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

**Serverless architecture** is a design pattern in which applications are built using cloud-based services that abstract away the underlying infrastructure. It's intended to make it easier and more cost-effective to build and deploy applications by eliminating the need to provision and maintain servers.

# Characteristics of serverless architecture

Here are some of the key characteristics and components of serverless architecture:

+ **Cloud functions:** These are the core building blocks of a serverless architecture. They are small, self-contained pieces of code that are executed in response to an event or trigger. Cloud functions are typically stateless, which means that they don't retain any information between invocations. This makes them easy to scale and deploy. Cloud functions can be written in a variety of languages and can be triggered by external applications or services or by the cloud platform itself.

+ **Event-driven triggers:** Serverless architectures are often event-driven, which means they are designed to respond to specific events or triggers. These triggers can be generated by external applications or services, or they can be generated by the cloud platform itself. For example, a cloud function might be triggered by an HTTP request, a change in a database, or a message published to a messaging service.

+ **Pay-per-use pricing:** Serverless architectures are typically priced on a pay-per-use basis, which means that the user only pays for the resources consumed when the cloud functions are executed. This can be more cost-effective than paying for resources up front, especially for applications that have unpredictable or variable workloads.

+ **Automatic scaling:** Serverless architectures are designed to automatically scale up or down based on the workload, which means that the user doesn't need to worry about provisioning or managing servers. The cloud platform handles the underlying infrastructure and automatically allocates resources as needed.

+ **Integration with other services:** Serverless architectures often rely on other cloud-based services to provide additional functionality or connect the application to external systems. These services can include databases, messaging services, file storage, and more.
