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.
Monolithic Architecture:
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.
