What is Cloud Computing, you might have heard this word many times, but do you know what is this Cloud Computing, why it is being heard so much these days? As we know that computer network technologies have made a lot of progress in the last 20 years.
Ever since the Internet (the most popular computer network) has expressed 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 field of technologies like Distributed Computing and Cloud Computing.
These technical terms, the concept of both Distributed Computing and Cloud Computing are almost the same, just there are some differences in both. So if you want to understand about Cloud Computing, then you must also have an understanding of Distributed Computing.
Global Industry Analyst has to say that this global cloud computing service market will become a business of up to $327 billion by 2020. Almost all companies are using Cloud Computing service in today’s world, whether directly or indirectly.
For example, if we talk, whenever we use the service of Amazon or Google, then we are storing all our data in the cloud. If you use Twitter then you indirectly use cloud computing service.
Both Distributed Computing and Cloud Computing are so popular because we needed better computing networks so that our data could be processed faster. So today we have what is Cloud Computing? You will know about it completely in this article.
Then what is the delay, let’s start and know what is this Cloud Computing? And why is it becoming so popular.
What is Cloud
Talking about the cloud, it is the design of a large interconnected network of servers which is designed to deliver computer resources. And there is no concept of precise location where the data is coming from and where it is going.
If I say in simple 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 mapping of mobile application according to his needs. .
In the language of business, nothing like this happens by saying “The Cloud“. Cloud Computing is a collection of licensed service that is provided by different vendors.
Cloud Service replaces them with different products instead of technology management and technology acquisition and these products are managed from some other place and one thing they remain active only when it is needed.
What is Cloud Computing
If someone provides a service through the Internet, then it is called Cloud Computing. This service can be anything such as Off Site Storage or computing resources.
Or rather, 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, users use services according to their needs and pay for those services which 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 such a situation, people need service on the Internet all the time, that too 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 cannot stress on the old mainframe computing, so people used cloud distributed computing technology to solve this problem. Due to which big businesses started doing all their work very easily.
For example, Facebook, which has 757 million active users and who view 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 work. That’s why Cloud Distributed Computing is the need of the hour to do such computing.
Examples of Cloud Computing
- YouTube is a great example of cloud storage which hosts video files of millions of users.
- Picasa and Flickr which host digital photographs of crores of users in their servers.
- Google Docs which is another great example of cloud computing which allows users to upload their Presentations, Word Documents and Spreadsheets to their data servers. Along with this, it also gives the option to edit and publish those documents.
Characteristics and Benefits of Cloud Computing
If seen, there are many attractive benefits of Cloud Computing which 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 the most. Due to this the traditional need of IT administrators, who used to manage and provision your compute resources earlier, is not needed any more.
- Elasticity: Companies can increase and earn according to their computing needs. It is advantageous that as earlier there was a lot of investment on the local infrastructure, now it has stopped completely, it benefits the companies a lot.
- Pay per use: Compute resources are measured in granular level. So that users have to pay only for those resources and workloads which 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 present in multi global regions.
- Migration Flexibility: Organizations can transfer some workloads from one cloud platform to another according to their needs, that too without any problem and automatically, which also saves money.
History of cloud computing
If we talk about cloud computing, then it was born in the decade of 1960. When the computer industry adopted computing as a service income utility on the basis of its potential benefits. But there was a lack in both the earlier computing, connectivity and bandwidth, due to which it was not possible to implement computing according to a utility.
This was not possible until the 1990s until the availability of Internet bandwidth on a large scale. After which it became possible to think of computing as a service.
In 1990, Salesforce successfully implemented enterprise SaaS for the first time. After which AWS did in 2002, which provided many services such as online storage, machine learning, computation.
Today there are many small and big providers like Microsoft Azure, Google Cloud Platform, which are providing cloud-based service to other individuals, small business and global enterprise in collaboration with AWS.
Cloud Computing vs. Distributed Computing
If I talk about Distributed Computing, then 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 talking about Cloud Computing, it believes in delivering service in an on-demand environment so that the targeted goal can be achieved. Along with this, it also believes in providing greater scalability and transparency, security, monitoring, and management.
In Cloud Computing, services are delivered with transparency without any physical implementation in the cloud.
Distributed computing is divided into three types
Distributed Information Systems
The main purpose of these systems is to distribute this information across various communication models of different servers through RMI and RPC.
Distributed Pervasive Systems
These systems are mainly made up of embedded computing devices such as portable ECG monitors, wireless cameras, PDA’s and mobile devices. These systems can be identified by comparing their instability to any traditional distributed systems.
Distributed Computing Systems
In these types of systems, computers that are connected to the network communicate with each other through messages to track their actions.
Cloud computing is divided into four types
1. Private Cloud
It is such a cloud infrastructure that dedicatedly hosts all the applications of a particular IT organization so that it has complete control over the data so that the possibility of a security breach is negligible.
2. 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 own 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 among other IT organizations.
4. Hybrid Cloud
These combinations are 2 or more different types of clouds (Private, Public and Community) Only then a Hybrid cloud infrastructure is formed where each cloud remains a single entity, but all the clouds combine to create multiple deployment models, which are very slow. Huh.
In Distributed Computing, the task is distributed among different computers. So that computational functions can be performed at the same time.
With the help of Remote Method Invocations, the on-demand network model is used in Cloud Computing Systems which provides access to a shared pool of computing resources.
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 that are used for monitoring, accessing and managing infrastructure from a remote location.
Examples – Servers, Firewalls, Routers, CDNs
2) Platform as a service (PaaS)
It provides a line of self-service modules for software developers to manage 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 side.
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 also the IT infrastructure. It provides many benefits for hardware and software, which a few years ago seemed absolutely impossible.
Now a virtual machine just needs a few minutes to run. Cloud Computing has changed the outlook of companies and businesses. It has now become the first choice of everyone because if someone does business with proper planning, strategy and proper budget, then he will definitely get success.
And scientists are doing more and more research to make it better.
Note – The real funda of Cloud Computing is that “you can access any of your data by staying in any corner of the world”, for example, G-Mail, Google Drive, etc.
