Do you also think that Micro-service architecture is always better than Monolithic architecture?
Let’s first understand the key difference between the two. A monolithic application is built as a single, unified unit, while a micro-services architecture is a collection of smaller, independently deployable services. In a monolithic architecture, all the functions are managed and served in one place, while in a micro-services architecture, each service has its own business logic and database with a specific goal.
Both of these architectures have their own advantages and disadvantages. The choice between Micro-service and monolithic architecture depends on factors such as the size and complexity of the application, the development team’s expertise, and the specific requirements of the project.
Advantages of Micro-service Architecture
- Scalability: Improved scalability, as each service can be independently scaled
- Improved fault isolation: Problems in one Micro-service are less likely to affect the entire system
- Flexibility: Each Micro-service can be developed, deployed, and scaled independently, allowing for greater flexibility
Advantages of Monolithic Architecture
- Easier and faster development: Simpler to develop and deploy, especially for smaller projects
- Simplified deployment: Deployment is easier as the entire application is contained in one executable file or directory
- Less latency: Have lower latency as all calls are local
Disadvantages of Micro-service Architecture
- Increased maintenance costs: Managing a larger number of services can lead to increased maintenance costs
- Organizational complexity and overhead: Coordinating and managing multiple services can introduce organizational complexity
- Decreased performance: Consumes more memory, clock-cycles, and network bandwidth than a comparable monolithic architecture
Disadvantages of Monolithic Architecture
- Lack of flexibility: Tightly coupled to the technologies used inside the monolith, limiting flexibility
- Decreased scalability: Each component cannot be scaled independently
- Increased risk of failure cascades: A bug in one module can bring down the entire monolithic application
