Modular Monolithic Architecture
Modular monolithic architecture divided our application logic into modules and each module will be independent and isolated and should have its own business logic, database schema.
Each module can follow their own logical separations, layered architecture style or clean architecture.
The Modular Monolith architecture breaks up the code into independent modules, each module encapsulates their own features.
Modules are represents Bounded Context of our application domain and we group features of Domain contexts in modules.
Reduces the dependencies of a module and we can develop or modify a module without it effecting other modules.

Benefits of Modular Monolithic Architecture
Encapsulate Business Logic
Business logics are encapsulated in Modules and it enables high reusability, while data remains consistent and communication patterns simple
Reusable Codes, Easy to Refactor
For large development teams, developing modular components of an application will increase reusability. Modular components can be reused that can help teams establish a single source of truth.
Better-Organized Dependencies
With modular monoliths architecture, application dependencies will be more organized and visible. This will help developers to easily assess which parts of the application require which dependencies.
Less-Complex than Microservices Architecture
Easier to manage a modular monolith rather than hundreds of microservices, because Modular Monolithic comes with basic underlying infrastructure and operational costs low.
Better for teams
Easier for developers to work on different parts of the code. with Modular Monolithic architecture, we can divide our developer teams effectively and implement business requirements with minimum affect to each other
Challenges of Modular Monolithic Architecture
Can’t diversifying technology
Modular monoliths don’t provide all benefits of microservices. If you need to diversifying technology and language choices, you can’t do it with Modular Monolithic Architecture. These types of polyglot technology stacks can’t use with Modular Monolithic Architecture.
Can’t Scale and Deploy Independently
Since the application is a single unit, it can’t be scale separated parts or deploy independently like microservices. And this kind of applications has to move microservices due to reaching out scalability limits and also performance issues.
