Why New Relic Loves Containers

Developers Are Productive Faster

Less Yak Shaving, More Coding

Streamlined Communications Between TeamsLess Handoffs Mean Less Errors

Better Than VMs

Containers Launch 6x Faster Than VMs

4-6 Times Better Utilization Than VMs

Why Ops Loves Containers

No More Racking / Kickstarting Pizza Boxes

Script What You Need

“Build once, run anywhere” for infrastructure

Much Less Fiddling With Puppet & Chef

Devs own those dependencies now!

Don’t Fix, Replace

Why Dev Loves Containers

Faster Provisioning

“I need a place to run a new app...” Done in minutes not weeks!

Control Of Runtime Environment

Dev owns exactly what the app gets

Redundancy Is “Easy”

Go N+2 and beyond; stripe across hosts

Microservices Friendly

One service per container
