Docker & CoreOS - Part 2

Engineeringby Rob Holland on September 12, 2015

In Part 1 [https://clearbit-blog.ghost.io/blog/servers-part-one] of this series we gave you an overview of the deployment process at Clearbit. In this post I'm going to talk about our how we use fleet to run our services. > Note: We use Amazon's EC2 system. In this article when I refer to a machine I'm really talking about an EC2 instance. I've used machine to avoid confusion with an instance (runnning process) of an application. Life before Fleet Before migrating over to CoreOS/Fleet we were

Docker & CoreOS - Part 1

Engineeringby Alex MacCaw on July 20, 2015

We use Docker and CoreOS extensively at Clearbit. We have over 70 different internal services running across a cluster of 18 machines on EC2.

We've made significant upfront investments into tools to help us with this and we'd like to share our experiences to help other teams facing similar ch

I'm happy to announce we've released a new data attribute for our Company API - technology tags. These tags represent the technology stack and products used by a company. This can be quite handy. We love instantly knowing whether a new signup comes from a business that already leverages cloud technology or not. In addition, it helps us be more targeted with messaging as to our prebuilt integrations (ex. someone uses Salesforce). For example the tech tags for segment.com [https://segment.com] s

Versioning APIs Internally

Engineeringby Alex MacCaw on June 02, 2015

One reason behind this is that the implementation is often a mess, a nestled spaghetti of conditional statements littering your codebase that usually looks something like this: if params[:version] == 1 show_something else show_something_else end At Clearbit we'
