Practical, real-world solutions are given to potential problems covering the entire system life cycle. This book describes how to map real-life systems (databases, data centers, and e-commerce applications) into analytic performance models. The authors elaborate upon these models and use them to help the reader better understand performance issues.
This is a short, occasionally funny, book on how to solve and avoid application and/or computer performance problems. I wrote it to give back the knowledge, insights, tips, and tricks I was given over the last 25 years of my computing career. It shows practical ways to use key performance laws and gives well tested advice on how (and when) to do performance monitoring, capacity planning, load testing, and performance modeling. It works for any application or collection of computers because it teaches you how to decipher whatever meters they give you and how to discover more about those meters than the documentation reveals. This book covers the things that will always be true no matter what technology you are using. It will continue to be useful 20 years from now when today's technology, if it runs at all, will look as quaint as a mechanical cuckoo clock. There is no complex math required; yet it allows you to easily use some fairly advanced techniques. Simple arithmetic, and a spreadsheet program, is all that is required of you. Lastly, it helps with the human side of performance. It shows you how to get the help you need and how to present your findings (good or bad) all the way up to the CIO level.
Success on the web is measured by usage and growth. Web-based companies live or die by the ability to scale their infrastructure to accommodate increasing demand. This book is a hands-on and practical guide to planning for such growth, with many techniques and considerations to help you plan, deploy, and manage web application infrastructure. The Art of Capacity Planning is written by the manager of data operations for the world-famous photo-sharing site Flickr.com, now owned by Yahoo! John Allspaw combines personal anecdotes from many phases of Flickr's growth with insights from his colleagues in many other industries to give you solid guidelines for measuring your growth, predicting trends, and making cost-effective preparations. Topics include: Evaluating tools for measurement and deployment Capacity analysis and prediction for storage, database, and application servers Designing architectures to easily add and measure capacity Handling sudden spikes Predicting exponential and explosive growth How cloud services such as EC2 can fit into a capacity strategy In this book, Allspaw draws on years of valuable experience, starting from the days when Flickr was relatively small and had to deal with the typical growth pains and cost/performance trade-offs of a typical company with a Web presence. The advice he offers in The Art of Capacity Planning will not only help you prepare for explosive growth, it will save you tons of grief.

This IBM® RedpaperTM is the second in a series that addresses the performance and capacity considerations of the evolving cloud computing model. The first Redpaper publication (Performance Implications of Cloud Computing, REDP-4875) introduced cloud computing with its various deployment models, support roles, and offerings along with IT performance and capacity implications associated with these deployment models and offerings. In this redpaper, we discuss lessons learned in the two years since the first paper was written. We offer practical guidance about how to select workloads that work best with cloud computing, and about how to address areas, such as performance testing, monitoring, service level agreements, and capacity planning considerations for both single and multi-tenancy environments. We also provide an example of a recent project where cloud computing solved current business needs (such as cost reduction, optimization of infrastructure utilization, and more efficient systems management and reporting capabilities) and how the solution addressed performance and capacity challenges. We conclude with a summary of the lessons learned and a perspective about how cloud computing can affect performance and capacity in the future.
Covering topics from analysis tools to kernel tuning, to capacity management, this book offers a single point of reference for what you need to know. Anyone who has ever had to speed existing operations or project usage patterns for future loads, knows that tracking down the relevant information can be a difficult task. That's why this book has been written-it pulls together all of this knowledge, saving countless hours of what might otherwise be wasted research time.
Double your odds of leading successful, sustainable change Leaders aren’t short on access to change management advice, but the jury has long been out as to which approach is the best one to follow. With the publication of Beyond Performance 2.0, the verdict is well and truly in. By applying the approach detailed by authors, Scott Keller and Bill Schaninger, the evidence shows that leaders can more than double their odds of success—from thirty percent to almost eighty. Whereas the first edition of Beyond Performance introduced the authors’ “Five Frames of Performance and Health” approach to change management, the fully revised and updated Beyond Performance 2.0 has been transformed into a truly practical “how to” guide for leaders. Every aspect of how to lead change at scale is covered in a step-by-step manner, always accompanied by practical tools and real-life examples. Keller and Schaninger’s work is distinguished in many ways, one of which is the rigor behind the recommendations. The underpinning research is the most comprehensive of its kind—based on over 5 million data points drawn from 2,000 companies globally over a 15-year period. This data is overlaid with the authors’ combined more than 40 years of experience in helping companies successfully achieve large-scale change. As senior partners in McKinsey & Company, consistently named the world’s most prestigious management consulting firm, Keller and Schaninger also draw on the shared experience of their colleagues from offices in over 60 countries with unrivaled access to CEOs and senior teams. Beyond Performance 2.0 also dares to go against the grain—eschewing the notion of copying best practices and instead guiding leaders to make choices specific to their unique context and organization. It does this with meticulously balance of focus on short- and long-term considerations, and on fully addressing the hard technical and oft cultural elements of making change happen. Further, the approach doesn’t just focus on delivering change; it builds an organization’s muscle to continuously change, making it healthier so that it can act with increased speed and agility to stay perpetually ahead of its competition. Leaders looking for a proven approach to leading large-scale change from a trusted source have found what they are looking for in Beyond Performance 2.0.
Fathali M. Moghaddam's The Individual and Society explores the fascinating relationship between the individual and society through a multi-disciplinary approach, drawing from research in social psychology, sociology, political science, anthropology, cultural psychology, neuroscience, and cognitive psychology. From the Islamic revolution in Iran to the biology of depression, Dr. Moghaddam adeptly uses personal anecdotes and his unique views on society and psychology to bring a better understanding of how culture, society, and the individual interact.
This book attempts to shift focus from performance appraisals to performance management incorporating performance planning, analysis, and development as critical components of it. The performance management system (PMS) is a future-driven exercise rather than merely a past-reviewing exercise. Performance management is treated as a year-round practice and not an appraisal process conducted once a quarter or annually. Moreover, it is now considered to be everyone’s responsibility and not merely that of HR or the upper management. This book advocates the structuring of PMSs and their implementation. It incorporates the most modern 360-degree feedback systems and shows the ways and means of integrating it into PMS. Arguments are offered to use rating-less appraisals and/or a combination of appraisals with 360-degree feedback. It defines performance management to mean continuous improvements in performance of individuals, their teams, departments, and corporations. It also outlines that planning, analysis, review, coaching, and capability building are essential building blocks for good performance management. Concise, lucid, and engaging, this volume would be useful to the students, researchers, and faculty of human resource management, organizational behaviour and applied psychology. It would also be an invaluable guidebook for practicing business executives and HR professionals to help them implement the performance management system for effective talent management leading to increased productivity.
