3.1.1 Fixed Scaling
In the fixed scaling mode in a two-tier web application (with n-web servers and a database server), we add additional web servers to the environment as user load increases. For the scaling model, assume that the database is infinitely scalable to support the increase in web servers. Scaling the database server is a separate exercise and is addressed outside of automated scaling.
