We do think that our tech blog is full of interesting things powered by our engineers' great stories. Let me take you on a journey of how we maintain the trivago tech blog from the technical perspective and how we recently automated its deployment process.

When I joined trivago a year ago, we had problems with our releases. The traffic was increasing each day. When we put the server back into the load balancer without warming up the OPcache it would die. From time to time the warmup failed silently. Our DCO (data center operations) crew had to log into the servers and restart a few processes manually. During this time every release was very intense.
