Network Events: Basic Assumptions

Most are Garbage and they aremaaaany… • A relentless flood with very erratic

flow speeds.• Most tell you very loudly about a past

success… • …but you want the silent outlier, that

tells you about (hopefully) a futurefailure.

They are a Byproduct… • ...of a service delivery process. • Worst case, their creation consumes

resources for service delivery…• … and they are never „complete“. • Raw Data needs to be processed and

enriched to become usefulinformation…

Path to a Solution: Process First, Store Later, if at all.

• Streaming, not storing• In memory processing• Avoid redundant collection of data

from devices• Avoid redundant Polling from

Devices• Serve Unchanged Data from

Caches

• Store only what‘svaluable and worthkeeping

Foundation: Actor Model, akka and Scala

• An actor is a class in Scala or Java• Actors exchange messages, completely non-blocking. • Resilience by Design on the Principles of the Reactive

Manifesto. • Actors and Streams allow building simple and

powerful systems that easily scale up and out. • Elastic and Decentralized• High Performance – small footprint• Reactive Streaming Data.
