Increasing System Integration – Being a standardized method for communication allows multiple systems to interact with one another across the enterprise.
Increased Vendor Neutrality – the ability to use the proper technology at the appropriate time. Vendor neutrality within large organizations is important, in that it allows for the diversity that inherently exists within a corporation without limiting each part of the organization to it’s individual silo’s.
Enterprise Architecture – When you open up your application to other parts of the enterprise as a consumable service – or group of services, it makes the solution available to Enterprise Business Modeling and available as an entity that can be made part of a bigger problem solution. In other words, it gives the Enterprise Architects the ability to use individual solution architectures more as if they were components of a larger model, rather than as a self contained entities.
Reuse – As with the main driving force behind Object Oriented Programming, the ability to reuse logic is a compelling concept. If you build the same component each time you build a new system you in essence have to fund it’s construction each time.
Agility – The ability to use, then reuse – in different ways or for different requirements – system components as the business changes makes SOA extremely flexible to changing business dynamics.
