The service offered through the internet to the users on-demand rather than by the company’s own servers is called cloud services. The data is stored in pools or digital servers and is available any time through the internet. Cloud services refer to any applications, services or resources. The service is managed by the cloud service provider. The provider provides all the resources needed for the application and hence the company needs not to worry about resource allocation. Cloud services can dynamically scale up based on users’ needs. We can say that the cloud is the delivery of servers, storage, and backups online. Service providers charge companies for cloud usage.
The data can be stored online and also backed up, documents can collaborate easily, database processing can be done and technical support services can be managed. Also, new applications can be created and managed, data is recovered and streaming audio and video, data analysis, and prediction are done using cloud services. Users’ activity is tracked easily using cloud and hence it is made secure.
The idea of cloud started in the 1950s. By the beginning of the 1990s, cloud services were used by everyone due to the IT revolution. Cloud service provision started only by 2000. The advancement in the cloud grows day by day. All the organizations, irrespective of size use cloud services. Due to the new features such as customer relationship management, data management, delivery applications, enterprise resource management, industries use cloud services in all forms.
Now the applications need not be downloaded in the system to use. Cloud infrastructure helps the organizations to use applications at their own pace and with no license issues. Hence the storage and time of download are saved. Also while using the application in the cloud, the application works faster than the local network. The advantages of cloud services are scalability, accessibility, speed, less cost, automatic update, patch updating, data recovery, security, less power, no physical servers in the organizations and collaboration of storage with different enterprises.
