Composable Architecture

Composable Architecture is an architectural approach where digital systems are assembled from interchangeable, best-of-breed components — instead of relying on a monolithic all-in-one platform. Each component (CMS, commerce, search, personalization) is independently selected and connected via APIs. The result is maximum flexibility and future-proofing.

Why does this matter?

Composable Architecture frees businesses from vendor lock-in: when your CMS no longer fits, you replace only the CMS — not the entire platform. For mid-sized businesses, this means: gradual modernization instead of expensive complete migration, and the freedom to choose the best solution for each need rather than settling for compromises.

How IJONIS uses this

We build Composable Architectures with Next.js as the frontend framework, combined with specialized services: Sanity or Contentful for content, Algolia or Meilisearch for search, Stripe for payments, and Vercel for hosting. Each component is integrated through type-safe APIs and can be independently replaced.

Frequently Asked Questions

What is the difference between Composable Architecture and microservices?
Microservices describe how a single application is internally structured. Composable Architecture describes how the entire digital infrastructure is assembled from specialized third-party services. Microservices can be a building block within a Composable Architecture — but not every Composable Architecture uses microservices.
Is Composable Architecture too complex for mid-sized businesses?
Not when implemented pragmatically. You do not start with 20 services but with 3-4 core components: CMS + frontend framework + hosting + one specialized service (search, payments). The architecture grows organically with your requirements. The entry point is often simpler than a WordPress migration.
