  1. Cloud Computing Cory Willing Computer Science University of Wisconsin-Platteville November 24, 2009

  2. Explanation of Technology • Usage-based computing • Term refers to “cloud” concept of Internet • Data and software stored on remote server • Accessed via web browser or other system on client's computer • Each server holds multiple virtual machines for different software • User is charged for access to software and data

  3. Explanation of Technology (cont.) • Differences from Grid Computing • Grid computing uses power of distributed PCs to achieve a common goal • SETI@home • Cloud computing uses server to provide for thousands of clients Figure 1: Search trends of Google for 2008, with Cloud Computing outpacing Grid Computing

  4. Hurdles in Development • How long will data be maintained? • How can customers be insured against service outages or data loss? • How will users switch data from one provider to another? • How will providers handle hosting proprietary software?

  5. Hurdles (cont.) - Security • Internet is not a safe medium as of right now • Cloud computing may not be an option for hospitals, government institutions, etc. • Possible solutions: • Encode information before sending it across cloud (SSL/TLS) • Private cloud for large companies: provider and client protected by firewall

  6. Major Players • Google • Google Docs • AppEngine • Used to create web applications to be used in cloud computing • Scales easily, but does not allow programmer much freedom

  7. Major Players (cont.) • Microsoft • Azure • Programmers can choose almost any language • Most applications supported • Scales somewhat easily • Programmer enjoys modest amount of freedom

  8. Major Players (cont.) • Amazon • Elastic Compute Cloud • Programmers have control of almost entire system • Supports virtually every language • Treats each VM as though it were an independent machine • Major issues with scalability

  9. Future • Up-to-date software: Client does not need to find patches for programs • Truly portable access points: • Laptops, cell phones, Blackberries, etc. • Small businesses will have access to IT benefits previously enjoyed only by large corporations

  10. Future (cont.) - Brokers • Brokers buy large shares of computing power from multiple providers • When a client needs quick, temporary access to a program, she goes to the online marketplace • Brokers try to outbid each other for contracts with providers • At the same time, brokers must provide users with lowest-cost service

  11. Future – Brokers (cont.) Figure 2: Brokers vie for customers in an online marketplace for computing resources

  12. Conclusion • Cloud computing is in its infancy • Many hurdles to overcome • Which industry giant will lead? Will there be one leading company? • Set to be the next revolution in computing
