Pervasive Computing

Ubiquitous Computing

Existing everywhere

Embed microprocessors in everyday objects sothey can communicate information

Pervasive computing devices are completely

connected and constantly available.Convergence of wireless technologies,

advanced electronics and the Internet


4/36

Pervasive Computing

A computing technology that pervades the

users environment by making use of

seamless connectivity ofmultiple

independent information devices embedded

in the environment of the users.


5/36

Pervasive Computing

Applications:

- Smart Jackets

- Voice recognition- Disaster Alert

- Navigation / Transportation


6/36

Grid Computing

Grid computing is a method of utilizing thepower of many computers in a network to

solve problems requiring large number of

processing cycles and involving huge amountsof data.

> exploiting underutilized resources

> achieving parallel CPU capacity> providing virtual resources for collaboration and

reliability

> sharing resources


7/36

Grid Computing

Different computers connected together for

the purpose ofsharing resources.

Heterogeneous (different Platforms)

Parallel processing; faster communication

Exploring maximum potential Eg : GARUDA connecting IIT, C-DAC etc

Highlights of cloud computing

Services provided over the webCloud depictsinternet

No capital expenditure for the user- advantagefor smaller organisations

Pay per use billing model

Ease of scaling up or down

Order on line

No maintenance cost

Cloud computing - Examples

Hotmail 1996 first of its kindThe data is stored at the vendor servers, and users could pay incrementally toincrease disk space usage.

Some cloud computing applications that you arealready using

Face book, You tube , Twitter, Google docs etc

Cloud computing - How does it

work?

Front endclient/users computers, applicationneeded to access the cloud (web browser)

Back endcloud servers, storage,application

etc

Connected over a network/internet

Central server administers the operation,

monitors network traffic etc

Back up systems

Cloud computing

based on

Location

Public cloud

Private cloud

Hybrid cloudCommunity cloud


17/36

Public Cloud

computing infrastructure is hosted by the cloudvendor at the vendors premises.

customer has no visibility and control over where

the computing infrastructure

computing infrastructure is shared between manyorganizations.


18/36

Private Cloud

computing infrastructure is dedicated to aparticular organization and not shared with otherorganizations .

more expensive and more secure whencompared to public clouds.

Can be Externally hosted private clouds or On-

premise private clouds.


19/36

Hybrid Cloud

usage of both private and public clouds together

Organizations may host critical applications onprivate clouds and applications with relatively less

security concerns on the public cloud.

computing infrastructure is shared between anyorganizations.


20/36

Community Cloud

sharing of computing infrastructure in betweenorganizations of the same community.

Example - all Government organizations within a

state of may share computing infrastructure on thecloud to manage data related to citizens residingin that state

Cloud computing

based on

services provided

Infrastructure as a service ( IaaS)

Platform as a service ( PaaS)

Software as a service ( SaaS)


22/36

Infrastructure as a service - IaaS

Offers

Hardware CPU, Memory

Operating systems

Storage

Networking

Security etc

Can choose the power and number of your CPUs,size of storage , type of OS


23/36

Infrastructure as a service - IaaS

Offers hardware related services

Storage services

Virtual services

Popular Vendors /OfferingsIBM Blue house

Amazon EC2 Elastic Compute Cloud

Joyent

Go Grid etc


24/36

Platform as a Service -PaaS

Offers development/testing platforms

Important players in PaaS are

Google Application Engine

Microsoft Azure

Salesforce.coms force.com

Amazon Web Services

The client uses the platform and develops his applicationVery useful for small and start up software companies

Platforms provided by different vendors are typically not compatible.


25/36

Software as a Service -SaaS

Offers complete software offering

Users can access a software application hosted by the cloud vendor on pay-per-use basis.

The pioneer in this field has been Salesforce.com offering in the onlineCustomer Relationship Management (CRM) space.

SugarCRM,

IBM Lotus Live, Cisco Webex

ERP from many vendors including Ramco

HR functions, Payroll etc


26/36

SaaS - Benefits

no need to purchase software

easy upgrades

no need for IT personnel no need for purchasing servers

ease of getting up and running,

ease of adding or removing


27/36

SaaS - Challenges

both software and your data reside on theprovider's site,

outages (e.g. when the provider upgrades

equipment or programs), hackers

making sure that applications are written

according to accepted standards Proper contracts/SLA with SaaS providers.

Web Services Overview

A Web Service exposes functionality to a consumer

Over the Internet or intranet

A programmable URL

Functions you can call over the Internet

Based on Web standards

HTTP, XML, SOAP, WSDL, UDDI with more to come

Can be implemented in any language on any platform

Black boxes

Component-like, reusable
