Cloud computing refers to delivering computing services such as databases, software, storage, and computing power over the Internet. It evolved from earlier technologies such as remote job entry in the 1950s and Amazon launching the first public cloud, AWS, in 2006. There are different types of cloud computing based on deployment and usage including public, private, hybrid, and external clouds. Key characteristics include on-demand self-service, shared resources, massive scale, and pay-per-use. Common cloud service models are infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS).

- 2. INTRODUCTION Cloud computing refers to both the applications delivered as services over the Internet and the hardware and system software in the datacenters that provide those services. Cloud computing is an Internet ("cloud") based development and use of computer technology ("computing"). With Cloud computing users can access database resources via the Internet from anywhere.
- 3. HISTORY Concept evolved in 1950(IBM) calledRJE (Remote Job Entry Process). In 2006 Amazon provided First publiccloud AWS(Amazon Web Service).
- 4. What is Cloud Computing? Distributed computing on Internet or delivery of computer services over the internet. Eg:Gmail,Yahoo,Hotmail Instead of running email program on your computer you login to a web email account remotely. The software and storage for your account doesn’t eist on your computer.
- 5. How to Implement cloud computing? Open source software has provided the foundation for many cloud computing implementations. The cloud computing environment can consist of multiple types based on their deployment and usage. Types Public clouds Private clouds Hybrid clouds External clouds
- 6. Architecture The two most significant components of cloud computing architecture are known as the front end and the back end. The front end is the part seen by the client, i.e. the computer user.
- 7. Layers of the cloud Client Application Platform Infrastructure Server
- 9. SERVICE MODELS Cloud computing providers offer their services according to three fundamental models: Infrastructure as a service (IaaS) Platform as a service (PaaS) Software as a service (SaaS)
- 10. Variations of cloud computing Clouds can be classified as: Infrastructures Platforms Applications
- 11. Types and vendors of cloud computing services Types of cloud computing Simplest form More complex form
- 13. MORE COMPLEX FORM 1. Web–based office application. Online photo and document sharing Eg: ZOHO Work Online, Live Mesh 2. Branded, Domain-wide web service. Hosted spam filtering Eg: postini, Google apps, Microsoft Office Live Beta 3. Large-scale web-based storage and computing power for building your own application. Eg: Amazon web services, Google app Engine
- 14. Advantages and disadvantages • Lower software cost • Improve performance • Fewer maintenance issue • Instant software updates • Increased data safety Advantages • Requires a constant internet connections • Doesn’t not work well in low speed connections • May be slow • Limited features Disadvantages
- 15. Conclusions Cloud computing increases profitability by improving resource utilization. Costs are driven down by delivering appropriate resources only for the time those resources are needed. Cloud computing has enabled teams and organizations to streamline lengthy procurement processes.
