Devops and Deployment Q: What does a talk like “Deployment is the new build”have to do with Devops* anyway? *yes, I know…

Devops and DeploymentA: We’re here because of shared experience that delivering valuerequires a holistic view of software development and maintenance

The Road to Value

The Road to ValueWe have ideas…

The Road to Value…think about how to implement them…

The Road to Value…write source code…

The Road to Value…test the source code…

The Road to Value…convert source code into deliverables…

The Road to Value…make those deliverables accessible to users…

The Road to Value…test the deliverables some more…

The Road to Value…make them available to end users…

The red bit• We have ideas…• …think about how to implement them…• …write source code…• …test the source code…• …convert source code into deliverables…• …make those deliverables accessible to users…• …test the deliverables some more…• …make them available to end users…• GOTO TOP

Why the red bit?Because our industry as a whole does this part really badly

Why the red bit?Because, if we take a holistic approach to softwaredelivery, we often identify this as a key area to improve

di-plȯi-mәnt• Deployment: taking the components that make up a release (typically a specific version of an application) and getting them correctly set up in an infrastructure environment so that the release is accessible to (end) users

di-plȯi-mәnt• Deployment: taking the components that make up a release (typically a specific version of an application) and getting them correctly set up in an infrastructure environment so that the release is accessible to (end) users Let’s talk “on-demand” environments and virtual appliances later

Deployment today Here be demons

Deployment here today do now maybe this this this then then this that that again then then this this phew!

The Road to Value

Remember this? make

Remember this?

Remember this?Here be demons

Build today GO!

Build todayHow did this happen?

How did this happen?1. Reusable commands2. Models3. Conventions++

Reusable commands• Recognising recurring low-level building blocks• Replacing copy’n’paste snippets with reusable libraries• Chunking sequences of low-level commandsThinking Ant here

Models• Common chunks work with common types of data• Formalise data chunks into a domain model• Formalise chunks of work into phases• Use language-/domain-specific defaultsThinking Maven here

Conventions++• Modifying a rigid convention-based system is cumbersome• Domain-/language-specific defaults and flow works out-of-the-box• Hook in with full control where you need toThinking Gradle here

How did this happen?• Not driven by industry standards! Just observation of common patterns• Changing out-of-the-box processes to match user expectation < user expectation changing to match out-of-the-box processes• “Mandatory” standards are quite flexible in practice

Deployment todayIn here: “Reusable commands” or a bit beyond

Deployment todayIn here: “Reusable commands” or a bit beyond Out there: make (if you’re lucky)

Deployment tomorrow? GO!

Getting to GO!• Develop a common model• (Re)discover vanilla• Support a “clean build”

Common model• Packages• Environments• Deployments

Common model• Version everything• Interoperability• “Something to work with”

Re(discover) vanilla• It Just Works™• KISS, YAGNI & more alphabet soup• Grandmother’s secrets

Re(discover) vanilla• Value reusability• Improve maintainability• Minimize “ripple” changes

“clean build”• Incremental as the goal• Clean as the fallback

“clean build”• Time To Rebuild < Time To Fix• Prerequisite: versioning• Prerequisite: known state for durable resources

Deployment is like the new build Deployment is the new build

Virtual appliances• Deliverable: ready-to-run system• “Press Play to start”• Model:  Package: virtual app  Environment: hypervisor/platform

Making virtual appliances• Deployment “ahead of time”  TBD: dealing with customization• Deployment at build time

Making working virtual appliances• Trust?• Eyeball?• Run and monitor?• ...?

Spoiled by CI• Great expectations  Unit testing  Integration testing  Pattern, style, compliance etc. checkers  Docs, change logs, reports etc.  …

The new CI? Unit testing ► file verification, ping Integration testing ► QA tests, application monitoring, DTrace Pattern, style, compliance etc. checkers ► policy engines, configuration checkers Docs, change logs, reports etc. …

Test ≠ Test• Test the configuration, not the configurator• Test the variable, not the template• Test what, not how

The new CI?• Food for thought  Quality builds  Dependent jobs  Platform agents  Virtual app repositories …

Building source code…that’s so 2011

Thank you!
