Answer:
c. Service oriented architecture (SOA)
Explanation:
In a service oriented architecture (SOA), a component of an application provides services to other components of the application or other applications majorly via a communications protocol over a network. In other words, SOA is a programming or software development technique in which services communicate with each other across different platforms.
One key principle of SOA is to design an application (which in itself is a piece of software with multiple features) that is independent of any product, service, vendor or technology but can be integrated into other applications. SOA makes use of loose coupling - a technique in which a client service remains independent of another service that requires it.
In contrast, a monolithic architecture aims at developing a software that is self-contained, independent and not to be integrated into other applications.
On another hand, Software as a service (SaaS), though a bit similar to SOA, is a model in which an application is made available to customers basically through a network. Users basically access the application via a browser.
Therefore, the best option is
C. Service oriented architecture.
