vCPU →Core-Hours
16 vCPUs × 730 hours = 11,680 core-hours/month. 200 instances = 2.3M core-hours. Reservation planning, quantified.
vCPU Accumulator →K8s milliCPU →Cores
4,500m = 4.5 cores. 20 pods/node, each requesting 500m = 10 cores. You're overcommitted 2.2:1. No wonder CPU throttling fires at 2 AM.
milliCPU Converter →K8s Pod Density & Bin Packing
16 vCPU, 64 GB, 110 pod ENI limit. Your app: 2 GB/pod. Memory bottleneck hits at 32 pods —long before CPU or ENI. Find the real constraint.
Pod Density Calculator →Lambda Execution Cost
5M invocations × 200ms × 1024MB. Lambda bills in 1ms increments. The free tier ends, the bill begins. Project the monthly burn rate before your function goes viral.
Lambda Cost Projector →Serverless Ephemeral Storage
10 GB /tmp × 50 concurrent invocations = 500 GB provisioned. Every GB over the free tier is $0.0000000309/GB-ms. It adds up. Run the tally.
Ephemeral Storage Meter →ALB Rule Latency Inspector
80 rules. 0.2—.5ms each. 16—0ms added latency —before the first byte reaches your backend. Count your rules before you burn your latency budget.
ALB Latency Inspector →Kafka Partition →Broker RAM
1,200 partitions. ~10 MB overhead each. 12 GB JVM heap —before producer buffers. Size the broker or watch the OOM killer punch in at peak ingest.
Kafka RAM Profiler →NAT Gateway Cost →Full Bill
$0.045/hr idle charge before a byte moves. 3 AZs = $98.55/mo in hourly alone. Data processing at $0.045/GB. Cross-AZ double-counting. Model vs VPC Endpoint replacement.
NAT Gateway Cost Engine →Managed DB Cost →RDS vs Aurora vs Cloud SQL
Compare AWS RDS, Aurora, Google Cloud SQL, and Azure DB monthly: compute, storage, provisioned IOPS, Multi-AZ HA, read replicas, backup retention, committed-use discounts. The managed-DB bill isn't one number.
Managed DB Cost Engine →S3 Lifecycle Cost Estimator →Storage Tier TCO
Compare 4 lifecycle strategies: All Standard vs IA →Glacier Instant/Flexible/Deep Archive. Model transition costs, minimum-duration penalties (30-180 days), 128 KB object floor, Glacier retrieval fees, and 3-year TCO with 2026 us-east-1 pricing.
