Data warehouse with Microsoft Azure & Snowflake
Faster time to market often drives companies of all sizes to move their legacy data warehouse applications to the cloud. Other factors include Scalability, Increased security, cost reduction, enhanced operations, and elasticity. However, all these benefits could be neutralized by the biggest challenge Information Technology (IT) departments face, namely, choosing the best path to moving legacy data warehouse applications to the cloud.
For many large organizations though, it is the go-to tool to utilize their data effectively. It’s not a matter of whether you go to the cloud to manage your enterprise data, but how and when are the critical questions.
In this article, we highlight some of the key benefits of building a modern Data Warehouse on Microsoft Azure using Snowflake and benefits of moving your Enterprise Data Warehouse (EDW) to the cloud and how you can get the process started.
Why Modernize Data Warehouse?
For many large organizations, Enterprise Data Warehouses (EDWs) are their lifeblood which supports a variety of workloads, including financial reporting, customer satisfaction analysis, manufacturing quality, shipping & logistics, as well as ad hoc workloads from individual business units. This ability to support so many fields makes EDW the go-to tool for any organization looking to employ their data efficiently.
Although many organizations still have their EDWs based on site, there is a growing inclination for moving this data to the cloud. As operational data volumes continue to grow at exponential rates, this gives rise to service-level expectations, and the need to integrate structured warehouse data with unstructured data in a data lake becomes greater.
Here are some critical points due to which enterprises are increasingly thinking to modernize their data warehouse:
The benefits of a cloud-based data warehouse
Having a cloud-based data warehouse simplifies time-consuming and costly management, administration, and tuning activities that are typical of on-premises data warehouses. But beyond these obvious advantages, there’s more to be gained from moving to the cloud. Some of the key advantages of a cloud-based data warehouse are listed below.
Building a Modern Data Warehouse on Microsoft Azure using Snowflake
The first question one might get is - why build Data warehouse with Microsoft Azure & Snowflake? First, let’s get this answered.
Microsoft Azure: It is a modern intelligent cloud platform by Microsoft having a plethora of Platform and infrastructure services embracing Windows and Open Source ecosystems and capable of catering all the Public and Hybrid Cloud enterprise scenarios. It is one of the most secure, compliant with industry norms and standard and most trustworthy cloud when it comes to storing your data.
Snowflake: It is an analytic data warehouse provided as Software-as-a-Service (SaaS). Snowflake provides a very flexible & faster data warehouse which is more user-friendly than any other traditional data warehouse offerings.
Lifecycle of Modern Data Warehouse on Microsoft Azure
In the enterprise applications scenario, we see lot of data getting stored in different forms and features. In the era of Artificial Intelligence and predicative analysis using Machine Learning (which is a subset of AI), we need large, scalable, secure, robust and highly available, on demand data stores.

Data Services in Microsoft Azure
Modern data and analytics estate can transform business with five verticals having a complementary Microsoft Azure services to it.
What is Snowflake and how it helps to modernize your data warehouse?
Snowflake is a data warehouse-as-a-service which provides complete relational database support for both structured data, such as CSV files and tables, and semi-structured data, including JSON, Parquet, etc., all within a single integrated solution. It does not require any management and features separate as compute, storage, and cloud services that can scale and change independently.
Around July 12, 2018, Snowflake announced its availability on Microsoft Azure Cloud Platform as DWaaS (Datawarehouse-as-a-Service). Snowflake is now offered in Azure as a cloud computing option to run Snowflake’s cloud-built data warehouse.

You can also have Azure Active Directory Integration to manage your account and Sign-on for Snowflake. Read additional information here for integrating Azure AD with Snowflake.
Building Visualization over Snowflake Datawarehouse using PowerBI
Power BI is a business analytics solution (Power BI Desktop & Power BI service) that lets you visualize your data and share insights across your organization or embed them in your application or website. Through Power BI, you can connect to hundreds of data sources and bring your data to life with live dashboards and reports. Most users who work on Business Intelligence projects use Power BI Desktop to create reports, and then use the Power BI service to share their reports with others.
To connect PowerBI Desktop to Snowflake you need to install the Snowflake ODBC driver on your PowerBI Desktop machine. Once installed, you can use the built-in Snowflake data source for PowerBI. To connect to a Snowflake computing warehouse, select Get Data from the Home ribbon in Power BI Desktop. Select Database from the categories on the left, and you see Snowflake.
