Just like Web services add complexity to the task of management, it also brings to the table a set of technologies that may simplify the task of management itself. By realizing a set of technologies for Web service description, discovery and invocation it has provided management community the capability to virtualize a wide array of network, system, application components. This has led to the application of Web services technology to the domain of grid computing and utility computing. Both these domains appear quite promising for the vision of Web services being used in management. [ABSTRACT FROM AUTHOR]

In order to realize the vision of Web services enabling inter-enterprise integration it is important to not only standardize on set of technologies but also to ensure that these interactions can be monitored and managed. In this chapter we looked at the requirements and the technologies that are available to enable and manage Web service to Web service interactions. We also discussed some standards that are important to enable web service to web service interactions like WS-Security, WS-Reliability and SLA standards and efforts. [ABSTRACT FROM AUTHOR]

While instrumenting Web services, it is useful to identify the important business transactions that have to be measured. It is also important to identify which transactions are created in the context of another transaction. This is important to identify parent-child relationships between transactions. The parent child relationship identification is necessary to trace the end-to-end flow of transactions through distributed client/systems. It is also important to keep in mind the target audience for the instrumentation data and the corresponding performance degradation that excessive instrumentation may result into. Certain standards like ARM, SNMP, and JMX exist for instrumentation/manageability of applications. The instrumentation data so obtained may be aggregated and used for calculating higher-level metrics. These higher-level metrics may form the basis of Service-Level Agreements (SLA) and may populate the business-level views exposed to business managers. [ABSTRACT FROM AUTHOR]

This chapter introduced the basic notions of application and infrastructure management for Web services. Metrics have been presented that can be used for build monitoring models for applications or infrastructure components. Monitoring models provide a systematic foundation for monitoring and archiving data that characterize the behavior and the boundaries of "normal" behavior for a Web service. Monitoring, or more general, management models are also the precursory for tool support and implementing an effective management solution for a Web service. Enterprise management will evolve from infrastructure management to service management. Services will turn management itself into a service, which is needed to operate (managed) services. Services encapsulating and abstracting diversity found in infrastructure is another step towards managing business in conjunction with supporting IT systems. Business-aware management capabilities can be seen today in management products. [ABSTRACT FROM AUTHOR]

The evolution of enterprise computing has had a dramatic impact on the role of system management, with system management and administration proving to be a difficult issue for most organizations. With the demand for IT organizations to provide more information faster and with greater reliability and accuracy, IT organizations are seeking for solutions that help them manage the integrated enterprise. Enterprise management systems enables administrators to perform resource, system, and network management, proactively manage systems and processes, automate tasks, and add, remove, or modify functionality based on business needs. The technologies that have been developed in the context of enterprise management are quite useful in the domain of web services. Especially CIM, ITSM, eTOM, PARLAY have capabilities that can be directly and indirectly leveraged in undertaking model-based management of web services. [ABSTRACT FROM AUTHOR]

Every change in the business environment impacts the IT infrastructure. IT infrastructure and management systems must accommodate change in business needs at lower cost. Management products that have traditionally been focused on network and systems management have begun to transition into higher management layers of application management. The chapter discussed the application life-cycle management and the processes involved in it. It also discussed some of the existing relevant management standards, namely SNMP, CMIP, CORBA, which are discussed later in more detail. Some of these are discussed more details in the following chapters. [ABSTRACT FROM AUTHOR]

Web services are emerging as the de-facto mechanism of making services available on the web. In order to enable this scenario a set of standards are being worked upon. These standards range from those related to describing the service (WSDL), discovering the service (UDDI, WS-IL) to business processes that drive the message exchange (WSFL, XLANG, BPEL4WS, ebXML). In order to manage Web services it is thus important not only to understand how these different technologies fit together but also the effect that they have on the current enterprise stack.
