A to Z of Cloud Computing – Everything You Need To Know About It

Do you ever hear the word “Cloud” in recent times? Do you know what is cloud computing, what it means, and what it is used for? If not, then read this article till the end. I am going to give complete detail on everything you need to know about Cloud Computing.

Before you start learning about cloud computing you must know what cloud means. The cloud includes the software and services that run with the help of the Internet, instead of locally on your computer. You can access almost all cloud services through a Web browser like Firefox or Google Chrome, and some companies offer dedicated mobile apps.

Cloud storage uses at least one data server connected to the Internet to work. Suppose if you send a file over the Internet to the data server, the cloud storage saves a copy. If you want to retrieve this information, you access the data server through a web-based interface.

At the beginning of industry and commerce, we have needed better ways to store our personal and private data and access it whenever required. Today, we store it on hard drives of computers and servers, while valuable information was stored physically on paper in the pre-computer era. In these hard drives and servers, you can store, process, and retrieve a required amount of data quickly and comfortably.

But there are some limitations for both hard drives and servers. The need for storage that can store and the process has become a priority with the rate at which today’s businesses and industries are growing. This is where Cloud Computing has actually started!

Before the arrival of Cloud Computing platforms, businesses depended mostly on servers, databases, hardware, software, and other alternatives to take their businesses online. Companies bought these components and used them to check whether their website or applications reached the users or not.

Businesses also needed many experts to manage their hardware and software components, and also to monitor the infrastructure. Though this approach was practical, the businessmen faces many unique issues, like the high cost of setup, complex components, and limited storage space, to name a few. With the emergence of Cloud Computing, all these problems were solved.

Netflix is one example of an organization that uses cloud services. It provided billions hours of service to customers around the globe by running on Amazon Web Services(AWS-a cloud service provider). In Netflix, you can order products/services from almost anywhere in the world, using PCs, tablets, or mobile devices.

Network-based access to communication tools like emails and calendars are also allowed by cloud. Whatsapp is also an example for cloud-based infrastructure as it comes in communication. You can store all the messages and information of whatsapp in service providers hardware.

This is all about a cloud and how it is used. So, now we shall go for cloud computing and see in-depth in it.

What a Cloud Computing Is All About?

Generally, Cloud Computing is a network of remote servers which you can host on the internet for storing and retrieving data. Many IT services are provided by the cloud such as servers, databases, software, virtual storage, and networking, among others. According to yo layman, Cloud Computing is known as a virtual platform that allows you to store and access your data over the internet without any limitations.

And hence, the companies that offer all the above-mentioned services are called cloud providers. These cloud providers provide you with the ability to store and retrieve data and run applications. And you can also manage them through configuration portals. Amazon Web Services and Microsoft Azure are two of the best cloud providers available today.

We shall consider a basic example of cloud computing to know more about it clearly.

Assume that you are traveling on a bus or train, you take a ticket and sit back in your seat till you reach your destination. Similarly, other passengers also take tickets and travel on the same bus with you and it hardly bothers you where they go. When your stop comes you will thank your driver before you get off the bus. Cloud computing works just like that bus, carrying data and information for various users and allowing you to use its service with less cost.

Due to the increase in computer and Mobile users, data storage has become an important part of all fields. Even large and small-scale businesses today are spendings a huge amount of money to maintain and secure their data. A strong IT support and a storage hub are needed to store data. However, all businesses cannot afford the high cost of in-house IT infrastructure and backup support services. For such companies, Cloud Computing is a cheaper solution. The efficiency of Cloud Computing in storing data, computation, and less maintenance cost has succeeded to attract even bigger businesses as well.

Cloud computing also decreases the hardware and software usage from the user’s side. The only thing that users must be able to run is the cloud computing systems as simple as a Web browser. They can interface software, and the Cloud network takes care of the rest. The present technology has experienced cloud computing at this moment. Some of the popular cloud services we are still using are mail services like Gmail, Hotmail, Yahoo, etc.

Now you came to know what is cloud computing. Next, you will see the various types of cloud computing, their uses, and their benefits.

Types of Cloud Computing

Cloud computing has mainly four types or divisions. They are Public Cloud, Private Cloud, Hybrid Cloud, and Community Cloud. Let us dig a little deep into them.

Public Cloud:

Everything is stored and accessed through the internet in a Public Cloud. It is open to all to store their data and access information via the Internet using the pay-per-usage method. This distribution system allows you only if you have proper permission to access some of the applications and resources. The most interesting thing about the public cloud is that you own none of the components present in it, it may be the hardware, software, or application. All the components of the cloud are managed only by the service provider. Amazon elastic compute cloud (EC2), IBM SmartCloud Enterprise, Microsoft, Google App Engine, and Windows Azure Services Platform are examples of the public cloud.

Private Cloud:

You can call a private cloud also as an internal cloud or corporate cloud. Because the private cloud is used by organizations to build and manage their own data centers internally or by a third party. You can also deploy it using Opensource tools such as Openstack and Eucalyptus. You can run this infrastructure on a private network, which means it can only be accessed by the people who are present in that respective network. VMware cloud and some of the AWS products come under a private cloud.

