Delve into software architecture, exploring key principles, patterns, and quality attributes. Gain insights with case studies and projects, enhancing your practical skills in system design and optimization.

Software Architecture in Applications-01.png

This course offers a deep dive into the world of software architecture. It’s designed to equip software developers and architects with the knowledge and skills necessary to create, evaluate, and optimize software systems. The course covers a range of critical topics to ensure a strong foundation in architectural principles and strategies.

You will start by exploring architectural concepts and the relationship between quality attributes, requirements, and architectural styles. You’ll also examine different architectural patterns and strategies, including centralized and decentralized architecture, layered pattern, broker pattern, and microservices. Then, you’ll go into the details of important quality attributes needed while developing an architecture.

The course is equipped with multiple case studies and two projects to further enhance learning. These real-world scenarios and hands-on projects are strategically incorporated to give learners practical insights.

Software Architecture in Applications

# Overview

User expectations and demands for contemporary online apps are higher than ever. Modern applications are expected to be available 24 hours a day, from anywhere on the planet, and to operate on almost every device or screen size. Web applications must be adaptable, secure, and scalable to accommodate increased demand. Powerful user experience (UX) built on the client utilizing JavaScript and by efficiently integrating with web APIs should progressively handle complex scenarios.

There are three main characteristics of web applications, which are discussed below:


# Cloud hosting

Applications that have been converted and optimized to run seamlessly in cloud settings are critical to ensuring dependable and robust operations. The capacity to grow in response to demand can assist small firms and start-ups in keeping up with an ever-changing business environment.

**App resilience** refers to an app's capacity to continue operations at a given level despite component or operating cycle failure. The robustness of an app can improve the UX. After a system breakdown or outage, a resilient app can return to the same visual window with all of its data intact and unaltered. Elements such as corporate aims and expectations, as well as user profiles, define the amount of resilience necessary in an app.

# Cross-platform usability

One of the key features of modern web applications is cross-platform compatibility. As the name suggests, cross-platform compatible apps are platform-independent. 

If we want to develop an application, we need to pick a technology first. For example, we need to know if we're going to build an application for Android, iOS, Windows, etc. We can use Java or Kotlin for Android apps, Swift for iOS apps, and C# for Windows apps. However, the problem is, when we use this approach, we'll be using different programming languages for the same application. This might lead to compromising the UX because different platforms might have different user interface (UI) elements that could cause app consistency issues.
