Although microservices-based applications support DevOps and continuous delivery, they can also add to the complexity of testing and observability. The implementation of a service mesh architecture, however, allows you to secure, manage, and scale your microservices more efficiently. With the help of practical examples, this book demonstrates how to install, configure, and deploy an efficient service mesh for microservices in a Kubernetes environment.You'll get started with a hands-on introduction to the concepts of cloud-native application management and service mesh architecture, before learning how to build your own Kubernetes environment. While exploring later chapters, you'll get to grips with the three major service mesh providers: Istio, Linkerd, and Consul. You'll be able to identify their specific functionalities, from traffic management, security, and certificate authority through to sidecar injections and observability.By the end of this book, you will have developed the skills you need to effectively manage modern microservices-based applications.

Industry giants like RedHat and NetApp have adopted ServiceNow for their operational needs, and it is evolving as the number one platform choice for IT Service management. ServiceNow provides their clients with an add-on when it comes to baseline instances, where scripting can be used to customize and improve the performance of instances. It also provides inbuilt JavaScript API for scripting and improving your JavaScript instance.This book will initially cover the basics of ServiceNow scripting and the appropriate time to script in a ServiceNow environment. Then, we dig deeper into client-side and server-side scripting using JavaScipt API. We will also cover advance concepts like on-demand functions, script actions, and best practices. Mastering ServiceNow Scripting acts as an end-to-end guide for writing, testing, and debugging scripts of ServiceNow. We cover update sets for moving customizations between ServiceNow instances, jelly scripts for making custom pages, and best practices for all types of script in ServiceNow.By the end of this book, you will have hands-on experience in scripting ServiceNow using inbuilt JavaScript API.

SFML is a cross-platform software development library written in C++ with bindings available for many programming languages. It provides a simple interface to the various components of your PC, to ease the development of games and multimedia applications. This book will help you become an expert of SFML by using all of its features to its full potential. It begins by going over some of the foundational code necessary in order to make our RPG project run. By the end of chapter 3, we will have successfully picked up and deployed a fast and efficient particle system that makes the game look much more ‘alive’. Throughout the next couple of chapters, you will be successfully editing the game maps with ease, all thanks to the custom tools we’re going to be building. From this point on, it’s all about making the game look good. After being introduced to the use of shaders and raw OpenGL, you will be guided through implementing dynamic scene lighting, the use of normal and specular maps, and dynamic soft shadows. However, no project is complete without being optimized first. The very last chapter will wrap up our project by making it lightning fast and efficient.
