Alright, let's settle this. Everyone gets hypnotized by compute and storage pricing, but the real bloodbath is in the networking add-ons that quietly siphon your budget. I decided to actually run the numbers on NAT Gateways—because apparently just letting your VMs talk to the internet is a luxury good now.
I built a model for a "modest but real" workload: about 2 TB of data processed outbound per month, broken into a mix of steady background traffic and occasional spikes. The usual suspects: AWS, GCP, Azure. I ignored the base compute and just looked at the NAT tax.
The headline? If your outbound traffic is under, say, 5 TB a month, Azure's **Basic SKU** runs away with it. It's not even close. Here's the carnage for my 2 TB scenario:
* **Azure (Basic)**: ~$32/month. Flat rate of $0.045/hour ($32.40) plus a laughable $0.04/GB for data processing. The data cost is negligible here; it's all about the hourly.
* **GCP**: ~$48/month. Their "first 5 GB free" is a cute joke. $0.0475/GB after that adds up fast.
* **AWS**: ~$74/month. The most expensive by a mile for this volume. $0.045/hour (same as Azure!) **plus** $0.045/GB. You're paying the hourly *and* a hefty data premium. Ouch.
The pivot point is around sustained high throughput. AWS becomes "competitive" (if you can call it that) only when you're pushing enough data that the hourly fee becomes a rounding error. For probably 80% of the dev teams and startups I talk to, that's not reality. We're not all Netflix.
The real kicker? Azure's **Basic** SKU has a 16-outbound-IP limit and a 5 Gbps ceiling. That's the catch. If you need more, you jump to the **Standard** SKU, and the pricing model flips—now it's $0.075/hour plus $0.04/GB, and you're suddenly in a different, more expensive ballpark. But for a ton of middle-tier apps, those Basic limits are *fine*. AWS and GCP don't give you that "budget-conscious" tier; it's their way or the highway.
So the next time someone parrots "AWS is the price leader," ask them to show their NAT Gateway bill. Azure is playing a clever game here, offering a genuinely lower-cost tier for the volume most of us actually operate at, while hoping you won't notice the SKU jump later. For once, the underdog wins a round on pure, cynical pricing math.
Has anyone else done a deep dive on the crossover points? Or found other networking services where one provider is shockingly out of step? I'm looking at you, Load Balancer pricing...
