The Beginner's Guide to Cloud Computing: A blog around cloud computing

Updated: Sep 12, 2022



Cloud computing is a type of computing where files and programs are stored on

remote servers accessed over the internet, instead of on a local server or personal

computer. The cloud computing model allows users to access their data and

applications from any device or location, as long as they have an internet connection.

In the past, users would have to save their documents and files to a physical hard

drive, USB drive, or disk. With cloud computing, there is no need for any physical

hardware component.


Cloud computing services are classified into three broad categories:

software-as-a-service (SaaS), platform-as-a-service (PaaS), and

infrastructure-as-a-service (IaaS).


SaaS is the most prevalent type of cloud service. A lot of us use it on a regular basis.

SaaS delivers software over the Internet through an app or web browser. Some SaaS

solutions are free but many come with a monthly or yearly subscription fee to

continue using the service.


Requiring no hardware installation or management, SaaS solutions are a big

hit in the business world. Notable examples include Salesforce, Dropbox or

Google Docs.


Platform as a Service

PaaS is a cloud-based environment that helps with web application development

and deployment. It supports the full lifecycle of applications, from building to testing

to deploying to managing and updating. The service also includes development

tools, middleware and business intelligence solutions. Some notable examples of

PaaS providers are Windows Azure, AWS Elastic Beanstalk and Google App Engine.

Infrastructure as a Service


IaaS can be thought of as the foundation that other cloud services are built on. It

provides users with capabilities like data storage and servers, which are all housed in

the cloud. This type of service is appealing to businesses because it gives them

access to large programs and applications without having to invest in a physical

infrastructure. Some well-known IaaS providers include DigitalOcean, Amazon EC2

and Google Compute Engine.


Mechanism Of Cloud Computing

The cloud is a great place to store and share information. It's accessible from

anywhere there is an internet connection and it's relatively safe and secure. Cloud

applications have a host, which is the company responsible for maintaining the data

centers that provide the security, storage capacity and computing power needed to

maintain all of the information users send to the cloud.


The cloud is a major player in the hosting market, with companies like Amazon

(AWS), Microsoft (Azure), Apple (iCloud) and Google (Google Drive) being the most

prominent. However, there are also many other hosting companies, both large and

small. These companies can sell the rights to use their clouds and store data on their

networks. In addition, they offer users an ecosystem that can communicate between

devices and programs. For example, you can download a song on your laptop and it

will be instantly synced to iTunes on your iPhone.


It follows three delivery models:

1) Public

This is the most common and all of the players mentioned above (Amazon,

Microsoft, Apple & Google) run public clouds accessible anywhere with login

credentials and the right web app.

2) Private

This model offers the same kind of flexibility as the public cloud, but with the

infrastructure needs (hosting, data storage, IT staff, etc.) provided by the

companies or users of the service. Additionally, the restricted access and

hands-on management of hosting gives the private model an extra layer of

security.

3) Hybrid

Hybrid cloud computing is a combination of the public and private models.

The two cloud types are linked over the internet and can share resources


when needed (e.g., if the private cloud reaches storage capacity or becomes

corrupted, the public cloud can step in and save the day).


Cloud Application Development

Cloud application development is the process of building a Cloud-based app. This

process involves various stages of software development, which readies your app to

be launched. The best teams implementing Cloud app development use DevOps

practices and tools, such as Kubernetes. However, an experienced app development

company should be able to build your Cloud app using any technology you prefer.

The majority of apps built with Cloud technology are highly dependent on the Cloud

to function.

Application development on Cloud infrastructure has many benefits for businesses,

including reduced development costs, the ability to work with remote teams, and

shorter project timelines when used in conjunction with software development

methodologies like Agile. However, not all companies have the experience necessary

to perform all of the complex aspects of app development using the Cloud. As such,

businesses that are looking to develop digital products like web-based Cloud

applications need to ensure that they partner with a reputable and experienced

Cloud app development company.

Examples of cloud based applications


1) Miro

A virtual board is a great tool for collaborating with other users. You can use it

to share ideas, get feedback, and work together on projects in a number of fun

and creative ways.

2) Figma: a powerful Cloud-based design app that is gaining many fans thanks

to its collaborative nature.

3) Dropbox or Google Drive: easily store your files on the Cloud and make them

available for others, wherever they are.

Most Cloud-based apps don't lack any collaboration features. One major advantage of

Cloud apps is the ability to collaborate with users all over the world, even in real-time.


Advantage of cloud based applications

In cloud application development, the app’s data is stored in the cloud infrastructure

and could be partly cached on a user’s device. This means there are minimum

requirements for devices to run the application.

The cloud infrastructure can temporarily store information on a user’s device to allow

the user to access it while offline. Once the user is online again, the cloud app is

updated and uploads the generated data from offline to the cloud storage location.

You can set up backup schedules as well data optimization, compression and

encryption as a user in any way you want.

A cloud application can be accessed with the help of any internet-connected device,

including desktop, tablet, and mobile. This helps the user to get independent of

browser capacities.

Cloud-based applications also offer access to third-party cloud computing
