● Introduction
● What is CEP ?
● CEP with Canopsis

3. 3
An event is a piece of data that represents that
something happened in the real world, or in
software system.
e.g UserClick, ServiceFailure, BellsRinging
Event

4. 4
Complex Event
An event that could only happen when lots of
other events happen.
e.g Wedding is happen, etc.

5. 5
What is CEP ?
Complex Event Processing (CEP) is a set of
techniques and tools to help understand and
control event-driven Information System.

Processing Models
● Batch processing
● (Event-) Stream processing
● Micro-batching

10. 10
CEP with canopsis
● Fast memory processing of events (filtering,
grouping and aggregating)
● Real time analysis
● Better scaling of the infrastruture
● Flexibility to use query language to monitor
