Service-Oriented Architecture (SOA), also known as, Service-Based Architecture (SBA), is a distributed architecture pattern in which an application is organized into a collection of loosely coupled, reusable services. Each service is a self-contained unit that performs a specific task or function, and communicates with other services using standard communication protocols, such as REST, SOAP, or gRPC.

A pipeline architecture is a monolithic architecture style, which means a single deployment unit for all of the code. The essential characteristic of pipeline architecture is that data or tasks are processed in a series of stages. Each stage receives the output from the previous stage, processes it, and passes it on to the next stage.

Layered Architecture is a monolithic architecture style, which means a single deployment unit for all the code. This style is also known as the n-tiered architecture.

Software architecture is very context-dependent. Factors such as the software application’s goals, the development team’s size and budget, and business needs play a significant role in the choice of software architecture.
