Overview of this book

Over the years, Azure cloud services have grown quickly, and the number of organizations adopting Azure for their cloud services is also gradually increasing. Leading industry giants are finding that Azure fulfills their extensive cloud requirements. Azure for Architects – Second Edition starts with an extensive introduction to major designing and architectural aspects available with Azure. These design patterns focus on different aspects of the cloud, such as high availability, security, and scalability. Gradually, we move on to other aspects, such as ARM template modular design and deployments. This is the age of microservices and serverless is the preferred implementation mechanism for them. This book covers the entire serverless stack available in Azure including Azure Event Grid, Azure Functions, and Azure Logic Apps. New and advance features like durable functions are discussed at length. A complete integration solution using these serverless technologies is also part of the book. A complete chapter discusses all possible options related to containers in Azure including Azure Kubernetes services, Azure Container Instances and Registry, and Web App for Containers. Data management and integration is an integral part of this book that discusses options for implementing OLTP solutions using Azure SQL, Big Data solutions using Azure Data factory and Data Lake Storage, eventing solutions using stream analytics, and Event Hubs. This book will provide insights into Azure governance features such as tagging, RBAC, cost management, and policies. By the end of this book, you will be able to develop a full-?edged Azure cloud solution that is Enterprise class and future-ready.

Azure Event Grid

Azure Event Grid is a relatively new service. It has also been referred to as a serverless eventing platform. It helps with the creation of applications based on events (also known as event-driven design). It is important to understand what events are and how we dealt with them prior to Event Grid. An event is something that happened—an activity that changed the state of a subject. When a subject undergoes a change in its state, it generally raises an event.

Events typically follow the publish/subscribe pattern (also popularly known as the pub/sub pattern), in which a subject raises an event due to its state change, and that event can then be subscribed to by multiple interested parties, also known as subscribers. The job of the event is to notify the subscribers of such changes and also provide them with data as part of its context. The subscribers can...
