What is Cloud Computing – An Ultimate Guide to Beginners

 

Cloud computing delivers services over the internet, including data storage, networking, servers, databases, analytics, and software.

Watching movies or TV shows, playing games, storing images and other files, and using online services to send emails are all possible due to cloud computing.

Previously, if you wanted to create a web-based application and deploy it to the web, you would need to purchase a hardware server. As a result, we have to spend a lot of money on servers, but we don’t need to purchase hardware for cloud computing. In cloud computing, you have to buy a service. Cloud computing follows a pay-as-you-go model, so you only need to pay for the services you use.

Types Of Cloud Computing :

There are four different types of clouds :

  1. Public Clouds
  2. Private Clouds 
  3. Hybrid Clouds
  4. Multi Clouds 

 

Public Clouds:-

Public clouds are a category of cloud computing that provides shared resources, servers, and services to the general public over the internet. The three types of services provided by a public cloud are 

Infrastructure as a Service (IaaS)

Platform as a Service (PaaS)

and Software as a Service (SaaS).

When a company uses a public cloud, it purchases IT Infrastructure.

AWS, Microsoft Azure, and GCP are the most popular public clouds. Customers and businesses can rent computing power, storage, and applications on demand via the internet from anywhere in the world.

The best advantage of using the public cloud is that you can use software and services like Microsoft Office 365 or Salesforce without investing in or managing on-premises Infrastructure.

Private Clouds:-

Private clouds are created to help you build clouds in your environment. It’s cost-effective and easy to deploy.

The private cloud has three main benefits:

  1. Greater hardware utilization.
  2. Rapid deployment of new services.
  3. Customized business processes that can be implemented quickly. 

Hybrid Clouds:-

Hybrid clouds are a combination of private, public, and hosted environments. A hybrid cloud is a service that delivers the best of both private and public cloud features. You get the security of a private cloud. But you also get the elasticity, flexibility, and cost savings of a public cloud.

A hybrid cloud combines public and private clouds to give customers additional flexibility and greater control over their computing environment. 

Multi Clouds:-

A multi-cloud computing model is one in which an organization uses a combination of clouds, such as two or more public clouds, two or more private clouds, or a mix of both public and private clouds.

Multi-cloud is a combination of SaaS, PaaS, and IaaS services.

IT administrators can manage a multi-cloud infrastructure using tools provided by cloud service providers. Alternatively, they can use a multi-cloud management solution to reduce complexity. There is no single best practice guideline for managing multi-cloud because each organization’s use case is unique.

Cloud Computing Service Models:-

Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) are cloud computing service models that define how much control you have over your server and data storage systems and applications. 

IaaS (Infrastructure As A Service):- 

  • IaaS (Infrastructure as a Service) is one of the most commonly used cloud computing services.
  • Its the most basic service model in which you can rent IT infrastructure – servers and virtual machines (VMs), storage, networks, and operating systems from a cloud provider.
  • The customer can rent storage, network, and computing power on a pay-per-use basis.

PaaS (Platform As A Service):- 

  • Platform-as-a-Service (PaaS) is a cloud computing model that provides a platform and infrastructure to application developers.
  • The computing resources are virtualized and available on demand.
  • Once it has been created, PaaS can quickly launch the application in the cloud.
  • You pay for what you use by using PaaS.
  • AWS Elastic Beanstalk, Lambda, Azure WebApps, Functions, Azure SQL DB, Cloud SQL DB, and Oracle Cloud Oracle Database Cloud Service are examples of PaaS.

SaaS ( Software As A Service ):- 

  • Software as a Service (SaaS) is a cloud computing model that provides software applications over the internet rather than selling them as standalone software packages.
  • SaaS is a pricing model for software where the vendor develops application software for usage on a subscription basis.
  • When you use a SaaS provider, you don’t have to worry about service maintenance or underlying infrastructure management.
  • Popular SaaS software services are Microsoft Office 365, Oracle ERP/HCM Cloud, SalesForce, Gmail, and Dropbox.

Why do data scientists and data engineers need to understand the cloud and its data services?

Application workloads moving to the cloud:- 

Cloud computing enables businesses to launch applications more quickly and without the need for extensive maintenance, which the service provider handles. This also leads to more efficient use of computing resources, which can be tailored to meet the needs and requirements of a business on a case-by-case basis.

Having a deeper understanding of these cloud applications can help make the best use of them:- 

Workloads for big data and analytics applications are also on the move. The data science and engineering community must thoroughly understand these cloud computing services to make the best use of them in their analytics work.

Data analysis on cloud services:- 

Instead of moving vast amounts of data to a central server and then doing the analysis, companies use the cloud to store their data and do the analysis without having to build a server.

  • Cloud Computing Characteristics that help the steadfast data analysis process
  • A shortage of such skills, and the compensation is highly competitive.
  • Cloud computing services for data science – AWS Sagemaker, Azure Data factory

Cloud Job Demands:- 

According to the job listing portal Monster, the top skills demanded by cloud professionals include cloud computing, AWS/Azure, cloud migration, SAP, cloud security, and Machine Learning/AI.

 

Share of cloud jobs in % over six months in 2021

With over 608,000 cloud professionals across all verticals in India, demand for cloud-related jobs has increased by more than 40% since last year.

 

 Experience-Level jobs data for the last 3 months

 

As of November 2021, intermediate-level workers with 4-6 years of experience held the highest percentage of cloud positions, contributing to 44 % of the cloud workforce. With 29 %, Entry Level Talent with 0-3 Years of Experience came in second, indicating a positive outlook for newcomers to the business.

Cloud Computing Plays an Important Role in the COVID-19 Pandemic:-

With three years in a row in a pandemic, its a generational shift where IT engineers will be used to working on-premise in a company, but from startups to MNCs like Netflix and Spotify moved their storage, analytics, and machine learning & number-crunching programs online, it will be going to hard to find an engineer who hasn’t worked on cloud-based software development!

During the COVID-19 crisis, cloud computing provided collaboration, communication, and important online services. Meanwhile, during the COVID-19 pandemic, it was necessary for people to work from their homes. But they had to communicate and collaborate online. Thus, we see that cloud computing plays an important role in effectively tackling the challenge of working from home. Cloud computing helps minimize the spread of this virus by providing online services.

We conclude that the agility and flexibility that cloud technology provides open up new ways of working, operating, and doing business.
