Extract ServiceNow data using AWS Glue Studio in an Amazon S3 data lake and analyze using Amazon Athena

Many different cloud-based software as a service (SaaS) offerings are available in AWS. ServiceNow is one of the common cloud-based workflow automation platforms widely used by AWS customers. In the past few years, we saw a lot of customers who wanted to extract and integrate data from IT service management (ITSM) tools like ServiceNow for various use cases:

  • Generate insight from data – When you combine ServiceNow data with data from other services like CRM (such as Salesforce) or Martech data (such as Amazon Pinpoint) to generate better insights (e.g., building complete customer 360 view).
  • Archive data for future business or regulatory requirements – You can archive the data in raw form in your data lake to work on future use cases or just keep it to satisfy regulatory requirements such as auditing.
  • Improve performance by decoupling reporting or machine learning use cases from ITSM – When you move your ITSM reporting from ServiceNow to an Amazon Simple Storage Service (Amazon S3) data lake, there is no performance impact on your ServiceNow instance.
  • Data democratization – You can extract the data and put it into a data lake so it can be available to other business users and units to explore and use.

Many customers have been building modern data architectures on AWS, which includes building data lakes on Amazon S3 and using broad and deep AWS analytics and an AI/ML services to extract meaningful information from data by combining data from different data sources.

In this post, we provide a step-by-step guide to bring data from ServiceNow to an S3 data lake using AWS Glue Studio and analyze the data with Amazon Athena.

Solution overview

In this solution, ServiceNow data is being extracted through AWS Glue using a Marketplace connector. AWS Glue provides built-in support for the most commonly used data stores (such as Amazon Redshift, Amazon Aurora, Microsoft SQL Server, MySQL, MongoDB, and PostgreSQL) using JDBC connections. AWS Glue also allows you to use custom JDBC drivers in your extract, transform, and load (ETL) jobs. For data stores that are not natively supported, such as SaaS applications, you can use connectors and stored in Amazon S3. The data is cataloged in the AWS Glue Data Catalog, and we use Athena to query the data.

AWS Glue is a serverless data integration service that makes it easy to discover, prepare, and combine data for analytics, machine learning (ML), and application development. AWS Glue provides all the capabilities needed for data integration so you can start analyzing your data and put it to use in minutes instead of months.

Amazon Athena is an interactive query service that makes it easy to analyze data in Amazon S3 using standard SQL. Athena is serverless, so there is no infrastructure to manage, and you pay only for the queries that you run.

ServiceNow is a cloud-based software platform for ITSM that helps to automate IT business management. It’s designed based on ITIL guidelines to provide service orientation for tasks, activities, and processes.

The following diagram illustrates our solution architecture.

To implement the solution, we complete the following high-level steps:

  1. Subscribe to the AWS Glue Connector Marketplace for ServiceNow from AWS Marketplace.
  2. Create a connection in AWS Glue Studio.
  3. Create an AWS Identity and Access Management (IAM) role for AWS Glue.
  4. Configure and run an AWS Glue job that uses the connection.
  5. Run the query against the data lake (Amazon S3) using Athena.


For this walkthrough, you should have the following:

  • An AWS account.
  • A ServiceNow account. To follow along with this post, you can sign up for a developer account, which is pre-populated with sample records in many of the ServiceNow objects.
  • ServiceNow connection properties credentials stored in AWS Secrets Manager. On the Secrets Manager console, create a new secret (select Other type of secrets) with a key-value pair for each property, for example:
    • Username – ServiceNow Instance account user name (for example, admin)
    • Password – ServiceNow Instance account password
    • Instance – ServiceNow instance name without https and

Copy the secret name to use when configuring the connection in AWS Glue Studio.

Subscribe to the AWS Glue Marketplace Connector for ServiceNow

To connect, we use the AWS Glue Marketplace Connector for ServiceNow. You need to subscribe to the connector from AWS Marketplace.

The AWS Glue Marketplace Connector for ServiceNow is provided by third-party independent software vendor (ISV) listed on AWS Marketplace. Associated subscription fees and AWS usage fees apply once subscribed.

To use the connector in AWS Glue, you need to activate the subscribed connector in AWS Glue Studio. The activation process creates a connector object and connection in your AWS account.

  1. On the AWS Glue console, choose AWS Glue Studio.
  2. Choose Connectors.
  3. Choose Marketplace.
  4. Search for the CData AWS Glue Connector for ServiceNow.

After you subscribe to the connector, a new config tab appears on the AWS Marketplace connector page.

  1. Review the pricing and other relevant information.
  2. Choose Continue to Subscribe.
  3. Choose Accept Terms.

After you subscribe to the connector, the next steps are to configure it.

  1. Retain the default selections for Delivery Method and Software Version to use the latest connector software version.
  2. Choose Continue to Launch.

  1. Choose Usage Instructions.

A pop-up appears with a hyperlink to activate the connector with AWS Glue Studio.

  1. Choose this link to start configuring the connection to your ServiceNow account in AWS Glue Studio.

Create a connection in AWS Glue Studio

Create a connection in AWS Glue Studio with the following steps:

  1. For Name, enter a unique name for your ServiceNow connection.
  2. For Connection credential type, choose username_password.
  3. For AWS Secret, choose the Secrets Manager secret you created as a prerequisite.

Don’t provide any additional details in the optional Credentials section because it retrieves the value from Secrets Manager.

  1. Choose Create connection and activate connector to finish creating the connection.

You should now be able to view the ServiceNow connector you subscribed to and its associated connection.

Create an IAM role for AWS Glue

The next step is to create an IAM role with the necessary permissions for the AWS Glue job. The name of the role must start with the string AWSGlueServiceRole for AWS Glue Studio to use it correctly. You need to grant your IAM role permissions that AWS Glue can assume when calling other services on your behalf. For more information, see Create an IAM Role for AWS Glue.

Attach the following AWS managed policies to the role:

    "Version": "2012-10-17",
    "Statement": [
            "Effect": "Allow",
            "Action": [
            "Resource": [
                "{secret name arn}"

For more information about permissions, see Review IAM permissions needed for the AWS Glue Studio user.

Configure and run the AWS Glue job
