Estimated Monthly Summary
Understanding Azure Pricing and Cost Factors
Calculating the cost of Microsoft Azure can be complex due to the pay-as-you-go nature of cloud computing. This estimator provides a baseline for the most common components: compute, storage, and networking.
1. Compute Instances (Virtual Machines)
Azure VMs are billed per second. The price depends on the number of vCPUs and the amount of RAM. B-Series is ideal for workloads that don't need full CPU performance all the time, while D-Series is the standard for web servers and general enterprise applications. If you are running Windows, a licensing fee is typically added to the hourly rate unless you have Azure Hybrid Benefit.
2. Storage Costs
Azure Managed Disks are priced based on the capacity provisioned. Standard HDD is cost-effective for backups, while Premium SSD is required for production databases and high-I/O applications. Remember that you pay for the provisioned disk size, regardless of how much data is actually written to it.
3. Data Transfer (Bandwidth)
Inbound data transfer (data coming into Azure) is free. However, Outbound Data Transfer (Egress) is billed after the first 5GB per month. This cost can fluctuate based on the region and the amount of traffic your application serves to the internet.
Example Calculation Scenario
If you run one Standard D-Series VM for a full month (730 hours):
- Compute: $0.09/hr x 730 = $65.70
- Storage (128GB SSD): 128 x $0.10 = $12.80
- Data Transfer (50GB): (50 – 5) x $0.08 (approx) = $3.60
- Total Estimated Cost: ~$82.10 per month
How to Optimize Your Azure Spend
- Reserved Instances: Commit to a 1-year or 3-year term to save up to 72% compared to pay-as-you-go pricing.
- Azure Hybrid Benefit: Use your existing on-premises Windows Server or SQL Server licenses to reduce cloud rates.
- Auto-Scaling: Set up rules to shut down non-production VMs during weekends or evening hours to stop the compute meter.
