Overview of cloud computing?

Cloud computing*

Computing in which dynamically scalable and often virtualized

resources are provided as a service over the Internet/Intranet”.

Five characteristics of cloud computing

1. On-demand self-service

2. Ubiquitous network access

3. Location independent resource pooling

4. Rapid elasticity

5. Pay Per Use

Cloud delivery models**

1. IaaS

2. PaaS

3. SaaS

4. Praas

Cloud deployment models**

1. Public clouds

2. Private clouds

3. Community clouds

4. Hybrid clouds

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 School

Harvard’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—17,481

non-searchable PDF pages—into a searchable database within 24 hours.

• The New York Times

New York Times used Amazon EC2 to convert full page images of its newspapers from 1851 to

1922 into PDF using Amazon EC2

• Virgin Atlantic’s Vtravelled.com

To celebrate the 25th anniversary of Virgin Atlantic Airways, the company announced their new

travel website, Vtravelled.com. Just like their planes, their new site is in the clouds, hosted entirely

on 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 on

the 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 2,000

employees 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 the

tools/utilities that they are used to from the on-premise world.

• Enterprises are testing cloudy-waters by deploying B2C standalone

applications

• 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?

Page 14: Raghu Cloudcomputing

Challenges faced

• Capacity planning and SLA management

• Vendor viability (CogHead scenario?)

• Lots of unknowns

– Data location - Does it comply with your regulatory requirements

– Data loss - What is the back-up/restoration procedure followed

– Data Security - The procedures followed to protect the data

– Data clean-up after discontinuation of service

• Lack of widely adopted Standards

– IaaS - Virtual machine templates (OVF)

– IaaS - Uploading, downloading, inspecting, configuring, and performing

actions like spinning new instances (OCCI)

– IaaS/PaaS - Machine Data and code portability

– PaaS – Choose a framework offered by multiple providers and avoid

provider specific extensions

Cloud computing must move away from merely

being 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?
