# Feature Comparison

Trong bối cảnh thị trường năng động của điện toán đám mây, Load Balancer là công cụ quan trọng để nâng cao hiệu suất ứng dụng và đảm bảo trải nghiệm người dùng liền mạch. Tại GreenNode, chúng tôi cung cấp hai loại Load Balancer chính: Application Load Balancer (ALB) và Network Load Balancer (NLB). Tài liệu này sẽ giúp người dùng hiểu được sự khác biệt và điểm mạnh của các loại Load Balancer này, từ đó đưa ra quyết định sáng suốt về loại nào phù hợp nhất với yêu cầu cho từng ứng dụng cụ thể.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.vngcloud.vn/vng-cloud-document/vn/vlb-load-balancer-new-version/feature-comparison.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
