Distributed applications, devices, and services appear in many different arrangements in an enterprise. At your company, you probably access data from your intranet services, from computers distributed throughout the company network, and from services across the firewall out on the Web. For example, you might access a calendar-sharing application or a financial application to fill out expense sheets. Someone must maintain all these applications. Not only the applications, but also the hardware that supports them must be maintained. Resource management encompasses both applications and hardware. In fact, both application and hardware management can be supported through the development of Java Management Extensions (JMX) resource management software. This book will show how you can use JMX to manage and monitor all your resources across an enterprise—both software and hardware.
