ANG: FinOps: Saving 7k EUR/month by 5 minutes action

hen I am teaching about the cloud and especially when I am showing cost optimization, I am presenting an example of Troy Hunt Have I Been Pwned cost saving case. Troy by using Cloudflare as a caching solution and moving traffic outside of Azure, managed to reduce the cost of infrastructure below 1 USD per month. At the end of 2018, when he was describing this case, his page was supporting  141M monthly queries of 517M records. This is a brilliant example of how you should work with your cloud solutions.
