Cloud computing is the method of using all computing vigor as per the requirement of computer systems and resources online through the Internet without the direct active control of the user.
Suppose we try to understand it in detail. In that case, Cloud computing is a service in which all types of computer hardware, software, and other computing resources are kept online with complete security and responsibility in a separate location by a service provider.
Through the Internet, all the computing services and resources are provided on rent from large organizations in the entire network to a simple user sitting remotely.
For example, Google Drive is provided by Google, has the facility of Cloud Storage and Google Docs, Google Slides, Google Drawings, Google Forms, etc. In which we get the facility to create many types of application-based files, this is cloud computing. We do not need to have any application software on our computer, only an internet browser and a good high-speed internet connection are required.
Whether it is a matter of using large software or storing data, all these cloud computing services are being provided online by big companies such as Google, Microsoft, Amazon, Adobe, etc.

Cloud Computing Architecture
Today all organizations, big and small, are using cloud computing. The cloud can be accessed from anywhere through the Internet, and organizations are taking full advantage of this. Today cloud has taken a big form in the world of the Internet.
Cloud computing is a combination of two technologies, service-oriented architecture and event-driven architecture.
Cloud computing is divided into two parts
- • Front End
- • Back End
Meaning of front end which is visible to a user (client) through which the user can interact with the cloud. In which the front end of the cloud is used by the client (user). The client-side interfaces of the cloud can contain any application or software of the cloud, in which the client uses many features of the cloud.
Cloud Front End interfaces include web servers (including Chrome, Firefox, internet explorer, etc.) that you can easily access from any mobile, computer, or other device devices.
Applications of Cloud Computing
File storage: We use cloud computing to store data online in the cloud. And we can access and update this data whenever we want.
It is straightforward to store data in the cloud. And its cost is also very less, and the security is also better in it.
Video making and editing software
There is much such software that we can access through the cloud. We can use this software to create and edit videos.
These videos are stored in the cloud itself and can be accessed at any time.
File converts: There is much such software, with the help of which we can change the format of any file. For example – HTML can be converted to pdf or jpg to png.
This software is in the cloud. And we can access it anytime from anywhere through the Internet.
Backup & recovery
We use cloud computing for backup. We can back up any files and data in the cloud. And its security is also good.
If ever the data is deleted or destroyed, it can also be recovered.
Features of cloud computing
Cloud computing boasts many attractive benefits for businesses and ends users. Some of the main advantages of cloud computing are:
Cost savings: Using cloud infrastructure can reduce costs, as organizations do not have to spend huge amounts of money to buy and maintain equipment. This lowers their capital expenditure costs – as they do not have to invest in building hardware, facilities, utilities,, or large data centers to accommodate their growing businesses.
Since downtime rarely occurs in cloud computing, companies do not have to spend time and money fixing any downtime problem.
Mobility: Storing information in the cloud means users can access it anywhere, from any device with just an Internet connection. In addition, cloud vendors provide all upgrades and updates automatically, saving you time and effort.
Disadvantages of Cloud Computing
Despite the obvious benefits of relying on cloud services, cloud computing carries its own challenges for IT professionals:
Cloud Safety – which is often considered to be the biggest challenge facing Cloud Computing. When relying on the cloud, organizations run the risk of data breaches, hacking of APIs and interfaces, compromised credentials, and authentication issues. In addition, there is a lack of transparency about how and where sensitive information entrusted to a cloud provider is handled.
Cost Management: Pay-as-you-go subscription plans for cloud usage, coupled with fluctuating workloads, can make it difficult to define and estimate final costs.
Lack of resources and expertise: With the rapid advance of cloud-support technologies, organizations are struggling to meet the growing demand for tools and employees with the appropriate skill sets and knowledge.
IT Governance – Cloud Computing can make IT governance difficult, as there is a need for infrastructure operations
