Book Description
QoS (Quality of Service) and Network Management are old topics. However, the fusion of IP style multimedia and wireless networks (3G) means that network managers who might previously have dealt with one or the other, must now manage and provide service guarantees for the both. This is where Managing Service Level Quality across Wireless and Fixed Networks steps in. It begins by examining the mechanisms that already existed in fixed IP data networks prior to the introduction of probe and agent technology. A look at these later developments is then supplemented with a real-world scenario of how real time application performance monitoring can not only provide service level management but can also aid in root cause analysis. This same model is then applied to a wireless environment examining which elements are required to be able to deliver multimedia services across 2nd and 3rd generation mobile networks, detailing the components of data networking that will assist in guaranteeing service level performance and the constraints placed on those guarantees when passing services over an air interface to a wireless-enabled device. It asks a simple question: will multimedia applications and the guaranteed levels of service required by them work when traversing from fixed to wireless networks? It tracks QoS components and mechanisms of both environments and looks at what will provide the glue in this brave new converged world and also provides empirical data to back up the conclusions drawn. First book available which applies QoS techniques and technologies to wireless/mobile networks 3G/UMTS Deals with the search for the real time information that constitutes the "customer experience" in terms of application performance so that service levels can be verified against measurable and relevant data in a true end-to-end manner across both fixed and wireless networks Presents probe and agent technology Features a real-world scenario of how real time application performance monitoring can not only provide service level management but can also aid in root cause analysis - this will be of particular interest to practitioner Analyses which elements are required in order to deliver multimedia services across 2nd and 3rd generation mobile networks Details the components of data networking that will assist in guaranteeing service level performance Essential reading for Wireless and IP data network professionals/practitioners, network managers and architects, technical consultants, quality assessment engineers, infrastructure vendors, application developers, portal designers, wireline operators, lecturers, postgraduates, senior undergraduate students and industry trainees.

Book Description
The overwhelming majority of a software system’s lifespan is spent in use, not in design or implementation. So, why does conventional wisdom insist that software engineers focus primarily on the design and development of large-scale computing systems? In this collection of essays and articles, key members of Google’s Site Reliability Team explain how and why their commitment to the entire lifecycle has enabled the company to successfully build, deploy, monitor, and maintain some of the largest software systems in the world. You’ll learn the principles and practices that enable Google engineers to make systems more scalable, reliable, and efficient—lessons directly applicable to your organization. This book is divided into four sections: Introduction—Learn what site reliability engineering is and why it differs from conventional IT industry practices Principles—Examine the patterns, behaviors, and areas of concern that influence the work of a site reliability engineer (SRE) Practices—Understand the theory and practice of an SRE’s day-to-day work: building and operating large distributed computing systems Management—Explore Google's best practices for training, communication, and meetings that your organization can use

Book Description
Over a long period of time we were receiving demand from different customers and stakeholders requesting our help with analyzing actual levels of IT management practices in their companies and to provide an external, objective look at IT, compare it with other organizations and develop a management summary of our overall findings. While this seems like a straight forward request and is covered by many consulting service providers, we struggled to develop answers to some very simple questions which are crucial to the different management levels from CEO level to IT professionals delivering operational support to the end user. Key questions we were requested to answer: _ How good is our IT? _ How is the quality of our IT evolving? _ How do we compare with other IT departments in similar organizations? _ How do we align the perception of quality between the business and IT? _ Can you compare the quality and costs of our IT? There are many existing assessment approaches based on ISO/IEC, capability models, maturity models, structured surveys as well as there being many different benchmarking approaches that provide detailed analytical outputs. These are typically focused and targeted internally, providing largely internal benefits to a company’s IT organization, looking mostly at the presence of documentation and processes, but none of them providing a comprehensive and straight forward answer to address the simple yet fundamental question asked by management – HOW GOOD IS OUR IT? We believe that a simple question should have a simple answer.
