CIOs and IT experts are facing ever increasing new requirements from the business experts forextending their services to be available everywhere around the world. Under cost pressure theyneed to consolidate data centers and business applications plus they need to pay attention tonew compliance rules and security regulations. IT has to support the extended enterprise (Fig 1)which does not end any more at the doorstep of the data center or any organizational boundariesof an enterprise any more. Company employees, business partners and customers are all end-users of IT and demand secure and low response time access to business applications fromwherever they are. In addition, web-service style message traffic in between application compo-nents is very much on the rise due to the need to facilitate inter- and intra company businessapplication integration. The network becomes the increasingly important glue in between moreand more globally distributed and used business application components and end-users.SAP addresses modern business needs through enterprise service-oriented architecture (enter-prise SOA) architected solutions. Naturally these solutions run on-top of the Network which com-prises out of the internal data center local area networks (LAN) as well as intra company andInternet Wide Area Network (WAN) connections. To no small extent the performance of the net-work can impact the performance of an overall application+network IT landscape. When allowingaccess to SAP® business applications over Wide Area Networks security requirements are usu-ally high. However, adding secure communication features often reduce network and applicationperformance as well.In the end the business requirement for global use of SAP business application adds new re-quirements to a global IT infrastructure compared to traditional 1990's ERP solutions which weredeployed and used mostly within the same local location.This leads to the question on how to test global enterprise SOA deployments. Functional andconventional stress testing of application components in a LAN environment is still needed inorder to prepare new application deployments for productive use. However, some testing shouldbe added to ensure proper optimization of communication across Wide Area Networks as well aswith the added overhead of security features.Within the Enterprise Services Community program, some network equipment vendors, a test toolvendor and SAP came together to perform ...
