Preface
There are different hosting models available in the cloud. In the case of Infrastructure as a Service, you reserve a Virtual Machine along with necessary infrastructure services like Virtual Networks, Data Disks, IP Address, and many more. And then, you host your application on the Virtual Machine. You end up paying for the Virtual Machine and all necessary infrastructure for as long as you are using it. You also end up managing the software upgrades and patches for the Virtual Machine. The cloud vendor manages the underlying infrastructure.
You may choose to host your application as Platform as a Service Model where you delegate the responsibility of infrastructure and the hosting software management to the cloud vendor. You build your application and host it on the cloud service and need not worry about the underlying infrastructure and the hosting software. You need to plan out all scaling requirements and configure scaling for your application. This hosting model is a cheaper option as compared to infrastructure as a Service. However, you end up paying for the service that is hosting your application even if it is idle and not serving any request.
You can use the Serverless hosting model to host your application. The Serverless hosting model does not mean that your application is not executing on any server. Here the cloud vendor takes care of the underlying infrastructure and the hosting software. The underlying cloud platform decides when and how to scale your hosted application. You get billed only for the duration when the code executes and the computing resources your application consumes while executing. You end up paying for what you use, unlike other hosting models. These aspects make Serverless Computing the popular choice for hosting applications.
Microsoft Azure offers an array of Azure Serverless Services. You can build and host enterprise-grade highly scalable Serverless solutions using the Azure Serverless offerings. You can host your business logic, build business workflows, build event-driven solutions, and many more using Azure Serverless offerings. You can integrate your Serverless solutions with other Azure Services and on-premises applications with ease using Azure Serverless services. You can also define an enterprise-grade messaging strategy for your Azure Serverless components. This book explains each of these areas in detail.
The book starts with basic concepts of Serverless Computing, its evolution, characteristics, and benefits. You will get a thousand feet overview of Azure Serverless Computing offerings here along with a basic understanding of Azure Serverless Computing Fundamentals.
The next set of chapters is based on the Function as a Service (FaaS) programming model on the Azure platform. In these chapters, you will gain proficiency in creating Azure Function, which is the basic unit of Azure Serverless Computing. You will learn how to orchestrate Azure Functions using Durable Function and manage the state of these Azure Functions.
The next set of chapters deal with building Azure Serverless Messaging, Integration, and Workflow solutions that facilitate communication between different components in the Azure Serverless ecosystem. Azure Logic Apps, Azure Event Grid, and Azure Service Bus are explained in detail in these chapters. The subsequent chapters deal with Azure Serverless advanced areas like Azure Serverless Database and Azure Serverless Kubernetes. These new Serverless offerings are very much essential to build highly scalable next-generation Serverless solutions.
By now, you will gain a good amount of proficiency in Azure Serverless services. You get a good understanding of the integration and messaging strategy for the Azure Serverless services. The next set of chapters focuses on building and implementing a near-production Azure Serverless solution. You learn how to design and build Azure Serverless solutions using all the concepts you learned in this book.
