To give some context I believe that AWS operates 69 availability zones(data centers). AWS wouldn’t be able to match the architecture scale of ZScaler.

You must be seriously kidding or that's pretty naive. Amazon CloudWatch monitors exponentially more end-points (of course all of that is within AWS environment) than ZScalar.

ZS has more data centers to avoid latency, but do not confuse Amazon's architecture scale with ZS. Just to be clear, what ZS calls a DC could be bunch of servers hosted in co-lo space, and not a true DC. Just look at the assets on the balance sheet or the fixed asset purchase on the cashflow statement, you can recognize that. For fiscal 2019, fixed asset purchase is $25m, on the other hand a typical data center would require about $1B investment for AWS.
