The evolved Comprehensively Unified ICT Architecture can be modelled as a “Classic Saucer Champagne Glass” with:
A wide Flat Bottom Base depicting the multitude of Field Devices & sensors etc.
The Saucer Shaped Bowl on the Top depicting being filled with an ever-increasing spectrum of Digital Infrastructure Applications and diverse relevant Services
The Long Stem depicts all the Common Layers viz.: the Unified Last Mile Communication, Common Standardized Gateways, Common Service layer representing the Common Service Functions and the Digital Infrastructure Middleware & Data Reservoir in the Cloud.
It is the “Long Stem” of the “Champagne Glass Model” instead of the Short & Narrow Neck in the “Hourglass Model” that brings the comprehensive harmonization, standardization & interoperability in the Architecture leading to optimization in operational efficiency & Life Cycle Cost of the ICT Infrastructure in any Digital Infrastructure.
This Architecture Model, beyond reducing significantly, the CAPEX, OPEX & Carbon Footprint of the Digital Infrastructure, enables a unified & well architected Infrastructure that can be easily designed to be comprehensively Resilient & Cyber Secure.
