What Are Edge Servers, and How Do They Differ from Traditional Servers?

Hi everyone! 👋
I’ve recently come across the term edge servers, and I’m curious about how edge servers [ https://www.lenovo.com/ch/... ]work. From what I understand, they seem to work differently from traditional servers, but I’m not entirely sure how. Can someone explain in simple terms?
Here are some things I’d like to know:

1. What exactly are edge servers, and what do they do?
2. How are they different from traditional servers used in data centers?
3. What are the benefits of using edge servers for businesses or applications?
4. Are there any downsides or challenges when it comes to edge servers?

If you’ve worked with edge servers or have any insights, I’d love to hear your thoughts! Examples or real-world use cases would be super helpful.

Thanks in advance! 😊
