Modernization/Dockerization Hazards Enablement

Despite Digital Transformation and application modernization being well established practices, there are always unforeseen issues the creep up. This exceedingly truncated list of hazards will hopefully help identify some issues early.

💡 This is a companion to -- not a replacement for -- the decadeds of retrospective material that exists on the subject. While it's advisable to engage an outside consultancy if you're unfamiliar with the topic, tackling this list early can offset those costs as their runbook will contain similar content as they assess your application.
