The 2-tier ( web + database) and 3-tier ( web + app + database) architecture are most prevalent today. There is however an emerging architecture that is gaining traction. This I am coining this the "Latency-tier architecture". In this architecture, a cache sits in between the customer facing front-end web components and multiple internal back-end web components.

is this really anything new ... going with more of a services architecture is not new, and caching at different areas within the architecture is best. I don't think one single layer of caching, is optimal. For example you may want to cache static content for web tier, but also cache certain queries, resultsets at persistence tier.
