3 Built and Test in the Cloud A Build Masters Guide Darryl Bowler Professional Services What you will learn in the next 90 minutes Why build software using cloud technologies Business and technical reasons Overview of a cloud provider Amazon EC2 VPC Virtual Private Cloud Qualities of a cloud (for software development) Build tools Hudson What is Hudson? Continuous Integration (and deployment) Provision build-slaves into the cloud Amazon EC2 plug-in Artifact repositories (Apache Archiva and Sonatype Nexus) The need for a artifact repository Selenium and automated web tests Selenium Grid

4 Cloud Providers and Management Many to choose from Reasons to Build on in the Cloud Follow principles of lean manufacturing a production practice that considers the expenditure of resources for any goal other than the creation of value for the end customer to be wasteful, and thus a target for elimination THIS IS OUR GOAL! Predictable resource pool of compute Dynamic provisioning of system resources Pay as you need model REAL-TIME!! Instant feedback

5 Qualities of a Cloud (for software development) On-demand provisioning Cross platform Can provision a multitude of operating systems and stacks Rich API Ease of integration into workflow System provisioning become a service Multi-tenant Flexible RBAC to separate duties and operations Measurable with a charge back reporting Library of pre-built (reusable) images Empowers developers Increased productivity Integrate cloud capabilities into their development tools (IDE) opyright Amazon Web Services Comprehensive Management Interface Accounting, provisioning and configuration Amazon Elastic Compute Cloud (Amazon EC2) Heterogeneous system, pay for what you use model Amazon Virtual Private Cloud (Amazon VPC) Integration with corporate network Amazon Simple Storage Service (Amazon S3) Amazon SimpleDB & Relational Database Service (Amazon RDS)

6 Amazon EC2 Provision a pre-built system image in minutes AMI = Amazon Machine Image Create your own AMI Library of images available to developers Security and IP filtering available Multitude of Linux distros, Windows Server 2003/2008, OpenSolaris Provision in various geographical locations Western Europe, USA East and West and SE Asia Pacific AWS Console

7 Amazon EC2 Tools Amazon EC2 AMI Tools Command line tool Can be used in a build workflow ec2-describe-images -o self IMAGE ami-f41afe9d /hudsonbuild/image.manifest.xml available private i386 machine instance-store IMAGE ami-c59676ac hudson_slave_with_swarm/image.manifest.xml available private i386 machine instance-store ec2-run-instances ami k DBKEY RESERVATION r-3a454c default INSTANCE i-31f8c55b ami pending DBKEY 0 m1.small T01:09: us-east-1c monitoringdisabled instance-store Virtual Private Cloud (VPC)

8 Hudson Extensible continuous integration server Java build tool java -jar hudson.war or servlet container such as Tomcat Can run on many platforms Fully configurable from GUI, unlike CruiseControl Monitoring executions of externally-run jobs Other extensive features Change set support, RSS/ /IM Integration, Distributed builds, File fingerprinting and Plug-in Support Hudson support tools/processes that your team uses!! DISTRIBUTED and SCALABE! Master / Slave FEATURES OF CI A connection to a version control repository A build script Feedback mechanism SMS A process for integrating the source code Automated inspection and testing 2 Copyright 2008 CollabNet, Inc.

9 THE VALUE OF CI Reduced Risk Defects detected and fixed sooner Reduce repetitive manual processes Automated integration, build, inspection and test Allows for more productive and creative work Generate deployable software at any time Health of software is measurable Enable better project visibility More effective decisions (Quality metrics) Establish greater confidence in the software product 3 Copyright 2008 CollabNet, Inc.

10 The Case for Continuous Deployment Another lean software development method Continuously and automatically deploy software in production or development Rapid method of placing features/changes into production Requires rigorous testing Production clustered environment Real-time monitoring and altering Rollback Great to show work developed during and end of sprints Hudson can deploy to Websphere, JBoss and Tomcat Deployment using Hudson

11 The Case for Continuous Deployment Using EC2 as a Dynamic Scalable Build Farm A build farm that scales depending on the build load Requires pre-built AMI s Library of pre-built AMI s representing all build stacks Reasons Near real-time builds Pay for what you use No waiting on resources Automation and reuse implied Applies to the Lean model

12 Hudson Amazon EC2 Plug-in Building Software in a VPC

13 Web Testing with Selenium A platform to automate web tests Cross operating system and web browser support An API that can be driven from various languages C#, Perl, Java, PHP Python and Ruby Can be used within a (automated) testing framework Bromine, JUnit, NUnit, RSpec (Ruby) 3 step process Write and run testing a Firefox plug-in (IDE) Use Selenium remote control to customize to execute in different browsers and platforms Use Selenium grid to execute distribute parallel testing across platforms and operating systems The case for an Artifact Repository Apache Archiva and Sonatype Nexus an extensible repository management software that helps taking care of your own personal or enterprise-wide build artifact repository. It is the perfect companion for build tools such as Maven, Continuum, and ANT Quote from Act as highly configurable proxies between your organization and the public Maven repositories Save hundreds of requests over HTTP, and, in very large multiproject builds, this can shave minutes from a build. Provide an organization with a deployment destination for your internally generated artifacts Central (Enterprise wide) software artifact repository FOSTERS REUSE, TRACEABLY and CONSISTENCY!!! Apache Ivy dependency management
