What are the performance implications of Web Services Management?
This completely depends on the Web Services Management vendor and the architecture of the complete solution. The functions of Web Services Management; security, monitoring, enforcement, enablement, all need to be done somewhere in an SOA. A well-architected solution will externalize these functions from the applications to ensure consistent application of policy. The Service Manager is an extremely high performance solution. In monitor mode, the Management Point operates at zero-latency (any added latency is not measurable). In intermediary mode where is it enforcing management and security policy it has been tested under heavy load and demonstrated sub millisecond latencies. To put this into perspective, most Web services themselves will operate with 100-200 millisecond response times, some taking several seconds to respond. In this environment, the Web Services Management fabric is increasing latency by less than 1/10th of a percent. Furthermore, a well-architected Web Services Manag
