Simple Introduction to Cloud for Users
This document discusses using cloud computing in organizations. It describes how cloud computing provides massive processing power, storage, security, availability, and scalability at lower costs than maintaining physical infrastructure. The cloud allows organizations to start small and grow infrastructure on demand. Three common cloud service models are introduced: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). The cloud enables new ways of working and playing through ubiquitous access to computing resources and data from any device.

- 2. New Demand forIT infrastructure Capacity Massive processing power Massive Storage Security Availability Scalability Start small and grow on demand Cost effective
- 3. New Challenges High operatingcost Man power cost Equipment cost Energy cost High operating complexity Changing technology Increase complexity Network, server, storage , security
- 4. Dream machine Computer withinfinite capacity Start small and grow big based on my demand Capacity can scale up and down on demand Pay only what we use. No complex operating and maintenance
- 5. It is called cloud computing system
- 6. What is CloudingComputing? • A style of computing in Cloud which dynamically scalable and often virtualized computing resources are provided as a service over the Internet. Google Saleforce Amazon Source: Wikipedia (cloud computing) Microsoft Yahoo

- 10. Why we shouldmove to the cloud? Quick start up no need to purchase any equipment. Subscribe, pay, and use it. Scalability less demand less computing power, more demand more computing power Elasticity Handle the demand surge Less maintenance No need to hire people to fix server broken, hacking, tuning Less operation cost Pay only what you really use Cut the cost of maintaining huge infrastructure It is cool, trendy Just a stupid execute when people do not believe you ^_^

- 13. Using IaaS Cloud Userview the cloud as a number of servers Look the same as co-location server This is actually a virtual server Windows or many flavor of Linux User can start stop and reboot from web interface Normal web based application work fine Usage is charge on pay per use Can try at aws.amazon.com Open a new account and start a new server use less than 30 minutes to apply
- 14. Using PaaS Cloud PaaScloud give you an API to program on the cloud There is a need to port application etc. .NET to Windows Azure Python to google app engine Pros and Cons More light weight that IaaS but need some application porting effort

I have no need to install mail client, maintain mail server
- 22. Work Life witha Cloud Document (google docs) I can create basic document, good spreadsheet, basic presentation without installing any software I can down load document and edit it on my computer I can share my document with other on internet and edit it together Storage (google drive, dropbox) Create presentation on notebook, drop in in dropbox Present from iPad, Smartphone Secure, no need to carry thumb drive Easily share file with other people making team work easy
- 24. Play Life witha Cloud Picture Using Instagram, photo, video I take instantly appear on twitter and facebook and neatly catalog Picture can be shared, tag, comment among my 2000 friends on facebook! If I want, they will know where I was. (Little dangerous) Communication My thought can be spread anytime anyway using facebook, googleplus, multiply I can even “hang out” with friend on google plus
- 25. Play Life witha Cloud Book Amazon Kindle Store. Buy book from amazon and they will keep it on their cloud Unlimited book shelves, no cleaning, dusting Read your book on any device iPad, iPhone, Androiod Phone, Tablet, PC, Mac I read mine on iPad, and my Galaxy S2 phone
- 26.

Moving KU ComputerEngineering on the Cloud Introduction Department of Computer Engineering is one of the leading computer engineering in Thailand (23 years) Research and Education 30 faculty member 20-30 Ph.D students 50 Master, 120 MSIT, 400 Undergrad Mission Must support the teaching and research by providing server / network/ service infrastructure Driving toward mobile anytime anywhere infrastructure
- 28. Moving KU ComputerEngineering on the Cloud Challenge and Opportunity Must provide a scalable and reliable infrastructure Servers, Storage Services Previously, a number of physical server has been used Getting old quickly, hard to maintain, a lot of space Consume a lot of power, cooling
- 29. Moving KU ComputerEngineering on the Cloud Cloud is Solution For Server, use VM cloud (VMware) to consolidate all small server into a set of VM on only 5 machines Every lab, professor can request for VM for their use Can scale easily using more physical server Moving to centralize large storage using NAS/SAN storage cloud

- 31. Cloud computing openissues People do not trust other to have their important data And why people trust your bank to have all their money? People do not trust that cloud provider can provide a robust and secure environment How many time your system went down or being hacked compared to google or facebook? Do avrage company have better staff than ISP who deal with these problems on a daily basis Interesting!
- 32. Conclusion Cloud Computing ishere! You are using it everyday SaaS Level such as facebook, gmail Let fly above the cloud and see what it can do for you.
