Introduction
- Cloud computing is a service, which offers customers to work over the internet. It simply states that cloud computing means storing and accessing the data and programs over the internet rather than the computer’s hard disk.
- The data can be anything such as music, files, images, documents, and many more.
- The user can access the data from anywhere just with the help of an internet connection. To access cloud computing, the user should register and provide with ID and password for security reasons.
- The speed of transfer depends on various factors such as internet speed, the capacity of the server, and many more.
- The management of Cloud Computing is done by the host itself as they come up with new modifications, which continuously improves the service.
- The host has an ample amount of storage and fast processing servers, through which the data gets accessed very quickly. Cloud Computing major advantage is that the user can only concentrate on the job while leaving the problems behind.
What is Cloud Computing?
Cloud computing is the technology in which various types of services are made using the Internet. These services can be whatever it may be, whether it is any kind of software or storage space on the server or any other service.
Cloud computing means providing any type of computing service through the Internet on user demand.
If cloud computing is explained in easy language, then in this technology, the user is provided with the facility of data storage on an Internet server (called cloud), in such a way, by purchasing space on the cloud, the user can save any amount of data on it. And can access and use their data from anywhere in the world.
Examples Of cloud Computing
Many examples of cloud computing technology exist in the world today. Of which we present a few well-known examples.
1.Youtube: Everyday millions of videos are uploaded on the famous video sharing platform youtube, in such a situation, youtube uses cloud computing technology to store so many videos.
2. Facebook: A well-known social media platform like Facebook which has a profile of billions of people and has a lot of data, Facebook also uses cloud computing to keep so much data.
3. Email : All companies providing email services (such as Gmail, Rediff, Yahoo) and all companies with online Stroage space, such as dropbox, mediafire, Microsoft One Drive or Mega, etc. use cloud computing only.
History Of Cloud Compting
At around in 1961, John MacCharty suggested in a speech at MIT that computing can be sold like a utility, just like a water or electricity. It was a brilliant idea, but like all brilliant ideas, it was ahead if its time, as for the next few decades, despite interest in the model, the technology simply was not ready for it.
But of course time has passed and the technology caught that idea and after few years we mentioned that:
In 1999, Salesforce.com started delivering of applications to users using a simple website. The applications were delivered to enterprises over the Internet, and this way the dream of computing sold as utility were true.
In 2002, Amazon started Amazon Web Services, providing services like storage, computation and even human intelligence. However, only starting with the launch of the Elastic Compute Cloud in 2006 a truly commercial service open to everybody existed.
In 2009, Google Apps also started to provide cloud computing enterprise applications.
Of course, all the big players are present in the cloud computing evolution, some were earlier, some were later. In 2009, Microsoft launched Windows Azure, and companies like Oracle and HP have all joined the game. This proves that today, cloud computing has become mainstream.
How Cloud Computing Works?
- Cloud Computing works by providing permission to the user to upload and download the information which stores. We can access the data from anywhere. A user will get the initial amount of storage at a very low price.
- Cloud Computing can be divided into two systems. One is front-end and the other is back-end. The two ends connect to each other with the help of an internet connection.
- The backend of the cloud is the system and the front end is a computer user or client. The front end of the system has the application, which is used to access the cloud system. Moreover, the backend has various computers, hardware, servers, and data storage systems that make the cloud.
- All these features and functions managed by the central server. The central server ensures that everything runs smoothly and in a perfect manner. It is done with the help of software named Middleware, which also permits the network computer to communicate with each other.
Types Of Cloud Computing
Cloud Computing is divided based on two different methods
(A). Cloud Deployment Models .
(B). Cloud Services Models.
(A) Cloud Deployment Models.
1. Public Cloud Computing:
The public cloud is available to everyone and is managed by the service provider. Public cloud services are often free or they are rarely charged. Amazon Web Services (AWS), Microsoft azure are all examples of Public Cloud Computing.
2. Private Cloud Computing
In Private Cloud Computing, services and networks are stored on a private cloud. In this, the user does not have to share cloud storage with any other person. Like Google Drive is the example of a private cloud computing. Here all your data is protected by your email id and password and no one else can use your drive in it.
3. Hybrid Cloud Computing
Hybrid Cloud uses both private cloud and public cloud. Some of the content on a site is available only to the registered people and some of the content is available to the public, then such cloud is called hybrid cloud.
4. Community Cloud Computing
Community Cloud Computing is available only to a group of people. Apart from this, no other outsider can access this data. For example, for a government office, only its employees can use the data available on its site or the content available on the website created by a university can only be used by the students of that university.
(B) Cloud Services Models.
1. Iaas (Infrastructure as a service)
In this type of service, the computing power, storage, software, network power of the cloud and the rest of the control is with the user. This service is basically used for business. The biggest example of this is VPS i.e. Virtual Private Server. In which you get software and network as well as computing power.
