The Client-server model is a distributed application structure that partitions tasks or workloads between the providers of a resource or service, called servers, and service requesters called clients. In the client-server architecture, when the client computer sends a request for data to the server through the internet, the server accepts the requested process and delivers the data packets requested back to the client. Clients do not share any of their resources. Examples of the Client-Server Model are Email, World Wide Web, etc....

Ever wondered, how big applications like Amazon, Netflix, etc. never face any major faults and are always up and running? Is it possible for such big and complex pieces of code to always be error and exceptions free? Well, that’s very hard to believe, right? But the answer is NO. They do face faults but are always running and serving millions of users without the services getting down. And that’s where Microservices come to play....
The purpose of the Design phase in the Software Development Life Cycle is to produce a solution to a problem given in the SRS(Software Requirement Specification) document. The output of the design phase is a Software Design Document (SDD)....
Memento Method is a Behavioral Design pattern which provides the ability to restore an object to its previous state. Without revealing the details of concrete implementations, it allows you to save and restore the previous version of the object. It tries not to disturb the encapsulation of the code and allows you to capture and externalize an object’s internal state....
Patterns and Frameworks in Object-Oriented Analysis and Design (OOAD) are like building blocks for making strong and reliable software. This article delves at, exploring important patterns and frameworks that help make software development easier and faster. We talk about both the classic design patterns and newer frameworks that help organize software better. Understanding these patterns and frameworks helps developers create software that can handle complexity, predict problems, and last a long time without getting outdated....
An API Gateway is a key component in system design, particularly in microservices architectures and modern web applications. It serves as a centralized entry point for managing and routing requests from clients to the appropriate microservices or backend services within a system....
System design is a complicated system that involves developing efficient and scalable solutions to satisfy the demands of modern applications. One crucial thing of system design is indexing, a way used to optimize information retrieval operations. In this article, we will delve into the idea of indexing, its significance, numerous types, and best practices for implementing indexing in system layout....
Many software professionals think that architectural styles and patterns are the same. Sadly, some of the software developers don’t understand the difference between architectural patterns and design patterns. In this article, we’re going to summarize the differences between them....
The builder pattern is defined as a creational design pattern that separates the construction of a complex object from its representation, allowing us to create different representations of an object using the same construction process. It’s beneficial when an object has many optional properties or configurations....
Abstract Factory Pattern is a creational design pattern used in object-oriented programming. It provides an interface for creating families of related or dependent objects without specifying their concrete classes. This pattern is a way to encapsulate the creation of objects and ensure that they are compatible and properly configured. In this article, we’ll look at the Abstract Factory Pattern in detail with an example...
Scalable systems are crucial for meeting growing demands. Designing them requires careful planning and an understanding of scalability principles. This article offers insights into architectural patterns, operational best practices, real-world examples, and challenges. Whether you’re a developer or IT professional, this article provides you with the knowledge to build systems that can grow with your business needs...
