Overview of cloud computing?

Cloud computing*

Computing in which dynamically scalable and often virtualizedresources are provided as a service over the Internet/Intranet”.

Five character ist ics of cloud comput ing

1. On-demand self-service

2. Ubiquitous network access3. Location independent resource pooling

4. Rapid elasticity

5. Pay Per Use

Early adoption of cloud computing (1/2)

• Animoto, which creates videos for consumers and corporations, uses Amazon EC2 and S3 to

manage gigantic spikes in usage (e.g. going from 70 servers to 8,500 servers in 5 days).

• Harvard Medical SchoolHarvard’s Laboratory for Personalized Medicine (LPM) uses customized Oracle AMIs on Amazon

EC2 to run genetic testing models and simulations.

• Washington Post

The Washington Post uses Amazon EC2 to turn Hillary Clinton’s White House schedule—17,481non-searchable PDF pages—into a searchable database within 24 hours.

• The New York TimesNew York Times used Amazon EC2 to convert full page images of its newspapers from 1851 to1922 into PDF using Amazon EC2

• Virgin Atlantic’s Vtravelled.comTo celebrate the 25th anniversary of Virgin Atlantic Airways, the company announced their newtravel website, Vtravelled.com. Just like their planes, their new site is in the clouds, hosted entirelyon the Amazon Web Services.

Early adoption of cloud computing (2/2)

• NASDAQ Market Replay provides a NASDAQ-validated replay and analysis of the activity in the

stock market. The application is built using the Adobe Flex and AIR platform, and utilizes the Amazon Simple Storage Service (S3) for persisting historical market data

• BNP Paribas is using an on-demand computing service from IBM to run its risk application.

• NedBank Using CloudBurst the bank’s IT department can now provision the environment overnight,the results are available in the morning, the IT staff checks a couple of things, ensure that it’s all OK

and get back onto the project work

• First Bank in Louisville wanted to deliver lender and cash-management support products based onthe software as a service model; they quickly leapt on the nascent cloud concept

• SunTrust late last year rolled out a new relationship-management application to more than 2,000employees in 77 days. Once up on the cloud, SunTrust had a better view of client data, giving it a

better handle on which accounts were profitable and which weren't.



Trends from the early adoption of cloud computing

• Private clouds find favor among data-center folks, PaaS with the developer

community and SaaS/PraaS with the business community• SMEs are the early adopters IaaS

– IaaS provides an easy and low-cost way to test a start-up’s ideas

• ISVs are looking for mature PaaS options, but are finding it way short of thetools/utilities that they are used to from the on-premise world.

• Enterprises are testing cloudy-waters by deploying B2C standaloneapplications

• SaaS is the most easily adopted category

– Salesforce.com, Office

• Virtualized Desktop Infrastructure

• Security conscious early adopters are setting-up private clouds – Consolidation Abstraction Automation Utility Market

• Strong resistance to re-engineering applications for clouds

– Applications that choke at database level?

Cloud computing must move away from merelybeing a low-cost IT delivery model

• An organization might provide a core set of assets/features, that can be used by other

organizations to write and run applications (Value-added-services, VAS) – Facebook revolutionized this concept in social networking

– Telecom industry has adopted this widely

• Can industry functions be generically characterized?
