The first time I decomposed a monolith into microservices, I made every mistake in the book. We ended up with a distributed monolith—all the complexity of microservices with none of the benefits. That painful experience taught me that microservices architecture isn’t about the services themselves; it’s about the patterns that make them work together. Microservices… Continue reading
Category: Design Patterns
Design Patterns: Elements of Reusable Object-Oriented Software is a software engineering book describing recurring solutions to common problems in software design. The book’s authors are Erich Gamma, Richard Helm, Ralph Johnson and John Vlissides with a foreword by Grady Booch. The authors are often referred to as the Gang of Four, or GoF. The book is divided into two parts, with the first two chapters exploring the capabilities and pitfalls of object-oriented programming, and the remaining chapters describing 23 classic software design patterns. The book includes examples in C++ and Smalltalk.
The original publication date of the book was October 21, 1994 with a 1995 copyright, and as of July 2010, the book was in its 38th printing. The book was first made available to the public at OOPSLA meeting held in Portland, Oregon, in October 1994. It has been highly influential to the field of software engineering and is regarded as an important source for object-oriented design theory and…
The Architecture Decision That Will Make or Break Your System: Monolith vs Microservices in 2025
The debate between monolithic and microservices architectures has evolved significantly over the past decade. What was once a straightforward “microservices are better” narrative has matured into a nuanced understanding that the right architecture depends entirely on context. After leading architecture decisions across dozens of enterprise systems, I’ve learned that the most expensive mistakes come not… Continue reading
Back to Basics : Singleton Design Pattern using System.Lazy type
This article takes you to a simpler/alternative approach in making a Singleton Design Pattern implementation using System.Lazy class rather that using our traditional approach. Singleton Design Pattern implementation without lazy initialization: This code is thread safe enabled [code language=”csharp” padlinenumbers=”true”] /// <summary> /// Singleton class /// </summary> public class AppConfig { private AppConfig() { }… Continue reading
Static vs Singleton Classes
Recently while I was attending an interview I came across a question Static vs Singleton. Though I know the differences I couldn’t answer it properly, as I was not refreshed my programming knowledge before the interview. I would like to quote a reference to Jalpesh’s blog article (www.dotnetjalps.com) explaining the difference: Difference between Static and… Continue reading
