The document discusses deploying a service-oriented architecture (SOA) to support internal integration of migrants in Germany. It notes the complex federal system with different authorities at federal, state, and local levels handling migration. The SOA aims to connect the different technical systems used by authorities like the Federal Office for Migration and Refugees, foreigner authorities, and integration course providers. The experiences discussed include starting small but planning comprehensively, prioritizing security, and reusing services across processes.
