Google Cloud Workload-Placement-Guide

At trivago we operate a hybrid infrastructure of both on-premise machines and clusters on Google Cloud. Over time, we came up with a set of deployment guidelines for running our workloads as more and more of them are migrating to Google Cloud. These are not strict rules, but rather suggestions to best serve each team’s needs. Teams are meant to have full control over their workloads, but most of the time they “just want to run things” and do not have the time or resources to care much about managing the underlying infrastructure.

On a normal day, we ingest a lot of data into our ELK clusters (~6TB across all of our data centers). This is mostly operational data (logs) from different components in our infrastructure. This data ranges from purely technical info (logs from our services) to data about which pages our users are loading (intersection between business and technical data). At trivago,we use Kafka as a central hub for moving data between our systems (including logs).

To the outside, trivago appears to be one single software product providing our popular hotel meta search. Behind the scenes, however, it is home to dozens of projects and tools to support it. Teams are encouraged to choose the programming languages and frameworks that will get the job done best. Only few restrictions are placed on the teams in these decisions, primarily long-term maintainability. As a result, trivago has a largely polyglot code base that fosters creativity and diverse thinking.

Hello from trivago’s performance & monitoring team. One important part of our job is to ship more than a terabyte of logs and system metrics per day, from various data sources into elasticsearch, several time series databases and other data sinks. We do so by reading most of the data from multiple Kafka clusters and processing them with nearly 100 Logstashes. Our clusters currently consists of ~30 machines running Debian 7 with bare-metal installations of the aforementioned services.
