What is a Monolith?

A monolithic software architecture amalgamates all application constituents into a singular unit, yielding an efficient and scalable design. This architecture enables component communication via an API and is commonly employed for more extensive and intricate applications. Developers benefit from the streamlined development process, as all components reside within a unified codebase.

Furthermore, maintenance simplicity arises from the consolidation of all components in one location. However, potential limitations in scalability may render codebase management arduous as the application expands. Additionally, as application components grow in complexity, codebase maintenance may prove increasingly challenging.

Drawbacks of Monolith

A predominant shortcoming of monolithic architectures lies in their scalability challenges. As the application burgeons, codebase management becomes increasingly onerous. Furthermore, the maintenance of the codebase grows in complexity as application components evolve.

Monoliths also tend to exhibit inefficiency and sluggishness. Codebase clutter, a consequence of application growth, complicates issue localization and debugging. Additionally, the increasing complexity of components may render the application less responsive.

Lastly, monolithic architectures pose deployment difficulties. Given that all components are encompassed within a single codebase, application deployment demands substantial time and effort. Moreover, managing distinct versions of the application becomes problematic due to the consolidated codebase.

Splitting vs. Sticking Together

In the context of a monolithic architecture, two primary alternatives present themselves: fragmentation or preservation of unity. Fragmentation entails decomposing the application into smaller, more manageable constituents, resulting in enhanced scalability, efficiency, and deployment ease. Conversely, preservation of unity maintains the application within a singular codebase, which, while advantageous for smaller applications, may prove challenging for larger ones.

When deliberating between fragmentation or preservation of unity, the size and complexity of the application must be taken into account. For smaller applications, preserving unity may be preferable, given its less time-consuming nature and easier manageability. Conversely, for larger applications, monolithic fragmentation often proves more advantageous, rendering the application more efficient and scalable.

How to Split a Monolith

To split a monolith, follow these steps. First, analyze the codebase and identify the components that are most complex or difficult to manage. This will help you determine which components need to be split. Next, create separate codebases for each component to ensure proper management and independent deployment. Additionally, develop an API to facilitate communication between the components. Test the application to identify and fix any issues that may arise, and document the codebase to aid future developers in managing the application.

Best Practices for Splitting Monoliths

Upon opting for monolithic fragmentation, adherence to several best practices is recommended. Firstly, thorough documentation of each component is essential, facilitating developer management of the codebase and application maintenance. Secondly, devising a well-documented and user-friendly API is crucial, guaranteeing seamless communication between components.

Furthermore, implementing automated tests is vital, ensuring the application’s proper functionality. Performance monitoring of the application is also critical, enabling prompt identification and resolution of potential issues. Lastly, establishing a change tracking system is imperative, streamlining codebase management for future developers.


In summation, monolithic architectures can serve as a viable choice for larger applications. Nonetheless, they may present scalability challenges and inefficiencies. Under such circumstances, monolith fragmentation may be a more suitable approach. This entails decomposing the application into smaller, manageable components and devising an API to foster inter-component communication. Moreover, adhering to best practices, including codebase documentation, automated testing, and performance monitoring, is crucial.
