Day 01 — Azure CLI Basics

Welcome to Day 1 of my 90-day cloud engineering challenge! I'm documenting everything I learn as I go — partly to hold myself accountable, and partly because writing things down helps them actually stick.

Today's focus: getting comfortable with the Azure CLI and creating my first resource entirely from the terminal.

What I Learned
The Azure CLI is a command-line tool that lets you manage Azure resources directly from your terminal, without needing to click through the Azure Portal. Once it's installed and you're logged in, you can create, update, and delete resources with simple commands — which is faster and more repeatable than navigating a UI.

Commands I Ran

1. Install CLI: For me i am on window so i am using below command

winget install --id Microsoft.AzureCLI

1. Check the installed version

az --version

This confirmed the CLI was installed correctly and showed me the version, dependencies, and Python environment it's running on. Good first sanity check before doing anything else.

1. Log in to Azure

az login
az account show

This opens a browser-based login flow and connects the CLI to my Azure account. Once logged in,

1. Create my first Resource Group

az group create --name taiwo-devops-rg --location eastus

Output:

{
  "id": "/subscriptions/<subscription-id>/resourceGroups/taiwo-devops-rg",
  "location": "eastus",
  "managedBy": null,
  "name": "taiwo-devops-rg",
  "properties": {
    "provisioningState": "Succeeded"
  },
  "tags": null,
  "type": "Microsoft.Resources/resourceGroups"
}

A Resource Group is basically a container that holds related Azure resources — useful for organizing and managing things together (and for cleaning everything up at once later by just deleting the group).

What This Taught Me
This exercise taught me how to create a resource group and control exactly where it lives (in this case, eastus). More importantly, it showed me how much faster the CLI can be compared to the Azure Portal — no waiting on pages to load, no risk of losing your place if your internet connection hiccups. Just a clean command and a clean output. I can already see why CLI/scripting skills matter so much in DevOps and cloud engineering.

Problems I Faced
Honestly, the biggest challenge today was just remembering the command syntax — this is my first real session using the Azure CLI, so nothing is muscle memory yet. But I expect that to improve quickly with repetition. The more I run these commands, the more naturally they'll come.

What's Next
This is Day 1 of 90. Tomorrow I'll be building on this foundation — likely exploring more az commands and starting to provision some actual resources inside this resource group.

Follow along with the rest of the series as I document 90 days of hands-on cloud engineering learning.
