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/.

Team collaboration has improved and project tracking is clearer but downtime still causes disruption
I think there are some parts of Lark that have not been translated, and sometimes there is a glitch where the product still uses Chinese words. Lark occasionally experiences downtime, and during those times, we usually use WhatsApp for communication and coordination, which can be frustrating. Regarding Lark's AI capabilities, I believe they are good in terms of governance and security. I think there is still room for improvement regarding the accuracy and reliability of Lark's AI output.

Quotes from Members

Pros

"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."
"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."
"Lark has positively impacted my organization because our team's work has become more noticeable by the management because we have a clear record of what's going on in the emails and with the work on the technical side."
"Lark has positively impacted my organization by helping us reorganize the to-do work, allowing us to focus more on our tasks."
"Lark has impacted my organization positively; it has been a daily driver and has been excellent."
 

Cons

"The CIS L1 AppArmor enforcement breaks Docker 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."
"Enterprise management and compliance tooling could be more comprehensive 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."
"Lark occasionally experiences downtime, and during those times, we usually use WhatsApp for communication and coordination, which can be frustrating."
"I have not seen a return on investment at this time; I cannot share any relevant metrics such as time saved, money saved, or fewer employees needed."
"Lark can be improved by having the ability to switch between personal and team space."
