SOA Governance and API Management : Getting Started with CentraSite : Implementation Concepts : Managing Virtualized Services : Which Services Should You Virtualize?
Which Services Should You Virtualize?
 
Virtualizing Business Services at the Point of Consumption
Virtualizing Shared Services
Virtualizing Services that are in Different Domains of Control (for example, Cloud Computing)
Although it is possible to virtualize any native service that is registered in CentraSite, you will generally virtualize only certain types of services. The use of virtual services creates an additional hop in the execution path and also consumes resources from an execution perspective. It is generally not practical (or beneficial) to virtualize every native service in your environment. With respect to virtualization, you want to strike a balance between the need to provide an SOA infrastructure that is flexible and extensible with the need to maintain a manageable infrastructure that is not overly complex.
Broadly speaking, there are three types of services you should consider virtualizing:
*Business services (which you virtualize at the point of consumption)
*Shared services
*Services that are provided and consumed in different domains of control (e.g., cloud computing)
