Infrastructure... What is it?

Relevance with Agile?

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!

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

Amazon Web Services (AWS)

• Why Amazon?o Mature, stable, simple APIo Pay as you go modelo http://aws.amazon.com/

• Principal Serviceso Elastic Compute Cloud (EC2)o Simple Storage Service (S3)o Elastic Block Store (EBS)

Amazon Web Services (AWS)

• S3 (Simple Storage Service) is a service for storing and accessing data on the Amazon cloudo From a user’s point-of-view, S3 is

independent from the other Amazon serviceso Data is built in a hierarchical fashion,

grouped in buckets (i.e. containers) and objects

o Data is accessible via SOAP, REST and BitTorrent

Amazon Web Services (AWS)

• Elastic Block Storeo Locally mounted storageo Highly availableo Possible to breakpoint to S3

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

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
