Every day, companies struggle to scale critical applications. As traffic volume and data demands increase, these applications become more complicated and brittle, exposing risks and compromising availability. This practical guide shows IT, devops, and system reliability managers how to prevent an application from becoming slow, inconsistent, or downright unavailable as it grows. Scaling isn’t just about handling more users; it’s also about managing risk and ensuring availability. Author Lee Atchison provides basic techniques for building applications that can handle huge quantities of traffic, data, and demand without affecting the quality your customers expect. In five parts, this book explores: Availability: learn techniques for building highly available applications, and for tracking and improving availability going forward Risk management: identify, mitigate, and manage risks in your application, test your recovery/disaster plans, and build out systems that contain fewer risks Services and microservices: understand the value of services for building complicated applications that need to operate at higher scale Scaling applications: assign services to specific teams, label the criticalness of each service, and devise failure scenarios and recovery plans Cloud services: understand the structure of cloud-based services, resource allocation, and service distribution
In their early days, Twitter, Flickr, Etsy, and many other companies experienced sudden spikes in activity that took their web services down in minutes. Today, determining how much capacity you need for handling traffic surges is still a common frustration of operations engineers and software developers. This hands-on guide provides the knowledge and tools you need to measure, deploy, and manage your web application infrastructure before you experience explosive growth. In this thoroughly updated edition, authors Arun Kejariwal (MZ) and John Allspaw provide a systematic, robust, and practical approach to capacity planning—rather than theoretical models—based on their own experiences and those of many colleagues in the industry. They address the vast sea change in web operations, especially cloud computing.

To help architects and developers make the most of these technologies, SOA with .NET and Azure contains multiple examples drawn from the authors' unsurpassed personal SOA implementation experience, as well as a full chapter of case studies.
In our current healthcare system, many people and employers are struggling to find affordable, convenient care. Costs continue to rise, and the growing physician shortage has led to increasingly long wait times to get care. To address these issues, we must find innovative ways to facilitate hassle-free, cost-effective access to doctors. Technology has revolutionized almost every industry in the modern world. It changes the way we drive, the way we communicate, the way we eat and sleep, and even the fabric of the traditional 8 to 5 workdays. It is hard to imagine not being able to instantly text or call someone on the other side of the country or not being able to check your email while in the car. Almost every aspect of modern life has been made faster and more convenient through telecommunications technology. Except health care. Even as technology has improved, access to health care has worsened for many Americans. The Affordable Care Act may have increased the number of people with health insurance, but the fact is that health care remains unaffordable and inconvenient for most people. An increasing percentage of health insurance plans have expensive premiums, sky-high deductibles, and costly copays. People are paying for care that they can hardly afford to use. Plus, physician shortages mean absurdly long wait times, especially in crowded cities. Patients are resorting to urgent cares and emergency rooms, making care even more expensive. Patients in rural areas face an even greater challenge: rural hospitals are closing, meaning long drive times and limited access to specialists in their area. Employers are also struggling with rising costs. Unable to sustain their current benefit levels, they have been forced to reduce benefits and shift health care costs to employees through higher premiums, deductibles, and copays. Technological advances have done little to help these worrying trends. But there is a solution that could help millions of Americans get more affordable, convenient access to care: telehealth. Telehealth is a solution that helps combat these trends, but it has not yet lived up to its expectations. Many of the current products in the market are ineffective, because brokers, insurance companies, and major telehealth companies are more concerned with their own profits than with providing real solutions. But with more education and utilization, telehealth could revolutionize the healthcare industry and provide better access to care for millions of Americans that need it. "Telehealth," put simply, means using telecommunications technology to provide remote care. The term encompasses any use of telecommunications technology in the medical field, even faxing a prescription to a pharmacy, but typically when people use the word "telehealth" or "telemedicine," they are talking about virtual doctor visits. With these telehealth services, patients can call or video conference with a doctor instead of going into a physicians' office, urgent care, or other site of care. The doctors can diagnosis, treat, and manage illnesses and other medical conditions remotely. This lowers the overall cost to deliver care as well as reduces the total time involved for the patient and provider. Telehealth brings the medical care to the patient, wherever they are. It enables patients to get the care they need, without sacrificing valuable time or money to get it. Most importantly, the book is based on the recognition that patients need better health care options and telehealth is vital to health care's future if delivered properly.

Since the first DIISM conference, which took place 9 years ago, the world has seen drastic changes, including the transformation of manufacturing and engineering software, and the information and communication technologies deployed. The conditions for manufacturing and engineering have changed on a large scale, in terms of technology-enabled collaboration among the fields of design, engineering, production, usage, maintenance and recyclingldisposal. These changes can be observed in rapidly-growing fields such as supply chain management. As for production technologies at factory floors, new visions on human-machine co-existing systems involve both knowledge management and multi-media technologies. Therefore, because of these changes, the importance of information infrastructure for manufacturing has increased, stunningly. Information infrastructure plays a key role in integrating diverse fields of manufacturing, engineering and management. This, in addition to its basic role, as the information and communication platform for the production systems. Eventually, it should also serve the synthetic function of knowledge management, during the life cycles of both the production systems and their products, and for all stakeholders.
