In today's fast-paced digital world, cloud computing has revolutionized how data is stored, processed, and accessed. Whether you're using Google Drive, Dropbox, or running applications on AWS, cloud computing plays a crucial role behind the scenes.

This article explores cloud computing architecture with a clear breakdown of its components and how it connects users to powerful remote resources via the Internet.

 

☁️ What Is Cloud Computing?

Cloud computing is the delivery of computing services, including servers, storage, databases, networking, software, and analytics, over the Internet (the "cloud") to offer faster innovation, flexible resources, and economies of scale.

 


🧱 Components of Cloud Computing Architecture

The architecture of cloud computing involves front-end platforms, back-end platforms, cloud-based delivery, and a network (Internet). The diagram below (from the image) visually illustrates this:
