There are quite a few different data warehouse technologies to choose from, and knowing where to start, what to look for, and what data warehouse service is going to be best for your business is key. Deciding on a data warehousing technology that is suitable to your business needs, goals and objective is essential as it will have long-term implications, whether that’s positive or negative.
In this article, we will look at the two leading data and cloud computing technologies offered by the biggest names in technology. Azure SQL and AWS Redshift are two technologies which are popular when architecting data warehouses. Ardent’s engineers are proficient in both have delivered several data warehousing projects for clients using these leading technologies.
Azure SQL is a managed Data Warehouse-as-a Service (DWaaS) provided by Microsoft. It acts as a federated repository for data, which is collected by a business’s operational systems. The architecture of the data warehouse is based on the latest general release of the SQL server, and can be used by data analysts, data scientists, and end-users to run queries, process information, and examine metric data.
There are a number of benefits and limitations of using Azure SQL for warehousing your data. Benefits:

Redshift is an Amazon product that provides a petabyte (PB) scale data warehouse service that operates with cloud technology. The warehouse service is fully managed and can be scaled to allow growth for new insights and customers. Based on PostgreSQL, the platform offers a high level of flexibility and can integrate with most third-party platforms with its JDBC and ODBC drivers.
Each technology has a number of key benefits and some limitations you should consider.

When looking at Azure SQL and AWS Redshift for data warehousing, your specific data needs, database set-up, operational requirements, and familiarity with the platforms, will largely influence how you make your decision.
Scalability
There are lots of elements to consider, for example, when it comes to scalability, Redshift cluster modification is done through a management console or an API, with the changes immediately applied. With the Azure SQL data warehouse, scaling of clusters can be done through compute and storage units independently and can take minutes to be applied.
Indexing
For Indexes, Azure supports all SQL concepts (indexes, stored procedures, user-defined functions), whereas Redshift supports two kinds of sort keys (compound and interleaved).
The differences between the two platforms are largely in functionality and operation, which can make deciding a challenge if you are not familiar with the intricacies involved, and seeking expert advice and assistance is highly recommended.
