What is cloud ft Bank

Introduction

Have you ever tried to explain a technical concept to a non technical person? As a cloud engineer,I had to.But articulating those in technical terms won’t make a change.So I had to explain it with analogies which help them to create a high level image. Cloud Snippet is a series of blog trying to solve this by comparing each concept with real-world scenarios which are applicable to a technical/non-technical person.

So let’s begin

What is cloud computing?

Real Definition

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

Breakdown

Let us consider the cloud as a bank. Earlier you might have stored your precious assets such as money, documents, etc in the home itself. At that time, bank service was introduced. Then you understood the issue with storing the assets in your home.Following are the few.

• I don’t have much space in my home to purchase a locker (Scaling)
• I need to handle the theft risk (Security)
• If I spend all my money, this reduces the requirement of a large locker. (Underutilised)
• If you are out of the station, you cannot access the assets until you are back which means no remote access. (accessibility)
• If I buy a low-quality locker, there might be a chance of losing the document due to any external factors such as environmental condition, etc. (Reliability)

These conditions are the same for your personal PCs.

• Scaling the memory/processor is hard
• Security for the data is hard
• Getting data from a device outside the network is hard
• Lightning can cause damage to the personal PC/server

This is the time where cloud (In our breakdown case -Bank) comes to the rescue. Let us look at how a bank/cloud can mitigate the same issues mentioned above.

• SLA — Service Level Agreement

So back to the definition with our scenario

cloud computing (bank) is the delivery of computing services(banking services) — including servers(ATMs), storage(lockers), databases, networking, software, analytics(transaction details), and intelligence — over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale.

Hope you got an idea of what is Cloud?
