What is a monolith server ?
A monolith server is a server that utilizes a monolithic architecture, as a monolithic server is self-contained and does not require any dependence on any other servers. The reason behind this kind of design follows a logical approach that the server in itself is capable and responsible for all the tasks that have to be performed and can perform every step needed to perform a function, so it doesn’t have the hectic job to not process any request due to fault of some outside server.
An architecture can be categorized as Monolithic if it consists of all the dependencies in a single program. The Monolithic Architecture comprises of the following single platform components to properly function the complete server:
- Authorization: It authorizes if the user is associated with the server or not, if the server cannot verify the user then the authorization is failed and an error is returned.
- Presentation: It handles the HTTP requests and responds with either HTML or XML/JSON(for web services APIs).
- Database layer: This layer is responsible for accessing the database with the data access objects.
- Business logic: This comprises the business model of the server architecture.
- Application integration: This is this integration with the REST APIs or integration with any other Data Sources.
- Notification module: This module carries the operation of sending email notifications whenever the required condition is met.
Applications of a Monolithic server:
- These can be used to implement simple architecture projects such as static websites.
- These can be used as a base while commencing a new project or software as we can switch to microservices at a later stage whenever required.
- These are mainly used for static design as they are easy to maintain in a single file or directory.
- They can be used when an application requires a direct data interface with the database.
Advantages of Monolithic server:
- Its very simple to work at the beginning with the Monolithic Architecture.
- We can simply implement end-to-end testing with UI testing with Selenium.
- It is easy to deploy to the server as you have to copy the packaged application to a server.
- It is simple to scale as we can run multiple copies behind a load balancer.
- Proper management of the codebase can ensure productivity for a greater time period.
Disadvantages of Monolithic server:
- If the application is too large it will be difficult to maintain the server.
- If the application is complex the changes can take time to be done correctly.
- The size can slow down the startup time of the application.
- It will be challenging while scaling if different modules have conflicting requirements.
- Monolithic servers are less reliable in terms of bugs as this can potentially bring down the entire process.
- Monolithic servers have difficulty while using advanced technologies at a later stage in development.
