Linux Distributions on Azure

Linux comes in various flavors, known as distributions or distros, each tailored to specific needs and preferences. When choosing a Linux distribution on Azure, factors like performance, security, and application compatibility come into play. Here are some popular Linux distributions commonly used on Azure:

Deploying Linux on Azure

Now that we’ve explored some Linux distributions, let’s discuss the general process of deploying a Linux virtual machine on Azure:

1. Azure Portal:

2. Azure CLI:

Use the Azure Command-Line Interface (CLI) to deploy a virtual machine. For example, to create an Ubuntu VM:

az vm create --resource-group MyResourceGroup --name MyVM --image UbuntuLTS --admin-username azureuser --ssh-key-value ~/.ssh/id_rsa.pub

3. Azure Marketplace:

Explore the Azure Marketplace for pre-configured solutions based on your chosen Linux distribution. This can include applications, databases, and development environments.

Benefits of Linux on Azure
