What was before Microservices ??? So before digging into the Microservices Architecture, we need to understand what was before Microservices and what are problems with that architecture. So before Microservices, there was Monolithic Architecture. Monolithic Architecture is like a big container where all the software components of an application are assembled and deployed together. That…

What is JavaScript ?? JavaScript is a programming language that conforms to ECMAScript specifications. It is one of the main programming langue used all around the world. By default, JavaScript programs run using a Single Thread. Though there are ways to create new threads, JavaScript is considered a Single-Threaded language. JavaScript does not wait…

In this article, we will explore the Builder Design Pattern and the Chain of Responsibility Design Pattern. The Builder comes under the Creational Pattern, and the Chain of Responsibility comes under the Behavioural Pattern. Let’s explore more on these patterns individually. Builder Design Pattern The Builder Pattern uses the step-by-step approach in building…

What is Design Pattern ?? To achieve best practices in object-oriented programming, many developers use Design Patterns. Design Patterns are interpreted as common solutions given for most of the problems we faced in the software development process. These solutions were obtained by trial and error by numerous software developers over quite a substantial period. The…

Before talk about DNS poisoning, we will get an understanding of what DNS and how it works. Usually, as humans, we access information on websites via a domain name like google.com, youtube.com, etc. But the web browsers and the computer can’t understand these domain names as they interact with IP…

Before dive into ARP Spoofing, let understand what is ARP(Address Resolution Protocol) means. The logical address (IP address) is used by machines to send and receive messages. But the physical address (MAC address) in layer 2 of the OSI model is responsible for the actual communication to happen. So we…

In the versions before Java 8, we had Date and Calendar APIs to handle date and time. To overcome the shortcomings of the older java util Date and java util Calendar, Java 8 introduced new APIs for Date and Time. …

When we talk about the evolution of Software Architecture, it is mainly categorized as Monolithic (Standalone) Architecture, Service-Oriented Architecture, and Micro-Services Architecture. In this article, we will discuss how software architecture implementations change from Monolithic and Service-Oriented Architecture phases. 1. One-Tier Architecture 1-Tier Architecture is the simplest architecture in which the client, server…

HTTP (Hypertext Transfer Protocol) is the underline communication protocol used for the World Wide Web (invented by Tim Berners-Lee ). HTTP functions as a request-response protocol in a client-server architecture model. Internet Engineering Task Force (IETF) and World Wide Web Consortium (W3C) are responsible for the establishment of standards in…
