EA Practitioners in the IT Architect Role
In practice, the IT architect role is often divided by the specialty areas into the sub-roles of the application architect role, platform architect role, infrastructure architect role, utilization architect role, telecommunications architect role, and management architect role. In practice, the infrastructure architect role is often divided into the middleware architect role, platform architect role, storage architect role, network architect role, and security architect role.
When the IT architect role is divided into sub-roles, the IT architect role enables and assures these architectural roles are integrated in their efforts so their architectures integrate and with other architectures outside the IT architecture.
Similarly, the infrastructure architect role enables and assures the architect roles within infrastructure are integrated in their efforts so their architectures integrate and with other architectures of the IT architecture.
It should be noted in practice, the IT architect role is often fully or partially combined with the enterprise architect role or other architectural roles to provide an organizationally needed job (a “specialty”) to address special needs and other organizational needs and limitations of the organization.
