A step-by-step guide to Istio Service Mesh implementation, with examples of complex and distributed workloads built using microservices architecture and deployed in Kubernetes Purchase of the print or Kindle book includes a free PDF eBook Key Features Learn the design, implementation, and troubleshooting of Istio in a clear and concise format Grasp concepts, ideas, and solutions that can be readily applied in real work environments See Istio in action through examples that cover Terraform, GitOps, AWS, Kubernetes, and Go Book Description Istio is a game-changer in managing connectivity and operational efficiency of microservices, but implementing and using it in applications can be challenging. This book will help you overcome these challenges and gain insights into Istio's features and functionality layer by layer with the help of easy-to-follow examples. It will let you focus on implementing and deploying Istio on the cloud and in production environments instead of dealing with the complexity of demo apps. You'll learn the installation, architecture, and components of Istio Service Mesh, perform multi-cluster installation, and integrate legacy workloads deployed on virtual machines. As you advance, you'll understand how to secure microservices from threats, perform multi-cluster deployments on Kubernetes, use load balancing, monitor application traffic, implement service discovery and management, and much more. You'll also explore other Service Mesh technologies such as Linkerd, Consul, Kuma, and Gloo Mesh. In addition to observing and operating Istio using Kiali, Prometheus, Grafana and Jaeger, you'll perform zero-trust security and reliable communication between distributed applications. After reading this book, you'll be equipped with the practical knowledge and skills needed to use and operate Istio effectively. What you will learn Get an overview of Service Mesh and the problems it solves Become well-versed with the fundamentals of Istio, its architecture, installation, and deployment Extend the Istio data plane using WebAssembly (Wasm) and learn why Envoy is used as a data plane Understand how to use OPA Gatekeeper to automate Istio's best practices Manage communication between microservices using Istio Explore different ways to secure the communication between microservices Get insights into traffic flow in the Service Mesh Learn best practices to deploy and operate Istio in production environments Who this book is for The book is for DevOps engineers, SREs, cloud and software developers, sysadmins, and architects who have been using microservices in Kubernetes-based environments. It addresses challenges in application networking during microservice communications. Working experience on Kubernetes, along with knowledge of DevOps, application networking, security, and programming languages like Golang, will assist with understanding the concepts covered.

This book is about helping entrepreneurs sift through the "noise" regarding bootstrapping a start-up. Ultimately, the cold-hard facts on bootstrapping will be presented. Practically speaking, most entrepreneurs should avoid bootstrapping. However, realistically, most entrepreneurs will need to engage in some form of bootstrapping. The argument then, importantly, shifts to how should one bootstrap? In this era of lean start-ups, effectuation, and bricolage, bootstrapping is oft romanticized but seldom analyzed. This book is different from other bootstrapping books in two key ways. First, it draws on evidence from scientific study to offer best practices. Second, it utilizes this evidence to help entrepreneurs thrive-- not just survive.

This article evaluates the effect of the overdraft facility (or line of credit) policy by comparing a large sample of overdraft facilitated firms and matched non-overdraft facilitated firms from Eastern Europe at the sector level. The sample firms are compared with respect to rates of different performance indicators including: technical efficiency (a Data Envelopment Analysis approach is applied to estimate the technical efficiency level for individual sectors), production workers trained, expenditures on research and development, and export activity. In order to avoid the selectivity problem, propensity score matching methodologies are adopted. The results suggest that a certain level of overdraft facility provided to firms would be needed to stimulate investment in research and development, which will eventually result in increased growth in productivity.

Find the right bootloader solution or combination of firmware required to boot a platform considering its security, product features, and optimized boot solutions. This book covers system boot firmware, focusing on real-world firmware migration from closed source to open source adaptation. The book provides an architectural overview of popular boot firmware. This includes both closed sourced and/or open source in nature, such as Unified Extensible Firmware Interface (UEFI), coreboot, and Slim Bootloader and their applicable market segments based on product development and deployment requirements. Traditional system firmware is often complex and closed sourced whereas modern firmware is still a kind of hybrid between closed and open source. But what might a future firmware model look like? The most simplistic boot firmware solution uses open source firmware development. This book helps you decide how to choose the right boot firmware for your products and develop your own boot firmware using open source. Coverage includes: Why open source firmware is used over closed source The pros and cons of closed and open source firmware A hybrid work model: for faster bring-up activity using closed source, binary integrated with open source firmware What You Will Learn Understand the architecture of standard and popular boot firmware Pick the correct bootloader for your required target hardware Design a hybrid workflow model for the latest chipset platform Understand popular payload architectures and offerings for embedded systems Select the right payload for your bootloader solution to boot to the operating system Optimize the system firmware boot time based on your target hardware requirement Know the product development cycle using open source firmware development.

In this book, Ernest Sosa explains the nature of knowledge through an approach originated by him years ago, known as virtue epistemology. Here he provides the first comprehensive account of his views on epistemic normativity as a form of performance normativity on two levels. On a first level is found the normativity of the apt performance, whose success manifests the performer's competence. On a higher level is found the normativity of the meta-apt performance, which manifests not necessarily first-order skill or competence but rather the reflective good judgment required for proper risk assessment. Sosa develops this bi-level account in multiple ways, by applying it to issues much disputed in recent epistemology: epistemic agency, how knowledge is normatively related to action, the knowledge norm of assertion, and the Meno problem as to how knowledge exceeds merely true belief. A full chapter is devoted to how experience should be understood if it is to figure in the epistemic competence that must be manifest in the truth of any belief apt enough to constitute knowledge. Another takes up the epistemology of testimony from the performance-theoretic perspective. Two other chapters are dedicated to comparisons with ostensibly rival views, such as classical internalist foundationalism, a knowledge-first view, and attributor contextualism. The book concludes with a defense of the epistemic circularity inherent in meta-aptness and thereby in the full aptness of knowing full well.