2. Paas (Platform as a service)
In Paas (Platform as a service) the user gets only one platform. In which there can be either storage or computing power, in this you do not control things completely, only cloud providers can control them, examples of this are Gmail, Rediff, Yahoo etc.
3. Saas (Software as a service)
In Saas (Software as a service) you get only one software hosted on a remote server which is used for a certain work. These types of services are mostly used by small businesses. This type of service can contain any kind of software such as Google Docs Online or Google G Suite etc. These are all examples of saas.
Advantages Of Cloud Computing
1) Back-up and restore data
Once the data is stored in the cloud, it is easier to get back-up and restore that data using the cloud.
2) Improved collaboration
Cloud applications improve collaboration by allowing groups of people to quickly and easily share information in the cloud via shared storage.
3) Excellent accessibility
Cloud allows us to quickly and easily access store information anywhere, anytime in the whole world, using an internet connection. An internet cloud infrastructure increases organization productivity and efficiency by ensuring that our data is always accessible.
4) Low maintenance cost
Cloud computing reduces both hardware and software maintenance costs for organizations.
5) Mobility
Cloud computing allows us to easily access all cloud data via mobile.
6) IServices in the pay-per-use model
Cloud computing offers Application Programming Interfaces (APIs) to the users for access services on the cloud and pays the charges as per the usage of service.
7) Unlimited storage capacity
Cloud offers us a huge amount of storing capacity for storing our important data such as documents, images, audio, video, etc. in one place.
8) Data security
Data security is one of the biggest advantages of cloud computing. Cloud offers many advanced features related to security and ensures that data is securely stored and handled.
Future of Cloud Computing
No one can tell the future, but we can predict it, by analyzing the current trends and usage. Below, are some prediction about Cloud computing:
1. Increase Storage Capacity
Today, data is generating in a high volume and it’s difficult to store it with security. Most of the companies require a place where they can securely store their data.
So many businesses are adopting cloud computing and it has been predicted that the Cloud providers will provide more data centers at a lower price as there is a large competition between them. With the help of the more in your company will be able to store the data.
2. Enhanced Performance of Internet
With the help of the Internet of Things, the quality of the internet can be increased. With the help of the IoT and Cloud Computing, we can store data in the cloud, for further analyze & provide enhanced performance.
The users expect high-quality fast-loading services and application. The network provided will be faster and the ability to receive and deliver that data will be quick.
3. Modular Software Will Be Priority
The size of an individual program along with the complexity is increasing regularly. This leads to the fact that Cloud technology will soon require advance system thinking.
We can see software development from many angles because in the future applications will store in places other than the cloud. This application will store on different modules, on servers of different Cloud Service.
This can also reduce the cost of software as placing components of the program on different storage is economical.
4. Internet of Things Along With Cloud Computing
The internet of things is also one of the leading Technology is it comes with continuous innovation in real time Data Analytics and cloud computing. There are many machine-to-machine communication, data, and process occurring. We can do it easily with the help of cloud computing.
5. Data Shows How Future Changes
The cloud computing market is growing at 22.8 percent and will exceed $127.5 after 2018. By 2018, 62% of all CRM software will be cloud-based. Moreover, 30% of all application spending is for software as a service based applications.
6. Improvement in Cloud Services
Cloud Computing includes:
- Infrastructure as a service
- Platform as a service
- Software as a service
With this service, we can achieve our desired goals. There are many researchers which have proved that Cloud Computing will be one of the leading technologies in the future as the software as a service solution will account for more than 60% of the workload.
It also has been predicted that the platform as a service and infrastructure as a service will increase gradually as it has been used in most of the organizations. Cloud Computing is user-friendly and is compatible for both new as well as old organizations.
7. Security
The data which are stored in the cloud is secure but not fully. The small companies which are providing cloud services may or may not provide proper security to the data.
So in the future, we can prevent from cyber attacks by providing better security. The cloud providers provide better security measures opening balance ways to prevent cyber attacks.
8. Modular Software
Companies are using much software, which is yet to modify. This leads to the fact that cloud computing requires modified software, which will provide better security and facilities. This software will be more user-friendly and flexible to use.
One of the major advantages of this software will be that it will save the overall cost as well as time. We can see from the below graph, companies providing services and software are also improving.
9. Economic
If cloud computing will continue to evolve the use of hardware will be less as most of the work will be done with the help of cloud computing and virtualization. We can save the setup cost of software by dividing it and this will lead to decreasing the use of hardware.
If the evolution continues the data stored in the cloud will get analyzed with the help of a machine and it won’t require any human help.
Summary of Future of Cloud Computing
Businesses nowadays are seeking innovative ways to grow and accomplish their business goals. With the help of cloud computing, this business will keep on growing in the future. Cloud computing is powerful and expansive and will continue to grow in the future and provide many benefits.
Cloud computing is extremely cost-effective and companies can use it for their growth. The future of cloud computing is bright and will provide benefits to both the host and the customer.
One should keep in mind that the owner of the company should be familiar with the latest development taking place in Cloud technology.
