In this workshop you will learn about the main concepts related to advanced analytics and Big Data processing and how Azure Data Services can be used to implement a modern data warehouse architecture. You will learn what Azure services you can leverage to establish a solid data platform to quickly ingest, process and visualise data from a large variety of data sources. The reference architecture you will build as part of this exercise has been proven to give you the flexibility and scalability to grow and handle large volumes of data and keep an optimal level of performance.
In the exercises in this lab you will build data pipelines using data related to New York City. The workshop was designed to progressively implement an extended modern data platform architecture starting from a traditional relational data pipeline. Then we introduce big data scenarios with large data files and distributed computing. We add non-structured data and AI into the mix and finish off with real-time stream analytics. You will have done all of that by the end of the workshop.
The workshop can be completed on your own pace depending on your previous experince with the Azure DP tools. Supporting slides are available for each format.

IMPORTANT:
-
The reference architecture proposed in this workshop aims to explain just enough of the role of each of the Azure Data Services included in the overall modern data platform architecture. This workshop does not replace the need of in-depth training on each Azure service covered.
-
The services covered in this course are only a subset of a much larger family of Azure services. Similar outcomes can be achieved by leveraging other services and/or features not covered by this workshop. Specific business requirements may require the use of different services or features not included in this workshop.
-
Some concepts presented in this course can be quite complex and you may need to seek more information from different sources to compliment your understanding of the Azure services covered.
Microsoft recently announced Azure Synapse Analytics as the evolution of Azure SQL Data Warehouse, blending big data, data warehousing, and data integration into a single service for end-to-end analytics at cloud scale. This reference architecture and workshop content will be updated as announced features in the roadmap become publicly available.

Throughout a series of 5 labs you will progressively implement a modern data platform architecture using datasets from New York City.
You will start ingesting relational data about motorvehicle collisions in Manhattan hosted in an Azure SQL Database into your Azure Synapse Analytics data warehouse. Then we will introduce the concepts of data lake and big data challenges and you will put these into practice by ingesting and processing over 50 million yellow taxi ride records stored as large data files stored in your data lake.
You will then use Databricks and the power of Spark clusters to explore big data files. Then you will incorporate AI into your data pipeline by invoking the Cognitive Services Computer Vision API to automatically generate metadata for New York City street photographs and store the metadata in a Cosmos DB database. Finally, you will use a LogicApp to simulate high-frequency stock purchase transactions as a source of streaming events that you will capture, store and process in real time with Event Hubs, Stream Analytics and Power BI.
By the end of the workshop you will have implemented the lab architecture referenced below:
IMPORTANT: You should skip this Lab if you are executing the labs through subscriptions provided by CloudLabs. All Azure services will be deployed as you activate your registration.
In this section you will automatically provision all Azure resources required to complete labs 1 though to 5. We will use a pre-defined ARM template with the definition of all Azure services used to ingest, store, process and visualise data.
The estimated time to complete this lab is: 30 minutes.
| IMPORTANT |
|---|
| In order to avoid potential delays caused by issues found during the ARM template deployment it is recommended you execute Lab 0 prior to Day 1. |
In this lab, the dataset you will use contains data about motor vehicle collisions that happened in New Your City from 2012 to 2019 stored in a relational database. You will configure the Azure environment to allow relational data to be transferred from an Azure SQL Database to an Azure Synapse Analytics data warehouse using Azure Data Factory also staging to Azure Data Lake storage. You will use Power BI to visualise collision data loaded from your Azure Synapse data warehouse.
The estimated time to complete this lab is: 45 minutes.
| Step | Description |
|---|---|
 |
Build an Azure Data Factory Pipeline to copy data from an Azure SQL Database table |
 |
Use Azure Data Lake Storage Gen2 as a staging area for Polybase |
 |
Load data to an Azure Synapse Analytics table using Polybase |
 |
Visualize data from Azure Synapse Analytics using Power BI |
In this lab the dataset you will use contains detailed New York City Yellow Taxi rides for the first half of 2019. You will use Azure Data Factory to download large data files to your data lake. You will generate a daily aggregated summary of all rides from data lake using Mapping Data Flows and save the resulting dataset in your Azure Synapse Analytics. You will use Power BI to visualise summarised taxi ride data.
The estimated time to complete this lab is: 60 minutes.
| Step | Description |
|---|---|
 |
Build an Azure Data Factory Pipeline to copy big data files from shared Azure Storage |
 |
Ingest data files into your data lake |
 |
Use Mapping Data Flows to generate a aggregated daily summary and save the resulting dataset into your Azure Synapse Analytics data warehouse. |
 |
Visualize data from your Azure Synapse Analytics using Power BI |
In this lab you will use Azure Databricks to explore the New York Taxi data files you saved in your data lake in Lab 2. Using a Databricks notebook you will connect to the data lake and query taxi ride details for data cleasning and to apply standard column definitions for the resulting dataset. At the completion, The resulting dataset should be saved in a Spark table using Parquet files sitting in the NYCTaxiData-Curated container in your SynapseDataLake storage account.
The estimated time to complete this lab is: 45 minutes.
| Step | Description |
|---|---|
 |
Build an Azure Databricks notebook to explore the data files you saved in your data lake in the previous exercise. You will use Python and SQL commands to open a connection to your data lake and query data from data files. |
 |
Integrate datasets from Azure Synapse Analytics data warehouse to your big data processing pipeline. Databricks becomes the bridge between your relational and non-relational data stores. |
In this lab you will use Azure Data Factory to download New York City images to your data lake. Then, as part of the same pipeline, you are going to use an Azure Databricks notebook to invoke Computer Vision Cognitive Service to generate metadata documents and save them in back in your data lake. The Azure Data Factory pipeline then finishes by saving all metadata information in a Cosmos DB collection. You will use Power BI to visualise NYC images and their AI-generated metadata.
The estimated time to complete this lab is: 75 minutes.
| Step | Description |
|---|---|
 |
Build an Azure Data Factory Pipeline to copy image files from shared Azure Storage |
 |
Save image files to your data lake |
 |
For each image in your data lake, invoke an Azure Databricks notebook that will take the image URL as parameter |
 |
For each image call the Azure Computer Vision Cognitive service to generate image metadata. Metadata files are saved back in your data lake |
 |
Copy metadata JSON documents into your Cosmos DB database |
 |
Visualize images and associated metadata using Power BI |
In this lab you will use an Azure Logic App to simulate a NYSE stream of stock purchase transactions. The logic app will then send the messages to Event Hubs. You will then use Stream Analytics to receive and process the stream and perform aggregations to calculate the number of transactions and amount traded in the last 10 seconds. Stream Analytics will send the results to a real-time dataset in Power BI.
The estimated time to complete this lab is: 45 minutes.
| Step | Description |
|---|---|
 |
Review the Azure Logic App logic that simmulates the NYSE transaction stream sent to EventHubs |
 |
Save simulated NYSE stock transaction messages into your data lake for future analysis (cold path) |
 |
Send stream of NYSE stock transaction messages to Stream Analytics for real-time analytics (hot path) |
 |
Incorporate Stock Company reference data into your stream processing logic |
 |
Visualize real-time data generated by Stream Analytics with Power BI |
