Most businesses have data stored in a variety of locations, from in-house databases to SaaS platforms. To get a full picture of their finances and operations, they pull data from all those sources into a data warehouse or data lake and run analytics against it. But they don't want to build and maintain their own data pipelines.

Fortunately, it’s not necessary to code everything in-house. Here's an comparison of three such tools, head to head.

About CloverDX

CloverDX (formerly CloverETL) is a data integration platform for designing and running data jobs through a graphical user interface.

About Azure Database Migration Service

Azure Database Migration Service is a managed service designed to enable migrations from multiple database sources to Microsoft Azure data platforms. The service uses Microsoft's Data Migration Assistant to generate assessment reports that provide recommendations to guide you through the changes required. When you're ready to begin the migration process, Azure Database Migration Service performs all the required steps.

Stitch and Talend partner closely with Microsoft. While this page details our products that have some overlapping functionality and the differences between them, we're more complementary than we are competitive. Microsoft Azure offers lots of products beyond what's mentioned on this page, and we have thousands of customers who successfully use our solutions together.

Let's dive into some of the details of each platform.

Transformations

CloverDX

CloverDX (formerly CloverETL) provides a wide variety of pre-load transformations through a drag-and-drop interface. Developers can modify or write transformations using Java or CloverDX Transformation Language (CTL).

Azure Database Migration Service

Azure Database Migration Services does no transformation. DMS is intended to be a simple way to do easy migrations, such as from on-premises SQL Server to Azure SQL Database, or MySQL to Azure Database for MySQL, or MongoDB to Azure Cosmos DB.

Stitch

Stitch is an ELT product. Within the pipeline, Stitch does only transformations that are required for compatibility with the destination, such as translating data types or denesting data when relevant. Stitch is part of Talend, which also provides tools for transforming data either within the data warehouse or via external processing engines such as Spark and MapReduce. Transformations can be defined in SQL, Python, Java, or via graphical user interface.

Connectors: Data sources and destinations

Each of these tools supports a variety of data sources and destinations.

CloverDX

CloverDX supports fewer than 20 data sources. Most are various filetypes; databases and Hadoop are also supported. It can write data to databases and files, but it supports no data warehouses or data lakes.

Azure Database Migration Service

Azure Database Migration Service integrates with 10 on-premises database sources and six Azure database destinations, but no data warehouse or data lake destinations.

Stitch

Stitch supports more than 100 database and SaaS integrations as data sources, and eight data warehouse and data lake destinations. Customers can contract with Stitch to build new sources, and anyone can add a new source to Stitch by developing it according to the standards laid out in Singer, an open source toolkit for writing scripts that move data. Singer integrations can be run independently, regardless of whether the user is a Stitch customer. Running Singer integrations on Stitch’s platform allows users to take advantage of Stitch's monitoring, scheduling, credential management, and autoscaling features.

Support, documentation, and training

Data integration tools can be complex, so vendors offer several ways to help their customers. Online documentation is the first resource users often turn to, and support teams can answer questions that aren't covered in the docs. Vendors of the more complicated tools may also offer training services.

CloverDX

CloverDX provides support through email and an online ticketing system. Documentation is highly technical. The company provides in-person training services.

Azure Database Migration Service

Azure Database Migration Service provides support via online forums and an online support request form. Email and phone support are available. Documentation is comprehensive. Digital training materials are available.

Stitch

Stitch provides in-app chat support to all customers, and phone support is available for Enterprise customers. Support SLAs are available. Documentation is comprehensive and is open source — anyone can contribute additions and improvements or repurpose the content. Stitch does not provide training services.

Pricing

CloverDX

CloverDX pricing is undisclosed.
