What is Cloud Computing? You may have heard this word too many times, but do you know what this Cloud Computing is? Why is it getting listened to so much these days? As we know, that computer network technologies have grown a lot in the last 20 years.
Since the Internet (the most popular computer network) has revealed its existence since then, the field has been much advancement, particularly with considerable research in Distributed Computing and Cloud Computing technologies such as a field.
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 Cloud Computing, then you must also have an understanding of Distributed Computing.
Global Industry Analyst has said that this global cloud computing service market will become a business of up to $ 327 billion by 2020. Nearly all companies are using Cloud Computing service today’s more, be it directly or indirectly.
For example, if we talk, whenever we use the service of Amazon or Google, then we use all our are storing the data in the cloud. If you use Twitter, then you use cloud computing service indirectly.
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 Cloud Computing is? And why is it becoming so popular?
What is Cloud?
Talking about Cloud, it is the design of an extensive interconnected network of servers designed to deliver computer resources. And there is no concept of the precise location where data is coming from and where it is going.
If I say in easy language, he will feel that he uses enormous formless computing power to use it. According to his needs, the user can do everything from his email to the mobile application mapping.
There is nothing like saying ” The Cloud ” in the language of Business. Cloud Computing is a collection of licensed service provided by different vendors.
Cloud service replaces them with different products in place of technology management and technology acquisition. These products are managed from elsewhere, and one thing they are active only when 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 say, Cloud Computing is such a style of computing that massively Scalable and flexible IT-related capabilities are provided as a service with the help of Internet Technologies.
Facilities like infrastructure, platform, application and storage space are available in these services. In this, the users use the services according to their needs and pay the money for the services they use. For this, they do not need to build their infrastructure.
Nowadays there is a lot of competition in the world and such a situation, 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 meet these requirements, we solved this problem. People used the Cloned distributed computing technology not to emphasise mainframe computing. Because of this, big businesses started doing all their work very quickly.
For example, Facebook has 757 million active users and sees about 2 million photos daily, around 3 billion images 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; instead, we need something better that can work. Therefore, to do such computing, Cloud Distributed Computing is the need of the hour.
Examples of Cloud Computing
- YouTube is an excellent example of cloud storage that hosts video files of millions of users.
- Picasa and Flickr, which hosts digital photographs of crores of users on their server.
- Google Docs 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.
Cloud Computing Characteristics and Benefits
If seen, Cloud Computing has many attractive benefits that will be very useful for businesses and people. There are five main benefits of cloud computing:
- Self-service provisioning: End users can do any work according to their need which they need most. With this, the standard requirements are IT administrators, who used to manage and provision your compute resources earlier, and they are not needed anymore.
- Elasticity: Companies can increase and earn it according to the computing of their 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 at a granular level. So that users only have to pay for the help and workloads that they use.
- Workload resilience: Cloud service providers often use redundant resources to get resilient storage. With it, they can continue the vital work of users who are familiar with multi global regions.
- Migration Flexibility: Organization can transfer some workloads from one cloud platform to another according to their needs, without any difficulty and automatically, saving money.
History of Cloud Computing
If we talk about Cloud computing, it was born in the tens of 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 a large-scale Internet. The availability of bandwidth was not available till 1990. After which, it was possible to think of computing as a service.
In 1990, Salesforce became the first commercially enterprise Successfully implemented SaaS. After that, in 2002, AWS did many services like online storage, machine learning, computation provide.
Today, many mega providers like Microsoft Azure, Google Cloud Platform, and AWS provide cloud-based service to other individuals, small business and global enterprise.
Cloud Computing vs Distributed Computing
If I talk about distributed computing, it provides collaborative resource sharing by connecting with other users and resources.
Distributed Computing Always tries that 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) provide can do.
While speaking of Cloud Computing, it believes in delivering service in the on-demand environment to achieve the targeted goal. 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.
Distributed Computing is divided into three types
Distributed Information Systems
The main objective 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 computing 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 systems, computers connected in the network, are interconnected by message to track their activity.
Cloud Computing is divided into four types.
1. Private Cloud
This is a cloud infrastructure that dedicatedly hosts all the applications of a particular IT organisation. Its complete control is over the data so that the security is unlikely to breach.
2. Public Cloud
This type of cloud infrastructure is hosted by another service provider and which is later made public. Users do not have any control in such a cloud, nor can they see the infrastructure.
For example, both Google and Microsoft own their cloud infrastructure and later give access to the public.
3. Community Cloud
This is a multi-tenant cloud infrastructure in which the cloud is shared between other IT organisations.
4. Hybrid Cloud
This Combination is two or more different types of clouds (Private, Public and Community) only then. Hybrid cloud infrastructure is formed where each cloud remains a single entity. Still, all the clouds combine to form multiple deployment models. The fides of which are slow.
In Distributed Computing, the task is distributed between different computers. So that computational functions can be performed at the same time.
Cloud Computing Systems use an on-demand network model that provides access to a shared pool of computing resources with the help of Remote Method Invocations.
Types of Cloud Computing | Types of cloud computing
Cloud computing can be mainly divided into three parts which are: IaaS, PaaS, and SaaS.
Cloud Computing Models
1) Infrastructure as a service (IaaS)
These services are self-service models 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 for software developers to manage the computing infrastructure from centralised IT operations.
Examples – Email services: Gmail, Outlook.com
3) Software as a service (SaaS)
SaaS accesses the web to deliver managed by third-party vendors, and whose user interface can only be accessed from the client.
Application Building: Google App Engine, SAP Hana, 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 many benefits for hardware and software, which seemed impossible a few years ago.
Now a virtual machine needs just a few minutes to run. Cloud Computing has changed the attitude of companies and businesses. It has become the first choice because if someone does business with proper planning, strategy, and budget properly, he will succeed.
And scientists are doing more and more research to make it better.
Note – The real funda of Cloud Computing is “You can access any of your data from anywhere in the world”, e.g. G-Mail, Google Drive etc.
