Book Description This book is a part of Knoldus Reactive Programming Series. Few years ago, applications were much simpler and required all solutions at one place, we call them monolithic applications. Now a days markets are changing rapidly. You either adapt quickly or you go out of business. If your application is successful, you will start enhancing features day by day and as a result, your application becomes complex day by day and that complexity creates challenges in development. It will be difficult to fully understand and made changes fast and correctly. You must redeploy the entire application on each update. These type of application also has a barrier to adopting new technologies because it will affect the entire application. In this book, you will learn how you can manage this problem by dividing project into smaller pieces. You will learn how quickly you can start transforming your monolithic application into microservices. Microservice can be developed using different programming language (Personally I don't suggest to do it). I prefer Akka HTTP because it is fully integrated into Typesafe stack. Since there are already a lot of scala frameworks to build REST APIs then the obvious question is Why Akka HTTP? There are many reasons to use Akka HTTP, which you will learn in this book. I have written this book for those who want to start developing REST API right away and have a basic understanding of Scala. I don't exhaustively list all feature of Akka HTTP. I don't make you suffer through long and contrived example. I have tried to explain every topic of this book with short and easy to understand examples with test-cases.Akka HTTP is available for both Java and Scala but in this book, we will go with Scala. I choose Scala because it cuts down on boilerplate and we can concentrate on the logic of our problems. In Scala, you are not limited to just object-oriented patterns to implement your code, you can bring in functional paradigms as well. What You'll Learn Advantage of using Microservices architecture over monolithic Introduction to Akka HTTP Start coding in Akka HTTP Powerful JSON (un)marshalling support How to build server-side API How to build client-side API WebSocket support using Akka HTTP By the end of the book, you will get the links of multiple sample projects of Akka HTTP. For ex.:Akka HTTP with SOLRAkka HTTP with SlickAkka HTTP with Neo4J You will also get templates with frameworks like Angular.js, Spark Et al. You can clone these sample projects according to your requirement and start playing with restful web services. Who This Book Is For Those who want to start working on microservices architecture right away. The only pre-requisite to this book is that you are "comfortable" with Scala. However language is not a bar, even if you want to develop java microservices using Akka HTTP, you can still read this book to understand the concept. I have used the latest version of Akka HTTP in this book. About The Author Ayush Kumar Mishra is a Lead Scala Consultant based in Singapore. He is currently working with Knoldus, an organization where knowledge sharing and upskilling each Knolder is a way of life, which is the only organization to be partners with Lightbend, Databricks, Confluent and Datastax to deliver high-quality reactive products to its global clients. He has been working in Scala for more than 5 years. He loves to troubleshoot complex problems and look for the best solutions. In his career, he has successfully developed and delivered various microservice based systems with Scala and Akka HTTP. When he is not programming, he writes technical blogs. Most of his blogs are related to rest api design. He has also transformed some monolithic systems into microservice based system.

This Special Publication combines results obtained by interdisciplinary groups from numerous academic institutions working on Paleoproterozoic formations to decipher the origins of the main mineralization resources in the West African Craton (WAC) and their impacts on African economic development. Structural, geophysical, sedimentological, stratigraphical, geochemical, petrophysical and mineralogical analyses have been used to highlight the complexities involved in mineralization emplacement and its origin and evolution within the WAC. Fourteen articles contribute to new knowledge in mineral research. They show that the geodynamic evolution of the WAC is complex from one area to another: it involves subduction, collision and obduction during several deformation phases ranging from Birimian (2.3–2.0 Ga) to Pan-African (650–450 Ma) events. Various modelling techniques, when integrated, help in understanding the mechanisms of mineralization emplacement, some of which are still a matter of debate. The challenge for further studies is mitigation for sustainable development that can be appropriately used to minimize such damage.

Understand the key challenges and solutions around building microservices in the enterprise application environment. This book provides a comprehensive understanding of microservices architectural principles and how to use microservices in real-world scenarios. Architectural challenges using microservices with service integration and API management are presented and you learn how to eliminate the use of centralized integration products such as the enterprise service bus (ESB) through the use of composite/integration microservices. Concepts in the book are supported with use cases, and emphasis is put on the reality that most of you are implementing in a “brownfield” environment in which you must implement microservices alongside legacy applications with minimal disruption to your business. Microservices for the Enterprise covers state-of-the-art techniques around microservices messaging, service development and description, service discovery, governance, and data management technologies and guides you through the microservices design process. Also included is the importance of organizing services as core versus atomic, composite versus integration, and API versus edge, and how such organization helps to eliminate the use of a central ESB and expose services through an API gateway. What You'll LearnDesign and develop microservices architectures with confidence Put into practice the most modern techniques around messaging technologies Apply the Service Mesh pattern to overcome inter-service communication challenges Apply battle-tested microservices security patterns to address real-world scenarios Handle API management, decentralized data management, and observability Who This Book Is For Developers and DevOps engineers responsible for implementing applications around a microservices architecture, and architects and analysts who are designing such systems

USE THE ACTOR MODEL TO BUILD SIMPLER SYSTEMS WITH BETTER PERFORMANCE AND SCALABILITY Enterprise software development has been much more difficult and failure-prone than it needs to be. Now, veteran software engineer and author Vaughn Vernon offers an easier and more rewarding method to succeeding with Actor model. Reactive Messaging Patterns with the Actor Model shows how the reactive enterprise approach, Actor model, Scala, and Akka can help you overcome previous limits of performance and scalability, and skillfully address even the most challenging non-functional requirements. Reflecting his own cutting-edge work, Vernon shows architects and developers how to translate the longtime promises of Actor model into practical reality. First, he introduces the tenets of reactive software, and shows how the message-driven Actor model addresses all of them–making it possible to build systems that are more responsive, resilient, and elastic. Next, he presents a practical Scala bootstrap tutorial, a thorough introduction to Akka and Akka Cluster, and a full chapter on maximizing performance and scalability with Scala and Akka. Building on this foundation, you’ll learn to apply enterprise application and integration patterns to establish message channels and endpoints; efficiently construct, route, and transform messages; and build robust systems that are simpler and far more successful. Coverage Includes How reactive architecture replaces complexity with simplicity throughout the core, middle, and edges The characteristics of actors and actor systems, and how Akka makes them more powerful Building systems that perform at scale on one or many computing nodes Establishing channel mechanisms, and choosing appropriate channels for each application and integration challenge Constructing messages to clearly convey a sender’s intent in communicating with a receiver Implementing a Process Manager for your Domain-Driven Designs Decoupling a message’s source and destination, and integrating appropriate business logic into its router Understanding the transformations a message may experience in applications and integrations Implementing persistent actors using Event Sourcing and reactive views using CQRS Find unique online training on Domain-Driven Design, Scala, Akka, and other software craftsmanship topics using the for{comprehension} website at forcomprehension.com.
