I can guess that timers in web servers can be used to specify expired connections and close them when they are expired but I can't totally understand why minimum timers are important in an event driven (asynchroneous) web server other than that? How timers and events associated in the cycle of the processing of the events which is for example shown in the image below?
Lease-to-own eliminates the expenditure of hardware replacement and allows you to pay off the server over time. Usually, this is much cheaper than leasing servers. Think of lease-to-own as credit without interest.
What do responsible coders do? They don't take detrimental shortcuts. They do take reasonable security precautions, create important automation, implement sufficient logging, fix things they break, and care about users.
