Notes from real projects. What worked, what did not, and what I would do differently next time.
Azure API Management puts a gateway in front of your APIs for throttling, auth, and versioning, but it's not worth the overhead for every API you run.
Availability zones protect you from a single datacenter failing, not from a whole region going down. Here's what they actually do and when the extra setup is worth it.
Traffic Manager and Load Balancer sound like they do the same thing. They don't. One works at the DNS level across regions, the other spreads traffic inside one region. Here's what each is actually for.
Azure Front Door routes visitors to the closest healthy copy of your site and can add a free SSL certificate along the way. Here's when it actually earns its keep.
Azure managed identities let an App Service, Function App, or VM authenticate to other Azure resources without you ever having to store or rotate a secret.
Application Insights sounds like another thing to configure, but once you turn it on for a web app, you stop guessing why it's slow or crashing.
A storage account isn't one service, it's a container for blob storage, file shares, queues, and tables that all share the same name and access keys. Here's what each piece does and when you'd actually reach for one.
Windows Hello, security keys, and the Authenticator app are all called passwordless, but they solve different problems. Here's how to pick the right one and roll it out without locking anyone out.
Azure Static Web Apps is a good fit for a narrower set of sites than the name suggests. Here's where it actually saves money and where it doesn't.
If you're picking between Azure App Service and Container Apps for a new deployment, here's what actually separates them once you get past the pitch.
If you've got more than one VM doing the same job, at some point you'll bump into Azure Load Balancer. Here's what it actually does and when it's worth setting one up.
Azure Virtual Desktop isn't a replacement for OneDrive or a normal laptop. Here's what it's actually for, and when it's not worth the setup.
A quick, practical rundown of the choices that actually matter when you create your first Azure VMs: sizing, disks, and networking, without the jargon.
If you've ever opened port 3389 on a VM just to get in for five minutes, Azure Bastion is built to make that unnecessary. Here's what it actually does and when it earns its cost.
If MFA keeps popping up even on a device you use every day, it usually comes down to how Entra ID tracks trust, not a bug. Here's what actually resets it and how to fix it for good.
Azure Monitor alerts are easier to set up than most people think. Here is how to configure your first one without drowning in noise.
Azure Key Vault keeps secrets, keys, and certificates out of your config files and scripts. Here is what it actually stores, why it beats app settings, and how to set one up without overthinking it.
None of these are about lacking technical skill. They're about habits that don't feel important until the moment they suddenly are.
Start with the specific problem you have, set billing protections immediately, and don't skip basic security just because you're small.
A small piece of code that runs when something happens and stops. Here's a real example, from an invoice upload to an automatic email.
Azure Backup handles the scheduled copying for you. Retention is a decision, not a default, and backup is not the same as disaster recovery.
Entra ID is what checks who you are and what you're allowed to access, every time you sign into Microsoft 365, Teams, or Azure.
The surprises mostly come from things left running by accident, not from Azure being inherently expensive. A few habits prevent almost all of it.
App Service costs you flexibility in exchange for saving maintenance work. A VM costs you time in exchange for full control. Most teams don't need that control.
A resource group is a container, not a server. Here's why that organization actually matters once your Azure setup grows past one test project.
Latency is the obvious reason to care about your Azure region. Data residency is the one that catches people out later.
People ask me this more than almost any other question. Here's the plain version, no jargon, no sales pitch.
