1. HOST BASED ARCHITECTURE
2. CLIENT-BASED ARCHITECTURE
3. CLIENT-SERVER ARCHITECTURE
4. CLOUD ARCHITECTURE

HOST BASED ARCHITECTURE
* The early types of data communications networks used host-based architecture. The host was usually a mainframe which performed the functions of data storage, data access, application logic, and presentation logic. In this architecture, the client was usually a terminal. A major problem with this architecture is that the host is required to do all the processing and as the number of applications grows on a given network, processing will slow-down significantly. The only solution will be to ...view middle of the document...

* Cloud computing architecture refers to the components and subcomponents required for cloud computing. These components typically consist of a front end platform (fat client, thin client, mobile device), back end platforms (servers, storage), a cloud based delivery, and a network (Internet, Intranet, Intercloud). Combined, these components make up cloud computing architecture.

Terminologies
