DESCRIPTION
The goal of Continuous Delivery is to move your production release frequency from months to weeks or even days. This all sounds great, but is Continuous Delivery achievable in a complex enterprise IT environment running Java EE middleware such as WebLogic, WebSphere or JBoss? In this deck, Andrew Phillips, VP Products, XebiaLabs and Sriram Narayan, Product Principal, ThoughtWorks Studios examine the challenges of Continuous Delivery in a complex environment, the key drivers and benefits for moving to Continuous Delivery and simple ways to get started. We also demonstrate a Java EE delivery pipeline using ThoughtWorks Go and XebiaLabs Deployit that helps you get started and addresses the challenges commonly encountered in enterprise environments.

About XebiaLabs
About ThoughtWorks Studios
Continuous delivery is
an approach to delivering software that
reduces the cost, time, and risk
of delivering incremental changes to users.
What is Continuous Delivery?
o Your software is releasable throughout its lifecycle
o Your team prioritizes keeping the software releasable over working on new features
o Anybody can get fast, automated feedback on the production readiness of your systems any time somebody makes a change to them
o You can perform push-button releases of any version of the software on demand.
Continuous Delivery means…
Continuous Delivery isn’t just Automation
o Org design
o Devops – CAMS
o Culture, automation, measurement, sharing
o Pipeline Modelling (value stream)
o Visualization
o Orchestration
o Traceability and auditability
o Access control
o Complex projects and applications consisting of many components delivered by multiple teams
o Complex dependency trees, fan-in
o Polyglot applications, persistence
o Diverse, heterogeneous deployment landscape
o Environments : Physical, virtual, cloud
o Multi-site deployment e.g. CDNs
o Caches, laod balancers, search indexes, analytics data store
o Scheduled deployments
o Integration with Release Management
o E.g. how to gate a pipeline via change tickets?
o Need for end-to-end audit trail
Continuous Delivery in the Enterprise
o Deliverable: 2 EAR files with 2 WAR files each
o One of the WAR files built by a different team
o Also database changes, configuration files and server configuration settings
o Datasources, queues etc.
o Target environments
o Functional Test: Single server with in-memory DB
o Integration Test: 2-server clustered with external DB
o Performance Test: load-balanced 4-server cluster with external DB
o Release Management requirement: deployment to Performance Test environment requires change ticket
o Trigger: any code commit or update of the “external” WAR project
A Java EE Example
STEPS
1. Compile all changed WAR projects, take latest artifact for others
2. Compile EAR projects 3. Run unit tests
4. Run code quality build 5. Create deployment package (including SQL changes,
configuration files etc.)
6. Deploy to Functional Test env 7. Run functional tests 8. Deploy to Integration Test env
9. Run integration tests 10. Verify change ticket available for performance tests 11. Deploy to Performance Test env
12. Run performance tests, 13. Update change ticket
14. Notify business owner that build is “ready for prod”
A Java EE Example

A Vanilla Pipeline
o “Straight” translation of the release plan
o All steps happen serially
o Even though not all steps depend on the previous one
o Manual activities remain
o Will become a bottleneck over time
o Scripting, scripting, scripting
o E.g. packaging of the deliverable, deployment scripts to the different environments, some testing
o No clear visualization of component relationships and dependencies
o No clear insight into which code and features make up which components
A Vanilla Pipeline
