As a bonus, operations staff never needs to update operating systems or hardware, because AWS manages servers with no stoppage of application functionality. AWS continues to improve how it handles latency issues. One factor that dissuades many from using Lambda is the need to restart containers.

STM generates traffic that replicates the typical path or behavior of a user on a network to measure performance for example, response times, availability, packet loss, latency, jitter, and other variables). One use case for STM is to model the behavior of a customer in the form of a flow of transactions along the buyer’s journey.

Marvin Theimer, Amazon Distinguished Engineer, once jokingly said that the evolution of Amazon S3 could best be described as starting off as a single engine Cessna plane, but over time the plane was upgraded to a 737, then a group of 747s, all the way to the large fleet of Airbus 380s that it is now.
