complex user interface. Because of this, most Git users end up being dabblers. They learn a few commands, the minimum number to be functional, and stop there. And yet, there is so much to be gained ...

As Quoin reimagines our website, we are also reimagining the infrastructure on which it runs.  Our original website uses two Amazon Elastic Compute Cloud (EC2) server instances - one each for the development and production environments, along with storage services and attendant Identity and Access Management (IAM) roles and policies. While this collection of services is functional, it is more than strictly necessary to run a containerized website. In the interest of greater efficiency, enabled ...

The House That Quoin Built


If websites were houses, then our house
