It is difficult to calculate the ROI of Compute Engine. Maybe if you combine it with other products, based on Compute Engine it would save a lot of money. For example, we use PCare and Looker for visualization. They are based on the Google Platform. If you use those two, you can save a lot of money that you would otherwise pay for IBM or Tableau.

We have seen ROI with the tool's use. 

I cannot quantify ROI, but our application's performance has improved since we moved from an on-prem to a cloud. So, that's one major ROI for us. We saw approximately 60 to 70% improvement.

The return on investment is good for Google Compute Engine because using this option, we can save more than 90% of the initial investment compared to alternatives. It's ideal for development and testing. In production, it can result in a saving of 60 to 70 percent when compared to other services.

At this point there is no ROI unless the business model fundamentally changes.

For the foreseeable future this will be a significant budget deficit.
