The IT world is changing rapidly, which is why system integration is becoming increasingly important. IT infrastructures are developing more and more from monolithic, homogeneous structures into a heterogeneous, agile mix of stationary backend systems, distributed systems and cloud solutions with fat clients, browser-based and mobile frontends. New, innovative applications will have to interact with existing core systems, exchange data and support end-to-end processes. In short: they have to be integrated into a harmonious whole. abilex uses innovative ESB technologies to design sustainable integration environments.
