Meltdown and Spectre did a real number on the c5 and m5 instance types.

Amazon's original fix reduced performance substantially, which lot's of people noticed, but no one knew why till the vulnerabilities were announced.

Meanwhile Google built a clever workaround which minimized the pain. It was really a mic-drop moment from Google and I wish someone would dig in deep and tell the whole story.

At this point I'm sure AWS has merged Google's patches, but it showed how much Google was investing in their GCP offerings.

It is less to do with Google investing in GCP offerings than their investment in general in Operating Systems and their sheer quality of engineers.

Which I am sure will also work at Amazon or have worked at Amazon.

Unlikely.

Interesting! Do you know of any resource where I can read more about this?

The tech is called Retpoline, and this blog has some pointers: https://www.blog.google/topics/google-cloud/protecting-our-g...

There was a few interesting bits in a post the other days about their new compute VM class, #4 in particular https://cloud.google.com/blog/products/compute/understanding... Its pretty light on details but was news to me.

This is not related to Spectre/Meltdown, which was over a year ago.
