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.

Understanding Cognitive Services

Azure Cognitive Services consists of HTTP endpoints that accept requests and send responses back to the caller. Almost all requests are HTTP POST requests and consist of both a header and a body.

The provisioning of Cognitive Services generates two important artifacts that help a caller invoke an endpoint successfully. It generates an endpoint URL and a unique key.

The format of the URL is https://{azure location}.api.cognitive.microsoft.com/{cognitive type}/{version}/{sub type of service}?{query parameters}. An example URL is:

https://eastus.api.cognitive.microsoft.com/vision/v2.0/ocr?language=en&detectOrientation=true

Cognitive Service is provisioned in the East US Azure region. The type of service is computer vision using version 2 and the subtype is OCR. There are generally a few subtypes for each top-level category. Lastly, there are a few query string parameters, such as language and detectOrientation. These query parameters are...
