Cloud Storage: 6-Vendor Comparison
S3 at $0.023/GB. R2 at $0.015/GB —zero egress. The savings shift depending on your retrieval pattern. Run the matrix.
Compare 6 Vendors →DB Instance Spec Selector
MySQL at 5K QPS, 2KB rows →db.r6g.xlarge. MongoDB at same load →different math entirely. Cross-cloud mapping included.
Size DB Instance →Backup Strategy: 3-2-1 TCO
Local vs cloud vs hybrid. Cumulative storage growth modeled over 1/3/5 years. Don't discover your backup bill on month 36.
Model Backup TCO →Log Storage & Retention: Build vs Buy
Self-built ELK/Loki vs Datadog at $1.70/GB vs Splunk at $5/GB. Grafana Cloud in the middle. Full 1/3/5-year TCO.
Compare Log TCO →Data Migration: Timeline Planner
50 TB at 1 Gbps = 5.2 days best case. Now add protocol overhead, transfer windows, ongoing writes. Cutover planning, not wishful thinking.
Plan Migration →Latency Budget: End-to-End
3,000 km fiber = 15 ms propagation. Speed of light in glass = 5 μs/km. Add switch hops, serialization, queuing. Budget the RTT before you promise 50ms p99.
Budget Latency →Container Resource Limits: JVM / V8 / Go
Runtime-aware memory and CPU estimator. JVM heap ≥?container limit. V8 garbage collection spikes. Go GC pauses. OOM risk analysis per runtime.
Size Container Limits →API Rate Limit →Cost: Gateway Showdown
AWS API Gateway vs GCP Apigee vs Azure API Management vs self-hosted NGINX/Kong. Convert req/s into monthly cost. Egress modeling included.
Project API Cost →CDN Cache Hit: 5-Provider Impact
What's a 5% cache-hit improvement worth? Model CloudFront, Cloudflare, Fastly, BunnyCDN, KeyCDN. Origin offload × dollar savings, quantified.
Model CDN Impact →Datacenter PUE →Power Cost
PUE 1.6 at 500 kW IT load × $0.10/kWh = $58,440/month. Improve to PUE 1.2, save $14,610/month. Model cooling overhead at every tier.
Model PUE Cost →RAID Configuration: 0/1/5/6/10
Capacity. IOPS. Rebuild time. MTTDL. URE risk flagged for large drives where rebuilds exceed 24 hours. Compare all five levels simultaneously.
Compare RAID Levels →RI vs Spot: Breakeven Calculator
3-year RI commitment vs 65% spot discount. The breakeven hinges on one variable: interruption rate. Model the annual spread before you lock in 36 months.
