In the world of software engineering, the debate between breaking things down into smaller services (microservices) or keeping them unified in a single, solid block (monolith) is real.

Which approach wins the race? Let's take a look!

First of all, let me explain what Microservices and Monoliths are:

Microservices: Small, independent services that communicate with each other, offering flexibility and scalability.

Monoliths: A single, unified codebase that handles all tasks, often simpler but harder to scale and maintain.

Microservices Pros:

• Scalability and Flexibility: You can easily add new services and quickly adapt to evolving changes.
• Clear Responsibilities in the Team: Encourages delegated responsibility and clear ownership, making it obvious who does what and where the lines of responsibility lie.
• Fits the Reality: Business needs change constantly—microservices adapt better to these changes.
• Easier Maintenance: You can modify, fix, or remove a service without breaking anything else.
• Smaller Features Are Easier to Fix:

+ My personal opinion: Developers rarely read each other’s code, so smaller modules help (this is my unpopular opinion).

Microservices Cons:

• Increased Complexity: Managing multiple services requires a more complex architecture, including inter-service communication, dependency handling, and data consistency.
• Deployment Complexity: Deploying microservices involves orchestrating multiple builds, configurations, and monitoring tools, which can complicate CI/CD pipelines.
• Operational Overhead: Running a microservices architecture increases operational tasks like monitoring, logging, and maintaining infrastructure for numerous services. This often requires more sophisticated tools and additional resources.
