A multitiered architecture project is a type of project that involves designing and implementing a system that consists of multiple layers or tiers, such as presentation, application, and dat a. A multitiered architecture project can provide a high level of redundancy, scalability, and performance, as each tier can have multiple servers or components that can handle requests and failures independently. A Tier 5 redundancy level is the highest level of redundancy that requires a fully redundant, mirrored system plus one additional backup unit for every component12.
