3.1.2 Scale Everything
In the two-tier web application, rather than considering the database as an infinite resource, the database is more closely sized to the number of web servers within the initial deployment architecture. The entire environment is then scaled whenever a scale out event occurs. This maintains database resource alignment with the web server resources that are placing load on the database. The scale-everything model replicates the entire application service.
