Monolithic architecture remains a popular topic in software development because it is a simple and straightforward approach to building applications. In a monolithic architecture, all the components of an application are combined into a single, tightly-coupled codebase, making it easier to develop, test, and deploy the application. This simplicity also makes it easier to understand the flow of data and control in the system, and can lead to faster development times for smaller applications.
However, as applications grow in size and complexity, the monolithic architecture can become difficult to maintain and scale. The tightly-coupled nature of the codebase makes it difficult to update individual components without affecting the entire system, and can lead to increased downtime during deployments.
Despite these challenges, many organizations continue to use monolithic architecture, particularly for small to medium-sized applications, due to its simplicity and ease of development. Additionally, the recent trend towards microservices has led to an increase in interest in monolithic architecture as a contrast and comparison point.
