Load Balancing in the Cloud
Use of redundant servers has long been a solution for meeting sudden spikes in demand, machine failures, and outages. Cloud services greatly reduce the cost and hassle of provisioning redundant equipment and load balancers and give you the ability to deal with separate network, application, and client-side loads. But today there are many options to consider, and you have to determine which cloud service (or services) will meet your company's unique needs. With this ebook, author Derek DeJonghe from RightBrain Networks delivers a practical guide to load balancing services in the cloud. In this dynamic environment, where machines are frequently provisioned and decommissioned to meet user demand, you need a load balancer that can intelligently distribute traffic. This ebook walks you through the several options, including the use of the NGINX software load balancer. ...

.NET Performance Testing and Optimization
As we develop the applications to meet current and future needs, it is only natural to use current best practices and techniques for our designs and implementations. In the quest to improve how we develop, we can access a true wealth of information which is available on design patterns, object-oriented analysis, low-level code techniques and language features. The technology community is full of articles, blog posts, books, and videos describing things such as generics, how to implement the observer pattern, LINQ to SQL techniques, CSS tricks, and a host of other topics. These points are often easily described in a single post or article, wherein a thorough dissemination of the technique can be presented, and readers and viewers can quickly gain a much better understanding of the technique or point in question. Indeed, when broken down into individual and easily digestible components, almost anything complex becomes much easier to grasp. From the point of view of sophisticated de ...

Machine Learning Techniques for Text
With the ever-increasing demand for machine learning and programming professionals, it's prime time to invest in the field. This book will help you in this endeavor, focusing specifically on text data and human language by steering a middle path among the various textbooks that present complicated theoretical concepts or focus disproportionately on Python code. A good metaphor this work builds upon is the relationship between an experienced craftsperson and their trainee. Based on the current problem, the former picks a tool from the toolbox, explains its utility, and puts it into action. This approach will help you to identify at least one practical use for each method or technique presented. The content unfolds in ten chapters, each discussing one specific case study. For this reason, the book is solution-oriented. It's accompanied by Python code in the form of Jupyter notebooks to help you obtain hands-on experience. A recurring pattern in the chapters of this book is helping you ...

Managing Kubernetes Traffic with F5 Nginx
Microservices architectures introduce several benefits to the application development and delivery process. Microservices-based apps are easier to build, test, maintain, and scale. They also reduce downtime through better fault isolation. While container-based microservices apps have profoundly changed the way DevOps teams deploy applications, they have also introduced challenges. Kubernetes - the de facto container orchestration platform - is designed to simplify management of containerized apps, but it has its own complexities and a steep learning curve. This is because responsibility for many functions that traditionally run inside an app (security, logging, scaling, and so on) are shifted to the Kubernetes networking fabric. To manage this complexity, DevOps teams need a data plane that gives them control of Kubernetes networking. The data plane is the key component that connects microservices to end users and each other, and managing it effectively is critical to achieving s ...

Modern Concurrency on Apple Platforms
Build solid software with modern and safe concurrency features. Concurrency is one of the hardest problems in computer science. For years, computer scientists and engineers have developed different strategies for dealing with concurrency. However, the original concurrency primitives are complicated and difficult to understand, and even harder to implement. Using the new async/await APIs in Swift, this book will explain how your code can abstract a lot of the complexity with a simpler interface so you never have to deal with concurrency primitives such as semaphores, locks, and threads yourself. This will allow you to write concurrent code that is easier to read, easier to write, and easier to maintain. These new APIs are deeply ingrained into Swift, offering compile-level features that will keep you from writing dangerous concurrent code. You'll start by exploring why concurrency is hard to implement in a traditional system. Explaining the definition of concurrency and what its pri ...

Workload Automation Using HWA
Apply best practices for deploying and administering HCL Workload automation (HWA) to meet the automation requirements of the digitally transformed platform. This book will provide detailed architecture and deployment options to achieve this goal. Workload automation focuses on real-time processing, predefined event-driven triggers, and situational dependencies. It offers centralized control of managing multiple tasks, making it possible to schedule enterprise-wide tasks. You'll see how it supports the timely completion of tasks and is beneficial for processes that need to happen at a specific time or need to occur as a result of another event. HWA increases efficiency, reduces the turnaround time for workflows, and reduces errors along with delays in end-to-end processes. You'll review proven ways to deliver batch optimization and modernization requirements, and see how solutions can be aligned with the DevSecOps delivery model.
