What is Cloud Computing, its uses and advantages

What is Cloud Computing? You may have heard this word too many times, but do you know what this Cloud Computing is all about, why it is being heard so much these days. As we know that computer network technologies have grown a lot in the last 20 years. Ever since Internet (the most popular computer network) has revealed its existence, there has been a lot of advancement in the field of computer network and there has been a lot of research especially in the fields of technologies like Distributed Computing and Cloud Computing.

These technical terms are the concept of both Distributed Computing and Cloud Computing are often the same, there are some inequalities in both. So if you want to understand about Cloud Computing then you must also understand Distributed Computing. Global Industry Analyst has told that this global cloud computing service market will become a business of up to $ 327 billion this year. Nearly all companies are using Cloud Computing service in today's world, be it directly or indirectly.

For example, if we talk, whenever we use Amazon or Google's service, then we are storing all our data in the cloud. If you use Twitter, then you indirectly use cloud computing service. Distributed Computing and Cloud Computing are both so popular because we needed better computing networks so that our data could be processed faster. So what is cloud computing today? You will know more about this in this article. So, let's start delaying and know what is this Cloud Computing? And why is it becoming so popular.

What is Cloud?

Talking about Cloud, it is the design of a large interconnected networks of servers that have been designed to deliver computer resources. And there is no concept of precise location where data is coming from and where it is going. If I say in easy language, if a user uses it, then he will feel that he is using a huge formless computing power, in which the user can do everything from his email to the mapping of mobile application according to his need.

There is nothing like saying "The Cloud" in the language of Business. Cloud Computing is a collection of licensed service that is provided by different vendors. Cloud service replaces them with different products in place of technology management and technology acquisition and these products are managed from elsewhere and one thing remains active only when it is needed.

What is Cloud Computing?

If someone provides a service through the Internet, it is called Cloud Computing. This service can be anything like Off Site Storage or computing resources. Or simply, Cloud Computing is such a style of computing that massively scalable and flexible IT-related capabilities are provided as service with the help of Internet Technologies. Facilities like infrastructure, platform, application and storage space are available in these services. In this, users use services according to their needs and pay the money for the services they use. For this, they do not need to build their own infrastructure.

Nowadays there is a lot of competition in the world and in this way people need service on the Internet at all times, without any delay. If an application ever freezes, then there is a lot of dissatisfaction among the people. People need the service they need 24/7. To fulfill this requirement, we cannot emphasize on the old mainframe computing, so people used Cloud distributed computing technology to solve this problem. Because of which big businesses started doing all their work very easily.

For example, Facebook, which has 757 million active users and who sees about 2 million photos daily, around 3 billion photos are uploaded every month, 1 million websites use Facebook to do 50 million operations per second. In such a situation, the traditional computing system cannot solve these problems, rather we need something better that can do this job. So to do such computing, Cloud Distributed Computing is the need of the hour.

Examples of Cloud Computing

YouTube is a great example of Cloud storage that hosts video files of millions of users.
Picassa and Flickr which hosts digital photographs of crores of users in their server.
Google Docs which is another great example of cloud computing that allows users to upload their presentations, word documents and spreadsheets to their data servers. Along with this, there is also an option to edit and publish those documents.

Characteristics and Benefits of Cloud Computing

If seen, Cloud Computing has many attractive benefits that are going to be very useful for businesses and people. There are 5 main benefits of cloud computing:

Self-service provisioning: End users can do any work according to their need which they need most. From this, the traditional needs are IT administrators, who used to manage and provision your compute resources earlier, they are not needed anymore.

Elasticity: Companies can increase and earn it according to their computing needs. It is a benefit that as before there was a lot of investment on the local infrastructure, it has completely stopped now, it benefits the companies a lot.

Pay per use: Compute resources are measured in granular level. So that users only have to pay for the resources and workloads that they use.

Workload resilience: Cloud service providers often use redundant resources so that they can get resilient storage and with this they can continue the important work of users who are familiar in multi global regions.

