Cloud Game Server Hidden Costs: AWS, Google Cloud, Azure, Oracle

The hidden costs of running a game server on a cloud like AWS, Google Cloud or Azure are outbound data (egress), public IP addresses, disk storage that bills even when the server is stopped, snapshots for backups, and the time you spend managing it. The compute price on the calculator is usually the smallest surprise. Free tiers help, but they come with limits on CPU type, idle servers and data that catch many game server owners out.

Here is each line that shows up on a real cloud bill for a game server, and how to estimate it before it arrives.

Why cloud bills surprise game server owners

Cloud providers price for businesses running websites and apps. A game server behaves differently: it sends a steady stream of packets to every connected player for hours, it needs a public address that friends can remember, and it keeps a world on disk that must survive restarts. Each of those is a separate meter.

Data egress

What it is: a charge per GB of data the server sends out to the internet. Data coming in is usually free. Game servers send far more than they receive, because every player needs constant world updates.

How to estimate:

GB per month = KB/s per player x players x hours played x 3600 / 1,000,000

Use a measured rate for your game. On your own PC, watch the server process in Windows Resource Monitor (Network tab) during a session, divide by the number of players, and you have a real per player number. Our guide on how much bandwidth a game server uses shows how to measure it.

The catch: most clouds include a small monthly egress allowance, then charge per GB. A busy community server can go past that allowance, and egress is billed after the fact, so a popular weekend shows up on next month's bill.

Public IP addresses

Your friends need a stable address to join. Clouds handle this as:

• An ephemeral IP that changes every time the instance stops and starts. Free or cheap, but annoying.
• A static or elastic IP that stays the same. AWS began charging for every public IPv4 address in 2024, including ones attached to running instances, and other clouds charge for reserved addresses too.

Small per hour charges add up over 730 hours a month.

Disk storage

The instance stops, but the disk does not. You keep paying per GB of storage for the volume your world lives on, every hour of the month, whether the server is on or off. Game server installs are larger than people expect: ARK: Survival Ascended, DayZ and 7 Days to Die installs run to tens of GB before any mods.

Snapshots and backups

Backing up a cloud server usually means disk snapshots, billed per GB stored. Keep a week of daily snapshots of a large disk and that is its own line on the bill. Skip them and one bad update or corrupted save loses the world. See how to back up a game server for lighter options, like zipping only the save folder.

Instance type traps

• Burstable instances. Cheap small instances often run on CPU credits. A game server uses CPU steadily, burns the credits, and then gets throttled to a fraction of a core, which shows up as rubber banding.
• ARM instances. ARM machines are cheaper per core, but many game servers, especially those installed through SteamCMD, only ship x86 Linux or Windows builds. Running them on ARM needs an emulation layer and is often slow or broken.
• Windows licensing. Some dedicated servers only run on Windows. Windows instances cost more per hour than Linux ones.

Free tier catches

Free tiers are great for learning, but read the rules:

• Time limits. Some free tiers last 12 months, then bill at normal rates.
• Small instances. Free instances are often 1 GB of RAM or less, too small for most modern game servers.
• Idle reclaiming. Oracle Cloud's Always Free tier is popular for Minecraft because of its generous ARM instances, but Oracle says it may reclaim Always Free compute instances it considers idle. A server nobody plays on for a week can count.
• Capacity. Popular free instance types are often unavailable in busy regions.

Check each provider's own pricing page: AWS, Google Cloud, Azure and Oracle Cloud.

The cost nobody bills you for: time

A cloud VM is a blank machine. You install the game with SteamCMD, open firewall ports in the cloud's security group and in the OS, write a service file so it restarts after crashes, schedule updates and backups, and keep the OS patched. For a technical person that is an evening to set up and some time each month. For everyone else it is the reason the server stops working after the first game patch.

A sample bill checklist

Before you launch, add up:

1. Compute: hourly rate x hours you expect it to run.
2. Disk: GB x storage rate x 730 hours (it never stops).
3. IP: hourly IP rate x 730.
4. Egress: estimated GB over the free allowance x per GB rate.
5. Snapshots: GB kept x snapshot rate.
6. Your time: hours per month x what an hour is worth to you.

Compare the total to a managed plan of the same RAM. Our guide on hourly vs monthly billing has the break even method.

When the cloud is the right call

If you already work with cloud infrastructure, want to automate start and stop around game nights, or need a region managed hosts do not serve, the cloud is a fine choice. Set a budget alert in the billing console on day one so a surprise never gets large.

The flat price option

A managed game server has one line on the bill. On GamezServers you pay for RAM, about 2.50 USD per GB a month, and the server's own address, one click backups, DDoS protection and 24/7 email support are inside that price, with no separate lines for IPs or snapshots. The server is installed for you, every setting from the game's template is in the control panel, and there is nothing to patch. See the games page or the rent a game server page.

FAQ

Is AWS good for hosting a game server?

It works well technically, but the bill has more parts than a game host's: compute, storage, IP and egress. It suits people who already know AWS.

Can I host a Minecraft server on Oracle's free tier?

Many people do, on the ARM instances. Java Minecraft runs on ARM. Watch the idle reclaiming policy and keep your own backups.

Why did my cloud bill go up when nobody played?

Disk storage and reserved IPs keep billing while the instance is stopped. Snapshots also add up over time.

How do I stop surprise cloud charges?

Set a budget alert in the billing console, delete unused disks and snapshots, and release IPs you no longer need.
