Everyone's localhost is an environment

A few days ago, I asked how many pre-production environments you have for your software application.

But did you include each Developer's local environment?

Each developer will have a development environment - either on their computer or a development server - to write and initially test their code before it's deployed to a test, staging or production environment.

Here's the thing

Each Developer's local or development site is an environment too.

They also need to be easily updatable and consistent with the other environments, but they are often overlooked or forgotten.

When was the last time you or your Developers updated your local environment?
