Benefits: • Local control = more reliable • Less traffic = LowerTCO • Edge integration & event processing & analytics / machine learning

15. Build Cloud-Native, Lightweight Microservices • Public Cloud • Containers on PaaS • Serverless Architectures Use Cases for Flogo IoT Edge Applications • Consumer IoT • Industrial IoT Initial Use Case Other Options

17. © Copyright 2000-2017 TIBCO Software Inc. Why Go? Modern programming language Getting a lot of traction due to usage in frameworks like Docker or Kubernetes Concurrency Built into the language (Goroutines, channels, no explicit thread programming) Memory management Modern Garbage collector Statically typed Type-safe development with no “surprises” during runtime “Partly” object-oriented Simple and flexible type system, composition instead of inheritance Zero-dependency programming model All-included binary file, no dependent “external” libraries Speed Ultra fast compilation and startup time, very lightweight footprint

18. Comparison – Resource Requirements of IoT Integration Frameworks Eclipse Kura Node-RED Flogo VM JVM JavaScriptV8 Golang Base Disk Space 59 MB 56 MB ~ 0 MB Base Runtime Memory ~ 170 MB (with Open JDK) ~ 20 MB (with Oracle Embedded Java) > 50 MB ~ 5 MB Startup time Slow (~8 sec) Slow (~5 sec) Fast (~1 sec) Application Build Slow Not Applicable Fast (~2 secs)

19. Flogo Repositories on Github flogo-lib Core libraries. flogo-services Backing services required by Flogo for flow and state management. flogo-contrib Flogo extensions available out of the box, like triggers or activities. flogo-cli A command line tool to build Flogo apps. https://github.com/TIBCOSoftware/flogo (very permissive open source BSD license) Flogo Web Designer available for free as Docker Image

24. Amazon IoT Reference Architecture Potential use cases • Event-driven Flows • Device Lifecycle Mgmt • Orchestration Core Integration Agile Microservices API Management
