The document discusses the commercial aspects of cloud computing. It describes how traditional systems involved high costs for hardware and underutilized capacity. Cloud computing provides software, platforms and infrastructure as on-demand services with scalability, reduced costs and increased reliability. Some examples given include Salesforce.com, ClickDesk and Amazon EC2. The document outlines advantages of cloud for situations with variable traffic loads and discusses barriers to cloud adoption like data security, legacy applications and internet connectivity requirements.

2. Agenda
• Traditional Systems
• Systems evolution over the last 2 decades
• Shift towards Web 2.0, internet
• Cloud = Software as a Service +
Infrastructure as a Service + Platform as a
Service
• Instances where cloud is needed
• Advantages
• Barriers to Cloud Computing
• Summary

3. Shift to cloud computing…

4. Traditional Software Solutions
• Main Frame
• Batch Processing
• Heavy servers
• Parallel processing units
• High Cost
• Disadvantages
– Underutilization of capacity
– Not very cost effective
– Not affordable by small and medium enterprises

5. Advance Solutions like ERP
• Client Server Architecture
• New approach of system integration
– XML, SOAP
• Usage of Dedicated servers based on
maximum load expected for the system
• Capital intensive system with high initial
investment for hardware and softwares
• Interconnected environment within
organization

7. The Traditional Server Concept
• Pros • Cons
– Easy to conceptualize – Expensive to acquire and
– Fairly easy to deploy maintain hardware
– Easy to backup – Not very scalable
– Virtually any – Difficult to replicate
application/service can be – Redundancy is difficult to
run from this type of setup implement
– Vulnerable to hardware
outages
– In many cases, processor is
under-utilized

9. Concept of Software as Service

10. Software as a Service (SAAS)
• Pricing based on Per Unit Usage of system
– Transaction
– Per User
– Data access
• Examples of SAAS
– Business Emails
– Live Chat Solutions ClickDesk
– Google Apps
– Android Apps, GotoMeeting

11. Salesforce.com – SaaS pioneer
• Customer Relationship Management (CRM)
– availability of 99.9% for cloud infrastructure
– Sales, Service & Support, Partner Relationship
Management, Marketing, Content, Ideas and
Analytics modules
– Customization on the platform- or the tab-level
• AppExchange
– Directory of third-party apps for Salesforce
– over 800 apps from 450 ISV
• Web Services API
– enables integration with other systems
– wrapper libraries for Java, and .NET

12. ClickDesk.com
• Pricing based on Usage
• Total No of Live Chat Agents
• Total Features Subscribed for
• Plug and Play kind of Solution for Websites

13. CCAvenue Payment Gateway
• Good Example of Software as A Service
• Pay per Transaction
• Takes care of all credit card,debit card,
internet banking
• Security and data regulation as per RBI
• Useful Plug and play model for eCommerce
Web Applications

14. Infrastructure as a Service (IAAS)
• Choice of Multiple OS, Platforms and
Databases and Content Delivery Network all in
one place
– Service Provides : Amazon EC2, GoGrid
• IAAS Subscribers
– Farmville, MafiaWars
– 230 million Users, uses 12000 servers on Amazon
• India IAAS Provides
– Netmagic Solutions, Insta Compute ( Tata Comm.)

15. Example of IAAS Pricing

16. Instances where Cloud is required
• Traffic for the website is variable
• Day Traffic is more
• Seasonal traffic is expected
– Examination Result Server
– Online Ticket booking during seasonal period
– eCommerce site during festival Season
– Admission Server during admission seasons

18. Web Site Traffic Analysis
• Number of Visitors at particular instance
• No of processes running on the system
• Complexity involved during the processes
• Complexity of the database operations
• Total processor and RAM memory required to
execute the process
• Load Balancer shifts the traffic to another
server

19. Cloud computing takes virtualization
to the next step
• You don’t have to own the hardware
• You “rent” it as needed from a cloud
• No need to purchase Software Licenses
• No need to worry about software, hardware
upgradation

22. Cloud Computing
...is a computing paradigm where the boundaries of
computing will be determined by economic
rationale rather than technical limits
The concept generally incorporates
combinations of:
• infrastructure as a service (IaaS)
• Virtualization
• platform as a service (PaaS)
• Google APP Engine
• Microsoft Azure
• Software as a service (SaaS)
• Business Applications

23. Advantages of Cloud Computing
• Software as Subscription
• Reduced Software Maintenance
• Increased Reliability
• Increased Scalability
• Cost Reduction
• Portability/ Accessibility

24. Suppose you are a Stock Exchange
• You offer on-line real • Why pay for capacity
time stock market data weekends, overnight?
9 AM - 5 PM,
M-F
Rate of
Server
Accesses
ALL OTHER
TIMES

25. Solution for Services like Stock Exchange
• Host the web site in Amazon's EC2 Elastic
Compute Cloud
• Provision new servers every day, and
deprovision them every night
• Pay just $0.10* per server per hour
– * more for higher capacity servers
• Let Amazon worry about the hardware!

26. Education Institute on Cloud
• Processes
– Pre Admission, Admission Processes
– Student Test Preparations
– Online Examinations
– Examination Results Management
• Demand/ Peak Period
– Admission Season
– Examination Day
– Result Day

27. Education Institute on Cloud…
• Capacity Calculations based on
– Total No of Students applying to institute
– Concurrent connections to the server
– Total memory required for each web request
connection
– Concurrent online examination terminals active at
a time

28. Barriers to Cloud Computing
#1 Data Security
• Many customers don’t wish to trust their data to
“the cloud”
• Data must be locally retained for regulatory
reasons : e.g Govt. confidential data
#2 Application Availability
• Cannot switch from existing legacy applications
• Equivalent cloud applications do not exist
#3 Continuous Internet connection is required

29. Summary
• 35% of world’s IT systems will be on cloud by
2013-14
• New projects are being implemented in cloud
• New Services , Softwares would be internet
based
• Personal computers might not need high
capacity to run applications
• Cloud services are simpler to acquire and scale
up or down
