1. DON’T STOP BELIEVING Our Infrastructure as Code Journey at Paperless Post Bethany Erskine
2. A STARTUP IS BORN
4. TODAY 500 VIRTUAL SERVERS 135 EMPLOYEES 60 ENGINEERS 2 OFFICES IN 2 COUNTRIES 500K DAILY WWW VISITORS
5. PAPERLESS POST OPS 2016
6. Immutable Infrastructure
7. ZERO to INFRASTRUCTURE AS CODE
8. AN OPS TEAM IS BORN # Employee #35 Employee #36 (me!)
10. Ruby on Rails Postgres Redis Memcache Nagios and Munin A whole bunch of BASH scripts Gorilla Glue Hopes and Dreams 2011
12. PAPERLESS-CHEF DEPLOY WORKFLOW local git local devtools ON WORKSTATION pp chef deploy earth shining_star * tests cookbooks * bumps cookbook versions * tags branch & pushes back to github * triggers deploy on Jenkins jenkins devtools ON JENKINS pp chef deploy earth shining_star —local * checks out tag * uploads any changed cookbooks * uploads updated environment file chefserver
13. PAPERLESS-CHEF DEPLOY WORKFLOW Deploy to staging Pull Request Code Review! Deploy to Production

34. PAPERLESS APPLICATION DEPLOY WORKFLOW local git local devtools ON LOCAL: pp application deploy earth shining_star * tags branch & pushes back to github * triggers deploy on Jenkins jenkins devtools ON JENKINS: pp chef deploy earth shining_star —local * checks out tag * runs database migrations * deploys code to each node returned by Chef API query * restarts application on each node application servers SSH deployparty application servers application servers
36. PAPERLESS DOCKER 1.0
38. ~$ pp noderenderer deploy production fix_api_url
39. PAPERLESS DOCKER DEPLOY WORKFLOW local git ON LOCAL: git push origin shining_star pp application deploy earth shining_star * tags branch & pushes back to github * triggers deploy on Jenkins local devtools jenkins devtools ON JENKINS: pp chef deploy earth shining_star —local * checks out tag * runs docker build * pushes tagged docker build to quay.io * SSH into each node returned by Chef search and: * run docker pull * restart docker container via SystemD script application servers SSH deployparty application servers application servers quay.io

80. Ruby on Rails Javascript Postgres Redis Memcache Haproxy Elasticsearch Postgres Sensu Graphite & Grafana Filebeat/Elasticsearch/Logstash/Kibana Go Python NodeJS Vphere EC2 S3 Amazon RDS ELB Docker Terraform Hopes Dreams 2016
81. 2016 Terraformed full-stack services utilizing AWS, Docker and Chef ( vSphere nodes created with `pp chef create_node`
82. WHERE WE ARE NOT • Mature CHEF cookbook and role testing • Continuous Provisioning / Autoscaling • Continuous Terraform module testing
83. All the Way, Soon
