Lambda architecture is a data processing technique that is capable of dealing with huge amount of data in an efficient manner. Let's look at the generic Lambda architecture first to get an idea of what is it trying to achieve. Lambda Architecture Rearchitected - Batch Layer, Lambda Architecture Rearchitected - Batch to Serving Layer, All data is pushed into Azure Cosmos DB for processing, The batch layer has a master dataset (immutable, append-only set of raw data) and pre-computes the batch views. Lambda architecture is used to solve the problem of computing arbitrary functions. From this point onwards, you can use HDInsight (Apache Spark) to perform the pre-compute functions from the batch layer to serving layer, as shown in the following figure: For code example, please see here and for complete code samples, see azure-cosmosdb-spark/lambda/samples including: As previously noted, using the Azure Cosmos DB Change Feed Library allows you to simplify the operations between the batch and speed layers. It is a Generic, Scalable, and Fault-tolerant data processing architecture to address batch and speed latency scenarios with big data and map-reduce. – Implement optimized storage for big data analytics workloads. Lambda architectures enable efficient data processing of massive data sets. Implement a Kappa or Lambda architecture on Azure using Event Hubs, Stream Analytics and Azure SQL, to ingest at least 1 Billion message per day on a 16 vCores database. The real-time processing layer must meet the following requirements: Ingestion: Receive millions of events per second Act as a fully managed Platform-as-a-Service (PaaS) solution Integrate with Azure Functions Stream processing: Process on a per-job basis A powerful, low-code platform for building apps quickly, Get the SDKs and command-line tools you need, Continuously build, test, release, and monitor your mobile and desktop apps. Batch layer (cold path): This layer stores all of the incoming data in its raw form and performs batch processing on the data. You are designing a new Lambda architecture on Microsoft Azure. The efficiency of this architecture becomes evident in the form of increased throughput, reduced latency and negligible errors. All All big data solutions start with one or more data sources. The data ingestion and processing is called pipeline architecture and it has two flavours as explained below. The Lambda Architecture stands to the fact that there's no single tool or technology in building robustness, fault-tolerant, scalable system that can produce analytics results close to real time.
