1) Choose languages that developers are familiar with, not the best tool for the job
2) Avoid microservices where possible, the operational cost considering devops is just immense
3) Advanced reliability / redundancy even in critical systems ironically seems to causes more downtime than it prevents due to the introduction of complexity to dev & devops.
4) Continuous integration seems to be a plaster on the problem of complex devops introduced by microservices.
5) Agile "methodology" when used as anything but a tool to solve specific, discrete, communications issues is really problematic
I think overall we seem to be over-complicating software development. We look to architecture and process for flexibility when in reality its acting as a crutch for lack of communication and proper analysis of how we should be architecting the actual software.
Is it just me?
