A root certificate is indeed the foundational certificate issued by a Certificate Authority (CA), serving as the trusted anchor for a public key infrastructure (PKI). It is used to verify the authenticity of other certificates issued by the CA, creating a chain of trust.

The subordinate CAs provide redundancy and load balancing. The root CA is usually off-line. Here even if a subordinate CA is compromised, the root CA can revoke the subordinate CA, thus providing redundancy. Web of Trust: Here CAs form peer-to-peer relationship. This model is difficult to manage as the number of CAs grow larger. This kind of trust relationship may happen when different divisions of a company have different CAs, and need to work together. Here CAs must be configured to trust one another. Bridge CA (BCA) architecture: This architecture overcomes the complexity involved with Web of Trust model. A "bridge CA" acts as the central co-ordinate point. All other CAs (known as principals) trust the "bridge" CA.
