What is Cloud Computing?
In today’s time, the number of computer and mobile users is continuously increasing. Due to which data storage is being given priority in all areas. All types of business whether small or big spend money. Apart from this, it also requires IT support and storage hub. Because of which all types of businesses are not able to spend so much money for IT infrastructure and support. In its place, cloud computing is a cheap and very good option.
Due to easy computation, data can be protected more efficiently in cloud computing. Due to which big businesses are also getting attracted towards cloud computing. Cloud computing requires very little hardware and software for the user. For this, the user should only use cloud computing system and interface software. Which is as easy as running a web browser. Banky work is managed automatically by the cloud network. We all have used cloud computing at some time, many companies which are providing cloud computing services like Google. Facebook. Amazon etc.
When using the e-mail service, our data is stored on the cloud server and not on the computer. We do not see the technology and infrastructure used in cloud systems because it is built using HTTP, XML, Ruby, PHP and other similar technologies. The user can connect the cloud system to his computer laptop or mobile quite easily.
Benefits of Cloud Computing
Due to the low cost, many business organizations use cloud computing services, in addition, in cloud computing, the user uses the service as per his needs and pays only for the services used. Cloud Computing has the following advantages:
- Low cost of IT infrastructure
- Less computer hardware and software required
- Better performance
- Less maintenance problems and minimum maintenance cost
- Ease of software update
- Compatibility between cloud computing systems and computer operating systems
- Backup and recovery
- Increase data security
Types of Clouds
There are four models of cloud systems and the user can subscribe to any model as per their business requirements.
In this, cloud computing resources are used for a particular business organization.
This system is mainly useful for intra business in which computer resources are controlled and operated under a single organization.
In this, computing resources are provided to the community and organization.
Public cloud is commonly used in B2C (Business to Consumer) business. In this, computer resources are operated and controlled by government, academy and business institutions.
Hybrid Cloud This type of cloud is used only in both B2C and B2B businesses. This type of cloud system is called “Hybrid Cloud” in which computing resources are connected to different cloud.
Cloud Computing Services
Cloud mainly offers three types of services –
- Software as a Service (SaaS)
- Platform as a Service (PaaS)
- Infrastructure as a Service (IaaS)
Different types of businesses use these services as per their requirement.
SaaS (Software as a Service)
SaaS or software as a service is the “software service distribution” model of cloud computing in which applications are hosted by the service provider or vendor and made available to customers on the Internet. SaaS becomes a very popular service delivery model in today’s times Is going on which supports Service Oriented Architecture (SOA) or Web Services. Through the Internet, this service is made available to customers all over the world.
If we talk about the old way of data storage in which the user had to buy the software to store the data, then he had to install it on his computer. Instead, in this new model, the user can easily subscribe to the cloud service on a monthly basis. You can take advantage of the service, in addition, users can easily use SaaS service on almost all internet enabled devices.
PaaS (Platform as a Service)
It provides such a platform to the developers where they can build or build the application, this service can be hosted in the cloud itself and the user can access it from anywhere through internet.
For example, just like teachers provide paint colors, paper, brushes, etc. for children to draw, students just have to do painting, similarly in PaaS the user is provided with a platform with different tools where he can give the application Can develop. Here new features are updated for the users from time to time. It provides a platform that supports application development, thus it is very beneficial for software developers, web developers and other businesses, besides software support and management services, storage, networking, deploying, testing, collaborating, hosting. The facility of and applications are also available.
IaaS (Infrastructure as a Service)
Apart from PaaS, IS is a fundamental service of cloud computing. In this, the user can access computing resources on the Internet in a virtual way. It provides various types of computing services and infrastructure like virtual server space, network connections, bandwidth, load balancers and IP addresses etc. In this, the networks are usually divided into free data centers and in it hardware resources also work on a lot of services.
IaaS is a complete package of computing. It is very suitable for small scale business as it has relatively lower cost of IT infrastructure. By using IaaS computing, any business can save a lot of costs such as maintenance, buying new components like -hard-drives, network connections, external storage device etc.
- In cloud computing, data can be protected in a more efficient way.
- Cloud computing requires very little hardware and software for the user.
- Google. Facebook. Amazon etc. The company is providing cloud computing service to the user.
- We do not see the technology and infrastructure used in cloud systems because it is built using HTTP, XML, Ruby, PHP and other similar technologies.
- The user can connect the cloud system to his computer laptop or mobile quite easily.
- There are four models of cloud systems – Private Cloud, Community Cloud, Public Cloud, Hybrid Cloud
