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/.

Preconfigured containers have cut licensing costs and now save our team time with faster booting
ECS-Optimized Windows can improve by giving us new generation instances rather than the old generation's AMD chips or other older technology. It should use the new generation instances, and it should also modernize the storage and the file systems that it is using because those are very old and sometimes problematic. It should also improve or add advanced configurations to the things that we are doing so it can help us and give us more efficiency and productivity in our team. It should give us good analysis, particularly more detailed analysis, with the AWS tools because it is operated by AWS. It is cloud-based, and we are getting it from AWS, so they should also integrate it with AWS better.

Quotes from Members

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

Pros

"The hourly software charge is small relative to the engineering time we used to spend building and maintaining our own hardened AMI."
"Once you get that launch template dialed in, the image is incredibly solid."
"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."
"The same-day engineering support has been very valuable."
"ClearScale Ubuntu 26.04 LTS is an excellent choice for organizations adopting cloud-native technologies and modern DevOps practices."
"After deploying our Windows workloads using ECS-Optimized Windows on AWS, we saw improved reliability and measurable operational efficiencies."
"ECS-Optimized Windows has positively impacted my organization because I have been using it for proof of concepts and it increases the speed of running them because I do not have to worry about creating my own image."
"Our teams can scale at least 40% faster than before, accounting for waiting for it to boot and load everything."
 

Cons

"The CIS L1 AppArmor enforcement breaks Docker out of the box."
"Enterprise management and compliance tooling could be more comprehensive out of the box."
"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."
"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."
"ECS-Optimized Windows can improve by giving us new generation instances rather than the old generation's AMD chips or other older technology."
"Improvements for ECS-Optimized Windows could include faster Windows patch cycles, a lighter AMI footprint for quicker boot times, better visibility into container-level performance metrics, and improved cost optimization guidance."
"One problem with ECS-Optimized Windows is that the image size is quite large."

Questions from the Community

What is your experience regarding pricing and costs for ClearScale Ubuntu 26.04 LTS?
The hourly premium is honestly negligible compared to the salary hours I was wasting building, patching, and maintaining my own custom images. If you have a decent-sized fleet, look at the total co...
What needs improvement with ClearScale Ubuntu 26.04 LTS?
It would be cool to have more detailed changelogs with each new release so I can see exactly what packages got updated without having to boot up a test instance and diff it myself.
What is your primary use case for ClearScale Ubuntu 26.04 LTS?
I run a bunch of stateless REST APIs and web apps in AWS behind an Application Load Balancer. Everything lives in Auto Scaling Groups (ASGs). I use this AMI as the default base for those instances ...
What is your experience regarding pricing and costs for ECS-Optimized Windows?
I think ECS includes licenses, so it reduces the stress. Also, the cost is very low, at $0.04 per hour per version of the CPU. We can also get our own license. It follows the BYOL method. I told yo...
What needs improvement with ECS-Optimized Windows?
ECS-Optimized Windows can improve by giving us new generation instances rather than the old generation's AMD chips or other older technology. It should use the new generation instances, and it shou...
What is your primary use case for ECS-Optimized Windows?
My main use case for ECS-Optimized Windows involves utilizing the machines offered by AWS, which means a workload like the image of Windows, exactly. It is provided by AWS with right-sizing for the...