Migration Flexibility: Organization can transfer some workloads from one cloud platform to another according to their requirement without any hassle and automatically which saves money as well.

History of cloud computing

If we talk about cloud computing, it was born in the 1960s. When the computing industry assumed computing as a service income utility based on its potential benefits. But earlier computing, connectivity and bandwidth were both lacking due to which it was not possible to implement computing according to a utility. This was not possible until the availability of Internet bandwidth was achieved in a large scale till 1990. After which it was possible to think of computing as a service.

In 1990, Salesforce successfully implemented commercially enterprise SaaS for the first time. After which AWS did in the year 2002, which used to provide many services like online storage, machine learning, computation. Today there are many mega providers like Microsoft Azure, Google Cloud Platform which together with AWS are providing cloud-based service to other individuals, small business and global enterprise.

Cloud Computing vs. Distributed Computing

1) Goals

If I talk about distributed computing, it provides collaborative resource sharing by connecting with other users and resources. Distributed Computing always tries to provide administrative scalability (number of the domain in registration), size scalability (number of processes and users), and geographical scalability (maximum distance between the nodes in the distributed system).

While speaking of Cloud Computing, it believes in delivering service in the on-demand environment so that the targeted goal can be achieved. Along with this it also believes in providing more scalability and transparency, security, monitoring, and management. In Cloud Computing, services are delivered with transparency without physical implementation in the cloud.

2) Types

Distributed Computing is divided into three types:

Distributed Information Systems : The main purpose of these systems is to distribute this information through various communication models across different servers such as RMI and RPC.
Distributed Pervasive Systems : These systems are mainly made up of embedded computer devices such as portable ECG monitors, wireless camera, PDA's and mobile devices. These systems can be identified to compare their instability to any traditional distributed systems.
Distributed Computing Systems : In these types of systems, the computers which are connected in the network are interconnected by message to track their action.

Cloud Computing is divided into four types:

Private Cloud : It is such a cloud infrastructure that dedicate hosts all the applications of a particular IT organization, so that its complete control is over the data so that the security is unlikely to breach.
Public Cloud : This type of cloud infrastructure is hosted by other service providers and which are later made public. In such a cloud, users do not have any control nor can they see the infrastructure. For example, both Google and Microsoft own their cloud infrastructure and later give access to the public.
Community Cloud : This is a multi-tenant cloud infrastructure, in which the cloud is shared between other IT organizations.
Hybrid Cloud : These are Combination 2 or more different types of clouds (Private, Public and Community) only then Hybrid cloud infrastructure is formed somewhere where each cloud remains as a single entity, but all the clouds combine to form multiple deployment models, which are very slow.

3) Characteristics

In Distributed Computing, tasks are distributed between different computers so that computational functions can be performed at the same time with the help of Remote Method Invocations while on-demand network model is used in Cloud Computing Systems which provides access. Is shared pool of computing resources.

Types of Cloud Computing

Cloud computing can be mainly divided into three parts: IaaS, PaaS, and SaaS.

1) Infrastructure as a service (IaaS)

These services are of self-service models which are used for monitoring, accessing and managing the infrastructure from a remote location. Examples - Servers, Firewalls, Routers, CDN

2) Platform as a service (PaaS)

It provides a line of self-service modules of software developers to manage the computing infrastructure from centralized IT operations. Examples - Email services: Gmail, Outlook.com

3) Software as a service (SaaS)

SaaS accesses the web to deliver applications that are managed by third-party vendors and whose user interface can only be accessed from the client.

Application Building: Google App Engine, Cloud Foundry

Cloud Computing has changed the entire computing industry. It has completely changed the look of businesses and the IT infrastructure as well. It provides a lot of benefits for hardware and software which seemed quite impossible a few years ago. Now a virtual machine needs just a few minutes to run. Cloud Computing has changed the perspective of companies and businesses. It has now become the first choice of all because if someone does business with proper planning, strategy and budget properly, then he will surely get success. And scientists are doing more and more research to make it better.
