 Infrastructure-centric design is an approach that focuses on connecting devices and applications to a central infrastructure, rather than directly to each other. This method reduces the number of point-to-point connections within the architecture, streamlining communication and improving overall efficiency.
 
-By utilising an infrastructure-centric design, the $N^2$ problem can also be mitigated. The $N^2$ problem refers to the exponential increase in the number of point-to-point connections required as an architecture scales. In an architecture with $N$ devices or components, each one would need a direct connection to every other device, resulting in $N * (N-1) / 2$ total connections. This leads to a significant growth in complexity and the potential for difficulties in managing, securing, troubleshooting, and maintaining the architecture as the number of devices increases.
