Balancing act: the current limits of AWS network load balancers<\/a><\/div>\n
\n

This well-researched article caught me by surprise. It\u2019s shocking that Ably received advice from AWS to stay under 400,000 simultaneous connections, despite Amazon\u2019s own documentation<\/a> stating support for \u201cmillions of connections per second\u201d.<\/p>\n

\n
\n

This blog is about how a group of hard-working individuals, with unique skills and working methods, managed to create a successful SRE team.<\/p>\n<\/blockquote>\n

Frequently Asked Questions on Deviations<\/a><\/div>\n
\n

There\u2019s a nice little discussion of why \u201chuman error\u201d is not a good enough answer for why a deviation (from standard operating procedure) happened.<\/p>\n

How To Get Fooled By Metrics<\/a><\/div>\n
\n

They deployed an optimization that skipped sending some requests to the backend\u2026 and the backend metrics got worse. Why? Hint: aggregate metrics.<\/p>\n
