This article and interview contains more useful information about how to plan a move from monolith to microservices than a hundred grand spent with a consultant, and El Reg gave it to us for free.

GitHub's journey towards microservices and more: 'We actually have our own version of Ruby that we maintain'
90%? Erm, no. Just buy MailDroid and be done with it.
I used K-9 for three months and blasphemed at it daily. If you want a free Google mail client that's a bit better than the stock one, sure, use K-9. If you have to actually get work done, have multiple accounts with multiple clients and want your calendaring to work, buy MailDroid. MailDroid works with all versions of IMAP, POP3 and Exchange, including OWA, which K-9 doesn't do.
I have no affiliation with MailDroid, just an affiliation with not wasting time making an email app work.
