Apr 7Don’t follow the sun: Scheduling compute workloads to chase green energy can be counter-productiveWe want to reduce carbon emissions of our compute and storage workloads, and one way of doing this is to choose a time and place where the “grid mix” of energy consumed is less carbon intensive. In particular, there is usually an excess of solar energy during the day that…Sustainability4 min readSustainability4 min read
Apr 5Proposal for a Realtime Carbon Footprint Standardby Adrian Cockcroft The existing approaches to carbon measurement provide delayed data for carbon accounting that is more akin to billing information in the way it is structured and queried. This proposal seeks to define a standard for real-time carbon and energy data as time-series data that would be accessed…AWS7 min readAWS7 min read
Feb 14Sustainability at AWS re:Invent 2022 -All the talks and videos I could find…This blog post is long overdue — I spent too long trying to find time to watch all the videos, and finally gave up and listed a few below that I haven’t seen. The keynotes didn’t feature anything new on carbon, just re-iterated the existing path to 100% green energy…AWS7 min readAWS7 min read

Jan 29Percentiles don’t work: Analyzing the distribution of response times for web services (Updated with code)Most people have figured out that the average response time for a web service is a very poor estimate of it’s behavior, as responses are usually much faster than the average, but there’s a long tail of much slower responses. The common way to deal with this is to measure…Rstats12 min readRstats12 min read
