The document provides an introduction to cloud computing. It defines cloud computing as enabling on-demand access to configurable computing resources that can be provisioned with minimal effort. It then discusses how the cloud allows users to treat computing resources like a utility and pay based on usage, avoiding the need to build their own infrastructure. Finally, it outlines the benefits of cloud computing such as reducing costs, increasing agility, focusing on core competencies, and the types of cloud services including IaaS, PaaS, and SaaS.

1. The Cloud
An introduction

2. “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.”
-- National Institute of Standards and Technology

3. Huh?
Huh?

4. Think of it this way...

5. The Cloud allows you to
treat computers...

6. ...like electricity

7. You pay for only what
you use

8. You don’t have to build
your own infrastructure

9. You use as much as you
need, whenever you need

10. What does that mean to
me?

11. Pre-Cloud

You
Datacenter

12. Pre-Cloud
I need 30 servers Regular
You

13. Pre-Cloud
Give me a couple weeks Regular
You

14. Pre-Cloud
I only need them for 1 day Regular
You
Datacenter

15. Pre-Cloud
That’ll be $10,000* Regular

* Based on 1 month contract

21. Who are these
“Cloud Providers”?

23. Three Cloud
service models...

24. Types of Cloud Services
IaaS
(Infrastructure-as-a-Service)

25. Types of Cloud Services
PaaS
(Platform-as-a-Service)
IaaS
(Infrastructure-as-a-Service)

26. Types of Cloud Services
SaaS
(Software-as-a-Service)
PaaS
(Platform-as-a-Service)
IaaS
(Infrastructure-as-a-Service)

27. Types of “Cloud” Services
SaaS
(Software-as-a-Service)
PaaS
(Platform-as-a-Service)
IaaS
(Infrastructure-as-a-Service)

28. IaaS
(Infrastructure-as-a-Service)
Examples: Amazon EC2, Rackspace Servers
You have “root” access on a virtual Linux or Windows
machine
You are responsible for installing system packages,
scaling, and failover
The big difference is that you don’t own, manage, or
commit to the hardware
Most discussion about the Cloud focus on the IaaS
layer, and is the easiest for companies to understand*
* Most of this presentation focuses on IaaS as well

29. PaaS
(Platform-as-a-Service)
Examples: Google App Engine, Force.com
Your application lives in a sandbox, with limited
access to the O.S. and file system
In exchange, the system automatically handles
configuration, scaling, and failover
Similar to the advantages that modern languages
(e.g. Ruby-on-Rails) provide
Cost based on usage

30. SaaS
(Sofware-as-a-Service)
Examples: Salesforce.com, Twitter
A fully-baked service that requires no coding
Flexibility and customization is limited to what
the service allows you to do
Advantage of SaaS services over locally installed
software is that you don’t have to maintain it,
and you can use it anywhere
Generally subscription based

31. What makes you a
“Cloud”
1. Elastic (on-demand capacity)
2.Self-service (provisioning through API/UI)
3.Pay-for-usage (no long term contract)
4.Virtualized (all servers look/act identically)

32. Other “Cloud” services
Storage (e.g. Amazon S3, Rackspace cloudfiles)
Load balancing (e.g. UltraDNS, Amazon Elastic Load Balancing)
CDN (e.g. Akamai, Limelight, Amazon CloudFront)
Backups (e.g. Carbonite, Mozy)
Productivity (e.g. 37signals Basecamp, Zoho)
Personal (e.g. YouTube, Facebook)

45. You lose

46. You lose visibility

Cloud

vanish

49. Where do things go
from here?

50. Where do things go
from here?
Early adopters will prove the ROI
Cloud providers will continue to innovate and
address concerns
Trust in the cloud will increase
Companies will stop asking “What can I move to
the Cloud?”, and instead ask “What CAN’T I
move to the Cloud?
Eventually PaaS will overtake IaaS
