Systems Performance: Enterprise and the Cloud 1st Edition 48320

 

Large-scale enterprise cloud, and virtualized computing systems have introduced serious performance challenges. Now, internationally renowned performance expert Brendan Gregg has brought together proven methodologies, tools, and metrics for analyzing and tuning even the most complex environments. Performance Systems: Enterprise and the Cloud focuses on Linux® and Unix® performance, while illuminating performance issues that are relevant to all operating systems. You'll gain deep insight into how systems work and perform, and learn methodologies for analyzing and improving system and application performance. Gregg presents examples from bare metal systems and virtualized cloud tenants running Linux-based Ubuntu®, Fedora®, CentOS, and the illumos-based Joyent® SmartOS™ and OmniTI OmniOS®. He systematically covers modern performance systems, including the "traditional" analysis of CPUs, memory, disks, and networks and new areas including cloud computing and dynamic tracing. This book also helps you identify and fix the "unknown unknowns" of complex performance: bottlenecks that emerge from elements and interactions you were not aware of. The text concludes with a detailed case study, showing how a real cloud customer issue was analyzed from start to finish.

 

 This guide is indispensable for anyone who operates or enterprise cloud environments: system, network, database, and web admins; developers; and other professionals. For students and others to new optimization, it also provides exercises reflecting Gregg's extensive instructional experience.
