Oracle Cloud Infrastructure (OCI) is basically giving away the farm, and honestly, it’s a bit weird that more people aren't screaming about it. Most "free tiers" from big providers like AWS or Google Cloud give you a tiny, single-core instance with 1 GB of RAM that chokes the moment you try to run a Minecraft server or a basic Docker stack. Oracle went the other way. They offer the Ampere A1 Compute instances. We're talking up to 4 ARM-based CPUs and a massive 24 GB of RAM. For free. Forever.
Getting this Oracle Always Free resources 24 GB RAM server setup guide working isn't always a walk in the park, though. You’ve probably seen the "Out of Capacity" errors or struggled with the complex Virtual Cloud Network (VCN) settings. It's frustrating. But if you play your cards right, you end up with a beast of a VPS that would easily cost you $30 to $50 a month elsewhere.
Why the Ampere A1 is a Game Changer
Let’s talk specs. Most free VMs are x86-based micro-instances. Oracle's Ampere A1 instances use ARM architecture. Specifically, these are Ampere Altra processors. Why does that matter? Because ARM is incredibly efficient.
You get 3,000 OCPU hours and 18,000 GB hours per month for free. In plain English, that means you can run one giant VM with 4 OCPUs and 24 GB of RAM, or you can split it up into four smaller servers. Most people go for the "big boy" setup—one massive 24 GB node. This is enough juice to run a heavy-duty Plex server (though transcoding is tricky on ARM), a massive WordPress site with caching that actually works, or even a localized LLM if you're feeling adventurous.
Navigating the Signup Minefield
The biggest hurdle isn't the technical setup; it's getting past the signup page. Oracle is notoriously picky.

Use a real credit card. Prepaid cards or "virtual" cards from apps usually get flagged and rejected instantly. They do a small temporary hold to verify you're a human, then release it. Also, make sure your address matches your bank statement exactly. If you live on "Main Street" but your bank says "Main St," Oracle’s fraud detection might just kick you to the curb. It's annoying, I know.
Choosing Your Home Region
This is the one choice you can't undo. Your "Home Region" is where your free resources live. If you pick a popular region like US-East (Ashburn) or London, you might run into the dreaded "Out of Capacity" error when trying to create your ARM instance.
Think about it. Everyone wants the free 24 GB server. If the data center is full, you're stuck waiting. Sometimes picking a slightly less "trendy" region—maybe Phoenix instead of Ashburn—gives you a better shot at snagging those Ampere chips.
The Actual Oracle Always Free Resources 24 GB RAM Server Setup Guide
Once you’re in the dashboard, don’t get overwhelmed by the enterprise-grade UI. It looks like a cockpit because OCI is designed for Fortune 500 companies.
- Go to Compute then Instances.
- Click Create Instance.
- Under Image and Shape, click Change Shape.
- Select Ampere as the processor type.
- Check the VM.Standard.A1.Flex box.
- Drag the sliders. You want 4 OCPUs and 24 GB of RAM.
If it says "Always Free Eligible" next to it, you're golden. If it doesn't, you might have selected the wrong processor or exceeded your limits.
Networking: The Part Everyone Messes Up
Oracle’s default security posture is "lock everything down." Your server will be running, but you won't be able to reach it via SSH or HTTP unless you open the gates.
You need to edit your Virtual Cloud Network (VCN). Find the Security List for your public subnet. You’ll need to add "Ingress Rules." For SSH, you need port 22 open. For a web server, you need 80 and 443.
But wait. There’s a catch.
Oracle’s Ubuntu and Oracle Linux images have an internal firewall (iptables or firewalld) running inside the OS itself. Even if you open the ports in the Oracle Cloud dashboard, the OS will still block traffic. You have to SSH in and manually open the ports there too.
Use these commands if you’re on Ubuntu:sudo iptables -I INPUT 6 -p tcp --dport 80 -j ACCEPTsudo iptables -I INPUT 6 -p tcp --dport 443 -j ACCEPTsudo netfilter-persistent save
Handling the "Out of Capacity" Nightmare
You click "Create" and get a red box saying Oracle is out of Ampere A1 nodes. It happens. A lot.
Since these resources are free, they are first-come, first-served. You have three choices. One: wait and try again at 3 AM. Two: use a script. There are several Python and PHP scripts on GitHub (search for "OCI-Instance-Resource-OCID") that use the Oracle API to constantly request an instance every minute until one opens up. People have had success letting these run for a few days until a slot becomes available. Three: upgrade to a "Pay As You Go" account.
Wait! Don't panic.
Upgrading to Pay As You Go doesn't mean you lose your free tier. It just means you get higher priority for resources. As long as you stay within the 4 OCPU / 24 GB RAM limit, your bill will still be $0.00. It’s a "pro tip" for skipping the line. Just be careful not to accidentally spin up a massive x86 database that costs $2 an hour.

Operating System Choices: ARM Compatibility
Since this is an ARM server, not everything built for Windows or standard Linux will run perfectly.
Oracle Linux is the "native" choice. It’s basically RHEL with a few tweaks. It’s stable and well-supported. However, most people prefer Ubuntu. Ubuntu 22.04 or 24.04 works brilliantly on ARM.
Check your software. If you're running Docker, most modern images have arm64 versions. If you're trying to run old, proprietary software that only exists for x86_64, you’re going to have a bad time. You can use emulation like QEMU, but that eats into your performance gains.
Performance Reality Check
Is it actually fast? Yes.
The Ampere Altra cores are surprisingly snappy. In multi-core benchmarks, this free 4-core setup often beats out paid "entry-level" VPS plans from Linode or DigitalOcean. It handles high I/O tasks well, though the free block storage (Boot Volume) is capped at 50 GB by default (you can go up to 200 GB for free total).
The network speed is usually capped at 1 Gbps or 4 Gbps depending on the shape allocation. For a free resource, that’s insanely generous. You could host a private VPN (like WireGuard) and get incredible speeds that put those "free VPN" apps to shame.
Keeping Your Account Alive
Oracle has been known to reclaim "idle" resources. If your 24 GB beast is just sitting there using 0% CPU for weeks, they might shut it down.

To prevent this, actually use it. Run a small monitoring tool, a media server, or a folding@home instance if you have to. Just keep the CPU usage slightly above the "dead zone" (usually around 10-15% for a certain percentage of the time).
Also, keep an eye on your email. Oracle sends notifications if they plan to retire a specific hardware shape or if there’s a maintenance window.
Actionable Next Steps
If you want to maximize this setup, start by creating your account with a clean, non-VPN IP address to avoid the fraud filter. Once you have your instance, don't just leave it as a bare Linux box.
Install Docker and Portainer. This makes managing that 24 GB of RAM much easier. You can deploy a "Home Lab" in minutes.
Setup a Cloudflare Tunnel instead of opening every port in your VCN. It’s more secure and handles the SSL for you.
Lastly, back up your data. "Always Free" is great, but it doesn't come with an enterprise-grade SLA. If Oracle decides to close your account or if the hardware fails, you want your config files saved elsewhere. Use a tool like Rclone to sync your important data to a secondary cloud or your local machine once a week.
This setup is hands-down the best deal in the cloud world. It takes some patience to get the instance provisioned, but once it’s running, you have a professional-grade server for the cost of absolutely nothing.
