Troy Hunt is an Australian security professional who has a lot of knowledge on security and data breaches. He is well known for his free service Have I Been Pwned? which aggregates data breaches so that users can find out if their credentials have been leaked. Also, he has developed another service to see which passwords have ever been leaked, so that you might check your (or your users’) passwords to see if they’re safe enough to use.
Consequently, he publishes a lot about the development of said services and all the organizational and technical snags he has hit, for example how he found out that many cloud instances spawned almost overnight to handle an ‘unexpected’ rise of new requests. After his analysis he explained how he redesigned the service so that the vast amount of users could be serviced without him having to pay humongous fees.
