1 Today’s Unicorn • Recap from Velocity & PERFORM 2015• Why we don’t have to be like Facebook

2 Why Unicorns Excel? • Speed through automation• Quality through metrics

3 Metrics and approach • Service, business & user metrics• Pre-Prod - from integration and load

tests• Prod - from real-users

4 Dynatrace andXL Release by XebiaLabs

• Building a metric-driven pipeline

Today’s agenda

U N I C O R N S T A T U S

700 deployments / year

10 + deployments / day

50 – 60 deployments / day

Every 11.6 seconds

• Waterfall agile: 3 years• 220 Apps - 1 deployment per month• “EVERY manual tester does automation”• “We don’t log bugs. We fix them.”

• Measures are built in & visible to everyone• Promote your wins! Educate your peers.

• EVERYONE can do continuous delivery.

CHALLENGE

“Deploy Faster!!”

Fail Faster!

It‘s not about blind automation of pushing more bad code through a shiny pipeline

879! SQL Queries8! Missing CSS & JS Files

340! Calls to GetItemById

Example #1: Public Website based on SharePoint

Example #2: Migrated to (Micro)-Services

26.7s Execution Time 33! Calls to the

same Web Service

171! SQL Queries through LINQ by this Web Service –

request similar data for each call

Architecture Violation: Direct access to DB from frontend logic

Key App Metrics # SQL (INS, UPD, DEL, …)

One goal: deliver better features to customers fasterTwo fundamental components: speed + quality

When, and how, should we measure?

Not just in production!

Measure as early as possible in your development and delivery process

Fast feedback is both more effective and cheaper at identifying and fixing problems

Reuse what you already have - automated “functional” tests but convert them into Architectural, Performance and Scalability Validation Tests

When, and how, shall we measure?

Metric-DrivenContinuous DeliveryWith Dynatrace & XL Release by XebiaLabs

• XebiaLabs XL Release is a pipeline orchestrator• It allows you to define, execute, track and improve all the tasks in your

delivery pipeline• All = Automated + manual, technical + process-oriented• Insight, visibility and control into people and tools

Orchestrating your delivery pipeline with XL Release

XL Release and Dynatrace XL Release by XebiaLabs allows you to integrate

Dynatrace quality metrics into your overall Continuous Delivery pipeline

Automatically verify architectural quality during your integration testing

Trigger and review performance monitoring results Automatically register releases in Dynatrace to allow for

“before/after” comparisons of user behavior Deliver better software and close the Continuous

Delivery feedback loop!

Quality metrics in your unit & integration tests

ArchitecturalQuality Metrics from

Unit & Integration Tests

#1: Analyzing every Unit & Integration test

#2: Metrics for each test

#3: Detecting regression based on measure

Unit / Integration Tests are auto baselined! Regressions auto-detected!
