In the past year, SAP's NetWeaver has gained new abilities and has been expanded to prepare for the very competitive service-oriented architecture (SOA) market. Ziv Carth, VP of developer programs at SAP, has stated that the company is basing NetWeaver around a set of abilities called Enterprise Service architecture (ESA). SAP intends to provide an integrated stack of components that will in time permit composition of components on top of existing applications In practical terms, NetWeaver is a composition stack that allows a developer to connect to a MySAP business suite or any other rival application, assuming service-enablement, and to compose applications atop it. Jason Bloomberg, senior analyst at ZapThink, says SAP appears to have a handle on the purpose of SOA, but the company has a long road ahead in implementation of its vision. SAP, says Bloomberg, is doing more than moving into the of the Web services space. SAP is actually trying to build a whole platform for Web services, and is trying to sell the shovels and the gold at the same time. SAP wants to make sure that companies use the SAP platform, but real success is in the enterprise services architecture, which is the service atop NetWeaver. The minus side is that it is not ready, and much technology still has to be created.
