In a world where we encounter rapid evolving technology in software development, one of the most critical phases is selecting the appropriate architecture for your software. Software architecture forms the backbone of any successful application. It defines the structure, organization and different interactions of the system components usually having an ultimate impact on performance, scalability, maintainability and security. The choice of the right architecture is not just about ticking boxes but choosing a blueprint that aligns with your project's unique needs and goals.
Questions to ask yourself
Before diving into the knowing specific architectures, let me draw your mind to ask yourself these questions, from there you will have a complete clarity over your choice. Also, it is good to know that building a good architecture for your system most not be a single one, it can be a combination of 2 or more. Let's go...
- What are the core functionalities of your software?
- Who are your target users and what are their expectations?
- What are the scalability, performance and security requirements?
- What are your resources constraints?
- Do you need to integrate an existing system to your project?
What are your options?
- Monolithic Architecture: Everything is in a single unit. Here, we speak about simplicity and ease of development for small, well-defined projects. The greatest challenge can arise in scaling and maintaining complex applications.
- Microservices Architecture: Here there is a breakdown of the application into independent manageable services. This promotes agility scalability, agility, independent development and team collaboration. A major drawback is the fact that it adds complexity when it comes to orchestration and communication.
- Client-Server Architecture: In this architecture we have the client (user interface) seperated form the the data processing(Server). Scalabilty and centralized control are supported and all modifications to the server side affects all the clients.
- Layered Architecture: Here the system is handled into 4 distinct layers. This involves presentation, business logic, persistence and data access layers. Though maintainability is promoted, some issues may arise as for complexity if interlayer communication.
- Event-Driven Architecture: Here components react to events rather than direct calls, enabling loose coupling and real-time responsiveness. This excels in distributed systems, but debugging and tracing issues can be harder.
- Serverless Architecture: Here the developer is allowed to build and run applications and services without managing infrastructures. This is cost-effective and scales automatically. Some issues may lead to vendor lock-in and has limitations in terms of local development and debugging.
Some factors to consider while choosing
- The development teams
- Evaluating maintainability and future growth
- Accessing scalability and performance needs
Conclusion
The choice of an appropriate architectural design for your system is a timely process and requires a lot of factors, so necessary procedures should be taken into consideration.

What about serverless+hybrid cloud, microservices +macroservices(monoliths), client+server+events, and everything working together on an multi-layered system? There is not a single choice - sometimes you mix them.
That's a great point! You're absolutely right that in large and complex systems, a single architectural pattern rarely suffices. Mixing and matching different approaches based on specific needs is often the most effective strategy. Here's how your additional points tie into the overall discussion:
Serverless + Hybrid Cloud:
Serverless functions can be a great fit for handling specific tasks within a larger system, especially for event-driven scenarios or microservices that only need to run temporarily. Hybrid cloud deployments allow leveraging both public and private cloud resources depending on cost, security, and control requirements.
Microservices + Macroservices (Monolithes):
Not all functionalities within a system require the granular independence of microservices. It can be efficient to maintain certain tightly coupled features as a monolith (macroservice) for simpler management and data consistency. Microservices are best suited for loosely coupled functionalities with independent scaling and development needs.
Client + Server + Events:
Client-server architecture remains fundamental for user interaction and data exchange, while event-driven communication between system components enhances reactivity and scalability. The combination enables both traditional user interfaces and sophisticated real-time interaction.
Multi-layered System:
Layering your architecture helps organize functionalities and promotes maintainability. You can have presentation, business logic, data access, and event processing layers, each potentially utilizing different architectural patterns within them (e.g., serverless functions in the eventing layer, microservices in the business logic layer).
So in summary, get your own texture and combination for the right architecture which suits your use case.
