The document discusses a presentation given on cloud computing and how it can enable a more agile infrastructure. It begins with an introduction to cloud computing and Amazon Web Services, including computing, storage, and database services. It then outlines benefits of the cloud like elasticity, pay-as-you-go models, and avoiding delays from procuring your own infrastructure. In the end, it encourages attendees to experiment with building infrastructure in the cloud.

Really? Why?
Serenity vs Control

What is it?
Relevance with
Agile?

6. Services on our Infrastructure - e.g.
• Version Control System
• Build Server
• Tracking System
• Communication (e.g. wiki, workflow
engine)
• Test Labs
• Pre-Production Environment
• ... they all need to run somewhere!

11. Amazon Web Services (AWS)
• When I say “cloud” I mean Amazon’s
type of service
• On-demand resources for compute and
storage
• Ease of use: REST and HTTP(S)
• Hardware virtualization
• Gives users full control of environment
• Gives resource providers complete
isolation

12. Amazon Web Services (AWS)
• Why Amazon?
o Mature, stable, simple API
o Pay as you go model
o http://aws.amazon.com/
• Principal Services
o Elastic Compute Cloud (EC2)
o Simple Storage Service (S3)
o Elastic Block Store (EBS)
12/10/09 11

13. Amazon Web Services (AWS)
• S3 (Simple Storage Service) is a service
for storing and accessing data on the
Amazon cloud
o From a user’s point-of-view, S3 is
independent from the other Amazon services
o Data is built in a hierarchical fashion,
grouped in buckets (i.e. containers) and
objects
o Data is accessible via SOAP, REST and
BitTorrent
12/10/09 12

14. Amazon Web Services (AWS)
• Elastic Block Store
o Locally mounted storage
o Highly available
o Possible to breakpoint to S3

15. Amazon Web Services (AWS)
• Where is it?
o USA
o Europe (Ireland)
o More to come?
• Do we need to know?

Deployments are isolated
Resources only used when needed

20. Benefits of the Cloud
• Virtualization provides separation
between infrastructure and user runtime
environment
• Pay-as-you-go allows users to use the
service when they want and only pay for
what they use
• Elasticity of the cloud allows users to
start simple and expand their usage over
time

21. Agile Infrastructure
• Start your project fully resourced!!
• No more procurement delays
• Grow and shrink your infrastructure as
you
need it
• Avoid projects sharing resources and
cross-polluting each other
• More freedom from corporate IT policies
• Cloud providers can buy hardware faster
