Main Software Architectures

The three main types of software architectures commonly encountered are monolithic, layered, and microservices architectures.

Monolithic architecture refers to software built as a single, unified structure that incorporates all functionality into one application. While this may seem outdated, it has certain benefits.

Its limited ability to scale and adapt is balanced by ease of deployment and straightforward development due to reduced complexity.

Layered architecture, on the other hand, breaks a monolithic structure into groups of related functions and calls. Different concerns and responsibilities are separated into layers.

This approach is well suited for enterprise applications and enables independent development and maintenance between layers. However, it is still deployed as a single unit and introduces additional performance overhead due to the added layers.

Microservices architecture differs the most by adopting a fully independent services model, where each service is dedicated to a specific function.

This separation enables greater scalability and flexibility but comes at the cost of increased system complexity and operational overhead.
