Fed up with stop and go in your data center? Shift into overdrive and pull into the fast lane!

Learn how AutoScout24, the largest online car marketplace Europe-wide, are building their Autobahn in the Cloud.
The secret ingredient? Culture! Because “Cloud” is only one half of the digital transformation story: The other half is how your organization deals with cultural change as you transition from the old world of IT into building microservices on AWS with agile DevOps teams in a true „you build it you run it“ fashion.
Listen to stories from the trenches, powered by Amazon Kinesis, Amazon DynamoDB, AWS Lambda, Amazon ECS, Amazon API Gateway and much more, backed by AWS Partners, AWS Professional Services, and AWS Enterprise Support.
Key takeaways: How to become Cloud native, evolve your architecture step by step, drive cultural change across your teams, and manage your company’s transformation for the future.

  26. 26. Same direction
  27. 27. 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.
