I don’t know how to handle this Programming question and need guidance.

Whether you are developing code, monitoring system utilization, or debugging an application, you need to consider the Pareto principle, also known as the 80/20 rule, or the rule of the vital few and the trivial many. If you consider the Pareto principle, you may find that you do not need to optimize all of an application’s code. Instead, you can focus your effort on 20% of the code that users use most often. Consider system performance monitoring. What other relationships, such as disk space use or database space use, may relate to the Pareto principle? How do these fit into the current cloud paradigm? Does this work for all cloud facets (IaaS, PaaS, etc.) or does it only work for specific cloud mediums? Why or why not?
