7 AT A GLANCE VIPER Platform 7

8 VIPER Platform Reactive and non-blocking Entity Data Model and Graph Database Separate systems/services for structured and binary data Distributed in multiple Docker containers for maximum flexibility Supported by the Austrian Research Promotion Agency

9 WHERE WE CAME FROM PREVIOUS ARCHITECTURE 9

10 Classic Spring Architecture Java 6/7 (some 8, but not much) Service oriented architecture Spring Framework Hibernate + SQL Solr Search Server Own API Java SDK SOAP REST Strong Focus on non-functional aspects Security, Latency, Throughput 10

11 Pain Points Service Architecture + Hibernate + SQL Database High latency architecture Architecture requires consecutive DB accesses ~120 Threads without load 200+ Threads in high load situation Java Executor Service for performance Thread per HTTP connection 11

12 A NEW PRODUCT AN OPPORTUNITY Existing Technology Complete Separate Development New Platform 12

13 Vision One Product Line One Technology

14 What the Big Players do 14

15 What the Big Players do Non-blocking & Reactive Microservices No SQL Graph Queries Containers 15

16 WHAT WE WANT TO ACHIEVE ARCHITECTURE REQUIREMENTS 16

17 Goals of the Platform Highly Structured Data Deployment Flexibility Distributed Clients and Data Scalability Realtime Updates Extendable An Awesome Framework

18 Data Driven Highly structured and connected data Strong visualization of logical data view Calvinius 18

19 Design Principles Query and deliver as much data as needed in one step Optimized data flow First data arrives at destination while source is still providing Common data abstraction on frontend and backend Static Typing 19

23 Entity Data Model 23

24 Entity Data Model and Graph Database 24

25 Query and Modification Language - QAML Fluent API to query and modify graph like data Available in Java and TypeScript Type safe It s reactive EMF based generators Supports multi-inheritance 25
