Book Description
The objective of APM Best Practices: Realizing Application Performance Management is to establish reliable application performance management (APM) practices—to demonstrate value, to do it quickly, and to adapt to the client circumstances. It's important to balance long-term goals with short-term deliverables, but without compromising usefulness or correctness. The successful strategy is to establish a few reasonable goals, achieve them quickly, and then iterate over the same topics two more times, with each successive iteration expanding the skills and capabilities of the APM team. This strategy is referred to as “Good, Better, Best”. The application performance monitoring marketplace is very focused on ease of installation, rapid time to usefulness, and overall ease of use. But these worthy platitudes do not really address the application performance management processes that ensure that you will deploy effectively, synergize on quality assurance test plans, triage accurately, and encourage collaboration across the application life cycle that ultimately lowers overall application cost and ensures a quality user experience. These are also fine platitudes but these are the ones that are of interest to your application sponsors. These are the ones for which you need to show value. This CA Press book employs this iterative approach, adapted pragmatically for the realities of your organizational and operational constraints, to realize a future state that your sponsors will find useful, predictable and manageable—and something that they will want to fund. In the meantime, you will learn the useful techniques needed to set up and maintain a useful performance management system utilizing best practices regardless of the software provider(s).

Book Description
Pro PHP Application Performance will help you understand all the technologies and components which play a role in how well your applications run. When seconds can mean the difference between retaining a user and losing a user, it's important for all of us to have optimization as part of our project roadmap. But what components within your application should you analyze? How should you optimize? And how can you measure how well your application is performing? These are some of the questions that are answered in this book. Along the way you will also learn the "why" of optimizing. You’ll discover why you should optimize a specific component, why selecting one function over another is beneficial, and how to find and use the optimization tools available to the open source community. You’ll also learn how to deploy caching software as well as web server software. Pro PHP Application Performance will also teach you more advanced techniques, such as: • Using Xdebug to profile functions that are not running as efficiently as possible. • Comparing opcode executed by different PHP functions to narrow the search for functions that run efficiently. • Using strace to analyze Apache while your application is served to the user. Once you complete this book you will have a complete sense of where to start optimizing and, most importantly, have the tools which allow you to continue optimizing in other PHP applications going forward.

Book Description
Inhaltsangabe:Introduction: Despite the widespread recognition that performance is important to the success of a project, many software products fail to respond fast enough to user requests or to handle a certain amount of parallel business transactions. This is because nowadays projects are result-oriented where the focus is on functionality to be implemented. Such projects do not pay high attention to application performance because it still does not have the particular importance that unit testing for example has. Moreover today s development models usually consider performance management only in a limited way within their lifecycle and often follow what is known as the fix it later approach. The fix it later approach concentrates on software correctness and defers performance considerations to the integration testing phase where additional hardware is added or a system is tuned when performance issues are detected. The problem of neglecting performance management is that performance issues often do not emerge until an application is put into production, where it is likely to suffer the consequences of a performance failure. The consequences of performance failures can be increased operational costs, increased development and hardware costs, and damaged customer relations. If severe performance issues are discovered during production, it may be too expensive to re-design a system or even impossible to add additional hardware in order to meet performance objectives. Such projects are likely to be canceled and their costs will be unrecoverable. To avoid such situations, performance management should be integrated into an application s lifecycle from the beginning. This means that performance objectives have to be defined early within a project and continually verified as an application evolves. Having performance management integrated from the beginning allows to reduce overall project risk and costs because performance issues can be spotted and corrected early in the lifecycle and even before end users are affected. Furthermore an application is extensively tested for its ability of reaching performance objectives before it is deployed to a production environment and exposed to real users. NovaTec GmbH is a company providing IT-services in the area of consulting, project management, software engineering, application architectures, provisioning, performance management, and process engineering. The competences of NovaTec are logically grouped in [...]

Book Description
One in five U.S. adults experiences a mental illness within a given year. With more than 550,000 people working to support this underserved community, the mental healthcare system has grappled with inadequacies and shortcomings in safety, quality, and care delivery. There is a wide range of problems, from access-to-care issues and errors, to complications stemming from poor care. Our country is also on an unsustainable path as our healthcare expenditure keeps growing. To add to all of this, we are facing a rampant epidemic of burnout among healthcare workers. Modern advancements introduced with many promises—such as electronic medical records, newer medications, or advanced treatments—have created unique challenges when ushered into a highly regulated healthcare system. What does it take to provide patients with everything they need—the right quality of care, at the right time, and at the right cost—to keep them healthy? Which process steps add value? Which steps are wasteful? A widely accepted fact is that a conservative 30-50% of every step in the mental healthcare process does not help patients feel better or stay better. When considering delays in care, workarounds, excessive documentation, and an overuse of auditing, the care system has moved highly skilled clinicians away from providing value, as administrative tasks continue to encroach on their time. There is a clear need to rethink and redesign the system of care. This book is a primer for understanding the current state of the mental health system and the performance improvement skills and leadership acumen needed to address existing challenges. Sheppard Pratt, the award-winning, leading institution for mental healthcare in America, provided the focus on mental healthcare and became the laboratory for this body of work over the course of eight years. It hired a seasoned systems thinker with improvement expertise to work with mental health professionals and solve some of their most complex and chronic problems. The book is a result of the collaboration between a practicing psychiatrist in a leadership role and the systems engineer. Working together, they demonstrate how to think about redesigning care and redefining the nature of work to enhance value for both the people served and the healthcare workforce. They crafted a multi-pronged approach towards culture change at Sheppard Pratt, including implementing a course on "Learning to Improve," which introduced staff to a performance improvement methodology. There are several vignettes interwoven throughout the book that describe the complexities and constraints of the system. Solving some of these challenges creates a new paradigm of work while minimizing waste and enhancing value.

Book Description
In a world of data deluge, considerable computational power is necessary to derive knowledge from the mountains of raw data which surround us. This trend mandates the use of various parallelization techniques and runtimes to perform such analyses in a meaningful period of time. The information retrieval community has introduced a programming model and associated runtime architecture under the name of MapReduce, and it has demonstrated its applicability to several major operations performed by and within this community. Our initial research demonstrated that, although the applicability of MapReduce is limited to applications with fairly simple parallel topologies, with a careful set of extensions, the programming model can be extended to support more classes of parallel applications; in particular, this holds true for the class of Composable Applications.
