Automated hardening has standardized our servers and reduces effort for secure Windows workloads
The first-boot time is longer than a stock Windows AMI. Sysprep and the initial hardening pass add a noticeable delay before the instance is reachable, which is something to account for if you autoscale and need nodes ready quickly. The hardened defaults also occasionally trip up common installers and agents. A few of our deployment and monitoring tools assumed services or policies that the image had locked down, so we had to add exceptions. A short compatibility checklist of what the hardening changes from a default Windows install would have saved us that debugging. I would also like the option of a CIS Level 2 build for our more sensitive workloads since the image currently only ships a Level 1 baseline. Thanks.

Optimized database workloads have run securely and reduced licensing costs through virtualization
The major advantage of Oracle Linux 9 | Support by SupportedImages is that the update is free. Not just the patching and other things, but the update, some classes and other things, and some packages which I get free updates. If someone wants to use it, the license is free. If someone needs support, they can purchase the support. If someone does not purchase the support, there are free updates from Oracle. This is the major advantage to the customer, as they say that they are getting updates free. With Red Hat Linux, I have to purchase the support, otherwise I cannot get the update. Customers prefer that they are using it free and getting the update, and if they need support, they can purchase it anytime. The other part is that Oracle database runs well on Oracle Linux 9 | Support by SupportedImages. Whenever there are Intel servers in customer places and customers want to run Oracle database, they prefer Oracle Linux 9 | Support by SupportedImages. Oracle Linux 9 | Support by SupportedImages has very better security, but a few of the packages of Oracle still are not compatible with Oracle 9. So still in database perspective and grid perspective, I prefer 8. The feature is that it is very stable, memory consumption is low, and no additional service runs in the background. I can minimize the additional services if I want to stop it, it will stop. It is basically Red Hat Linux modified kernel, so those who know Red Hat Linux earlier can easily use Oracle Linux 9 | Support by SupportedImages. The other thing is that whenever I require, I can use the KVM of Oracle Linux 9 | Support by SupportedImages free of cost for virtualization. The Unbreakable Enterprise Kernel is a valuable feature. Security part differs, as it is built by the security team and the operating system team must enforce it. However, installation is very easy. Anyone can install it within twenty minutes without issues.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Windows Server 2025 is a strong fit for enterprise environments heavily reliant on Microsoft technologies."
"Because the image arrives CIS Level 1 hardened with the AWS tooling already in place, our servers come up patched, locked down, and ready to join the domain without a separate build out pass."
"I have not come across a single instance where it does not pass through all those security postures or possible threats."
"When you run your data center in Oracle Linux 9 | Support by SupportedImages and use Oracle KVM, the value of your ROI is a maximum of two years."
"We seamlessly connect, except that there must be a VPN connection to be established."
"In my experience, both Docker and containerd are very supportive with no issues running any containerization engine."
"What I appreciate about Oracle Linux 9 | Support by SupportedImages is that it is similar to the RPM-based image and Red Hat, making it easier for us to get the necessary libraries related to Red Hat Linux."
"Switching to Oracle Linux 9 | Support by SupportedImages saved us around one million SAR in licensing uplift, but it did not save on employees or time, and switching required additional training."
 

Cons

"The hardened defaults also occasionally trip up common installers and agents: a few of our deployment and monitoring tools assumed services or policies that the image had locked down, so we had to add exceptions."
"Initial configuration complexity can still be high for teams without prior Windows Server expertise."
"When it comes to response time and first-level support quality, if I escalate the SR, that is when I get more attention."
"Technical support by Oracle was good, always. However, for the last few months, my customers have expressed significant frustration."
"I gave Oracle Linux 9 | Support by SupportedImages a rating of nine and Oracle support a rating of five because of the difficulty in reaching a working solution and the lack of experienced consultants provided."
"Sometimes integrated downline embedded packages are already end-of-life, but Oracle is using them, which is much different from Ubuntu or Oracle."
"The graphical management is not yet up to the mark compared to Red Hat Linux."
