# Subnets

Subnets constitute a vital network resource within the Skynet protocol, linking interconnected Clusters and enabling peer-to-peer communication. These subnets are pivotal in optimizing protocol computation by efficiently allocating resources and ensuring cluster-level fault tolerance.&#x20;

Enterprises leverage subnets to deploy applications on the protocol, allowing for seamless scalability when needed, as each subnet can accommodate sets of applications and their associated resources. These infrastructural units facilitate the seamless transfer of application loads between GPU and Compute clusters, mitigating outages and optimizing resource utilization.
