Install Azure Data Factory self-hosted integration runtime to ingest from on-premises data systems. The goal is to show an end-to-end solution, leveraging many of these technologies, but not necessarily doing work in every component possible. The lab architecture is below and includes:.
WideWorldImporters WWI imports a wide range of products which then resells to retailers and public directly. In an increasingly crowded market, they are always looking for ways to differentiate themselves, and provide added value to their customers. They are looking to pilot a data warehouse to provide additional information useful to their internal sales and marketing agents.
They want to enable their agents to perform AS-IS and AS-WAS analysis in order to price the items more accurately and predict the product demand at different times during the year. Also to extend their physical presence WWI is extending their business by and recently acquired a medium supermarket business called SmartFoods which their differentiating factor is their emphasis on providing very comprehensive information on food nutrients to customer in order for them to make health wise decisions.
SmartFoods run their own loyalty program which customer can accumulate points on their purchases. The portal will be showing aggregated information on customers important food nutrients Carbs, Saturated fats etc.
In this hands-on lab, attendees will build an end-to-end solution to build a data warehouse using data lake methodology. Below is a diagram of the solution architecture you will build in this lab. Please study this carefully so you understand the solution as whole, before building various components. Hands on lab documents are located under Lab-guide directory. Here is the list labs available:.

Note: This is a work in progress and any feedback and collaboration is really appreciated. However, the differences in querying, modeling, and data partitioning mean that MPP solutions require a different skill set. Azure Synapse formerly Azure SQL Data Warehouse can also be used for small and medium datasets, where the workload is compute and memory intensive.
Read more about Azure Synapse patterns and common scenarios:. Are you working with extremely large data sets or highly complex, long-running queries? If yes, consider an MPP option. For a large data set, is the data source structured or unstructured? They can output the processed data into structured data, making it easier to load into Azure Synapse or one of the other options.
For structured data, Azure Synapse has a performance tier called Optimized for Compute, for compute-intensive workloads requiring ultra-high performance. Do you want to separate your historical data from your current, operational data? If so, select one of the options where orchestration is required. These are standalone warehouses optimized for heavy read access, and are best suited as a separate historical data store. Do you need to integrate data from several sources, beyond your OLTP data store?
If so, consider options that easily integrate multiple data sources. Do you have a multitenancy requirement? If so, Azure Synapse is not ideal for this requirement. Do you prefer a relational data store? If so, choose an option with a relational data store, but also note that you can use a tool like PolyBase to query non-relational data stores if needed.
If you decide to use PolyBase, however, run performance tests against your unstructured data sets for your workload. Do you have real-time reporting requirements? If you require rapid query response times on high volumes of singleton inserts, choose an option that supports real-time reporting. Do you need to support a large number of concurrent users and connections? SQL Server allows a maximum of 32, user connections.
When running on a VM, performance will depend on the VM size and other factors. Azure Synapse has limits on concurrent queries and concurrent connections. For more information, see Concurrency and workload management in Azure Synapse. Consider using complementary services, such as Azure Analysis Services , to overcome limits in Azure Synapse.
What sort of workload do you have? In general, MPP-based warehouse solutions are best suited for analytical, batch-oriented workloads.
One exception to this guideline is when using stream processing on an HDInsight cluster, such as Spark Streaming, and storing the data within a Hive table. Attach an external data store to your cluster so your data is retained when you delete your cluster. You can use Azure Data Factory to automate your cluster's lifecycle by creating an on-demand HDInsight cluster to process your workload, then delete it once the processing is complete.
Snapshots start every four to eight hours and are available for seven days. When a snapshot is older than seven days, it expires and its restore point is no longer available. Standard backup and restore options that apply to Blob Storage or Data Lake Storage can be used for the data, or third-party HDInsight backup and restore solutions, such as Imanis Data can be used for greater flexibility and ease of use.

Table of contents. Data warehousing in Microsoft Azure Synapse Analytics. Data warehouse architectures The following reference architectures show end-to-end data warehouse architectures on Azure: Enterprise BI in Azure with Azure Synapse Analytics. When to use this solution Choose a data warehouse when you need to turn massive amounts of data from operational systems into a format that is easy to understand. Other benefits include: The data warehouse can store historical data from multiple sources, representing a single source of truth.
You can improve data quality by cleaning up data as it is imported into the data warehouse. Reporting tools don't compete with the transactional systems for query processing cycles. A data warehouse allows the transactional system to focus on handling writes, while the data warehouse satisfies the majority of read requests. A data warehouse can consolidate data from different software.
