Cloud computing involves delivering computing services over the internet instead of on local hard drives. It has its origins in the 1950s with mainframe computing and evolved with virtual machines in the 1970s and VPN services in the 1990s. There are different types of cloud including public, private, and hybrid clouds. Cloud services provide software, platforms, and infrastructure as a service and offer benefits like scalability, reliability, and reduced costs but also have disadvantages like potential bandwidth issues and performance impacts.
Cloud Computing
- 2. Cloud Computing Distributed computing on internet Or delivery of computing service over the internet. Instead of keeping data on your own hard drive you use a service over the Internet, at another location, to store your information or use its applications. Cloud services are popular because they can reduce the cost and complexity of owning and operating computers and networks. Cloud benefits to users include scalability, reliability, and efficiency.
- 3. HISTORY "cloud computing" gradually evolved in 1950’s when large-scale mainframes were made available . The real implementation of virtual machines came in the 70s when IBM released an operating system called VM. In the 1990s, telecommunications companies began offering virtual private network (VPN) services with comparable quality of service, but at a lower cost.

- 7. Public Cloud Public clouds are owned and operated by third parties, they deliver superior economies of scale to customers, as the infrastructure costs are spread among a mix of users, giving each individual client an attractive low-cost, “Pay-as-you- go” model. y third parties; they deliver superior economies of scale.
- 8. Private Cloud Private clouds are built exclusively for a single enterprise. They aim to address concerns on data security and offer greater control, which is typically lacking in a public cloud.
- 9. Hybrid Cloud Hybrid Clouds combine both public and private cloud models. With a Hybrid Cloud, service providers can utilize 3rd party Cloud Providers in a full or partial manner thus increasing the flexibility of computing. The Hybrid cloud environment is capable of providing on-demand, externally provisioned scale
- 11. Cloud Computing Services SaaS (Software as a service): Required software, Operating system & network is provided. PaaS (Platform as service): Operating system and network is provided. IaaS (Infrastructure as a service): just Network is provided.
- 13. Saas (Software As a Service ) We can access this cloud hosted application without any additional hardware or software. E.g. : G-mail, Yahoo mail, Hotmail etc.,
- 14. Paas (Platform As a Service ) Give us nice API (Application Programming Interface) and take care of the implementation. It is a platform for developers to write and create their own SaaS. i.e. applications.
- 15. Iaas (Infrastucture As a Service ) It is also known as hardware as a service. Iaas is a computing power that you can rent for a limited period of time. allows existing applications to be run on a cloud suppliers hardware.
- 16. ADVANTAGES Software as a Subscription Reduced Software Maintenance Increased Reliability Environmentally Friendly Cost Reduction Portability/Accessibility
- 17. DISADVANTAGES Bandwidth could bust your budget App performance could suffer Data might not be cloud-worthy Too big to scale
- 18. Conclusion Cloud Computing is the fastest growing part of IT. Tremendous benefits to customers of all sizes storage space. Cloud services are simpler to acquire and scale up or down
- 19. conclusion Public clouds work great for some but not for all applications. Private clouds offer many benefits for internal applications. Public and private clouds can be used in combination.
- 20. Real Time Application Google -Network Made up of millions of servers, which stores amounts of data. Amazon’s Elastic Compute Cloud-Amazon It provides resizable computing capacity on cloud, Developer’s only pay for capacity they use.
