Ah, I see. The Logtail agent, the LVS + NGINX architecture, and the triplicate data storage all make sense. But I'm a bit surprised the Logstore backend isn't more distributed for scalability.

Haha, a single machine for the Logstore backend? That's bold, I wonder if it can handle the real-time processing demands. Although, I guess Alibaba knows what they're doing.

Yeah, Alibaba must have some serious infrastructure in place to handle all that data processing

I'm not too familiar with the Alibaba Cloud Log Service, but the triplicate data storage sounds like a great way to ensure reliability. And the Logstore backend being on a single machine seems a bit risky to me.

A, B, and D seem to be the correct options here. Logtail is pretty neat, and the LVS + NGINX architecture is a classic for high-performance web services.
