Cobbler and Chef in Ety's provisioning stack

Dec 10, 2013 7:00 pm
Dec 10, 2013 8:15 pm

At Etsy automation is important and necessary to keep up with our fast-paced infrastructure that is rapidly growing. We need to be able to scale our systems as quickly as possible. Keeping in mind that our production stack exclusively runs on physical hardware. The old way of provisioning servers worked at the time, but now that we have over 1,000 servers it was time to revisit our host provisioning methods. Various tools where developed to create a "1-click" host build solution, Chef & Cobbler are a big part of the process.

In this talk I'll introduce InfluxDB, a distributed time series database we open sourced based on our backend infrastructure at Errplane. I'll talk about why you'd want a database specifically for time series data and cover the API and some of the key features of InfluxDB, including:
* Stores metrics (like Graphite) and events (like page views, exceptions, deploys)
* No external dependencies (self-contained binary)
* Fast. Handles many thousands of writes per second per server
* HTTP API for reading and writing data
* SQL-like query language
