Know the fundamentals of creating and deploying microservices using .NET 6 and gain insight from prescriptive guidance in this book on the when and why to incorporate them. The microservices architecture is a way of distributing process workloads to independent applications. This distribution allows for the independent applications to scale and evolve separately. It also enables developers to dismantle large applications into smaller, easier-to-maintain, scalable parts. While the return is valuable and the concept straightforward, applying it to an application is far more complicated. Where do you start? How do you find the optimal dividing point for your app, and strategically, how should your app be parceled out into separate services? Pro Microservices in .NET 6 will introduce you to all that and more. The authors get you started with an overview of microservices, .NET 6, event storming, and domain-driven design. You will use that foundational information to build a reference application throughout the book. From there, you will create your first microservice using .NET 6 that you can deploy into Docker and Azure Kubernetes Service. You will also learn about communication styles, decentralizing data, and testing microservices. Finally, you will learn about logging, metrics, tracing, and use that information for debugging. What You Will Learn Build a foundation of basic microservices architecture design Follow an example of using event storming and domain-driven design to understand the monolithic application modified for microservices Understand, via detailed commands, how Docker is used to containerize applications Get an overview of creating microservices from a monolithic application Call microservices using RPC and messaging communication styles with MassTransit Comprehend decentralizing data and handling distributed transactions Use Azure Kubernetes Service to host and scale your microservices Know the methods to make your microservices more robust Discover testing techniques for RPC and messaging communication styles Apply the applications you build for actual use Practice cross-cutting concerns such as logging, metrics, and tracing Who This Book Is For Developers and software architects. Readers should have basic familiarity with Visual Studio and experience with .NET, ASP.NET Core, and C#.

Infrastructure as Code (IaC) is gaining popularity and developers today are deploying their application environments through IaC tools to the cloud. However, it can become extremely difficult and time-consuming to manage the state of the infrastructure that has been deployed. This book will provide a complete walkthrough of deploying a SpringBoot application on AWS with multiple environments like production, staging and development. Everything is orchestrated through GitHub Actions and executed through Terraform Cloud to monitor changes in your infrastructure and manage its state. You'll start by reviewing how your infrastructure can be stored in code by spinning up an EC2 server first through the console, then AWS CLI and then using Terraform. You'll then be presented with a practical scenario of setting up a simple EC2 server in a multi-environment (production, staging and development) using GitHub Actions and Terraform Cloud. In the advanced section that follows, this simple EC2 server is expanded into an application that is deployed on an AWS EKS (Elastic Kubernetes Service) using AWS RDS (Relational Database Service) exposed through an AWS ALB (Application Load Balancer) protected using AWS ACM (AWS Certificate Manager), and accessible by setting the AWS Route53. The book then builds up on this infrastructure and demonstrates how it can be deployed in a multi-environment scenario by implementing accounts through AWS organizations. You'll see how to put in restrictions through Service Control Policies, how to protect secrets using AWS Secrets Manager, and how to work with least privileges using IRSA (IAM Roles for Service Accounts). Finally, you'll make the infrastructure more observable using Graphana, Prometheus, and AWS OpenSearch, run security tools, host Route53 zones dynamically based on environments, and implement CloudWatch Alarms for various use cases.
