Microservices
Microservices are a software architecture where an application consists of small, independently deployable services. Each service fulfills exactly one business function and communicates with others via APIs. Unlike a monolith, each microservice can be separately developed, scaled, and updated — without endangering the overall system.
Why does this matter?
Microservices prevent the dreaded "Big Ball of Mud": when your ERP module needs an update, the entire software does not need to go offline. For growing mid-sized businesses, this means: individual business areas (ordering, warehouse management, customer portal) can evolve independently — faster innovation with lower risk.
How IJONIS uses this
We develop microservices with Node.js, Python, and Go — depending on service requirements. Communication runs via REST APIs or event-based with message queues. For mid-sized businesses, we take a pragmatic approach: not every project needs microservices — often a modular monolith is the better starting point.
