SKP’s Definitive Primer: Failures, Pitfalls, and Disadvantages of Microservices

Microservice adoption has almost become the norm in most software product and IT services organizations.

Below, I take the opportunity to make you aware of real-world issues faced by organizations of all sizes in migrating or adopting microservices.

Since learning from others’ mistakes and knowing pitfalls upfront can be helpful in preparing and planning better, this overview will be of help to those planning a shift to a microservices strategy.

Gang of Four Design Patterns Using Core Java – Part 01

To understand the philosophical and historical perspective on the Gang of Four’s design patterns, I made a short, 10-minute video, which was also my PluralSight Author Audition.

I came up with my own examples to understand design patterns further. Try downloading the code and see if it helps you in comprehending the patterns in a better way.

Some brief code snippets follow each pattern so you can get quick demonstrations. Feel free to bookmark this article as a quick reference/cheat sheet for when you want to quickly review each of them.

Deep Dive Into Multi-Threading in Java

Multi-threading represents a very intriguing topic, even after years of research and development for high quality, robust, and efficient software. With equal emphasis on hardware improvements and the software that runs on it – we have newer paradigms for parallelism.

The most important yet basic concepts are the ones which I present here. I then explain the intricacies of multi-threading in the Java programming language. Some of these are newer features and supported only from the Java Platform Standard Edition 5.0. Let us start with a quick overview and understanding of the core concepts.

Evolution of Java Memory Architecture (Post Java 7.0)

Welcome to the next part of a series of articles on key concepts in Core Java and J2EE. The series revolves around memory architecture, connection and memory leaks, core Java syntax and semantics, Java Object layout/anatomy, multi-threading, asynchronous task execution, design patterns, Java agents, class loading, API design, OOPs & SOLID.

Today, we learn about the evolution of the Java Memory Architecture, post Java 7.0.

Evolution of Java Memory Architecture (Pre Java 8.0)

Welcome to a series of articles on key concepts in Core Java and J2EE. The series revolves around memory architecture, connection and memory leaks, core Java syntax and semantics, Java Object layout/anatomy, multi-threading, asynchronous task execution, design patterns, Java agents, class loading, API design, OOPs & SOLID.

In this part, we focus on the Java Memory Architecture, from before Java 8.
