A system architecture based on a logical hub concept enables companies to avoid the handicaps of rigid hub-and-spoke solutions without giving up its advantages.

• A number of independent integration adapters are organized within a logical center. As a whole, these act like a logical enterpriseservice bus (ESB).
• Unlike an ESB the individual integration adapters can be distributed across a wide variety of environments; on-premise, (multi-) cloud or even software-as-a-service (SaaS) solutions.
• In principle, the implementation is technology agnostic. In practice, it is usually based on a defined set of different open-source technologies - avoiding vendor lock-in and improving manageability.
• Architecturally, this setup can be changed at any time, in stages as needed, and adapted to incorporate future technological developments.

Integration architecture using a logical hub paradigm delivers a highdegree of flexibility.
