This document provides an overview of cloud computing. It discusses how cloud computing allows users to access computer resources over the internet without direct management. The history and evolution of cloud computing from the 1950s to present day is examined. The document outlines the architecture and features of cloud computing including on-demand access, scalability, and availability. It also discusses the different types of cloud computing models and services. The advantages and disadvantages of cloud computing are presented. Two case studies on how cloud computing has helped organizations are provided. Security issues related to confidentiality, integrity, availability and privacy in cloud computing are explored along with potential solutions.

- 1. CLOUD COMPUTING SUBMITTED TO: SUBMITTED BY: DR.DERMINDER SINGH RACHNA KUMARI (ADVISOR) MCA-II L-2018-AE-05-MCA
- 2. INTRODUCTION: • CLOUD COMPUTING IS THE ON-DEMAND AVAILABILITY OF COMPUTER SYSTEM RESOURCES , ESPECIALLY DATA STORAGE AND COMPUTING POWER ,WITHOUT DIRECT ACTIVE MANAGEMENT BY THE USER. • CLOUD COMPUTING IS THE DELIVERY OF DIFFERENT SERVICE THROUGH THE INTERNET.
- 3. HISTORY: 1950 The Cloud Computing concept came into the picture with accessible via thin/static clients and the implementation of mainframe computers. 1961 John McCarthy delivered a speech at MIT in which he suggested that computing can be sold like a utility like electricity and food. 1999 Salesforce.com became the 1st company to enter the cloud arena to provide enterprise-level applications to end users through the Internet. Amazon came up with Amazon Web Services, providing services like computation, storage. Google Apps and Microsoft’s Windows Azure also started to provide cloud computing enterprise applications. 2002 2009
- 6. TYPES OF CLOUD COMPUTING: HYBRID CLOUD PUBLIC CLOUD PRIVATE CLOUD
- 7. TYPES OF CLOUD COMPUTING SERVICES: • INFRASTRUCTURE AS A SERVICE(IAAS) • PLATFORM AS A SERVICE(PAAS) • SOFTWARE AS A SERVICE(SAAS)
- 8. Advantages : 1.COST SAVING 2.HIGH SPEED 3.BACKUP AND RESTORE DATA 4.RELIABILITY 5.UNLIMITED STORAGE 6CAPACITY
- 9. DISADVANTAGES: DOWN TIME 1.DOWN TIME 2.TECHNICAL ISSUES 3.INTERNET CONNECTIVITY 4.LOWER BANDWIDTH 5.SECURITY THREAT IN THE CLOUD
- 10. CASE STUDY ON CLOUD COMPUTING : IRCTC Online Tatkaal Ticket Booking from 10 Am To 12 Pm in India (NEED OF CLOUD COMPUTING) • For tatkaal ticket booking in india, for booking of ticket in peak hours is 10 times higher than the rest of the day. • The site of IRCTC www.irctc.co.in hits by users in 49 transaction/second and GOOGLE hits by users 42000 transaction/second • IRCTC has a locking mechanism means one seat can not allotted to other people but GOOGLE can share same information to different peoples. Then how we manage these transactions, IRCTC provided a temporal solutions by barring agent login at peak times but it is not good approach. • Other solution is that adding more thousand servers but buying these servers is very tough for companies which is already in tight budget. • For some big companies if they buy thousand servers, but for managing peak hours traffic buying these servers is not right approach. • So there is a need of cloud computing who can manage fluctuations.
- 11. Providing Aadhar Card to Every People of India • Bank account holders in india is 20% and large no. of peoples have their no identity. • Providing aadhar card to 800+ billion peoples is a major project. • Then this project may lead to no. of bank accounts,no. of debit cards/credit cards in rural areas. • Then managing these things is obviously need of cloud computing. Security Issues in Cloud Computing Main issues in cloud computing is related to security.we shows some security issues in cloud computing.
- 12. Security Issues in Cloud Computing Confidentiality In the case of cloud computing environment, confidentiality means how we secure our data from cloud providers as well as other customers. customers outsourced their data on cloud servers which is managed by untrustworthy cloud providers. Outsourced means customers loss their physical control over data. Integrity Integrity means data should not be modified or alterd. data are honestly stored on cloud servers. and data should not be modified by cloud providers. if any fault occur then it will be detected as soon as possible. Availability If we are looking for on demand service then it should be present. If the on demand service is no longer available, customers will not believe in cloud system. Privacy Privacy means information should not be shared with others like personal information. data are distributed on cloud servers which are managed by cloud provider then there are issues related to privacy. business competitors want their data should be confidential and does not leak in public markets.
- 13. Solution of these Issues Threats for Confidentiality: in the IaaS service some attacks arises in amazon elastic compute cloud(EC2) like data tampering and side channel attacks(VM to host or host to VM) and network evesdropping. For side channel attacks we need to add a VM on physical server machine. Solution for Confidentiality: for solutions we need some defensive strategies • Trusted cloud computing plateform • Putting data control back to customer Threats for Integrity: in the cloud integrity some threats occurs like data modification • wrong computation on cloud servers • connection pooling and open direct Solutions for In Threats for Availability: the threats is done at service level agreement which is listed as: • denial of service • spoofing • dictionary attack
- 14. Future scope: •A cloud allows users to access application, information, and data of all sorts on an online level rather than by use of actual hardware or devices. •A company offering reliable cloud technology allows for computing to be done in a much more shared way, as a cloud provides a service rather than a product. •Users get and share their information in a way that can allow them to access and give access to the whole world or any groups of people within their cloud. •Cloud computing can open a whole new world of jobs, services, platforms, applications, and much more.
