Introduction about Software architectures On Back End Process

 As we move from monolithic to N-tier to microservices, we gain some things and lose others. Will discuss theoritically about those topics

Let's explore three important architecture styles today: monolith, N-tier, and microservices -

1. 𝗠𝗼𝗻𝗼𝗹𝗶𝘁𝗵:
   - 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: A monolithic architecture is a single-tiered software application where all the components (user interface, server-side application, database) are combined into a single codebase.
   - 𝗔𝗱𝘃𝗮𝗻𝘁𝗮𝗴𝗲𝘀: Simplicity, easy to develop, test, and deploy. Suitable for small-scale applications with fewer features and components.
   - 𝗗𝗶𝘀𝗮𝗱𝘃𝗮𝗻𝘁𝗮𝗴𝗲𝘀: Difficult to scale, slow release cycles, risk of complete system failure due to a single component failure, tight coupling of components makes it harder to make changes without affecting other parts.

2. 𝗡-𝘁𝗶𝗲𝗿:
   - 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: An N-tier architecture divides an application into several layers (or tiers) that handle specific responsibilities, such as presentation (UI), business logic (application layer), and data storage (database layer). Each tier can run on a separate server.
   - 𝗔𝗱𝘃𝗮𝗻𝘁𝗮𝗴𝗲𝘀: Better separation of concerns, easier to scale and maintain individual layers, provides flexibility in technology choices for each layer.
   - 𝗗𝗶𝘀𝗮𝗱𝘃𝗮𝗻𝘁𝗮𝗴𝗲𝘀: More complex than monoliths, requires good coordination between tiers, may lead to performance bottlenecks if not designed properly.

3. 𝗠𝗶𝗰𝗿𝗼𝘀𝗲𝗿𝘃𝗶𝗰𝗲𝘀:
   - 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: A microservices architecture divides an application into small, loosely coupled services, each responsible for a specific business capability. These services can be developed, deployed, and scaled independently.
   - 𝗔𝗱𝘃𝗮𝗻𝘁𝗮𝗴𝗲𝘀: Scalability, flexibility, easier to maintain and update specific services, enables faster release cycles, can use different technologies for different services.
   - 𝗗𝗶𝘀𝗮𝗱𝘃𝗮𝗻𝘁𝗮𝗴𝗲𝘀: Complexity in managing multiple services, network latency, requires robust service orchestration and monitoring, potential for data inconsistency due to distributed data storage.

The choice of architecture depends on various factors such as the size and complexity of the application, team size, technology stack, and scaling requirements.

Monoliths are easier to develop but harder to scale, while microservices offer scalability and flexibility but come with increased complexity.

N-tier architecture has a long-standing history in the world of software development, and it was highly popular before the rise of microservices.

N-tier architecture sits in between, providing better separation of concerns and scalability compared to monoliths while being less complex than microservices.
