What is Cloud Computing?

“Cloud Computing is a paradigm in which information is permanently stored in servers on the internet and cached temporarily on clients that include desktops, entertainment centers, table computers, notebooks, wall computers, hand-helds, sensors, monitors, etc.” - 2008 IEEE Internet Computing

History

Concept has existed since the 60s

The term ‘Cloud’ originates from telecommunications world of 1990s

John McCarthy – proposed the idea of computation being delivered as a public utility

Ramnath K. Chellappa – first academic definitiona computing paradigm where the boundaries of

computing will be determined by economic rationale rather than technical limits

History

Phases: Supercomputer

Single machine with many processors plugged into it

Cluster computing Collection of many smaller machines, each with a few number of

processors and independent memory

Grid computing Expands techniques of clustering but computers that form the grid are

pooled from different administrative domains and applied to a common task

Architecture

Most of the infrastructure consists of reliable services delivered through data centers that are built on servers with different levels of virtualization technologies

Open standards and open software are critical to the growth and survival of Cloud computing.

Architectural Layers & Services

Software as a Service Platform as a Service Infrastructure as a Service

Architectural Layers & Services

Software as a Service (SaaS) Term was coined by John Koenig in 2005 Software application delivery model where

the vendor develops and operates the software application for use by its customers via the internet

Architectural Layers & Services

Platform as a Service (PaaS) Provision of an environment that supports

the life cycle of web-application development available over the internet Design Implementation Testing Deployment Hosting

Architectural Layers & Services

Infrastructure as a Service (IaaS) Delivery of basic storage and computing

capabilities as standardized services over the internet. Provides:

Software Memory Data center space Storage

Types of Clouds Why migrate to the Cloud? Effectiveness Limitations Issues & Concerns Conclusion

Types of Clouds

Public External (3rd party provider)

Private Internal

Hybrid Both

Role PlayersCloud Providers

Provide infrastructure to SaaS providers and Cloud usersAmazonSalesforce.com

SaaS Providers/Cloud UsersCompanies and web application developers that make

use of resources made available to them by Cloud Providers

SaaS UsersNaïve end-users. Have little or no knowledge about

what goes on behind the Clouds.

Why migrate to the Cloud?

Pay-per-use model Only pay for what you use

Low cost of renting Amazon Scalable Service (S3) charges $0.12

to $0.15 per gigabyte per month

Reduce runtime and response time Split operations among multiple computing

nodes

Why migrate to the Cloud?

Security Advanced encryption algorithms

Transparency Just use the services, cloud maintenance is

for the providers to worry about

Effectiveness of Cloud Computing

New York Times’ TimesMachineConvert articles from 1851 – 1922 to PDF formatCould have taken 7 weeks but with cloud

computing technology, project was completed in 24 hours.

Animoto Scaled easily from 50 to 3500 servers in just 3 days

MapReduceDivide and conquer method is distributed across

multiple computers.

Issues & Concerns

Reliability Will the system be available all the time? January 2009: 40-minute outage at

Salesforce.com Affected over 900,000 subscribers

Portability Are services (business applications etc) and

data available from anywhere?

Issues & Concerns

Privacy & Security Who has access to what resources What happens to your private data if

You fail to pay your bills and your account is terminated?

Government prompts your cloud provider for it?

Conclusion

Cloud computing is here to stay

There still exists the possibility of a single point of failure, but probability of a failure is low because of how well the infrastructure is implemented.

It’s ability to expand and contract on demand makes it very ideal for businesses
