Value-Added Technical Enhancements
-
Spec-Driven Dynamic Performance Optimization Upon first boot, the system automatically analyzes the underlying EC2 instance specs and dynamically applies tailored sysctl kernel adjustments, network buffer allocations, and disk I/O parameters.
Note: These automated adjustments provide a general-purpose, high-throughput cloud baseline. System administrators are encouraged to fine-tune specific kernel parameters according to their unique workload demands.
-
Automated Weekly Build Pipeline & Vulnerability Mitigation Our continuous integration pipeline rebuilds and validates this AMI weekly, integrating the latest upstream security advisories and critical CVE patches to significantly minimize post-boot update overhead.
-
Baseline Security Hardening Pre-configured with essential OS security baselines, a minimized default attack surface, and streamlined network access (OS firewall disabled by default).
-
Supplemental avoracloud Package Repository Includes a built-in custom RPM repository (avoracloud) providing pre-compiled AWS utilities (e.g., awscli-2, amazon-cloudwatch-agent, amazon-efs-utils, mount-s3, s3fs-fuse).
- Minimal Footprint by Default: To preserve upstream system purity, the avoracloud repository is disabled by default, and only amazon-ssm-agent is pre-installed out of the box.
- Testing Notice: Packages are compiled from upstream source releases. We recommend evaluating packages in non-production environments prior to production deployment.

Pricing
Pricing is based on actual usage, with charges varying according to how much you consume. Subscriptions have no end date and may be canceled any time. Alternatively, you can pay upfront for a contract, which typically covers your anticipated usage for the contract duration. Any usage beyond contract will incur additional usage-based costs.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.
If you are an AWS Free Tier customer with a free plan, you are eligible to subscribe to this offer. You can use free credits to cover the cost of eligible AWS infrastructure. See AWS Free Tier for more details. If you created an AWS account before July 15th, 2025, and qualify for the Legacy AWS Free Tier, Amazon EC2 charges for Micro instances are free for up to 750 hours per month. See Legacy AWS Free Tier for more details.

Dimensions summary
You pay by the hour for this hardened CentOS Stream 9 image, billed per running instance. Each dimension maps to one AWS EC2 instance type, so your rate depends on the instance you launch. Options span the full size range, from small burstable types like t3.nano up to large memory, compute, storage, and accelerated instances such as u7in-32tb.224xlarge and p6-b200.48xlarge. Larger instances with more CPU, memory, or GPU capacity carry higher hourly rates. You are not locked into a term; charges accrue only while an instance runs. Pick the instance type that fits your workload.
Top-of-mind questions for buyers
You get a hardened CentOS Stream 9 image with a minimized attack surface, kernel-level tuning for the AWS Nitro System, and tuned I/O and TCP settings. The vendor provides proactive vulnerability mitigations and quarterly updates. The software charge is separate from the AWS charge for the instance itself.
The hourly software charge accrues only while an instance runs. A stopped or paused instance does not generate software charges. Stopped instances may still incur AWS storage fees for attached volumes, but those are separate from this listing's per-hour software rate.
Each instance type maps to its own hourly rate. When you switch to a larger type with more CPU, memory, or GPU capacity, you pay that type's rate for the hours it runs. There is no upgrade fee; the new rate simply applies to the running time going forward.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
