Docker: Light and Dark!Tori Wieldt !Developer Advocate!@ToriWieldt!



§  OS-level virtualization §  NOT Microservices

(but they go together well) §  NOT the cloud

(but is often run there) §  New Relic has been using Docker in

production for two years

Docker



Product Overview!



What can containers provide? §  Faster: code to production §  Better: manage in production §  Better: developer productivity §  Cheaper: better resource utilization

§  “Docker gets you to ask the right questions”

Docker : The Light



Speed §  “It worked on my laptop” goes away §  Standing up a dev environment takes much less time §  Launching a container 6x faster than a VM Reliability §  Forces you to know every dependency §  Identical running containers in case of failure Better Utilization §  4-6x better server util than VMs

Docker : The Light



Product Overview!



It Takes Time §  Dependencies! §  All those env variables Pioneering Days §  Docker is a moving Target §  Docs are written for greenfield

Had to Learn §  Containers will fail §  Noisy neighbors issues §  Have you set a memory limit?

Docker : The Dark



Not Ideal State (yet) §  Takes time to get dev environment set up §  Not self-serve for devs to deploy §  Still have to create Runbooks §  Security – processes can escape!
