Big Data Lambda Architecture

Big Data Lambda Architecture• Batch layer• Stores master dataset• Compute arbitrary views

• Speed layer• Fast, incremental algorithms• Batch layer eventually

overrides speed layer

• Serving layer• Random access to batch

views• Updated by batch layer

Serving Layer

Speed Layer

Batch Layer

The Batch Layer

• Stores master dataset (in append mode)

• Unrestrained computation

• Horizontally scalable

• High latency

Incoming data

streamsMaster dataset

Batch views

The Speed Layer

• Stream processing of data

• Stores a limited window of data

• Dynamic computation

Real-time increments

The Serving Layer

• Queries the batch and real-time views

• Merges the resultsReal-time views

Demo 1: Setting up the Windows Azure storage account

Azure Storage Explorer

Azure Storage Explorer

Blob Storage Concepts• Store large amounts of

unstructured text or binary data with the fastest read performance

• Highly scalable, durable, and available file system

• Blobs can be exposed publically over HTTP

• Securely lock down permissions to blobs
