Design principles
In addition to the general design principles from the cost optimization pillar of the Well-Architected Framework whitepaper, the following design principles can assist you to optimize the costs of your telco network infrastructure.

Measure cost at every layer of the network infrastructure: The costs to develop, operate, and maintain the network have significant impact on the financial viability of a telco. Therefore, it is important to understand and track the infrastructure costs at each layer - core, distribution, access, edge - so you can identify areas that may require cost optimization.
