The power in your pocket:
On July 20, 1969, humans landed on the #moon. Key to that feat was a computer module designed by the @MIT Instrumentation Laboratory called the Apollo Guidance Computer

Not particularly powerful by todays standards having 64Kbyte of memory & operating at 0.043MHz but boy did it deliver on a complex task greater than the sum of its electronic parts, providing computation + electronic interfaces for guidance, navigation & control of the spacecraft
Even then, there were teams of technicians and engineers at the Goddard Space Flight Center using 5 @IBM System/360 Model 75s #mainframe computer to run parallel comparative calculations to ensure everything went right ... no room for error
Tinder moved to #Kubernetes and @EnvoyProxy, is averaging appx 50 containers, 15 pods per node. Interesting for a few reasons from my perspective
#1/ Bigger nodes running many containers is not so rare. At @signalfx we are seeing this more and more in the field. Is it too early to say that #Mainframe is making a comeback? #MillenialMainframe #GenerationM
#2/ "One reason we were able to move so quickly was due to the rich metrics we were able to easily integrate"
Seeing this everywhere. You can't fly a #jetplane without instruments and you can't run advanced #infrastructure without great #observability and #metrics

No one saw #NarrowPath? 🤔
