CIS hardening has simplified secure container workloads but AppArmor still blocks Docker by default
The CIS L1 AppArmor enforcement breaks Docker out of the box. Containers fail to start with a permission denied on the containerd task directory. There is no documentation about this. A simple note explaining that Docker users need to either update the runc AppArmor profile or disable it would save a lot of debugging time. It takes a while to trace the failure back to AppArmor blocking runc writes to /run/containerd/.

Modern desktop delivery has become smoother and integration with current clients works reliably
In Switzerland, my clients, particularly in the banking sector, are cautious about moving data to the cloud due to legal concerns about US access. Therefore, some companies prefer keeping their data on premises to avoid compromising security.Currently, I primarily work on-premises, operating exclusively within shared hardware data centers and not utilizing cloud services such as Azure or AWS. We have experimented with Azure for some testing installations, but the overall costs associated with cloud services raise concerns. While we employ cloud solutions for backup, our infrastructure remains on-premises. For the product itself, Windows Server 2025 (Windows Server 2025) | Support by SupportedImages earns a solid rating of seven or eight from me because it is user-friendly to work with. My main frustration lies in the mandatory updates and newly introduced security features that complicate third-party software operations.

Quotes from Members

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

Pros

"The same-day engineering support has been very valuable."
"The pre-applied CIS L1 benchmark is the main selling point, as getting a hardened baseline without manual effort is genuinely useful and the Ubuntu 26.04 LTS base also means I'm on a supported, up-to-date kernel with long-term security patches."
"ClearScale Ubuntu 26.04 LTS is an excellent choice for organizations adopting cloud-native technologies and modern DevOps practices."
"Once you get that launch template dialed in, the image is incredibly solid."
"The hourly software charge is small relative to the engineering time we used to spend building and maintaining our own hardened AMI."
"The biggest advantage I find in Windows Server 2025 is that it is very user-friendly."
"A significant benefit of Windows Server 2025 is its smoother integration with Windows 11, particularly in network environments."
"What I appreciate about Windows Server 2025 (Windows Server 2025) | Support by SupportedImages is the full solution Microsoft provides, especially when it comes to the cloud part and security, with their Microsoft total solutions."
 

Cons

"Enterprise management and compliance tooling could be more comprehensive out of the box."
"The CIS L1 AppArmor enforcement breaks Docker out of the box."
"It'd be cool to have more detailed changelogs with each new release so we can see exactly what packages got updated without having to boot up a test instance and diff it ourselves."
"Because the firewall ships default-deny, the first launch in a new environment takes a little planning to open the exact ports the app and load balancer health checks need."
"Regarding security, I do not agree with Windows Server 2025 (Windows Server 2025) | Support by SupportedImages because I believe Linux is the best for securing servers."
"The main disadvantage of Windows Server 2025 (Windows Server 2025) | Support by SupportedImages is pricing, as customers choose some Linux versions, which are open-source editions."
"The changes that Microsoft made with the introduction of Windows Server 2025 (Windows Server 2025) | Support by SupportedImages did not enhance our security; rather, they made it harder due to uncommunicated security features being activated."
