When Tricentis GmbH closed its massive $165 million funding round earlier this year, Chief Executive Officer Sandeep Johri suggested that some of the capital may go toward strategic acquisitions. The first such deal is now officially in the bag.

The Vienna, Austria-based software testing provider said today it has picked up a startup called Flood IO Pty Ltd. that helps companies check how their applications scale. Ensuring that a service can efficiently accommodate an increase in usage is simultaneously one of the most difficult and most important items on enterprise development teams’ checklist. It’s a particularly big priority when it comes to web services, which in some cases must serve upwards of millions of users per month.

Flood IO’s namesake service enables teams to evaluate if an application is up to the task using tools they’re already familiar with. An engineer can create an assessment workflow with one of the several popular testing frameworks that the startup supports, upload the code to its platform and let the execution engine under the hood take care of the rest. 

Flood IO will run the workflow in cloud instances spread across multiple Amazon Web Services data centers, which makes it possible to simulate web traffic from different regions. The results are displayed in a visual dashboard that provides a detailed view of how the application handles the load. It’s refreshed in near-real-time to let developers quickly pause the test and start troubleshooting if an issue crops up.

More than 5,000 companies use Flood IO in their software projects, including Bloomberg LP, AT&T Inc., Red Hat Inc. and numerous other big names. Tricentis is set to absorb all of these customer accounts as part of the deal alongside the startup’s technology, which will be integrated into its flagship Continuous Testing platform. The Flood IO team is set to come aboard as well to support feature development efforts.

The financial terms of the deal were not disclosed.
