Why Microservices?
Speed
Independent deployable
Fast local decisionsAutonomous teams
Strong boundaries
Loosely coupled Technology diversity

PRINCIPLES
High-Level Principles
DESIGN AND DELIVERY
PRINCIPLES
Tactical measures
REDUCE TIME TO MARKET
Establish fast feedback loops to learn, validate and
improve. Remove friction, hand-offs and undifferentiated
work.
MOBILE FIRST
Start small and use device capabilities.
SUPPORT DATA-DRIVEN DECISIONS
Provide relevant metrics and data for user and market
insights. Validate hypothesis for problems worth solving.
YOU BUILT IT, YOU RUN IT
The team is responsible for shaping, building, running and
maintaining its products. Fast feedback from live and
customers helps us to continuously improve.
ORGANIZED AROUND BUSINESS CAPABILITIES
Build teams around products not projects. Follow the
domain and respect bounded contexts. Make boundaries
explicit. Inverse Conway Maneuver.
LOOSELY COUPLED
By default avoid sharing and tight coupling.
No integration database. Don’t create the next monolith.
MACRO AND MICRO ARCHITECTURE
Clear separation. Autonomous micro services within the
rules and constraints of the macro architecture.
AWS FIRST
Favor AWS platform service over managed service,
over self-hosted OSS, over self built solutions.
DATA-DRIVEN / METRIC-DRIVEN
Collect business and operational metrics. Analyze, alert
and act on them.
ELIMINATE ACCIDENTAL COMPLEXITY
Strive to keep it simple. Don’t over-engineer.
Focus on necessary domain complexity.
AUTONOMOUS TEAMS
Make fast local decisions. Be responsible. Know your
boundaries. Share findings.
INFRASTRUCTURE AS CODE
Automate everything: Reproducible, traceable, auditable
and tested. Immutable servers.
CROSS-FUNCTIONAL TEAMS
Engineers from all backgrounds work together in
collaborative teams as engineers and share
responsibilities. No silos.
BE BOLD
Go into production early. Value monitoring over tests.
Fail fast, recover and learn. Optimize for MTTR not MTBF.
SECURITY, COMPLIANCE AND DATA PRIVACY
Build with least privilege and data privacy in mind.
Know your threat model. Limit blast radius.
COST EFFICIENCY
Run your segment in the right balance of cost and value.
ONE SCOUT IT
Foster collaboration. Harmonize and standardize tools.
Pull common capabilities into decoupled platform services.

BEST TALENT
Autonomy, Purpose and Mastery: We know why we do
things, we decide how to approach them and deliberately
practice our skills.
Build
MeasureLearn
Autonomous teams
business capabilities
organized around
collaboration culture
You build it,
you run it.
Monitoring is the new testing
How (not) to share
shared nothing as default
loosely coupled
fast local decisions
voluntary adoption
exception: macro concerns
Follow the
trail
Continuous

one repository per
service.

Reactive Microservices Roadshow Berlin

  • 1. Reactive Microservices Roadshow | 28.09.2016 | Christian Deger Highway to heaven Building microservices in the cloud
  • 4. Microservices in the cloud adoption?
  • 5. 2000 Servers 2 Data Centers MTBF optimized
  • 6. Dev and Ops Silos Development “Change” Operations “Stability”
  • 11. 21st Century What does a tech company look like?
  • 13. Great Design Universally Connected Mobile First Instant Business Value Massive Data Insight Highly Available
  • 14. good, but not great Hmm, we are
  • 17. .NET / Windows to JVM / Linux Monolith to Microservices Data center to AWS Devs + Ops to Collaboration culture Involve product people
  • 19. No traction in major internet companies Major JVM Languages
  • 20. Major JVM Languages No traction in major internet companies Not accepted by C# developers
  • 21. Major JVM Languages No traction in major internet companies Not accepted by C# developers Attracts talent Is a starting point
  • 22. Why Microservices? Speed Independent deployable Fast local decisionsAutonomous teams Strong boundaries Loosely coupled Technology diversity Scale the organization
  • 24. STRATEGIC GOALS Goals of the business side ARCHITECTURAL PRINCIPLES High-Level Principles DESIGN AND DELIVERY PRINCIPLES Tactical measures REDUCE TIME TO MARKET Establish fast feedback loops to learn, validate and improve. Remove friction, hand-offs and undifferentiated work. MOBILE FIRST Start small and use device capabilities. SUPPORT DATA-DRIVEN DECISIONS Provide relevant metrics and data for user and market insights. Validate hypothesis for problems worth solving. YOU BUILT IT, YOU RUN IT The team is responsible for shaping, building, running and maintaining its products. Fast feedback from live and customers helps us to continuously improve. ORGANIZED AROUND BUSINESS CAPABILITIES Build teams around products not projects. Follow the domain and respect bounded contexts. Make boundaries explicit. Inverse Conway Maneuver. LOOSELY COUPLED By default avoid sharing and tight coupling. No integration database. Don’t create the next monolith. MACRO AND MICRO ARCHITECTURE Clear separation. Autonomous micro services within the rules and constraints of the macro architecture. AWS FIRST Favor AWS platform service over managed service, over self-hosted OSS, over self built solutions. DATA-DRIVEN / METRIC-DRIVEN Collect business and operational metrics. Analyze, alert and act on them. ELIMINATE ACCIDENTAL COMPLEXITY Strive to keep it simple. Don’t over-engineer. Focus on necessary domain complexity. AUTONOMOUS TEAMS Make fast local decisions. Be responsible. Know your boundaries. Share findings. INFRASTRUCTURE AS CODE Automate everything: Reproducible, traceable, auditable and tested. Immutable servers. CROSS-FUNCTIONAL TEAMS Engineers from all backgrounds work together in collaborative teams as engineers and share responsibilities. No silos. BE BOLD Go into production early. Value monitoring over tests. Fail fast, recover and learn. Optimize for MTTR not MTBF. SECURITY, COMPLIANCE AND DATA PRIVACY Build with least privilege and data privacy in mind. Know your threat model. Limit blast radius. COST EFFICIENCY Run your segment in the right balance of cost and value. ONE SCOUT IT Foster collaboration. Harmonize and standardize tools. Pull common capabilities into decoupled platform services.

  • 28. You build it, you run it.
  • 29. Monitoring is the new testing
  • 30. How (not) to share shared nothing as default loosely coupled fast local decisions voluntary adoption exception: macro concerns
  • 33. Application code in one repository per service. CI Deployment package as artifact. CD Deliver package to servers Delivery Pipeline – Data Center
  • 34. Application code and infrastructure specification in one repository per service. CI Deployment package and infrastructure declaration as artifact. CD 1. Create or update service infrastructure. 2. New instances pull down package and start application. Delivery Pipeline – AWS
  • 39. SQS + S3 Kinesis + S3 Kinesis + DynamoDB SQS + DynamoDB Proxy + DynamoDB DynamoDB Evolution
  • 43. PageSpeed Module css (page+fragment) js (page+fragment) ngx_pagespeed css (page) js (page) css (fragment) js (fragment)
  • 45. Event Sourcing one way data highway and data pumps
  • 46. Commit to Production 20 Minutes Cycle Time New Service 1 Day Service Bootstrapping 3 Days Frontend 4 Days Backend
  • 47. 015 Teams 025 Lambda Functions 200 Repositories 040 Microservices 009 Systems Status Quo
