CDN, Edge & DNS Calculators
20 free cdn, edge & dns calculators in Cloud.
- Anycast Coverage CalculatorCheck per-location load on an anycast prefix and whether the survivors absorb the traffic when a location withdraws.
- API Response Latency CalculatorBreak an API response into DNS, TCP, TLS, server and transfer time, then project the p95 and p99 tail.
- CDN Bandwidth CalculatorSize CDN and origin bandwidth from visitors, page weight and a peak-to-average ratio instead of a monthly average.
- CDN Cache Hit Ratio CalculatorTurn edge hits and misses into a cache hit ratio, origin offload and the origin egress the cache actually avoids.
- Cloud DNS TTL CalculatorSee how a DNS TTL trades resolver cache hit ratio and query spend against how fast a record can fail over.
- Cloud Readiness Assessment CalculatorScore how ready an estate is for cloud and edge delivery, then estimate migration waves and elapsed months.
- Cloudflare CDN Cost CalculatorEstimate a Cloudflare bill from plan fee, Argo smart routing and the origin egress that caching still leaves behind.
- Cloudflare R2 Storage CalculatorCompare R2's zero-egress storage plus Class A and Class B operation charges against S3 storage plus per-GB egress.
- Cloudflare Workers Cost CalculatorPrice Cloudflare Workers on requests plus CPU milliseconds and check whether the free daily allowance still covers you.
- DNS Propagation Time CalculatorWork out the worst-case time a DNS change takes to reach every resolver, including the TTL you lowered beforehand.
- Edge Compute Cost CalculatorCost an edge function platform on per-million requests plus CPU milliseconds, after the allowances your plan includes.
- Edge Location PlannerWork out how many edge locations a latency target needs, from the distance budget the speed of light allows.
- Edge Performance Score CalculatorScore an edge delivery setup on cache efficiency, tail latency, reliability and protocol adoption, then rank the weakest.
- Edge Storage CalculatorSize and cost cached data at the edge, including the replication amplification of pushing hot objects to every location.
- Geo-Replication CalculatorSize cross-region replication bandwidth, storage and transfer cost from a daily change rate and compression.
- Global Latency CalculatorEstimate round-trip latency from distance using the speed of light in fibre, plus per-hop and processing overhead.
- Global Load Balancer CalculatorDerive failover time from health-check interval, failure threshold, DNS TTL and draining, and price the DNS queries.
- Regional Failover CalculatorTest whether surviving regions absorb the load when one fails, and price the standby capacity that makes it possible.
- Regional Traffic Distribution CalculatorSplit monthly traffic across world regions, find the busiest one and size its peak bandwidth from the share.
- Traffic Routing CalculatorSplit traffic across weighted origin pools and see the blended latency, plus what happens when a pool drops out.
