Monolithic vs Composable vs Microservices: Choosing the Right Architecture for Your eCommerce Platform

When it comes to eCommerce, selecting the best architecture for your commerce platform is crucial to maintaining a competitive edge. Monolithic, Composable, and Microservice architectures are among the various options available.

"If your business is not on the internet, then your business will be out of business" - Bill Gates, co-founder of Microsoft.

Monolithic Architecture: A monolithic architecture is a traditional approach in which all application components are tightly integrated and deployed as a single unit. This means that any change or update requires the entire application to be re-deployed, making it difficult and slow to adapt to changes as the application grows. This approach can be a good fit for smaller eCommerce platforms with less complexity, where the overhead of maintaining a more distributed architecture may not be necessary. For example, an online bookstore with a limited product range may benefit from the simplicity and efficiency of a Monolithic architecture.

Composable Architecture: A Composable architecture is designed to be flexible and modular, allowing businesses to add or remove components as needed to create a custom eCommerce platform. This approach enables companies to create highly personalized and scalable shopping experiences for their customers by selecting and integrating only the required components. The Composable architecture approach can make it easier to adapt to changing business requirements, as the platform can evolve without having to rebuild the entire application from scratch. For example, a fashion retailer could use a Composable architecture to provide a personalized shopping experience for their customers based on their browsing history.

"Any sufficiently advanced technology is indistinguishable from magic." - Arthur C. Clarke

Microservice Architecture: In contrast, a Microservice architecture breaks down an application into smaller, independent components, each with its own business logic and APIs. This approach can provide great scalability and flexibility, as each component can be scaled and deployed independently. A Microservice architecture can also make it easier to adapt to changing business requirements, as updates can be made to individual components without having to rebuild the entire application. However, it can also add complexity and require more resources to manage, which can make it more suitable for larger eCommerce platforms with more complex requirements. For example, a large-scale retailer with multiple product lines and global operations may benefit from the scalability and flexibility offered by a Microservice architecture.

"The best way to predict the future is to invent it." - Alan Kay

Overall, it is important to evaluate the advantages and disadvantages of each architecture type and choose the one that best meets your business needs and goals for your eCommerce platform. Other types of architectures that applications use include serverless, event-driven, and hybrid approaches, among others.
