Enabling scalability, availability, and resiliency with Azure and .NET 5

A short search on scalability returns a definition such as the ability of a system to keep working well when there is an increase in demand. Once developers read this, many of them incorrectly conclude that scalability only means adding more hardware to keep things working without stopping the app.

Scalability relies on technologies involving hardware solutions. However, as a software architect, you must be aware that good software will keep scalability in a sustainable model, which means that a well-architected software can save a lot of money. Hence, it is not just a matter of hardware but also a matter of overall software design. The point here is that the running cost of a system should also be a factor in the architectural decisions.

In Chapter 1, Understanding the Importance of Software Architecture, while discussing software performance, we proposed some good tips to overcome bad performance issues...
