PLEASURE AND PAIN OF GROWTH

4

Started with a single webapp

Product organization evolving faster than system architecture

Teams themselves are responsible for breaking away

Sometimes Conway's Law needs a push

WHAT WE BELIEVE IN

5

Embracing Conway's law

Teams own the logic they touch the most

Weak ownership model

Full cycle ownership

No handovers - you own it, from idea to death

Rapid feedback from production

Fast iterations

Small changes are safer

Everyone can roll out independently

LIFECYCLE IN PRACTICE

DELIVERY PIPELINE

Jenkins (build, QA)Octopus / shell (deploy)

MONITORING

Rollbar (exceptions)New Relic (performance)ELK (detailed investigation)Zabbix (the rest)

ON-CALL

VictorOps (rotations + escalation)Slack (worktime alerts)SMS :)

6

LOT'S TO DO STILL

Breaking the monolith

Webapps still released centrally

How to do analytics across multiple datastores?

Service constellation

Number is growing, no dependency management yet

Getting new services live still has an overhead

Security

Security ownership with NO security office.

Integrating validation into delivery pipeline?

7

WHAT IS DEVOPS FOR TRANSFERWISE?

8

Platform team owns networking, shared persistence services

Something between IaaS/PaaS model

YOU BUILD IT

YOU RUN IT

Product teams are in full control of their systems' lifecycle

Everybody is involved

No Devops team

No Devops roles

AUTONOMOUS PEOPLE ARE HAPPY PEOPLEWe're hiring
