In the world of software architecture, there's no one-size-fits-all. Different architectural types offer unique advantages depending on the needs of your system. The most common types include Monolithic, Microservices, and Serverless. Each has its own structure, benefits, challenges, and use cases. Choosing the right architecture can make or break your project.

Monolithic Architecture

All functionalities are built into a single application. It's easy to develop and deploy in small projects but can become difficult to maintain and scale as the codebase grows.

• Pros: simple to develop, test, and deploy initially;

• Cons: hard to scale or update parts independently. A single bug might impact the whole system;

• Use Case: small businesses or startups with limited complexity.

Micro services Architecture

Functionality is split across independent services. Each service focuses on a single feature or module, communicating through APIs.

• Pros: high scalability, independent deployment, fault isolation;

• Cons: more complex to manage and test, requires DevOps maturity;

• Use Case: large-scale applications (e.g., e-commerce, streaming platforms).

Server less Architecture

You write functions that run in the cloud, and the cloud provider handles the infrastructure. It's event-driven and highly scalable.

• Pros: no infrastructure management, pay-as-you-use, auto-scaling;

• Cons: cold starts, limited execution time, vendor lock-in;

• Use Case: lightweight APIs, background processing, IoT events.

Understanding the strengths and trade-offs of each type will help you choose the right model for your project's scale and complexity.
