5. Today, a small team can
easily build an
application that’s used
by millions of people
world-wide
5

6. 30+ million users, 2 backend engineers, acquired for $1B

8. Cloud Computing
Cloud computing is a model of delivering
computing resources from the Internet to the
end-user
8

9. Technical Definition
Cloud computing is a model for enabling
convenient, on-demand network access to a
shared pool of configurable computing
resources (e.g., networks, servers, storage,
applications, and services)
that can be rapidly provisioned and released
with minimal management effort or service
provider interaction.

10. Service Models- An Analogy
Suppose you have moved to new
town and want to find an

11. Build a New house ( IaaS)
Difficult, time consuming
11

12. Infrastructure as a Service (IaaS)
 Delivers basic network, storage, and compute-
processing capabilities as standardized, scalable
service offerings
 Target:
o Developers and ISV
Examples
o Amazon EC2
o RackSpace Cloud Servers
o Smugmug- a paid digital photo sharing service

15. Platform as a Service (PaaS)
 Application middleware offered as a service to
developers, integrators, and architect
 Hides machines, storage etc
 Target: Developers and SME

20. Why
Platform-as-a-Service?
20

21. Let’s imagine that you
want to deploy an app…
 Do you know how much hardware to buy?
 Can you afford it?
 How long does it take to approve, buy and
install?
 Who is going to set it up?
 Can you handle a 10x increase in traffic?
 Can you afford a test lab?
21

22. PaaS
=
Build Application
+
Maintain Application + Scaling
Development tool itself is hosted in the cloud and accessed through a browser
Deploy applications without any specialized systems administration skills
22

23. How PaaS benefits IT?
Rapidly Deliver Integrate with
New Capabilities Provide access to
other Web and
Cloud Applications all devices,
customers and
Cost-effectively scale Increase partners
environment to meet Operational
business demand Efficiency
Re-use Existing
Investments
Reduce Data Avoid Operating Reduce Time
Center Footprint Expenses, Preserve to Market
Capital
23

24. What Makes PaaS Different?
Integrated
Multi-tenant management:
development: monitoring ability is
multiple users, each provided by the
with multiple active development
projects platform
Multi-tenant : load Integrated
balancing, failover are billing
provided by the
development platform
itself)

26

27. Google App Engine
Easy to build Easy to maintain Easy to scale as
your traffic and data storage needs grow
• No servers to maintain: upload your application,
and it's ready to serve your users
