# Getting Started with vCDN

**Overview**

vCDN currently provides 4 services as follows:

* **Web Accelerator**: Use when you need to improve the loading speed of web resources (such as images, CSS, HTML5), optimize image capacity but still maintain image quality.
* **Object Download**: Use to improve the download speed of static files and update files for your system
* **VOD (Video on Demand)**: Use when there is a need to stream video. For example: Online movie streaming website
* **Livestream**: Used for live presentation needs. For example: movies, sports, game shows, sales advertisements, etc.

For regular Domectic (domestic) traffic, VNG currently does not guarantee speed for traffic from international sources. Customers can refer to the international vCDN service provided by GreenNode for the best quality with international traffic or contact <support@vng.com.vn> for further instructions.
