What is DevOps
DevOps (short for Development & Operations) is an agile methodology in softwaredevelopment and release.
DevOps is a culture applied to organisations aiming to bridge the gap between Devand Ops.

DevOps
DevOps: The PeoplePerHour case; before
Before adopting DevOps:
Tests were not maintained properly
Builds would ship untested
Development / Staging / Production environments not identical
Huge monolithic app
Systems/Ops a black box
Scaling needed planning and manual intervention
Metrics lacking
DevOps: The PeoplePerHour case; after
After adopting DevOps:
Tests run per Pull Request, per Build
Fully automated CI / CD pipeline
Infrastructure as Code
Development / Staging / Production environments are identical
Switching to a microservices oriented architecture, ready for scale. Following the12-factor app paradigm as close as we can
Proper central log aggregation and analysis
DevOps: The PeoplePerHour case; mission
Made big wins, now to make more profit:
Re-use our shiny SOA to bootstrap new products faster
Make DevOps team obsolete and replace it in favor of DevOps-as-a-culture
Create joined teams cross-organisation to tackle trivial problems
Make our former DevOps team a combat-mission team
DevOps: The PeoplePerHour case; Community
We joined forces with other startups to create a DevOps community in Athens.
Reach out to my team, we'd love to share stories and help eachother out in DevOpstransformation.
DevOps: Words of advise
To junior developers: If you can afford to: choose Tech, Workflows and Team oversalary. It will pay out in a couple of years. That doesn't mean low-balling yourself orlet bosses/seniors take advantage of you.
To senior developers: Combine techical ability with domain experience. Lift yourteam to your level. Speak up. Don't be a hero programmer. Get payed for the valueyou bring in. Embrace change.
To VPs and C-levels: Hire people smarter than you. Bet in teams and not in Heros.Let your engineers run the product as well; they know it, they've built it. UseDevOps
Creating a community; Why Athens DevOps?
