Download or read book The Art of Capacity Planning written by John Allspaw and published by "O'Reilly Media, Inc.". This book was released on 2008-09-23 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Guerrilla Capacity Planning written by Neil J. Gunther and published by Springer Science & Business Media. This book was released on 2007-01-17 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Under today’s shortened fiscal horizons and contracted time-to-market schedules, traditional approaches to capacity planning are seen by management as inflating production schedules. In the face of relentless pressure to get things done faster, this book facilitates rapid forecasting of capacity requirements, based on opportunistic use of available performance data and tools so that management insight is expanded but production schedules are not. The book introduces such concepts as an iterative cycle of improvement called "The Wheel of Capacity Planning," and Virtual Load Testing, which provides a highly cost-effective method for assessing application scalability.

Download or read book Performance and Capacity Themes for Cloud Computing written by Elisabeth Stahl and published by IBM Redbooks. This book was released on 2013-03-20 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Cloud Capacity Management written by Navin Sabharwal and published by Apress. This book was released on 2013-08-26 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cloud Capacity Management helps readers in understanding what the cloud, IaaS, PaaS, SaaS are, how they relate to capacity planning and management and which stakeholders are involved in delivering value in the cloud value chain. It explains the role of capacity management for a creator, aggregator, and consumer of cloud services and how to provision for it in a 'pay as you use model'. This involves a high level of abstraction and virtualization to facilitate rapid and on demand provisioning of services. The conventional IT service models take a traditional approach when planning for service capacity to provide optimum services levels which has huge cost implications for service providers. This book addresses the gap areas between traditional capacity management practices and cloud service models. It also showcases capacity management process design and implementation in a cloud computing domain using ITSM best practices. This book is a blend of ITSM best practices and infrastructure capacity planning and optimization implementation in various cloud scenarios. Cloud Capacity Management addresses the basics of cloud computing, its various models, and their impact on capacity planning. This book also highlights the infrastructure capacity management implementation process in a cloud environment showcasing inherent capabilities of tool sets available and the various techniques for capacity planning and performance management. Techniques like dynamic resource scheduling, scaling, load balancing, and clustering etc are explained for implementing capacity management.

Download or read book Hospital Capacity Management written by Robbin Dick and published by CRC Press. This book was released on 2021-03-19 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hospital Capacity Management: Insights and Strategies details many of the key processes, procedures, and administrative realities that make up the healthcare system we all encounter when we visit the ED or the hospital. It walks through, in detail, how these systems work, how they came to be this way, why they are set up as they are, and then, in many cases, why and how they should be improved right now. Many examples pulled from the lifelong experiences of the authors, published studies, and well-documented case studies are provided, both to illustrate and support arguments for change. First and foremost, it is necessary to remember that the mission of our healthcare system is to take care of patients. This has been forgotten at times, causing many of the issues the authors discuss in the book including hospital capacity management. This facet of healthcare management is absolutely central to the success or failure of a hospital, both in terms of its delivery of care and its ability to survive as an institution. Poor hospital capacity management is a root cause of long wait times, overcrowding, higher error rates, poor communication, low satisfaction, and a host of other commonly experienced problems. It is important enough that when it is done well, it can completely transform an entire hospital system. Hospital capacity management can be described as optimizing a hospital’s bed availability to provide enough capacity for efficient, error-free patient evaluation, treatment, and transfer to meet daily demand. A hospital that excels at capacity management is easy to spot: no lines of people waiting and no patients in hallways or sitting around in chairs. These hospitals don’t divert incoming ambulances to other hospitals; they have excellent patient safety records and efficiently move patients through their organization. They exist but are sadly in the minority of American hospitals. The vast majority are instead forced to constantly react to their own poor performance. This often results in the building of bigger and bigger institutions, which, instead of managing capacity, simply create more space in which to mismanage it. These institutions are failing to resolve the true stumbling blocks to excellent patient care, many of which you may have experienced firsthand in your own visit to your hospital. It is the hope of the authors that this book will provide a better understanding of the healthcare delivery system.
