Bremen-based abat AG positions itself as an advocate of modular IT systems with a specialist article on Composable Architecture. The approach breaks down monolithic enterprise software into interchangeable components – companies should thus be able to respond more quickly to market changes. Whether the term is more than just a new label for service-oriented architecture depends on the implementation: real business capabilities as modules instead of technical microservices would be the difference. For abat customers, this could mean shorter implementation cycles, provided that compatibility between the components is actually guaranteed.
