Explain Monolithic vs SOA vs Microservices.

Monolithic Architecture: is "like a single and big container" where all the software components of an application are bundled together (tightly coupled). It is usually built as one large system and is one code-base.

SOA (Service-Oriented Architecture): is a group of services interacting or communicating with each other. Depending on the nature of the communication, it can be simple data exchange or it could involve several services coordinating some activity.

Microservice Architecture: It involves structuring an application in the form of a cluster of small, autonomous services modeled around a business domain. The functional modules can be deployed independently, are scalable, are aimed at achieving specific business goals, and communicate with each other over standard protocols.