Hybrid Cloud:

A hybrid Cloud is an extremely interesting form of Cloud Computing because it contains the functionality of both public and private clouds. Many organizations use the hybrid cloud to keep some of their data locally and some in the cloud. NASA is a well-known example of an organization that uses a hybrid cloud to store its data. It stores sensitive data and uses the public cloud to save and share data that can be viewed by the public worldwide.

Google Application Suite (Gmail, Google Apps, and Google Drive), Office 365 (MS Office on the Web and One Drive), and Amazon Web Services are other examples of the Hybrid Cloud.

Community Cloud:

With the help of the Community cloud, all systems and services are accessible by a group of several organizations to share the information between the organization and a specific community. It can be owned, managed, and operated by one or more organizations in the community, a third party, or a combination of them.

What Is the A to Z of Cloud Computing?

Amazon Web Services (AWS):

Amazon Web Services is a collection of cloud computing services that make a full-scale cloud platform offered by Amazon. Amazon Web Services offers multiple cloud services including the IaaS, PaaS, and SaaS models of cloud computing. AWS is a famous cloud service provider, with nearly 30% global market share in cloud IaaS, as of 2015. Amazon EC2, Amazon Elastic Beanstalk, and Amazon S3 are the popular services provided by AWS.

Application:

A group of computer programs designed to allow a user to perform a set of functions or tasks is known as an Application in Cloud Computing.

Application Programming Interface (API):

In an application programming interface (API) the user can access all information from another service and integrate this service into their own application. You can use APIs to share limited functionality between programs.

Backend-As-A-Service (BAAS):

Backend as a service (BaaS), or mobile backend as a service (mBaaS) is one of the components of cloud computing in which the service provider provides web and mobile application developers with tools and services. So that you can create a cloud backend for their applications. Usually, custom SDKs and APIs are used by BaaS to give developers the ability to connect their applications to backend cloud storage and features such as user management, push notifications, and social network integration.

Backend Database:

Any database that is accessed indirectly by the user is known as a Backend Database in cloud computing.

Big Data:

In Cloud Computing, the term used to describe unconventional data sets which are too complex to be dealt with using traditional data-processing techniques is known as Big Data.

Cloud Application:

The Cloud Application is an application that runs in the cloud.

Cloud Backup:

In Cloud backup, you can backup your data to a remote, cloud-based server.

Cloud Management Platform (CMP):

A cloud management platform (CMP) is a product where you can manage public, private, and hybrid cloud environments.

Cloud Marketplace:

A cloud marketplace is an online marketplace, operated by a cloud service provider (CSP), where you can browse and subscribe to build-in software applications and developer services. Amazon’s AWS Marketplace and Microsoft’s Azure store are some examples of cloud marketplaces.

Cloud Migration:

Cloud migration is the process of transferring all of or a piece of a company’s data, applications, and services from on-premise to the cloud.

Data Migration:

When you move the data between two or more storage systems, data formats, warehouses, or servers. This process is called Data Migration.

Database:

In Cloud Computing, an organized collection of data is known as a Database.

DevOps:

A combination of “development” and “operations,” is known as DevOps. It includes the tasks performed by an organization’s applications development and systems operations teams.

Elasticity:

In cloud computing, elasticity refers to the ability of a system to adapt to changing workload demand by provisioning and de-provisioning pooled resources so that necessary resources match the current demand.

Enterprise Application:

An enterprise application is a software that is used for large-scale business.

Enterprise Resource Planning (ERP):

This is a software that allows a business or organization to manage a combination of integrated applications. These applications are used to collect, manage, and store data on various business activities.

Extensibility:

Extensibility is used to add new runtime and framework support via community buildpacks in Cloud Computing.

Federated Database:

It is a system in which multiple databases appear to function in one form. The databases involved in this kind of system exist independently of the others. When you combine the different databases, one federated database is formed.

Hypervisor:

A hypervisor is also called a virtual machine monitor (VMM). It is a piece of software that allows you to share resources of physical devices among virtual machines (VMs) running on top of that physical hardware. The hypervisor is used create, run, and manage VMs.

Integrated Development Environment (IDE):

An integrated development environment (IDE) is an application that provides you with a programming environment when you are developing any software. Usually, a code editor, automation tools, and a debugger are included in IDE.

Microservices:

Microservices also known as microservice architecture are a way of designing applications in which complex applications are built out of a group of small, independently deployable services. These ‘microservices’ can run their own processes and communicate with one another. They use lightweight mechanisms such as language-agnostic APIs for communication. Microservices can even be written in different languages.

Open Source:

In an open-source development model, the source code of a product is made openly available to the public. OpenStack and CloudFoundry are open-source cloud computing platforms.

Virtual Machine (VM):

A virtual machine is just like a physical hardware computer that runs an operating system or application environment. The end-user will have the same experience on a VM as in dedicated hardware.
