road. In this article, we'll dissect this issue, understand why it's problematic, and explore the best way to untangle this web.

Understanding the Problem: The Accidental Monorepo

At its core, the issue we're tackling is what's often referred to as an "accidental monorepo." Imagine a scenario where you have a single repository housing multiple distinct projects, each with its own configuration, dependencies, and even its own README file. In our case, we're looking at a repository containing docker-csv, docker-sql, docker-influx-grafana-nodered-py, and reto0. Each of these is a self-contained application or component. But why is this a problem, you ask? Let's break it down.

1. The Intertwined Lifecycles: A Versioning Nightmare

One of the biggest challenges with this structure is the coupling of lifecycles. Think of it this way: if you make a change in the docker-csv project, you're committing it to the same history as a change in the reto0 documentation, even if they're completely unrelated. This creates a versioning headache. You lose the ability to version each project independently. It becomes nearly impossible to accurately track changes and manage releases. Semantic versioning goes out the window, and you're left with a tangled mess.

2. Developer Confusion: What's the Real Purpose?

For any new developer joining the team, this structure can be incredibly confusing. What's the main purpose of the reto0-pia-g1 repository? How do these seemingly disparate components connect? It's like walking into a room with four doors, each leading to a completely different place, and no map to guide you. This lack of clarity can significantly slow down onboarding and development velocity.

3. The Versioning Conundrum: One Size Doesn't Fit All

Imagine needing to release a new version of your docker-csv project (say, v1.0) while the docker-sql project is still at v1.2. In a monolithic structure, this becomes a logistical nightmare. You can't independently version each project. This inflexibility can stifle innovation and make it difficult to respond to specific needs or bug fixes within individual projects. It’s akin to trying to fit a square peg in a round hole – it just doesn’t work.

4. Identifying the Culprit: The Directory Structure

Let’s visualize what we're dealing with. The root directory contains four subprojects, each a potential candidate for independent existence:

reto0-pia-g1/
├── docker-csv/ # Project 1
├── docker-sql/ # Project 2
├── docker-influx-grafana-nodered-py/ # Project 3
└── reto0/ # Project 4 (Documentation)

Each of these directories represents a separate entity that could, and arguably should, live in its own repository.

The Solution: Divide and Conquer – Embracing Microservices Principles

So, what's the antidote to this monolithic mayhem? The primary recommendation is to divide and conquer. We need to break this monorepo into smaller, more focused repositories. Each top-level directory should become its own Git repository. This aligns with the best practices of microservices and modular software development.

Why This Works: The Benefits of Separation

Separating the projects into individual repositories brings a multitude of benefits:

• Independent Management: Each project can be managed, versioned, and deployed independently.
• Clearer Purpose: Each repository has a clear and distinct purpose, making it easier for developers to understand and contribute.
• Simplified Versioning: You can version each project independently, allowing for more granular control and faster releases.
• Enhanced Collaboration: Teams can focus on specific projects without being bogged down by the complexity of a large, monolithic codebase.
• Improved Scalability: Each project can be scaled independently, allowing you to optimize resources and performance.

The Action Plan: Creating Independent Repositories

Let’s get down to the nitty-gritty. Here’s a concrete example of how we can break down our monolithic structure:

We should create the following separate repositories, migrating the content from each corresponding directory:

1. csv-data-service Repository

• Content: The contents of the docker-csv directory.
• Purpose: A microservice dedicated to processing CSV data. This will be its sole focus, making development and maintenance much cleaner.

2. sql-data-service Repository

• Content: The contents of the docker-sql directory.
• Purpose: A microservice designed to interact with a SQL database. By isolating this functionality, we make it easier to manage database interactions and scale them independently.

3. monitoring-stack Repository

• Content: The contents of the docker-influx-grafana-nodered-py directory.
• Purpose: A pre-configured monitoring and visualization stack. This repository will provide a centralized location for all monitoring-related configurations and tools, simplifying system observability.

4. project-documentation Repository

• Content: The contents of the reto0 directory.
• Purpose: The general documentation for the project or organization. Housing documentation in its own repository ensures that it can be updated and versioned independently of the codebase, keeping it current and accessible.

The Bigger Picture: Aligning with Best Practices

This separation isn't just about tidying up the codebase; it's about aligning with best practices in microservices architecture and modular software development. Each component gains independence in management, versioning, and deployment. This modularity enables teams to work autonomously, fostering faster development cycles and more resilient systems. It’s about setting up a development environment that’s scalable, maintainable, and a joy to work in.

Key Benefits Revisited: Why This Matters

Let’s hammer home why this approach is so crucial. By embracing separate repositories, we unlock the following key benefits:

• Independent Deployment: Deploy updates to one service without affecting others. This is huge for continuous delivery.
• Independent Scaling: Scale services based on their specific needs. No more one-size-fits-all scaling strategies.
• Independent Versioning: Each service gets its own versioning scheme. Semantic versioning becomes your best friend.
• Improved Team Autonomy: Teams can own and manage their services end-to-end.
• Reduced Cognitive Load: Smaller codebases are easier to understand and maintain. Developers can focus on what matters.

Conclusion: Embracing Modularity for Long-Term Success

In conclusion, dealing with a monolithic structure housing independent projects can feel like trying to navigate a maze blindfolded. The intertwined lifecycles, developer confusion, and versioning challenges can significantly hinder your team's productivity and your project's success. However, by embracing the principle of divide and conquer and breaking down the monorepo into smaller, focused repositories, you can unlock a world of benefits. You'll gain independent management, versioning, and deployment capabilities, paving the way for a more scalable, maintainable, and efficient development environment. So, guys, let's embrace modularity and build software that's not just functional, but also a pleasure to work with! It's about making life easier for everyone involved and setting your project up for long-term success. And remember, a well-structured project is a happy project!
