– Streaming or Speed layer is responsible for processing live streaming data without any persistence of data in the storage area. Here processing of data takes place when it is in motion. This layer activates when data comes in or with specific short time interval and subsequently generates the real-time view which gets pushed to next layer (Servicing Layer)
– Eventually, in this layer called Serving Layer, we get combined results from both streaming layer and batch layer which can be effectively utilized to provide unified desired results. Here always we will get the update from the batch layer and streaming layer either periodically or in real-time.
Lambda Architecture is a pluggable architecture where to process on demand, we can plug-in and plug-out the various number of data generation sources.
