Overview of this book

Azure is one of the leading cloud providers in the world, providing numerous services for data hosting and data processing. Most of the companies today are either cloud-native or are migrating to the cloud much faster than ever. This has led to an explosion of data engineering jobs, with aspiring and experienced data engineers trying to outshine each other. Gaining the DP-203: Azure Data Engineer Associate certification is a sure-fire way of showing future employers that you have what it takes to become an Azure Data Engineer. This book will help you prepare for the DP-203 examination in a structured way, covering all the topics specified in the syllabus with detailed explanations and exam tips. The book starts by covering the fundamentals of Azure, and then takes the example of a hypothetical company and walks you through the various stages of building data engineering solutions. Throughout the chapters, you'll learn about the various Azure components involved in building the data systems and will explore them using a wide range of real-world use cases. Finally, you’ll work on sample questions and answers to familiarize yourself with the pattern of the exam. By the end of this Azure book, you'll have gained the confidence you need to pass the DP-203 exam with ease and land your dream job in data engineering.

Handling interruptions

Interruptions to stream processing might occur due to various reasons such as network connectivity issues, background service upgrades, intermittent bugs, and more. Event Hubs and ASA provide options to handle such interruptions natively using the concept of Azure Availability zones. Availability zones are physically isolated locations in Azure that help applications become resilient to local failures and outages. Azure lists the regions that are paired together to form availability zones.

Services that support availability zones deploy their applications to all the locations within the availability zone to improve fault tolerance. Additionally, they ensure that service upgrades are always done one after the other for the availability zone locations. Therefore, they ensure that at no point will all the locations suffer an outage due to service upgrade bugs. Both Event Hubs and ASA support availability zones. Let's look at how to enable this feature for...
