IoT Architecture - are traditional architectures good enough or do we need new approaches?

Independent of the source of data, the integration of event streams into an Enterprise Architecture gets more and more important in the world of sensors, social media streams and Internet of Things. Events have to be accepted quickly and reliably, they have to be distributed and analysed, often with many consumers or systems interested in all or part of the events. Dependent on the size and quantity of such events, this can quickly be in the range of Big Data. How can we efficiently collect and transmit these events? How can we make sure that we can always report over historical events? How can these new events be integrated into traditional infrastructure and application landscape? Starting with a product and technology neutral reference architecture, we will then present different solutions using Open Source frameworks.

- 6. 2014 © Trivadis Data as an Asset - Store Anything? But then data is just too valuable to delete! We must store anything! Nonsense! Just store the data you know you need today! It depends … but Big Data technologies allow to store the raw information from both new data sources as well as existing ones so that you can later use it to create new data-driven products, you would not have thought about today! 6 19.11.2014 IoT Architektur
- 7. 2014 © Trivadis Requirements for an IoT Architecture • Support for failure • systems should gracefully degrade into lower performing states • If a failed component recovers, it should be able to rejoin the cluster • Recoverability • In the event of a failure, no data should be lost • Consistency • Failure of one task should not affect the result of the entire job • Scalability • Adding load leads to a decline of performance, not failure • Increasing resources results in proportional increase in capacity • Scale-up but also scale-down => elasticity 7 19.11.2014 IoT Architektur
