An Overview of Cloud Computing: Why It's So Popular

Introduction

Cloud computing has evolved from being an innovative technology to a core technology of today’s business and personal computing environments within the past few years. This rapid uptake and adoption of this technology across various industries points to its importance in the modern world. This blog post explains what cloud computing means and aims at identifying key aspects of cloud computing and its increasing popularity

What is Cloud Computing?

Cloud computing encompasses a range of services such as servers, storage, databases, networking, software, analytics, and intelligence. Its core objective is to facilitate faster innovation, provide flexible resources, and leverage economies of scale. Instead of investing in and managing their own computing infrastructure or data centers, businesses can rent access to various resources—from applications to storage—from a cloud service provider.This allows businesses to avoid the upfront cost and complexity of owning and maintaining IT infrastructure, and instead simply pay for what they use when they use it.

Key Components of Cloud Computing

1. Infrastructure as a Service (IaaS)

IaaS provides virtualized computing resources over the internet. It is the most basic category of cloud services. With IaaS, businesses can rent IT infrastructure such as servers and virtual machines (VMs), storage, networks, and operating systems from a cloud provider on a pay-as-you-go basis.

2. Platform as a Service (PaaS)

Platform as a Service (PaaS) delivers applications and the operating systems and development tools required for building the application, through the Internet. A key characteristic of this service model is that it permits the PaaS provider organization to host the required infrastructure components at both the hardware and software levels. Therefore, developers are freed from a need to provision and maintain own internal hardware and software infrastructure, as well as are able to concentrate on deployment of applications and services only.

3. Software as a Service (SaaS)

SaaS delivers software applications over the internet, on a subscription basis. SaaS providers host and manage the software application and underlying infrastructure, and handle any maintenance, like software upgrades and security patching.Users typically access the application via the internet using a web browser on devices such as phones, tablets, or PCs.

4. Function as a Service (FaaS)

FaaS, also known as serverless computing, allows developers to build, run, and manage application functionalities without the complexity of maintaining the infrastructure typically associated with developing and launching an app.

Why Cloud Computing is So Popular
