For us it was a lot of simple things. Change management was the biggest pain but in the end it was just an extra step in our build process.<p>Our canary process was a bit hands on (find a host, deploy to that host, tcpdump&#x2F;check logs to validate the changes were correct and in effect). We stopped doing that. I can&#x27;t decide if we are building better software without that as a crutch or if we are just not seeing production issues.<p>Anyway, it&#x27;s stuff like that. Little shortcuts here and there. Nothing major, but it required behavioral change within the org.
