We talk about when it’s appropriate to use segregated services/different servers per service or to use consolidated services.



Starts at 19m53s.

I was drinking water. Paden was drinking water. Jthan was drinking Left Hand’s Oktoberfest Märzen Lager.

  • When should you segregate/isolate services to their own server or combining services into one server?
    • Some key questions: What services might need to share information? What services would work better together on a localhost? Where would it make sense from a security standpoint to share a local socket (e.g. “UNIX socket”) instead of a network socket?
    • Jthan specifically had questions about whether it was better to use a separate DB server from the webservers or keep the DB on the same box as the webserver
    • I mention that virtualization (see S2E12) is a good compromise between the two.
    • DEFINITELY isolate onto separate physical boxes when 1.) virtual limits, etc. aren’t enough for what you need and the box is maxed out (assuming you’re using virtualization), and 2.) high-risk security concerns (i.e. airgapping)

Sysbadministration Award

In this segment, we highlight system administration mistakes. Think of them as the IT equivalent of the Darwin Awards. (38m30s)

GitHub, the monolith souce code hosting service “too big to fail”, tanked for an hour and had a huge effect on individuals and businesses everywhere.
