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.

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.
