Azure for Architects - Third Edition

By: Ritesh Modi, Jack Lee, Rithin Skaria

Overview of this book

Thanks to its support for high availability, scalability, security, performance, and disaster recovery, Azure has been widely adopted to create and deploy different types of application with ease. Updated for the latest developments, this third edition of Azure for Architects helps you get to grips with the core concepts of designing serverless architecture, including containers, Kubernetes deployments, and big data solutions. You'll learn how to architect solutions such as serverless functions, you'll discover deployment patterns for containers and Kubernetes, and you'll explore large-scale big data processing using Spark and Databricks. As you advance, you'll implement DevOps using Azure DevOps, work with intelligent solutions using Azure Cognitive Services, and integrate security, high availability, and scalability into each solution. Finally, you'll delve into Azure security concepts such as OAuth, OpenConnect, and managed identities. By the end of this book, you'll have gained the confidence to design intelligent Azure solutions based on containers and serverless functions.

Safeguarding the Cognitive Services key

There are multiple ways to safeguard the exposure of keys to other actors. This can be done using the API Management resource in Azure. It can also be done using Azure Functions Proxies.

Using Azure Functions Proxies

Azure Functions Proxies can refer to any URL, whether internal or external. When a request reaches Azure Functions Proxies, it will use the URL of the cognitive service along with the key to invoke the cognitive endpoint, and it will also override the request parameters and add the incoming image URL and append it to the cognitive endpoint URL as POST data. When a response comes back from the service, it will override the response, remove the headers, and pass JSON data back to the user.
