AWS Services Provide Advanced Monitoring and Analytics of tcVISION’s Mainframe CDC Processing

by Joseph Brady, Director of Business Development and Cloud Alliance Leader at Treehouse Software, Inc.


Many Treehouse Software mainframe modernization customers have requirements for continuous near-real-time replication of mainframe data in order to keep a copy of the data synchronized on the Cloud. These customers are using tcVISION from Treehouse Software for changed data capture (CDC) for this synchronization, which allows changes occurring in any mainframe application data to be tracked and captured, and then published to a variety of AWS targets, including Amazon Simple Storage Service (S3). Some of these customers are also now asking us to recommend the best Cloud-based tools and methods to monitor and gain insights to these complex data processes. Coincidentally, while working with a current tcVISION customer, our technicians are testing out two particularly good, fully managed AWS services that can work hand-in-hand to address this need:

Amazon Athena

Since tcVISION supports Amazon S3 as a target, customers modernizing their mainframe systems on AWS can use Amazon Athena for monitoring and analysis of CDC processing from an S3 bucket.

Amazon Athena is a serverless, interactive analytics service built on open-source frameworks, supporting open-table and file formats. Athena provides a simplified, flexible way to analyze data from an S3 Bucket, as well as many other data sources, including on-premises data sources or other Cloud systems. Athena is built on open-source Trino and Presto engines and Apache Spark frameworks, with no provisioning or configuration effort required.

Amazon QuickSight


Once Athena is setup for monitoring an S3 Bucket, users can easily view their CDC processing and analytics with Amazon QuickSight. QuickSight utilizes advanced machine learning-powered insights and intuitive dashboards, so end users can make the best and quickest data-driven business decisions.
