2. Agenda
• Why learn about Cloud Computing?
• What is Cloud Computing?
• Evolution to Cloud Computing
• Cloud Computing Architecture
• Fundamental Cloud Services
o SaaS , PaaS, IaaS
• Deployment models
• Pros and Cons
• What does it mean to developer?
• Conclusion

3. Why Learn about Cloud Computing?
• Seen an acceleration in
adoption of cloud computing
and cloud services
• It is mentioned as one of the
top 5 technology trends to
watch in next 4-5 years by a
report from Gartner
• Everybody is talking about it , It’s a buzzword..!
4. What is Cloud Computing?
• Services and Solutions that are
delivered and consumed in real
time over internet are Cloud
Services
– When you store your photos
online, use webmail or a social
networking site, you are using a
“cloud computing” service
• Cloud computing is a delivery
model of computing services
over the Internet
– It enables real time
development, deployment and
delivery of broad range of
products , services and solutions
5. Common Cloud Characteristics?
• On Demand Self Service
• Ubiquitous network Access: Anywhere, Any
time ,Any Device
• Location independent Resource Pooling
• Rapid Elasticity
• Pay as you go
6. Supporting Factors for Cloud Computing
• Combined affect of following factors have
made Cloud Computing a compelling Paradigm
– Advancement in processors
– Virtualization technology
– Distributed Storage
– Automated Management
– Broadband internet Access
– Fast and Inexpensive Servers
8. Enabling Technologies for Cloud Computing
• Essential building blocks of several Cloud based
Services
• Virtualization: is simulating a hardware
platform, operating system (OS), storage
device, or network resources
• Virtual Machines:
– VMWare and XenSource
• Virtual FileSystem:
– Google File System and VMFS
15. Software as a Service
• Most Known and first Service , major service given
as part of Cloud Computing service
• In this case the application itself is provided by the
service provider, typically via web browser
• Gartner estimates that SaaS revenue will be more
than double its 2010 numbers by 2015 and reach a
projected $21.3bn
• Examples
– User mail: Gmail, Hotmail etc,
– User Pics: Picasa , Flickr
– Enterprise: Webex, OfficeLive
16. Platform as a Service
• PaaS – Platform as a Service
• Hosted application environment for developing
and deploying cloud based applications
• Examples
– Google’s App Engine
– Amazon EC2
– Microsoft Azure
17. Infrastructure as a Service
• IaaS – Service provider offers capacity for rent
basically hosted Data centers and Servers
• An evolution of web site and server hosting
services which provided servers and Virtual
Private servers
• Examples
– AT&T – Hosting and Storage
– Rackspace
– Amazon EC2
25. What does it mean to software developer?
• Cloud Computing is an extension of distributed
models of Software development and delivery
– The software is composed of interoperable third party
components
– The execution happens in distributed manner on multiple
computers
– The ownership is distributed between multiple
organizations
– Generally source code is not available for third party
components
26. Challenges to software practices
• Challenges it imposes to Software Practices
– Third party Service/component selection
– System Inspection and Debugging
– Coping with the evolution of third party
services
– Separation of ownership
28. Conclusion
• Cloud Computing is evolved by consolidating
several Technologies like SaaS, Grid and
virtualization
• Major 3 services: Saas, PaaS and IaaS
• 3 deployment models: Private, Public and Hybrid
• From software development perspective it is an
extension of distributed computing
