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 ETL tool comparison guide to help you choose the product that’s the best fit for your business.

Overview

AWS Glue, Informatica, and Stitch are all popular platforms. Here's a side-by-side look at how they stack up against each other.

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

Transformations

AWS Glue

AWS Glue provides 16 built-in preload transformations that let ETL jobs modify data to match the target schema. Glue generates Python code for ETL jobs that developers can modify to create more complex transformations, or they can use code written outside of Glue.

Informatica

Informatica has been an on-premises product for most of its history, and much of the product is focused on preload transformations, which is an important feature when sending data to an on-premises data warehouse. Informatica includes a library of prebuilt transformations and the ability to build custom transformations using a proprietary transformation language.

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.

AWS Glue

AWS Glue supports AWS data sources — Amazon Redshift, Amazon S3, Amazon RDS, and Amazon DynamoDB — and AWS destinations, as well as various databases via JDBC. Glue can also serve as an orchestration tool, so developers can write code that connects to other sources, processes the data, then writes it out to the data target.

Informatica

Informatica provides Cloud Connectors for more than 100 applications and databases. The only cloud data warehouse destination it supports is Amazon Redshift. It also support Pivotal's Greenplum on-premises platform. The only data lake destination it supports is Microsoft Azure SQL Data Lake. Developers can create new connectors using Informatica Connector Toolkit.

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.

AWS Glue

AWS provides several levels of support. Free Basic support provides access to support forums. Develop support adds client-side diagnostic tools and guidance on how to use AWS products, features, and services together. Business and Enterprise plans add additional options. Documentation is comprehensive. Both digital training and classroom training services are available.

Informatica

Informatica provides three levels of support. Basic Success is available during business hours. Premium Success offers 24x7 support for Priority 1 cases. Signature Support offers 24x7 support for all cases. Documentation is comprehensive. The company offers training through Informatica University.

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

AWS Glue

AWS Glue ETL jobs are billed at an hourly rate based on data processing units (DPU), which map to performance of the serverless infrastructure on which Glue runs. For the AWS Glue Data Catalog, users pay a monthly fee for storing and accessing Data Catalog the metadata. The first million objects stored are free, and the first million accesses are free. A development endpoint provisioned to interactively develop ETL code is billed per second.

Informatica

Informatica has many products, each of which may have several optional components. The base version of Integration Cloud starts at $2,000 per month. The pricing of add-on tiers is undisclosed. Informatica provides a 30-day free trial for many of its products.

Stitch

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.
