Discovery is as hard as naming, meaning still a complicated problem in large infrastructure. Many systems exists, but few outside a given ecosystem. Pierre and his Team have been using HashiCorp's Consul at large scale for several years (more than 250k services on 35k+ machines in 9 datacenters), and improving it until being the first external contributors to it (more than 70 merged upstreams contributions). It is now the common repository of all systems: included in all of their apps as well as within the deepest parts of the infrastructure which mixes low-latency workloads as well as one of biggest Hadoop Clusters in the world.
During this Lightning Talk Pierre will share with you how they learnt on how relying on a global discovery can leverage new ways of uncoupling infrastructure from code. They call this Inversion of control: all the organization can now push and retrieve semantics to create new services easily:
Automatic weighted Load-Balancing
New cross-applications features
This new way of creating semantics free the SRE as well as the whole company from tools and allow the whole organization be be more agile and innovative.

Pierre Souchay started in development and software architecture. He founded a company of audio/video encoders before joining a public cloud company as the main software architect. He is now working on building new architecture for infrastructure and leading a team responsible for Consul at Criteo, a large Consul user with more than 250k services on 35k nodes. Pierre is also the author of consul-templaterb, a high-performance templating program similar to consul-template, and is a maintainer of diplomat, a ruby gem to interact with Consul in Ruby. Pierre and his team are also significant contributors to Consul, working hard to improve its performance and scalability.
