There once was a businessman, he came up with the project, took the accumulated money, hired friends to work, took an inexpensive programmer and created a website.
Long tried and the site began to make a profit. Earn money and released. And of course wanted to expand, and as I was searching for. He advised : " That you also, need a new design, cool framework taking highload, partitioning, anti- DDOS...".
He sent all the money on a super technology, new FrameWork, design, features, optimization.
And spend , spend, spend .... And orders didn't grow . That closed the project.
Idea: Any technology needed for something. Make an analyze before implementation.
"Technology - it's not a goal but a means. Growth and profit are goal."
Do not get fooled by technology, demand forecasts ROI.
