At the end of 2018, I told you the story of one of the BlaBlaCar Foundation teams' greatest success, "100% Containers Powered Carpooling". That conference was about our migration into containers, and described a paradigm that became key for us: every component of the infrastructure can be restarted at any time without impacting the applications using them.

In 2019 a new chapter had to be written, BlaBlaCar signed a contract with Google Cloud Platform and like many companies, we were starting our journey to the cloud… Eight open source database softwares, one hundred clusters, and a new infrastructure with new components, patterns, and tons of possibilities.

Building the team, finding the right focus, choosing tradeoffs, making or buying systems, changing our communication, proposing migration paths… With the Engineer Manager's hat, I will share with you what ingredients we had to look for to turn this massive project into a success story.
