Container Registry Costs Will Murder Your Budget If You Pick Wrong

Registry pricing is a dumpster fire - you've got storage, transfer, scanning fees, and a bunch of other charges that add up fast. Nobody tells you about the real costs until your credit card gets hit.

Storage Costs: Not As Simple As They Seem

AWS ECR looks straightforward - $0.10 per GB monthly with no base fee. Cool, right? Wrong. You'll hit data transfer costs that make storage look cheap. I've seen teams get a $50 storage bill and a $300 transfer bill in the same month.

Azure Container Registry plays the tiered game. Basic tier gets you 10 GB for $5/month - sounds reasonable until you realize Basic tier is basically useless. Premium tier is $50/month but includes 500 GB and actually works for production. Learned that the hard way when Basic's webhook limits broke our deployments.

Google Artifact Registry gives you 0.5 GB free, then it's $0.10 per GB. The 0.5 GB free is a joke - barely enough for a "hello world" image. Our 500 GB of images costs about $50/month there, which is honest at least.

Data Transfer: The Real Budget Killer

Here's where they get you. AWS data transfer follows their standard egress pricing - $0.09/GB to the internet, plus inter-region costs. We made the mistake of putting ECR in us-east-1 and deploying to eu-west-1. That 2.5GB Docker image costs $0.225 every time it gets pulled. With CI/CD pulling it 40 times daily across regions, that's $270/month just in transfer costs for ONE image.

Google's transfer costs range from $0.01 to $0.08 per GB depending on distance. Sounds cheap until you realize your CI/CD pipeline pulls the same images 50 times a day across regions. That $0.01 becomes real money.

Docker Hub pulled a fast one in 2024. Pricing went up 67% - Pro is now $9/month and Team jumped to $15/user/month. The sticker shock is brutal, especially with stricter rate limiting on free tiers. Had one client's Docker Hub bill go from $200/month to $480/month overnight when they upgraded to avoid rate limiting issues.

The Enterprise Tax

JFrog Artifactory starts at $150/month for Pro and goes to $950/month for Enterprise X. Expensive as hell, but it actually includes everything - scanning, X-ray analysis, distribution. No surprise bills. Sometimes paying more upfront saves money vs nickel-and-diming.

Harbor is free if you don't value your weekends. Self-hosting means you handle backups, updates, security patches, and 3am outages. One guy on the team becomes "the Harbor guy" and hates his life. But it works, and big enterprises save serious cash running it on existing K8s clusters.

Managed vs Self-Hosted: Pick Your Poison

Managed services cost more but someone else deals with backups and upgrades. Self-hosting Harbor is cheaper until things break at 3am and you're debugging networking issues while the CEO asks why deployments are down.

I've run both. Managed services are boring but reliable. Self-hosted saves money but requires ops expertise. Pick based on whether you want predictable bills or predictable 3am wake-up calls.

Registry pricing isn't just storage costs - the hidden fees will murder your budget if you're not careful. Here's what actually matters when you're spending real money.

Security and Scanning Costs (The Sneaky Bastards)

Vulnerability scanning costs extra everywhere, and you can't run production without it. Google Container Scanning charges $0.26 per image scan - sounds cheap at $0.26 until your CI pipeline triggers 47 scans per day. That Node.js app with 3 microservices? Each git push scans 3 images. 15 daily pushes = 45 scans = $11.70/day = $351/month in scanning costs alone. One team I know got a $500 scanning bill for a $50 storage bill.

Azure ACR Premium includes scanning, which is why it costs $50/month vs $5 for Basic. That $45 difference is your security tax. Worth it because security team won't sign off on Basic tier anyway.

Transfer Costs That Scale Like Crazy

Network costs are where they really get you. That 100 GB monthly sounds reasonable until you realize your CI/CD pipeline pulls images across regions constantly. I watched one team's AWS ECR bill go from $20 to $200 when they added a second region. $9 per 100 GB out to internet adds up fast.

Multi-region deployments are a budget killer. You either pay for transfer costs or pay for duplicated storage. Neither is cheap. We ended up with regional registries and still got hit with sync costs.

How Costs Scale (Spoiler: Badly)

JFrog's pricing actually scales well if you hit their tiers. 25 GB base in Pro, then reasonable overage rates. But that $150/month minimum hurts startups. Enterprise contracts are where the real savings happen, but you need serious volume to negotiate.

AWS ECR scales linearly - $0.10 per GB forever. No volume discounts, no enterprise rates (unless you're spending millions). Google and Azure are similar. They make money on predictable per-GB pricing, not enterprise deals.

Regional Placement Games

Registry placement matters for transfer costs. AWS pricing is the same globally for storage, but transfer between regions varies. Putting your registry in us-east-1 and pulling from eu-west-1 costs more than you think.

Smart teams put registries near their compute. Dumb teams (like us initially) put everything in one region and pay transfer costs to everywhere else. Learn from our stupidity.

Harbor: Free Software, Expensive Operations

Harbor is "free" until you calculate the real operational overhead. Running Harbor on AWS with proper HA costs $180/month minimum (2x t3.medium instances, RDS Postgres, ELB). But the hidden costs destroy the math:

• DevOps engineer time: 3 hours/week at $75/hour = $900/month
• Backup and monitoring setup: S3, CloudWatch, alerts
• Security patches: Harbor 2.9.1 had 3 CVEs, someone has to patch it
• 3am outages: Harbor's Redis cache fails, takes registry down, ruins weekend
• Database maintenance: PostgreSQL upgrades, connection tuning, backup verification

The break-even point is around 1TB of storage or when managed service costs get ridiculous. But only if you have someone who doesn't mind being "the Harbor guy" and dealing with YAML hell.

Enterprise Deals (For the Big Spenders)

Large enterprises get 20-50% discounts through volume commitments and multi-year contracts. But you need serious usage to negotiate. If you're spending $10K+/month on registries, you can probably get better rates.

JFrog enterprise deals include support, professional services, and SLAs. Sometimes worth the premium when your container infrastructure is business-critical and downtime costs more than the subscription.

But most startups and smaller companies pay list price and deal with it. The discount tiers are designed for enterprises with budget and leverage.
