Honestly, the first time I heard about the Oracle Always Free resources 24 GB RAM server, I thought it was a total marketing lie. Nobody just gives away 24 gigs of RAM for nothing. AWS doesn't do it. Google Cloud certainly isn't that generous. Most "free tiers" in the cloud world are basically just enough to run a tiny Linux script that pokes a website once an hour. But here comes Oracle, a company usually known for aggressive sales tactics and enterprise contracts, handing out ARM-based instances that are beefier than most people's home laptops. It feels like finding a Ferrari in a "free stuff" bin.
But is it actually usable? Or is there a catch that makes it a nightmare for actual developers?
What makes this 24 GB RAM server actually tick?
To understand why this is a big deal, you have to look at the Ampere A1 Compute instances. Oracle Cloud Infrastructure (OCI) uses these ARM-based chips. Unlike the traditional x86 architecture you find in Intel or AMD chips, ARM is incredibly power-efficient. This efficiency is exactly why Oracle can afford to be so generous. Under the "Always Free" umbrella, you get 3,000 OCPU hours and 18,000 GB hours per month.
What that translates to in plain English is simple: you can run one massive virtual machine with 4 OCPUs and 24 GB of RAM, or you can split that up into four smaller servers. It’s flexible. You aren't locked into one giant box.
Most people use it for hosting game servers. Minecraft players, in particular, have flocked to this. Minecraft is a memory hog. If you've ever tried running a modded server on a 2 GB VPS, you know the pain of constant lag and "Can't keep up!" errors. Giving a Minecraft instance 12 or 16 GB of RAM for free is a game-changer. It’s also become a go-to for Docker enthusiasts who want to self-host a dozen different apps like Nextcloud, Pi-hole (via a VPN), and Home Assistant without the hardware ever breaking a sweat.
The "Out of Capacity" struggle is very real
Here is the part where the dream kinda hits a wall. Because the Oracle Always Free resources 24 GB RAM server is such an insane value, everyone wants one. If you try to sign up in a popular "home" region like Ashburn, London, or Frankfurt, you will likely see a depressing error message: "Out of host capacity."

It’s annoying. You’ve filled out the credit card info—yes, they need a card for identity verification—and you’ve set up your SSH keys, only to be told there's no room at the inn.
People have literally written scripts to spam the Oracle API every minute just to snag an instance when someone else deletes theirs. It’s a bit of a "Hunger Games" situation in the cloud. If you are signing up today, my best advice is to pick a less "trendy" geographic region. Phoenix or some of the smaller European data centers often have better availability than the major hubs. Once you pick a home region, you are stuck there for life on that account. Choose wisely.
Let’s talk about the networking and storage bits
RAM is the headline, but the rest of the specs aren't slouching. You get 200 GB of block storage. That’s plenty for a boot drive and a massive database. Most free tiers give you 30 GB and tell you to be happy with it. Oracle also gives you 10 TB of outbound data transfer.
10 terabytes.
That is an absurd amount of bandwidth for a free account. You could host a fairly popular blog or a private media server and never even get close to that limit. The ingress (data coming in) is always free anyway.

The catch? The boot volumes. If you create too many test instances and don't delete the volumes, you'll hit that 200 GB limit fast. Also, Oracle has a tendency to reclaim "idle" instances. If your server is just sitting there doing nothing—less than 10% CPU usage—they might turn it off. They’ll email you first, but you need to actually use the resources you're taking up. It’s a "use it or lose it" policy that keeps the capacity available for people who actually need the power.
Why ARM architecture might trip you up
If you are used to standard Intel-based servers, there's a slight learning curve. Not every piece of software is compiled for ARM64 yet. While major stuff like Nginx, Python, Node.js, and Docker work perfectly, some obscure older binaries might refuse to run.
I’ve run into issues with certain older game server wrappers or specific proprietary database tools. However, the world is moving toward ARM (thanks, Apple Silicon), so this is becoming less of an issue every day. Most modern Linux distributions available on OCI, like Ubuntu 22.04 or Oracle Linux, have massive repositories of ARM-compatible software.
Setting it up without losing your mind
Security on OCI is "deny by default." This trips up almost everyone. You’ll install your web server, you’ll see it’s running in the terminal, but when you go to the IP address in your browser... nothing. Timed out.
You have to navigate the VCN (Virtual Cloud Network) settings. You need to open "Ingress Rules" for port 80 and 443. Then—and this is the part people forget—you usually have to open the ports in the local iptables or ufw firewall inside the Linux OS itself. It’s two layers of security. It's frustrating for five minutes, then it makes total sense.

Is there a hidden cost?
Oracle requires a credit card to verify you aren't a bot. They might do a small temporary hold of about $1, which disappears in a few days. If you stay within the "Always Free" limits, you will never be charged a cent. I’ve had an account since 2021 and my bill has been exactly $0.00 every single month.
The real "cost" is the risk of account termination. There are horror stories on Reddit about people's accounts being closed without warning. Usually, this happens because of a violation of the Terms of Service—like crypto mining. Don't even try to mine Monero on these. You'll get banned within hours. Also, ensure your account details match your credit card exactly. Any hint of fraud or "multiple accounts" and the automated system will nukes your access.
Actionable steps for your first 24 GB instance
If you're ready to jump in, don't just click buttons randomly. You want to maximize this.
- Sign up with a clean identity. Use your real name, a non-VOIP phone number, and a credit card that matches your address. Using a VPN during signup often triggers a fraud alert and gets your application rejected instantly.
- Pick a "boring" region. Avoid the tech capitals if you want that 24 GB RAM capacity immediately.
- Use the Ampere A1 shape. When creating your instance, look for the "Change Shape" button. Select "Ampere" and "VM.Standard.A1.Flex."
- Max it out (carefully). You can slide the bars to 4 OCPUs and 24 GB of RAM. If it says "Out of Capacity," try reducing it to 2 OCPUs and 12 GB, then upgrade it later when more hardware is racked in the data center.
- Set up Monitoring. Since Oracle reclaims idle instances, run a small script or a heartbeat monitor to keep the CPU usage slightly above the 10% threshold if your main app is very lightweight.
- Backup your data. Because this is a free service, you don't get a service level agreement (SLA). If the account gets closed or the hardware fails, your data is gone. Use a tool like Rclone to sync your important files to a different cloud or a local drive once a week.
The Oracle Always Free resources 24 GB RAM server is arguably the most powerful free tool available for developers and hobbyists today. It requires a bit of patience to navigate the UI and the capacity shortages, but once you're in, you have a production-grade server for the cost of zero dollars. It’s a massive playground for learning Linux, hosting apps, or just seeing what ARM architecture can really do when it's pushed to the limit.
