> Especially scaling by it's nature requires knowing what approach is the best based on the employed algorithms themselves I have yet to design a system that requires more knowledge in algorithms than understanding architecture and CAP theorem. Scaling systems is based on a series of trade offs. There are very few scenarios that would require knowledge based on the underlying embedded algorithm unless your problem domain requires so.
