Cost Optimization and Resource Efficiency Questions

Approaches for balancing performance, reliability, and cost when designing and operating networks and cloud connectivity. Topics include modeling total cost of ownership, rightsizing bandwidth and equipment to avoid over provisioning, using caching and content delivery networks to reduce transit costs, traffic engineering to lower expensive links, evaluating capex versus opex tradeoffs, vendor and hardware selection for cost effective capacity, cloud specific cost controls such as reservation and committed use models, tagging and cost allocation, and monitoring cost drivers to drive continuous optimization. Candidates should be able to explain tradeoffs, justify cost conscious design decisions, and demonstrate how to achieve required service levels with efficient resource usage.
