03Why iones
How we choose a technology
The right technology is the one that serves your project in five years’ time, not the one that is talked about this year.
The need first
We start from your context: the team in place, budget, expected traffic, hosting constraints. The technology comes after.
Widespread standards
Widely adopted, well-documented technologies that are easy to recruit for: your project depends neither on a rare tool nor on us.
Tested before being proposed
Every new technology goes through our internal lab, with a protocol and measurements, before it reaches a client project.
Continuous upskilling
Technology watch, training and sharing between teams: our foundation evolves with the market, without giving in to fashion.
