It's no longer enough to manage the elements of a network in isolation: you need to manage network applications holistically, ensuring that all infrastructure and software components work together to deliver optimal performance and availability. Now, there's a network troubleshooting guide designed to help you do just that: Managing Distributed Applications: Troubleshooting in a Heterogeneous Environment. In this book, Michael Hicks presents practical techniques for troubleshooting network communications and mainframe connectivity, file/print and directory services, security and authentication, Web and e-Commerce systems, messaging systems, and more. Understand the dependencies that affect distributed and client/server application performance, and discover faster ways to troubleshoot problems in complex, heterogeneous networks. The book presents detailed graphical flowchart templates and case studies for tracking down connectivity issues, application slowdowns, intermittent performance degradation, and more. For every IT administrator, manager, and developer responsible for network reliability, availability, or performance.
