The document discusses Cloudesire, a tech startup that developed a cloud application marketplace, and highlights the evolution from traditional waterfall development models to agile methodologies emphasizing infrastructure as code. It introduces tools like jclouds and Opscode Chef for automating cloud infrastructure management. The presentation concludes with an invitation to try the Threehops service compatible with various OpenStack cloud providers.

Once upon a time… waterfall model
● Sequential process
● Manual testing
● Scheduled releases
● Hard to deploy
● Physical
infrastructures

4. #1 OpenStack Day Milano 2014 - CC BY - ClouDesire
Nowadays… lean, agile, #buzzword
● Rapid-changing
requirements
● Faster iterations
● Automated testing
● Disposable cloud
resources

Focus on infrastructure risks
● A jungle of IaaS providers, multiple API
dialects.
● Different environments for each application:
development, staging, production.
● Environments grow fast as the app
requirements.
● Server configurations should be tested, too.

Let’s start to aim the target
We need to...
● manage infrastructure with code
● define infrastructure as code
● version infrastructure as code
● test infrastructure as code
● do it faster and more often. Continuously.
● Automate all the things!

Universal Cloud API
JClouds is a Java/Clojure open-source library
that provides an abstraction layer between
multiple cloud resources.

Automated Infrastructure
● Stop thinking about servers and start to
model services and resources
● Infrastructure as a code
● Build reusable components to manage
resources
● Integration Testing

Automated Infrastructure - Opscode Chef
● Opscode Chef http://www.getchef.com/
● Chef relies on reusable definitions known as
cookbooks and recipes that are written in
Ruby.
● Cookbooks and recipes automate common
infrastructure tasks.
● Chef applies those definitions to servers to
produce an automated infrastructure.
