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 build everything in-house. We put together this guide to help you choose the product that’s the best fit for your business.

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


AWS Database Migration Service (DMS)

DMS supports simple preload schema and tablespace transformations: rename, remove column, convert case, add or remove prefix or suffix, and define primary key. Transformations are defined in JSON format.


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.

AWS Database Migration Service (DMS)

DMS supports about 10 types of database sources and destinations, including both cloud and on-premises databases. Cloud database sources may be a database managed by the customer running on Amazon EC2, or a managed service such as Microsoft Azure SQL Database, Amazon RDS, or Amazon S3. DMS doesn't support any SaaS data sources.


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.

AWS Database Migration Service (DMS)

AWS provides online support through a ticketing system and a knowledgebase. Support tickets may get phone or chat responses. Documentation is comprehensive. Digital training materials are available.


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.


AWS Database Migration Service (DMS)

DMS pricing, like all AWS pricing, depends on instance size and storage amounts. Instances are charged by the hour and storage by the month.


Stitch has pricing that scales to fit a wide range of budgets and company sizes. All new users get an unlimited 14-day trial. After the trial, there's a free plan for smaller organizations and nonproduction workloads. Standard plans range from $100 to $1,250 per month depending on scale, with discounts for paying annually. Enterprise plans for larger organizations and mission-critical use cases can include custom features, data volumes, and service levels, and are priced individually.
