# Talks

## The Road to 150+ TB clusters by Loïc Dumont (Pictet)

For the past five years, we have been managing two Elasticsearch clusters to collect logs and metrics across our data centers. In this talk, we will present you the evolution of our clusters from the beginning to today and our plans for the future. We will also talk about the different challenges related to running big clusters.

## REX: 3 years in PROD with ElasticSearch as main and cache data store by Sylvain Laurent (Pictet)

After living more than 3 years in Production with ES, the Digital Platform team has a few stories to tell: production operations, data loading strategies, data modeling choices, automated integration tests, Java/Spring client applications, choosing between MongoDB and ES... This presentation will NOT be about new features or best practices with the latest ES version, but rather day-to-day practices and choices of a small development team that has been using ES for its applications.

We hope to see you there!
