Keeping in line with the animal theme, Eric Johnson wrote a blog post for RackSpace which introduced insects. This term was introduced to describe serverless and Functions as a Service.
Insects have a much lower life expectancy than chickens; in fact, some insects only have a lifespan of a few hours. This fits in with serverless and Functions as a Service as these have a lifespan of seconds.
Later in this chapter, we will be looking at public cloud services from AWS and Microsoft Azure which are billed in milliseconds, rather than hours or minutes.
