Overview of this book

Microsoft Azure is currently one of the fastest growing public cloud service providers thanks to its sophisticated set of services for building fault-tolerant and scalable cloud-based applications. This second edition of Azure for Developers will take you on a journey through the various PaaS services available in Azure, including Azure App Service, Azure Functions, and Azure SQL Databases, showing you how to build a complete and reliable system with ease. Throughout the book, you’ll discover ways to enhance your skills when building cloud-based solutions leveraging different SQL/NoSQL databases, serverless and messaging components, containerized solutions, and even search engines such as Azure Cognitive Search. That’s not all!! The book also covers more advanced scenarios such as scalability best practices, serving static content with Azure CDN, and distributing loads with Azure Traffic Manager, Azure Application Gateway, and Azure Front Door. By the end of this Azure book, you’ll be able to build modern applications on the Azure cloud using the most popular and promising technologies to make your solutions reliable, stable, and efficient.

Container groups as the main unit of work

When running containers in Container Instances, you always have two options:

  • Run a single container for one job.
  • Deploy a group of containers, which are specialized in more complex tasks and allow you to partition your work.

The group of containers in Container Instances is called a container group. You may think about it as a single unit of work – all the containers in a group share CPU, memory, network, and storage. They work as a single unit and are destroyed in the same moment as each other. There are two ways to deploy a container group:

  • Deploy your IaC (using, for example, Azure Resource Manager templates or Bicep files) and include a container group there.
  • Use a YAML file that contains the definition of your container group.

In this chapter, we will focus on using YAML as this is a more concise and native way of deploying containers (which, in fact, is very similar to Kubernetes deployments...
