Installing and configuring Upsource on AWS with SSL

Upsource is a tool that brings Jetbrains IDE's code insights to code reviews. Upsource's integration with Jetbrains IDEs and GitHub are some of the most attractive features for us at VideoBlocks since we're heavy users of them both. We currently have over 50 private repos and use IntelliJ, PHPStorm and WebStorm to build our core products. All of our infrastructure is hosted on AWS now, so I decided to get this up and running there for quick evaluation.

Launch an EC2 Instance

This step is straight forward and there are already some good resources for setting up an EC2 instance. I won't go into detail here, but I chose an Ubuntu AMI at a size of M3.large (which is the minimum instance size Jetbrains recommends). We're configuring our security group with the standard HTTP ports (80 and 443) and exposing the standard SSH port 22.

Currently, there is an explosion of tools that aim to manage secrets for automated, cloud native infrastructure management. Daniel Somerfield did some work classifying the various approaches, but (as far as I know) no one has made a recent effort to summarize the various tools.

This is an attempt to give a quick overview of what can be found out there. The list is alphabetical. There will be tools that are missing, and some of the facts might be wrong--I welcome your corrections. For the purpose, I can be reached via @maxvt on Twitter, or just leave me a comment here.

There is a companion feature matrix of various tools. Comments are welcome in the same manner.
