Hidden Costs Breakdown

1

Bandwidth Egress Costs

high overage

Azure charges for outbound bandwidth, which can become very expensive for data-intensive workloads. Users report Azure bandwidth pricing is significantly higher than alternatives with unlimited bandwidth options.

reddit

I need to use Azure VM for scraping and downloading several sources (around 100TB). Based on Azure pricing, bandwidth is very expensive. Previously, I used OVH Cloud, which doesn't have any cost for bandwidth (it is unlimited).

2

Unexpected Price Tier Changes and Increases

high addon

Microsoft has a history of raising Azure prices and restructuring pricing tiers in ways that effectively increase costs significantly. Users report mid-contract cost increases and deprecated tiers being replaced with more expensive options.

reddit

Last year Microsoft raised prices of azure and other software by 10%. And this year they changed many pricing tiers in azure in such a way that effective upgrade would cost 30%. They offered lower priced tiers that would never match the real world traffic, and deprecated existing tiers. New tiers would cost you almost double.

3

Inter-Zone Networking Fees

critical overage

For workloads involving data transfer across availability zones (e.g., Kafka clusters, distributed systems), Azure charges per-GB inter-zone bandwidth fees that can dwarf compute costs. A small Kafka cluster with 35MB/s traffic can cost $54,624/year in Azure just for storage, comparable to AWS at ~$70k/year, versus $2,160/year on bare metal.

reddit

In Azure, disks are charged per "tier" and have worse performance - Azure themselves recommend these for development/testing and workloads that are less sensitive to perf variability.

reddit

With 6 brokers though, it would cost us $953 a month per drive just for the storage alone - $68,616 a year for the cluster. (AWS was $70k)

4

Load Testing Cost Surprises

medium overage

Azure Load Testing pricing can be dramatically more expensive than self-hosted alternatives. Users report running equivalent tests for under $1/hour on spot VMs vs. ~$2,000 through Azure Load Testing service.

reddit

I have a scenario that I run with artillery that generate 100k vUsers. I run it on a spot VM with 16 vCPU it cost less than a dollar per hour, I am afraid that if I do the same with Azure it will cost me around 2k$ based on Azure Pricing Calculator.

5

No Spending Limits on Pay-As-You-Go Accounts

high overage

Azure spending limits are only available on certain starter/free accounts and not on pay-as-you-go or commitment plans. This means unexpected usage spikes can result in uncapped bills.

reddit

The spending limit isn't available for subscriptions with commitment plans or with pay-as-you-go pricing.

6

Egregious Bandwidth and Inter-Zone Transfer Costs

critical overage

Azure charges significantly for outbound bandwidth and inter-zone data transfer. Users running data-intensive workloads report that bandwidth costs dwarf compute costs. Azure also charges $0.0005 per 10k disk operations, which adds up for high-throughput workloads.

reddit

Azure and its problem with expensive bandwidth - How reduce cost? I need to use Azure VM for scraping and downloading several sources (around 100TB). Based on Azure pricing, bandwidth is very expensive.

reddit

In Azure, disks are charged per 'tier' and have worse performance... Note that Azure also charges you $0.0005 per 10k operations on a disk.

7

Credit Card Required Even for Free Trial

medium compliance

Azure requires a credit card for both the free trial and pay-as-you-go plans. There is no way to access Azure's free tier allowances without registering a payment method, creating a barrier and billing risk for new users.

reddit

I can't seem to find how to signup for the free tier. All I get is a Free trial that still requires a bank card or the Pay as you go option which also requires a bank card. Am I missing something or there is no way to sign up to Azure's free allowance without a registered method of payment?
