Travis Downs explores a recent Intel microcode update that may have negatively impacted performance. Via Alex Mitelman’s Systems Design Weekly 015 , I was pointed to this AWS article on multi-site active-active architectures. It’s a good starting point for thinking about operating your own active-active architecture.
