This week’s barrage of quarterly financial reports culminated after the stock market close last night with disclosures by three of the biggest names in tech: Alphabet (formerly known as Google), Amazon, and Microsoft.

While Google still doesn’t talk much about the growth of its cloud computing services (or any other discrete business for that matter), the other two companies are happy to do so. Maybe because the numbers look pretty good.

Exhibit A: Microsoft’s cloud division, which reflects sales for its Azure server and storage capacity on demand service, is now on an annual run rate of $8.2 billion. That’s double the previous year.

Technically speaking, you’ll notice that number is more than the $7.3 billion annual run rate that fierce rival Amazon Web Services hopes to reach shortly. But the two companies run on different fiscal calendars, which makes it tough to compare the projections directly. Microsoft just disclosed its first quarter results, while AWS just reported Q3. And based on its latest quarter, one in which AWS showed a $521 million profit, it looks like the cloud computer leader will surpass its full-year estimates. Expect more leapfrogging in the months to come.

This is my last day helming this newsletter. Adam Lashinsky, editorial director of Fortune Brainstorm Tech and the magazine’s most senior editor for technology coverage, steps in next Monday to reshape its mission.

I’ll still be a regular contributor on the Fortune Tech team, doubling down on my coverage of business software applications. I’m particularly keen on technologies that improve workplace collaboration, guide decision-making, or redefine the complex relationships between businesses and their customers.

I’d like to thank each of you for helping quadruple Data Sheet’s subscriber reach in the 14 months since its August 2014 launch. To quote the late Steve Jobs: “If today were the last day of your life, would you want to do what you are about to do today?” For me, the answer is an unequivocal “Yes.” I hope you all can say the same. Have a super Friday and enjoy the weekend!
