+# Gerrit at Google: Multi-master, Mutli-tenant
+
+This talk is about hosting Gerrit at Google, gives insights into our
+architecture and provides some metrics on scale. In addition, it presents
+findings from the recent switch of our load-balancing infrastructure and
+highlights pitfalls we encoutered.
+
+## Gerrit at Google
+
+* Multi-master/-tenant setup
+* Replication
+* Housing large projects like Android and Chromium
+* Some metrics on scale
+* Outages and root-causes
+
+## Load-balancing Git/Gerrit Traffic at Google
+
+* Sharding of hosts, projects and repositories across hundreds of serving tasks
+* Optimizing different caches
+* Load-balancing decisions and their impact on latency
+* What garbage collection means for load-balancing and vice-versa
+
+
+*[Patrick Hiesel, Google](../speakers.md#hiesel)*
