The Real Cost of Cloud for Small Business

A New Orleans digital agency signed up for AWS with a $200/month budget. They were spending $600/month by month three. Nobody told them that data transfer, managed databases, and CDN charges would dwarf their compute costs.

This isn't unusual. Cloud vendors have complicated pricing. Small businesses pay the learning tax.

This article tells you what you'll actually pay and why.

What "the cloud" actually costs

Cloud providers charge for:

Compute: Per hour or per second of CPU time. Varies by instance type from $0.005/hour (tiny burstable) to $10+/hour (large GPU instances).

Storage: Per GB per month. $0.023/GB/month for S3 standard. $0.10-0.30/GB/month for managed databases including storage.

Data transfer:

• Inbound: Usually free
• Outbound to internet: $0.09/GB (AWS), $0.087/GB (Azure), $0.12/GB (GCP)
• Cross-region: $0.02-0.08/GB depending on regions

Managed services:

• RDS (managed PostgreSQL): $15-200+/month depending on size
• ElastiCache (managed Redis): $15-500+/month
• CloudWatch (monitoring): $0-50+/month depending on logs and metrics

Support (if you need it):

• Basic: Free (AWS) or $29-100/month
• Developer: $29-100/month
• Business: 10% of monthly AWS spend (minimum $100)
• Enterprise: $15,000+/year

Real cost examples (2025-2026)

WordPress site (5,000 visits/month, managed hosting vs. AWS):

• Managed WordPress (Kinsta): $30-60/month, all-inclusive
• AWS EC2 + RDS: $50-150/month (compute + database + storage + backup + CDN separate)

Small web app (50-100 users, AWS):

• EC2 instance (t3.medium): $30-50/month
• RDS PostgreSQL (db.t3.micro): $15-30/month
• Data transfer: $10-50/month depending on traffic
• ECR (container registry): $5-10/month
• ALB (load balancer): $16-25/month
• Total: $75-165/month, not including monitoring or backups

Medium web app (500 users, AWS):

• EC2 instances (2x t3.large for redundancy): $120-150/month
• RDS PostgreSQL (db.m5.large): $120-200/month
• Data transfer and CDN: $100-300/month
• ElastiCache: $50-100/month
• Load balancer + monitoring: $50-75/month
• Total: $440-825/month

E-commerce site (Shopify vs. self-hosted WooCommerce on cloud):

• Shopify Basic: $29/month + 2% transaction fees
• Shopify Standard: $79/month + 1% transaction fees
• WooCommerce on AWS Lightsail: $20-60/month + payment processing fees
• WooCommerce on managed VPS: $30-80/month + payment processing fees

Why cloud costs surprise small businesses

"We only use a small instance." The instance is one line item. Data transfer, managed services, and storage add 30-100% on top.

"We're only running a small database." Managed databases include compute, storage, backups, and maintenance. They're convenient but cost 3-5x more than running PostgreSQL on a raw VPS.

"We don't use much data." Even small sites transfer data. User uploads, image serving, API responses—all count toward egress.

"We don't need premium support." Until you have a production outage on a Saturday night. Then you wish you had someone to call.

Price increases happen. AWS raised prices 17 times between 2021 and 2024. GCP and Azure have raised prices too. Your $100/month bill last year might be $130/month this year for the same workload.

How to reduce cloud costs

Right-size your instances. Most SMB cloud deployments are over-provisioned. A t3.large running a low-traffic app is money wasted. Use cloud monitoring to find your actual CPU and memory utilization.

Use reserved instances or savings plans for stable workloads. If your baseline usage is predictable, commit to 1-3 years and save 30-60%. This requires estimation and commitment.

Move static assets to a CDN. Serving images and files from CloudFront costs less than serving them from EC2. It also reduces your compute load.

Clean up after yourself. Old snapshots, unused EBS volumes, orphaned resources—these all bill. Audit your environment quarterly.

Consider managed hosting instead of raw cloud. If you just need WordPress or a standard application, managed hosting is often cheaper than DIY cloud infrastructure.

Vendor questions (copy/paste)

• For a workload of [X users, Y GB storage, Z GB/month transfer], what's the realistic monthly cost including all services?
• Have you raised prices in the last 24 months? By how much?
• What does it cost to run this workload for 12 months? 24 months?
• What managed services are required for a production deployment that aren't obvious from the compute pricing?
• What happens to my costs if usage grows 50%?

Minimum viable implementation

1. Use the pricing calculator with realistic usage estimates, not optimistic ones.
2. Add 40% to your estimate for storage, data transfer, and managed services.
3. Set billing alerts at 50%, 75%, and 100% of expected spend.
4. Review your first three bills line by line. Every line item. Understand what each charges for.
5. Schedule a quarterly cost review. Cloud costs drift. Regular audits catch waste.

When to hire help

• Your cloud bill is consistently higher than your estimate with no clear explanation.
• You don't have anyone on staff who reads cloud billing dashboards.
• You had a surprise bill (>$500 over estimate) and want to understand what happened.
• You've been on the cloud for over a year without a cost optimization review.
• You're planning to migrate to the cloud and want an accurate budget before committing.

A cloud cost optimization engagement typically takes 2-8 hours and costs $500-2,500. The savings usually pay for the engagement within 60-90 days.
