RPA (Robotic 10 Millionen KI hat größeres Process Automation) selbstfahrende Potential als die wird 2022 Autos bis 2020 Dampfmaschine Mainstream - Forbes (2017) – McKinsey (2019) - Gartner (2019) 11 Ist serverless = autonomous? Serverless ist die Abstraktion der Infrastruktur und des Betriebs, das Provisionierung, Skalierung, Wartung u.a. inkludiert Der Betrieb der Infrastruktur ist automatisiert & wird vom Provider bereitgestellt. Autonomous Services = autonome Dienste kennzeichnen sich durch den hohen Automatisierungsgrad aus, der Nutzer braucht sich nicht um Betrieb & Wartung des Services kümmern, z.B.: AWS Lambda, Azure und Oracle Functions, Oracle Autonomous Database Services 12 Anwendungsszenarien / Einsatzgebiete 13 Allgemeine Anwendungsfälle – “Führe Code als Antwort auf Events aus” Glue Cloud Web, Mobile, IoT Real-time File, DevOps, Batch Services, Event- Backends Stream Processing driven Processing 14 Cloud Infrastructure Event-Driven Architekturen ORACLE CLOUD Network DB / DW DB / DW Audit Events Functions Trigger Storage functions Compute Storage Functions can use DB, Storage, and other services 15 Functions als Klebstoff für Cloud Services Cloud Applications (SaaS) Cloud Platform (PaaS) ERP HCM Supply Chain Mobile Data Mgmt Custom Apps Functions Business Data Analytics CX Integration Insight Collaboration Cloud Infrastructure (IaaS) Network Compute Storage Audit Events 16 Bedarf an Persistenz im Serverless Umfeld Persistence allows containers to “remember” - Mechanisms for persistence: API call Functions with Persistence Autonomous Database Benefits • Fully managed, self tuned database • Complete infrastructure automation Oracle Function • Consolidation and standardization: multi modal polyglot • Security: automated patching/updating • Interoperable with any development, data integration, analysis and reporting tool • Multitenant, pluggable architecture Object Block File Autonomous Database Storage Storage Storage Block, File Storage Benefits • Durable Oracle Cloud Infrastructure Oracle Cloud Infrastructure storage, external to Functions • Enable scalable and resilient architecture • Dynamic provisioning 17 Lösungen mit Oracle Functions & Autonomous DB entwickeln 18 Zweck & Nutzen von Oracle Functions Pay Per Use Pay for execution, not for Oracle Functions idle time Functions-as-a- Service Oracle Cloud Autonomous Integrated Platform auto-scales Container Native functions No servers to provision, Open Source Engine manage Multi-tenant No Lock-in Secure Built on open-source Project and Docker 19 Fn Project im Überblick ✅ Open Source—no vendor lock-in ✅ Platform Independent—laptop, server, cloud ✅ Approachable—easy for new users, low level controls for advanced users ✅ Docker Based—leverage Docker ecosystem ✅ Scheduler Independent—deploy to Kubernetes, Swarm, Mesos, etc. http://fnproject.io or https://github.com/fnproject 20 Was ist eine Fn Function? • Small chunk of code wrapped into a container image with all dependencies • Fn server passes in function input and environment • Fn server returns results to caller • STDERR automatically routed to logs • Various development kits to develop a function availlable • Simple Fn Debugging by sending messages to syslog log server & using OpenTracing metrics The Fn server handles everything else, like the API gateway, piping things around, storing logs, etc. 21 Fn Plattform Architektur 22 Fn Function Request Flow 23 Fn CLI fn init --runtime go fn create app myapp fn deploy --app myapp fn invoke myapp myfunc → http://localhost:8080/t/myapp/myfunc 24 Fn Function deployen 1.Builds container (multi-stage) + bumps version 2.Pushes container to registry 3.Creates/updates function & triggers (fn servers lazy load images) 1 2 3 Your code Fn Service myfunc → /t/myapp/myfunc:0.
