AWS WAF charges based on the number of web access control lists (web ACLs) that you create, the number of rules that you add per web ACL, and the number of web requests that you receive. There are no upfront commitments. AWS WAF charges are in addition to Amazon CloudFront pricing, the Application Load Balancer (ALB) pricing, and/or Amazon API Gateway pricing.
Pricing Example 1: AWS WAF without Managed Rules
Let’s assume you start using AWS WAF at the first of the month to protect eight CloudFront web distributions. For this example, we’ll create two web ACLs, one web ACL with four rules associated to six CloudFront web distributions, and another web ACL with six rules associated to two remaining CloudFront web distributions. The CloudFront web distributions are expected to receive 10 million requests per month in total.
Web ACL
Web ACL charge = # of web ACLs per month * $5
Total web ACL charge = 2 * $5 = $10
Rule
The price for a rule is $1 per month (pro-rated by the hour)
Rule charge = # of rules associated per month * $1
Total rule charge = (4 + 6) * $1 = $10
Request
The price for request is $0.60 per million
Request charge = # of requests per month (in millions) * $0.60
Total request charge = 10 million requests * $0.60 = $6.00
Total Monthly Bill
Total web ACL charge + total rule charge + total request charge = $10 + $10 + $6 = $26
Pricing Example 2: AWS WAF with Managed Rules
Let’s assume that in addition to the usage scenario in Example 1, you also start using a Managed RuleGroup provided by a Marketplace seller. Sellers charge different prices for different Managed RuleGroups, but for this example, we’ll assume the seller is charging $22 per RuleGroup per month, and $1.15 per MM Requests. This Managed RuleGroup is associated with both your web ACLs. The Amazon CloudFront web distributions are expected to receive 10 million requests per month in total.
You will continue to pay the $26 as per Example 1. In addition, you will also be charged as per below:
AWS WAF Charges
Rule
The price for a Managed Rule is $1 per month
Rule charge = # of rules associated per month * $1
Total rule charge = 2 * $1 = $2 (The Managed Rule is associated with two web ACLs)
AWS Marketplace Charges
RuleGroup
The price for a RuleGroup is set by the seller at $22 per month (pro-rated by the hour)
RuleGroup charge = # of RuleGroups associated per month * $22
Total RuleGroup charge = 2 * $22 = $44
Request
The price for request is $1.15 per million
Request charge = # of requests per month (in millions) * $1.15
Total request charge = 10 million requests * $1.15 = $11.50
Total Marketplace Monthly Bill
Total RuleGroup charge + total request charge = $44 + $11.50 = $55.50
