When designing a system, it's important to consider the limitations of the technologies chosen. Making some approximate calculations when the system is designed helps us decide on the tradeoffs of the different approaches. These approximations include: This article has a table with latency comparison numbers, common numbers used in system design calculations, and some challenges to put all of this info into practice.

Non-functional requirements refer to quality attributes or system characteristics that describe how well a software system or solution performs or behaves. This article covers well-known non-functional requirements such as reliability, availability, scalability, performance, and durability.
