17 Plus and minus Benefits Faster and cheaper accommodation of existing systems. Increased flexibility, easier to change as requirements change. Predefined ready-for-use service types. More configuration rather than integration coding. Incremental changes can be applied with zero down-time, enterprise becomes "refactorable". Disadvantages Requires more hardware than simple point to point messaging. New skills needed to configure, manage, and operate an ESB. Extra overhead and increased latency caused by messages traversing the extra ESB layer and additional XML processing Extra team(s) involved setting up communication 17
