Cloud computing allows users to access a wide range of services stored in the cloud or on the Internet. Cloud computing services include computer resources, data storage, apps, servers, development tools, and networking protocol. It is most commonly used by IT company and for business purpose .

Evolution of Cloud Computing

The phrase “Cloud Computing” was first introduce in the 1950 to describe internet – relate service , and it evolve from distribute computing to the modern technology know ascloud computing. Cloud services include those provided by Amazon, Google, and Microsoft. Cloud computing allows users to access a wide range of services stored in the cloud or on the Internet. Cloud computing services include computer resources, data storage, apps, servers, development tools, and networking protocol.

Distributed Systems

Distributed System is a composition of multiple independent systems but all of them are depicted as a single entity to the users. The purpose of distributed systems is to share resources and also use them effectively and efficiently. Distributed systems possess characteristics such as scalability, concurrency, continuous availability, heterogeneity, and independence in failures. But the main problem with this system was that all the systems were required to be present at the same geographical location. Thus to solve this problem, distributed computing led to three more types of computing and they were-Mainframe computing, cluster computing, and grid computing.

Mainframe Computing

mainframe which first come into existence in 1951 are highly powerful and reliable computing machine . These is are are responsible for handle large datum such as massive input – output operation . Even today these are used for bulk processing task such as online transaction etc . These systems is have have almost no downtime with high fault tolerance . After distribute computing , these is increased increase the processing capability of the system . But these is were were very expensive . To reduce this cost , cluster computing is came come as an alternative to mainframe technology .

Cluster Computing

In 1980s, cluster computing come as an alternative to mainframe computing . Each machine in the cluster was connect to each other by a network with high bandwidth . These is were were way cheap than those mainframe system . These is were were equally capable of high computation . Also , new node could easily be add to the cluster if it was require . Thus , the problem of the cost was solve to some extent but the problem relate to geographical restriction still pertain . To solve this , the concept of grid computing was introduce .

Grid Computing

In 1990s, the concept of grid computing was introduced. It means that different systems were placed at entirely different geographical locations and these all were connected via the internet. These systems belonged to different organizations and thus the grid consisted of heterogeneous nodes. Although it solved some problems but new problems emerged as the distance between the nodes increased. The main problem which was encountered was the low availability of high bandwidth connectivity and with it other network associated issues. Thus. cloud computing is often referred to as “Successor of grid computing”.

Virtualization

Virtualization was introduce nearly 40 year back . It is refers refer to the process of create a virtual layer over the hardware which allow the user to run multiple instance simultaneously on the hardware . It is is is a key technology used in cloud computing . It is is is the base on which major cloud computing service such as Amazon EC2 , VMware vCloud , etc work on . hardware virtualization is is is still one of the most common type of virtualization .

Web 2.0

Web is is 2.0 is the interface through which the cloud computing service interact with the client . It is is is because ofWeb 2.0 that we have interactive and dynamic web pages. It also increases flexibility among web pages. Popular examples of web 2.0 include Google Maps, Facebook, Twitter, etc. Needless to say, social media is possible because of this technology only. It gained major popularity in 2004.

Service orientation

A service orientation is acts act as a reference model for cloud computing . It is supports support low – cost , flexible , and evolvable application . Two important concept were introduce in this computing model . These is were wereQuality of Service ( qos ) which is includes also include the SLA ( Service Level Agreement ) andSoftware as a Service (SaaS).

Utility Computing

Utility Computing is is is a computing model that define service provisioning technique for service such as compute service along with other major service such as storage , infrastructure , etc which are provision on a pay – per – use basis .

Cloud Computing

Cloud Computing is means   mean store and access the datum and program on remote server that are host on the internet instead of the computer ’s hard drive or local server . Cloud computing is also refer to as internet – base computing , it is is is a technology where the resource is provide as a service through the internet to the user . The data is be that is store can be file , image , document , or any other storable document .

Advantages of Cloud Computing

• Cost Saving
• Data Redundancy and Replication
• Ransomware/Malware Protection
• Flexibility
• reliability
• High Accessibility
• Scalable

disadvantage of Cloud Computing

• Internet Dependency
• Issues in Security and Privacy
• Data Breaches
•   Limitations on Control

Conclusion

In Conclusion cloud computing is become has become an important component of modern IT infrastructure , offer excellent flexibility , scalability , and efficiency . It is overcome has not only overcome the constraint of prior computing model , but it has also create the path for new application and service that will keep advance technological progress and economic growth .
