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.
