This product has charges associated with it for Hanwei's pre-integration of Apache Kafka 3.7 with CentOS Stream 9, security hardening, optimized performance configuration, AWS operational integration, and EC2 validation. Support with a 24-hour response target is supplementary.
Overview
This product provides Apache Kafka 3.7 pre-integrated with CentOS Stream 9 and delivered as an Amazon Machine Image (AMI) by Hanwei. The image applies Hanwei's security-hardening and optimized performance baseline, includes AWS operational integrations, and is built and exercised on EC2 before publication.
Marketplace software charges cover Hanwei's Kafka and operating-system integration, application of the security-hardening and optimized performance baseline, AWS operational integration, repeatable image construction, and final AMI validation. Hanwei support, including a 24-hour response target, is a supplementary service and is not the sole basis for the software charges.
What Hanwei Adds to Upstream Kafka
- Kafka pre-integration: Apache Kafka 3.7 is installed during the image build on CentOS Stream 9, reducing the software installation work required after launch. Kafka cluster topology, listeners, authentication, authorization, encryption, storage, and workload-specific settings remain under customer control.
- Optimized performance configuration: The standardized EC2 profile raises the file-descriptor limit from 1,024 to 65,536 and the memory-map ceiling from 65,530 to 262,144. The device receive backlog is raised from 1,000 to 16,384, the TCP SYN backlog from 128 to 8,192, socket buffer maxima are set to 16 MB, TCP congestion-window state is retained across idle periods, and the system journal is capped at 500 MB.
- Security-hardening baseline: SELinux runs in enforcing mode. SSH uses a vetted cipher, key-exchange, and MAC policy; X11 forwarding is disabled; the login grace period is shortened; authentication logging is verbose; direct root login and password authentication are disabled. Auditd runs a base rule set for privileged command execution. Kernel settings disable IPv4 and IPv6 ICMP redirects, log martian packets, use loose reverse-path filtering, restrict dmesg, disable setuid core dumps, and disable SysRq.
- AWS operational integration: AWS Systems Manager Agent is installed and enabled for Session Manager and Patch Manager. Chrony uses the Amazon Time Sync Service, and the root filesystem expands at boot when the attached root volume is larger than the image default.
- Build-date package baseline: Operating-system packages are sourced from official repositories at the versions available when the image is built. Customers remain responsible for evaluating and applying updates after launch.
- Repeatable build and EC2 validation: Each version is produced from the same versioned build and baseline process, then launched and exercised on EC2 before release.
Highlights
- Apache Kafka 3.7 is pre-integrated with CentOS Stream 9 through Hanwei's repeatable image-build process.
- A security-hardening and optimized performance baseline configures SELinux, SSH, auditd, kernel controls, resource limits, network queues, socket buffers, and journal limits.
- AWS Systems Manager, Amazon Time Sync Service integration, root-volume expansion, and pre-release EC2 validation are included.

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 a hardened Kafka 3.7 build running on CentOS Stream 9. Pricing is not tiered by features. Instead, each dimension maps to a specific AWS EC2 instance type, and every listed instance carries its own hourly software rate. Your cost depends on which instance you launch. Options span small general-purpose sizes up to compute-, memory-, storage-, and accelerator-optimized families, including bare-metal and very large instances. Larger or more specialized instances cost more per hour. You add AWS infrastructure charges separately, and you scale by choosing or changing your instance selection.
Top-of-mind questions for buyers
You pay for a hardened, pre-configured Kafka 3.7 build running on CentOS Stream 9. The software is self-contained and bundles the libraries and runtimes needed to run. The hourly rate is the software licence charge tied to the instance you launch. AWS charges for the underlying compute and storage apply separately.
The hourly software charge meters running instance-hours. A fully stopped instance does not accrue software charges. Stopped instances may still incur AWS storage fees for attached volumes, but the software licence bills only while the instance runs. You stop billing by stopping the instance.
You scale by choosing a different instance type or launching more instances. Each instance carries its own hourly rate based on its size and family. Larger, bare-metal, or specialized instances cost more per hour. Running several instances adds each one's hourly rate together on your bill.

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.
