In this module, you'll delve into deploying the Todo application to a scalable Azure Red Hat OpenShift cluster. Upon completion, you'll have successfully established an Azure Database for PostgreSQL server and a fully functional Todo application developed in Quarkus and deployed in a cloud-native environment.

Explore the underlying technologies in more detail here:

Azure Red Hat OpenShift

Azure Red Hat OpenShift (ARO) is a fully managed Kubernetes platform as a service (PaaS) that combines the power of Red Hat OpenShift with the scale and reliability of Microsoft Azure. It provides a comprehensive environment for building, deploying, and managing containerized applications.

Key features and benefits of Azure Red Hat OpenShift include:

  • Fully managed: Microsoft and Red Hat jointly manage the infrastructure, control plane, and application nodes, reducing operational overhead for customers.
  • Enterprise-grade: Built on a stable and secure foundation, Azure Red Hat OpenShift offers enterprise-grade features like high availability, disaster recovery, and security.  
  • Hybrid flexibility: Deploy OpenShift clusters on-premises or in the cloud using Azure Red Hat OpenShift Dedicated or Azure Red Hat OpenShift, respectively.  
  • Developer-friendly: Provides a rich set of tools and features to simplify application development, deployment, and management.  
  • Integrated ecosystem: Benefits from a vast ecosystem of tools, technologies, and partners, enabling seamless integration with existing applications and infrastructure.

Azure Database for PostgreSQL

Azure Database for PostgreSQL is a fully managed relational database service offered by Microsoft Azure. It provides a highly available, scalable, and secure PostgreSQL environment that is ideal for a wide range of applications.

Key features and benefits include:

  • Fully managed: Microsoft handles the infrastructure, maintenance, and updates, allowing you to focus on your application.
  • High availability: Built-in redundancy and automatic failover ensure your database remains accessible. Scalability: Easily scale your database up or down to meet changing demands.
  • Security: Robust security features, including encryption, authentication, and authorization, protect your data.
  • Compatibility: Compatible with the open-source PostgreSQL ecosystem, enabling you to leverage existing tools and skills.
  • Integration: Seamless integration with other Azure services, such as Azure Functions, Logic Apps, and Azure Data Factory.

Azure CLI

Azure CLI is a powerful command-line interface (CLI) tool that allows you to manage and interact with Azure resources directly from your terminal. It provides a flexible and efficient way to automate tasks, create and configure resources, and execute complex operations within the Azure cloud platform.

For example, to get the details of a subscription, you can use the following command:

az account show

In this module, you use the Azure CLI to spin up the Azure Red Hat Openshift cluster. Access the Azure CLI from a terminal or through Visual Studio Code. Or you can access it from Azure Cloud Shell. This browser-based shell experience is hosted in the cloud. In Cloud Shell, the Azure CLI is configured for use with your Azure subscription.
