The Second Edition of The SAGE Handbook of Leadership provides not only an in-depth overview the current field of leadership studies, but also a map into the future debates, innovations and priorities of where the field will move to. Featuring all new chapters from a global community of leading and emerging scholars, each chapter offers a comprehensive, critical overview of an aspect of leadership, a discussion of key debates and research, and a review of the emerging issues in its area. Featuring an innovative structure divided by prepositions, this brand-new edition moves away from essentializing boundaries, and instead seeks to create synergies between different schools of leadership. A key feature of the second edition, is the attention to sensemaking (exploring the current themes, structures and ideas that comprise each topic) and sensebreaking (disrupting, critiquing and refreshing each topic). Suitable for students and researchers alike, this second edition is a critical site of reference for the study of leadership. PART 1: Between: Leadership as a Social, Socio-cognitive and Practical Phenomenon PART 2: About: Exploring the Individual and Interpersonal Facets of Leadership PART 3: Through: Leadership Seen Through Contemporary Frames PART 4: Within: Leadership as a Contextually Bound Phenomenon PART 5: But: A Critical Examination of Leadership

Create and deploy production-quality microservices-based applications - New edition updated for the smooth running of Spring, Java, Kubernetes, and Istio, with an introduction to Helm 3 and support for Mac and Windows with WSL2 Key Features Build cloud-native production-ready microservices with this comprehensively updated guide Understand the challenges of building large-scale microservice architectures Learn how to get the best out of Spring Cloud, Kubernetes, and Istio in combination Book DescriptionWant to build and deploy microservices, but don't know where to start? Welcome to Microservices with Spring Boot and Spring Cloud. This edition features the most recent versions of Spring, Java, Kubernetes, and Istio, demonstrating faster and simpler handling of Spring Boot, local Kubernetes clusters, and Istio installation. The expanded scope includes native compilation of Spring-based microservices, support for Mac and Windows with WSL2, and an introduction to Helm 3 for packaging and deployment. A revamped security chapter now follows the OAuth 2.1 specification and makes use of the newly launched Spring Authorization Server from the Spring team. You'll start with a set of simple cooperating microservices, then add persistence and resilience, make your microservices reactive, and document their APIs using OpenAPI. Next, you'll learn how fundamental design patterns are applied to add important functionality, such as service discovery with Netflix Eureka and edge servers with Spring Cloud Gateway. You'll deploy your microservices using Kubernetes and adopt Istio, then explore centralized log management using the Elasticsearch, Fluentd, and Kibana (EFK) stack, and then monitor microservices using Prometheus and Grafana. By the end of this book, you'll be building scalable and robust microservices using Spring Boot and Spring Cloud. What you will learn Build reactive microservices using Spring Boot Develop resilient and scalable microservices using Spring Cloud Use OAuth 2.1/OIDC and Spring Security to protect public APIs Implement Docker to bridge the gap between development, testing, and production Deploy and manage microservices with Kubernetes Apply Istio for improved security, observability, and traffic management Write and run automated microservice tests with JUnit, testcontainers, Gradle, and bash Who this book is forIf you're a Java or Spring Boot developer learning how to build microservice landscapes from scratch, then this book is for you. You don't need any prior knowledge about microservices architecture to get started, but a solid grasp and enough experience in Java and Spring Boot to build apps autonomously is a must.

Apply microservices patterns to build resilient and scalable distributed systems Key Features Understand the challenges of building large-scale microservice landscapes Build cloud-native production-ready microservices with this comprehensive guide Discover how to get the best out of Spring Cloud, Kubernetes, and Istio when used together Book DescriptionMicroservices architecture allows developers to build and maintain applications with ease, and enterprises are rapidly adopting it to build software using Spring Boot as their default framework. With this book, you'll learn how to efficiently build and deploy microservices using Spring Boot. This microservices book will take you through tried and tested approaches to building distributed systems and implementing microservices architecture in your organization. Starting with a set of simple cooperating microservices developed using Spring Boot, you'll learn how you can add functionalities such as persistence, make your microservices reactive, and describe their APIs using Swagger/OpenAPI. As you advance, you'll understand how to add different services from Spring Cloud to your microservice system. The book also demonstrates how to deploy your microservices using Kubernetes and manage them with Istio for improved security and traffic management. Finally, you'll explore centralized log management using the EFK stack and monitor microservices using Prometheus and Grafana. By the end of this book, you'll be able to build microservices that are scalable and robust using Spring Boot and Spring Cloud. What you will learn Build reactive microservices using Spring Boot Develop resilient and scalable microservices using Spring Cloud Use OAuth 2.0/OIDC and Spring Security to protect public APIs Implement Docker to bridge the gap between development, testing, and production Deploy and manage microservices using Kubernetes Apply Istio for improved security, observability, and traffic management Who this book is forThis book is for Java and Spring developers and architects who want to learn how to break up their existing monoliths into microservices and deploy them either on-premises or in the cloud using Kubernetes as a container orchestrator and Istio as a service Mesh. No familiarity with microservices architecture is required to get started with this book.
