"Dushnylo" Series: Introduction and the first episode.

Lately, I've noticed a recurring and perplexing theme in numerous posts and articles. Certain tech authorities assert that some established patterns are superfluous. For instance: "The repository pattern is unnecessary; simply use the ORM directly within your business logic—no need for abstractions."

Therefore, I've chosen to initiate a new series titled “Dushnylo” (Definition: An individual who is excessively critical, focuses on minute details, and overwhelms others with arguments about why something is incorrect or flawed.)

The inaugural topic in the “Dushnylo” series: "Reduced Abstraction, Increased Direct ORM Usage in Business Logic"

Why circumventing abstractions breeds disorder:

Strong Coupling and Reduced Testability

By directly integrating an ORM into your business logic, you create a strong dependency between your business layer and the database implementation. This strategy:

Makes migrating to a different ORM or database significantly more challenging.
Makes unit testing more complex due to the difficulty in mocking the database.

Elevated Code Duplication and Increased Error Probability

Without a suitable abstraction layer (such as a repository pattern), you will find yourself duplicating the same database operations in various locations. This:

Increases the likelihood of inconsistencies and defects.
Results in greater maintenance expenses.

Breach of the Single Responsibility Principle (SRP)

Incorporating database logic directly into business logic violates SRP because:

Business services should manage business rules, not database operations.
Database logic should be contained within specific components or patterns (e.g., repositories, data mappers).

In summary:

While numerous approaches and patterns exist for structuring code, permitting database operations directly within business logic without abstraction is a guaranteed route to disarray. It will create significant problems in maintainability, testing, and future growth.

Let's create scalable, well-organized architectures—not justifications. 😉

Why Microsoft Azure Well-Architected Framework Can Improve Architecture

Small and medium-sized businesses often face a common challenge: the absence of experienced cloud engineers. Due to limited resources, teams typically choose the quickest path—getting things done in the easiest, fastest way. Unfortunately, this approach often leads to solutions that aren't secure, cost too much, and become nearly impossible to extend or manage effectively. Recognizing this critical challenge, Microsoft Azure has developed the Well-Architected Framework. This comprehensive set of guidelines and best practices helps businesses assess their existing solutions and guides them toward building robust, secure, cost-effective, and manageable cloud infrastructures from the start. The Azure Well-Architected Framework is structured around five essential pillars: Cost Optimization : Ensuring that cloud resources are used efficiently and effectively, reducing unnecessary expenses. Operational Excellence : Focusing on the ability to run and monitor systems effectively, ensuring ...

"Dushnylo" Series: Monolith First approach.

I keep hearing, “You MUST start with a monolith.” Every new project? Always? When I hear that, two thoughts immediately come to mind: 1️⃣ “It depends.” You can’t just blindly say every project must start as a monolith. 2️⃣ My inner Dushnylo whispers: “Time to make a post about this.” So, here’s my take: I disagree. Not only do I disagree, but I believe the most critical and dangerous part of system design is analyzing and understanding business needs before making architectural decisions. Why? Simple. Imagine you’re building a streaming platform that processes massive amounts of data, handles notifications, and integrates with third-party services. Does this sound like something you’d build as a pure monolith? Of course not. But I do agree on one thing—you have to start somewhere. That starting point could be a simple core application —yes, it might look like a monolith at first. But you’re not designing the entire system as a monolith. ...

First Look at Cerbos: A Solution for Dynamic Role & Permission Management

Introduce My next post is about tools for managing roles and dynamically controlling access to resources. Some business requirements demand extreme flexibility, often requiring a combination of RBAC + ABAC at the same time. From my experience, I’ve seen a lot of solutions, but most don’t cover all the key points. There are three circles that are really hard to combine: Performance, Security, and Flexibility . And when someone tries to implement all three—oh, it’s painful. But I found a technology that (almost) solves this challenge: Cerbos —a scalable, open-source authorization layer for handling roles and permissions. ( Cerbos site ) Why is it good? ✅ Centralized configuration – Everything is managed in one place. ✅ Easy integration – SDKs are available for all popular languages: 🔹 .NET, Go, Java, JS, PHP, Python, Ruby, Rust ✅ Great documentation – Clear examples and guidance. ✅ Playground for testing – No need to run an app or set up tools. Just te...
