It’s time to get rid of the operating system

We’ve abstracted many things you and I.  But its time to crack the next nut.  Let me explain why. Bare Metal I started out managing applications on bare metal x86 and AIX servers.  In those days we were updating the operating systems to the latest releases, patching with security updates, and ensuring our dependencies were […]

Go with NX-API

I’ve been working on a project to collect data from Cisco Nexus switches.  I first tackled making SNMP calls to collect counter statistics but then I thought, why not try it with the NX-API that came with the Nexus 9ks? The documentation for the APIs I hoped would be better, but the samples on github […]

Continuous Delivery of a Simple Web Application Tutorial – Part 4
