Don’t just move the problem, solve it!
How many times have you found yourself emailing a sensitive file to your accountant, lawyer, friend, relative, or co-worker and immediately feeling remorseful? Or perhaps you uploaded the file to some cloud storage provider and emailed or Slacked the link. You have tried some password-based encryption programs only to find that they are buggy, hard to work with, and most importantly, don’t really solve the problem — they just move the problem from securely sharing the file to securely sharing the encryption password. You have been reading about all sorts of privacy and security breaches and your cynical alter ego has almost convinced you to give up on security. Sound familiar?

This specific blog describes a key challenge of configuration drift faced by an operations team when making configuration changes across a large number of clusters or sites.
