VaultBook Study Library

Hands-on Azure labs

Twelve labs that build real skill rather than clicking through a tutorial, a searchable command library grouped by what you are actually trying to do, and the cost discipline that stops a practice environment turning into a bill. Track what you have built, tear it down properly, and keep your own notes. Everything stays on your device.

The labs

Twelve labs ordered so each one depends on the last. Every lab states what you will actually learn, the steps in order, the mistake most people make, and roughly what it costs to leave running. Tick them off as you go and the tracker remembers.

Cloud platforms change. Service names, portal layouts, default SKUs, and free tier limits all move, and command flags are occasionally renamed. Every lab here is written around the concept rather than a screenshot, but check the current official documentation for exact syntax and current pricing before you run anything that costs money.

Command library

Grouped by what you are trying to do rather than by service, because that is how you actually reach for a command. Each entry says what it does and the thing worth knowing about it. Placeholders in angle brackets are yours to replace.

Two habits worth forming early. Use a table output format when you are reading and a JSON format when you are scripting, because the default is verbose and hard to scan. And set a default resource group and location in your configuration so you stop typing them on every command, which removes a whole class of typing errors.

Cost control

The part every tutorial leaves out, and the reason most people abandon cloud practice. A lab environment is cheap while you understand what is billing and expensive the moment you stop paying attention. Read this once before your first lab.

This counts what is left running, not currency. Pricing varies by region, SKU, and agreement, so use the official pricing calculator for figures. The point of this tool is to make you notice how many things are still on.

Teardown

The discipline that separates people who learn cloud from people who get a bill and quit. Work through this at the end of every session. It takes two minutes and it is the highest value habit on this page.

The single most common and most expensive mistake in cloud practice is confusing stopping a virtual machine with deallocating it. A stopped machine that still holds its allocation continues to bill for the compute reservation. Deallocating releases it. If you take one thing from this page, take that distinction and check it every time.

Troubleshooting

Eight failure patterns that account for most of the time people lose, each with the diagnostic order that finds the cause fastest. Method rather than answers, because the specific error messages change and the reasoning does not.

The general rule underneath all eight. Work outward from the smallest thing you can verify. Confirm your identity, then your subscription context, then the resource exists, then the network path to it, then the permission on it, then the configuration inside it. Almost every cloud failure is one of those six, and checking them in that order costs less than guessing.

Patterns

Seven architectural shapes that keep reappearing regardless of which services are current. Learning the shape means you can read a design you have never seen before and recognise what it is doing.
