This document defines cloud computing and outlines its key characteristics. Cloud computing provides on-demand access to shared computing resources like networks, servers, storage, applications and services over the internet. Users can access these resources from anywhere without needing to manage the physical infrastructure. The cloud offers advantages like flexibility, scalability, device independence and reduced costs compared to maintaining physical servers. However, security, vendor lock-in and reliance on a stable internet connection are challenges to cloud computing adoption.

3. What is a cloud ?? Abstraction- Use something without knowing what is going on inside.- Users are shielded from the details how something actually works.

4. An example of abstraction… Key

5. Steering wheel

6. Gearshift

7. Gas pedal

8. BrakesWe seldom worry about the thousands of highly specialized parts that are combined to produce the car…!

9. Cloud !!A Cloud depicts the Internet in computer network as an abstraction of the underlying infrastructure it represents.

16. Three layers to cloud computing…Companies use these layers differently based on what they offer.

30. Scalability !!

32. INSTANT !!

33. How does it work ???No need of running heavy servers and maintaining them.

34. Instead, run applications on a shared data centers.

35. Just plug in to the shared data servers just like using a utility.

36. Its fast to get started and costs less.When using any application in the cloud, the client just needs to log in to his account; just like any other application and access his resources!!

40. Types of CloudsPublic

41. Resources are dynamically provisioned on a self-service basis.

42. Provided by an off-site third-party provider who shares resources and bills utility computing basis.

43. Private

44. Capitalise on data security, corporate governance, and reliability concerns.

45. Users "still have to buy, build, and manage clouds“

46. lacks the economic model that makes cloud computing such an intriguing concept.

47. Hybrid

48. A hybrid cloud environment consists of multiple internal and/or external providers.
