Revenue 0,5 Bill. EBITDA adjusted Employees Datenbasis Finanzzahlen: DT Geschäftsbericht 2017

4 IoT Is Not a Product! Manufacturing Aerospace & Defence Energy & Utilities Agriculture Industrial Internet Automotive & Transport Healthcare Others Retail

5 Typical IoT Architecture Industry Utilties Automotive Wisdom Applications Health Home Enablers LPWA complex and fragmented! API Knowledge Platforms LTE-M LTE Cat-O LTE Cat-1 Information Protocols Cellular IoT SW16 Weightless-P Connectivity Data Factory Physical Devices (or things) Weightless-N Machina Research 10

6 Technical challenges: Different Real-time Req. Building technology, control and automation levels, trouble-free processes, storage systems Conveying systems, simple controls, majority of all automated systems 3GPP 2G, 3G, and LP WAN Machine tools, fast processes, robots 3GPP 4G and 5G Highly dynamic processes, electronic drives 1 ms 10 ms 100 ms 1 s 10 s Response time / jitter Source: Industrial Ethernet Facts, Feb 2013

7 Integration Challenge In 80% of cases 50% of the budget is for integration Increasing number of vendors and products Increasing solution complexity Enterprise Cloud Platforms Edge Platforms IoT Gateway IoT Sensors and actuators Enterprise Applications ERP CRM BM FSM MES Data Center and / or Cloud Cloud Platforms Public / Private / Hybrid / On-Premise Standard Cloud Services and IoT Unique Cloud Services Edge Platforms Cloud Clone, Hybrid Cloud and Distributed IoT Services IoT Gateways Network and Protocol Translation, Data Aggregation IoT Endpoints Connected Assets with Sensors, Compute & Communication Source: Gartner - The Business Impact of IoT

8 Other Aspects Architectural Style: Monolithic vs. Micro-Services Interaction Model: client/server vs. Synchronous/Asynchronous Distributed Integration: REST vs. Message-Passing Performance and scalability Technology Architecture: virtualization vs. Container

9 Control and Communication Towards Micro-service architecture INDUSTRIAL INTERNET REFERENCE ARCHITECTURE Functional Domains Business CRM, EPR, Billing & Payments, etc. Operations Prognostics Optimization Monitoring & Diagnostics Information Analytics Application API & UI Provisioning & Deployment Management Data Logic & Rules Executor Modelling & Data processing Entity abstraction Asset Management Communication Actuation/sensing How to integrate these functional components in a micro-service architecture?

10 Message Broker Approach Backbone for asynchronous processing and communication between different distributed components Queuing Producers put messages in a queue and each message can be polled by only ONE receiver. Message is removed from the queue after consuming Publish & subscribe Producers publish messages to dedicated topic Many receivers can subscribe to the topic to receive a copy of each published messages Other features Delivery guarantees Sending and acknowledgement of multiple messages in a single local transaction Durability: messages will be persisted Supporting several protocols and APIs
