Editor’s note: Contained in this blog, we examine just how German matchmaking app LOVOO left the monolith program getting a microservices frameworks, pushed in part by the completely handled, scalable Cloud Spanner.
We have now utilize up to 170 employees away from more than twenty five regions, which have practices in Dresden and Berlin. LOVOO changes mans life of the modifying how they satisfy. I do that courtesy creative place-based algorithms, a software radar element, and you will real time online streaming that will help somebody look for effective fits compliment of chat and you will real-time films.
Three years ago, i come to stumble on expanding vexation. Our very own associate feet is actually broadening on a reliable clip, as well as their craft from inside the application try growing also.

I performed an elevator-and-move migration of one’s structures, however, used the migration as the a catalyst so you’re able to modernize while making important transform. We separated some responsibilities in the monolith for the microservices, moving them myself to Yahoo Kubernetes Engine (GKE). We started out by the converting in the 12 functions in the monolith on the microservices, and you may our company is now around more forty microservices that we now have split on the earlier monolith.
I performed this new migration effortlessly in this a six day schedule, while we wanted to become inside date remaining for the all of our on-properties deals. I’ve intends to sooner or later move totally to help you a good microservices-oriented structures, however, we are bringing they a stride at the same time.
