As eCommerce businesses evolve, so too must the architecture behind them. A key decision for tech leaders today is choosing between monolithic and microservices architecture. Both approaches have strengths and trade-offs, but their impact on scalability, speed to market, and operational flexibility can’t be overstated. This post explores the core differences between monolithic and microservices architecture in the context of eCommerce, helping you make a more informed decision for your tech stack.
In a monolithic system, all components, frontend, backend, business logic, and database access, are combined into a single, tightly coupled application.
Unified codebase and deployment pipeline
Tight interdependencies between modules
Any change requires redeploying the entire application
Monoliths can be ideal for startups or smaller teams launching an MVP quickly. However, they tend to become rigid and harder to scale as the business grows.
Microservices architecture splits functionality into independent, loosely coupled services. Each service manages its own logic, database, and scaling.
Each service is autonomous
Services communicate via APIs
Teams can work and deploy independently
Microservices offer flexibility and agility but introduce complexity in communication, monitoring, and deployment.
Examples: Magento, WooCommerce, Oracle ATG
All-in-one solutions: product catalog, cart, checkout, CMS
Easier to manage initially, but limited agility
Slower go-to-market for new features
Difficult to scale individual capabilities (e.g., search or promotions)
Examples: commercetools, Shopify Hydrogen, BigCommerce with APIs
Composable approach: separate engines for checkout, CMS, PIM, etc.
Faster innovation, better performance optimization
Teams can iterate independently on features like search, recommendations, or payments
| Feature | Monolithic Architecture | Microservices Architecture |
|---|---|---|
| Deployment | All-in-one | Service-specific |
| Flexibility | Low | High |
| Scalability | Entire app | Per service |
| Codebase | Unified | Decentralized |
| Go-to-Market Speed | Slower | Faster |
| Maintenance | Complex over time | Complex from start |
| Ideal for | Small/medium projects | Mid/large-scale businesses |
You’re building a prototype or MVP
Your team is small and co-located
You need to launch fast without operational complexity
Your business has multiple customer touchpoints
You want to scale parts of your app independently
Your teams are large or distributed
You require high availability and performance
Whether your eCommerce backend is monolithic or microservices-based, Laioutr helps modernise the frontend layer:
Integrate easily with APIs from headless services or monolith APIs
Build high-performance, accessible UIs with prebuilt components
Visualize and manage the storefront
without deploying backend code
For teams transitioning from a monolith to microservices, Laioutr offers a powerful way to bridge the frontend without waiting on backend changes.
The decision between monolithic and microservices architecture depends on your business needs, team size, and long-term goals. While monoliths can be fast to start, they often become bottlenecks. Microservices offer greater flexibility and scalability — ideal for modern eCommerce brands.
With a composable frontend management platform like Laioutr, you can harness the power of either architecture and ensure your storefront evolves at the speed of your business.
