Ask HN: “Software Testing execution on cloud” future?

Hey, I wanted to discuss the product fit one solition. Whether this is real world problem or not.

Software testing is moving on cloud, market is divided into two segment right now. Tools/framework for automation testing and when you build test suit, you need cloud to execute it.

There are tools like browserstack, saucelabs, Jmeter etc.

My questions are as follows:

1.) Do you really see test execution is real problem because setting up test infrastructure in house is expensive?

2) Do you really see you need to execute your tests on different browser, OS and devices? is this blocker in your test process?

How big you think cloud test execution market could be?
