Just as we have gone from servers to instances, instances to containers, and containers to functions. The idea of memoryless to move low usage services to nonrunning services.
Using memoryless and containers with intelligent load balances services can be ramped up during the day and turned on to memoryless systems at night to save money.
Even though the service is simple and uses low resources it can still be scaled up to enable large environments.
With the MemoryLess system, 40 meg is all that is needed to start the service and only enough memory to run each piece of code so one instance or container can run the whole site.
