Production-ready NixOS 25.05 AMI for AWS: Immutable, declarative Linux distribution with enterprise-grade security hardening. Perfect for Infrastructure as Code, DevOps workflows, and reproducible cloud deployments. Includes XRDP + KDE Plasma desktop environment support. This is a repackaged software product wherein additional charges apply for seller maintenance.
Overview
Welcome to Base NixOS 25.05, a production-ready Amazon Machine Image (AMI) engineered for modern cloud infrastructure on Amazon Web Services (AWS). Built on NixOS 25.05, the latest stable release of the revolutionary immutable Linux distribution, this AMI combines cutting-edge technology with enterprise-grade security practices to deliver a robust, reliable, and reproducible cloud computing foundation.
Why NixOS for Cloud Infrastructure?
NixOS represents the future of Linux distributions, offering an immutable, declarative approach to system configuration that eliminates configuration drift and ensures perfect reproducibility across environments. Unlike traditional Linux distributions, NixOS treats your entire system configuration as code, enabling you to version control, test, and deploy infrastructure changes with confidence.
Enterprise Security Hardening
This AMI comes pre-configured with security best practices out of the box:
- Firewall Enabled: Built-in firewall protection to secure your instances from unauthorized access
- SSH Hardening: Password authentication disabled, root login disabled, ensuring only key-based authentication
- Minimal Attack Surface: Only essential services enabled, reducing potential vulnerabilities
- ECDSA Key Support: Modern cryptographic standards with ECDSA key support (RSA deprecated)
Cloud-Optimized Configuration
Designed specifically for AWS EC2 environments:
- Default User: Pre-configured ec2-user account with sudo privileges, ready for immediate use
- Cloud-Init Compatible: Seamless integration with AWS cloud-init for automated instance configuration
- Minimal Footprint: Lightweight installation optimized for cost-effective cloud deployments
- XRDP + KDE Plasma Ready: Optional desktop environment support for remote graphical access

Dimensions summary
You pay by the hour for the EC2 instance type you run this NixOS 25.05 image on. Each dimension maps to a specific AWS instance type, so pricing is not tiered by features. Instead, it scales with the compute size and family you select. Smaller instances like t3.nano or m1.small carry lower hourly rates. Larger or specialized instances, such as memory-heavy u-series, GPU g5 and p5 types, or bare-metal .metal options, cost more per hour. All instances run the same base software. You choose the instance that fits your workload and budget.
Top-of-mind questions for buyers
Each dimension maps to one running EC2 instance of that type. You pay per instance-hour for the vCPU, memory, and storage that instance family provides. Running the NixOS 25.05 image on a larger instance type raises the hourly rate. Running one instance means one hourly charge.
The hourly software charge meters running time only. A stopped instance does not accrue the software rate. You may still pay underlying AWS storage fees for attached volumes while stopped. Charges resume when the instance runs again.
No. Version upgrades run in place using nixos-rebuild and do not change your rate. Your hourly charge depends only on the EC2 instance type you selected. Moving to a larger instance is what changes cost, not updating the software.
