Web-Scale IT Engineering.
Web-scale IT – modern description for the “web companies-like” enterprise datacentre architectural design.
Invented by industry leaders (Google, Facebook, Amazon, etc), used by the majority of the biggest enterprised today.
De facto – quiet revolution in the enterprise IT, changed the landscape dramatically. New leaders, older vendors losing the market.
Key principals – commodity hardware, software-defined everything, “human-less” architecture, scale-out instead of scale-up, “each hardware component will eventually fail”, micro-segmentation and microservices, hyper convergency – compute and data locality.
