AWS is nothing.
DataDog are the worst for this. Their salespeople are like stereotypes of 80s user car salesmen.
AWS has introduced Cost Anomaly Detection, a new feature now in beta driven by machine learning that pledges to notify admins of "unexpected or unusual spend". Bill shock is a problem suffered, on occasion, by small and big AWS customers alike. At the small end, there are cases like that of Chris Short, using AWS for his …

I do wonder how many organisations chasing cost savings by moving to the cloud will find themselves seriously reamed over the next decade. Users are very good at ramping up usage accidentally. Anyone who has seen an email storm with thousands of "remove me from the list" replies will understand that, now make that "pay per byte" and watch the CTO & CFO wince.
I feel little sympathy for them.
Cloud hosting is intrinsically less secure, since administration logins have to pass through an external, public, network (however well thought out the session initiation encryption may be) from an infrastructure that's outside of the cloud's security framework. There are often significant economies of scale to be gained, particularly for small and medium sized organizations that can't afford dedicated administration staff for tasks like patching, backup, and netflow monitoring. But paying a cloud provide for hosting administration denies the organization the economies of scale that would otherwise be gained for local administration and security, making any local security more expensive. If local security is weak, then the logins to administer cloud services are easily compromised from the client location, and the cloud security fails. This is how most cloud security failures occur. Two factor logins provide limited benefits, since a legitimate session from a compromised local machine can be hijacked.
Very large organizations that use public cloud are often wasting money and taking unnecessary risks.
Large organizations can gain most of scale benefits of cloud hardware and platform maintenance and add to that the benefit of protecting the organization with scale savings on very strong local security.
