N-tier architecture is a good fit for small and simple applications because of its simplicity and low-cost. Also, it can be a good starting point when architectural requirements are not clear yet. [1] [2] A three-tier architecture is typically composed of a presentation tier, a logic tier, and a data tier.
N 2 chart example. [1] The N 2 chart or N 2 diagram (pronounced "en-two" or "en-squared") is a chart or diagram in the shape of a matrix, representing functional or physical interfaces between system elements. It is used to systematically identify, define, tabulate, design, and analyze functional and physical interfaces.
Tier III: full N+1 redundancy of all systems, including power supply and cooling distribution paths Tier IV : as Tier III, but with 2N+1 redundancy of all systems A Tier III system is intended to operate at Tier II resiliency even when under maintenance, and a Tier IV system is intended to operate at Tier III resiliency even when under maintenance.
Multitier programming (or tierless programming) is a programming paradigm for distributed software, which typically follows a multitier architecture, physically separating different functional aspects of the software into different tiers (e.g., the client, the server and the database in a Web application [1]).
A zone diagram is a certain geometric object which a variation on the notion of Voronoi diagram. It was introduced by Tetsuo Asano, Jiří Matoušek, and Takeshi Tokuyama in 2007. [1] Formally, it is a fixed point of a certain function. Its existence or uniqueness are not clear in advance and have been established only in specific cases.
Code diagrams (level 4): provide additional details about the design of the architectural elements that can be mapped to code. The C4 model relies at this level on existing notations such as Unified Modelling Language (UML) , Entity Relation Diagrams (ERD) or diagrams generated by Integrated Development Environments (IDE) .
The distribution layer is the smart layer in the three-layer model. Routing, filtering, and QoS policies are managed at the distribution layer. Distribution layer devices also often manage individual branch-office WAN connections.
