Cloud computing refers to provisioning computational resources like applications and storage over the Internet. It allows users to access software from anywhere without installing it, and shares computer resources between users. Key benefits include reduced costs since users pay based on usage, increased access via any Internet-connected device, improved security from data distribution, high reliability, and easy maintenance of up-to-date applications without user downloads. Common cloud services are SaaS, PaaS, and IaaS, providing software, development platforms, and basic infrastructure respectively.

10. Only need is High-Speed Internet. Key Features1- CostGreatly reduced Cost on purchasing diff kinds of Software , operating system etc.

11. No need to be purchased for one-time or infrequent computing tasks.

12. Pricing of any services is compute on usage-based options

13. Fewer IT skills are required for implementation (in-house) . 2- DeviceLocation independence enable to access systems using web browser

14. Regardless of their location or device they are using (e.g. PC, mobile).

15. Accessed via the Internet, users can connect from anywhere. 3- Security Improve due to a specialized company taking care of the data

16. Security is greatly increased when data is distributed over a no. of devices & Area Key Features4- Reliability Utilization and efficiency improvements for systems that are often only 10–20% utilized.

17. Suitable for Business continuity and disaster recovery.

18. IT and business managers can at times do little when they are affected.5- Maintenance Applications are easier to maintain, since they don't have to be installed on each user's computer.
