Reading Time: 4 minutes If you want to build Microservices, You may prefer Axon, a Java-based framework. It provides utility to implement CQRS (Command Query Responsibility Segregation), Event Sourcing, and DDD (Domain Driven Design) architectural patterns while developing a software application. Axon facilitates the implementation of Command Handling, Event Routing, Event Sourcing, Snapshotting, and many more building blocks. It has very friendly APIs to use these implementations and build Continue Reading

SOLID Principles

November 9, 2021December 20, 2021application design, Architecture, JavaDesign, Design principles, solid principles

Reading Time: 5 minutes SOLID is stand for Single Responsibility Principle, Open-Closed Principle, Liskov Substitution Principle, Interface Segregation Principle, and Dependency Inversion Principle. It is refers to five design principles in object-oriented programming, designed to reduce code and improve the value, class, function, and maintainability of software. The SOLID principles help the user develop minimized coupled code. If code is tightly coupled, a group of classes are dependent on Continue Reading

Hexagonal Architecture

January 25, 2021March 4, 2021application design, Architecture, Studio-Scala#Singapore, hexagonal architecture, Knoldus Singapore, singapore, singaporetech

Reading Time: 2 minutes As the 12 factor app states, that each component of an application should work independent of each other. This is required in order to make the update process simpler. This is where many developers use architectural pattern, commonly known as hexagonal architecture. The main aim of this architecture is to divide the application into loosely couple components. These components can then be connected using ports Continue Reading

The 12 Factor App

Reading Time: 4 minutes This blog will explain the principles of the 12 factor app. These principle basically eliminate the unnecessary ache required while building your application. It makes the development process smooth, thus resulting in a robust and reliable application. 1. Codebase: A twelve-factor app states that a single app should not have multiple codebases, otherwise it is a distributed system instead of an app. Also, multiple apps Continue Reading
