I have an Alibaba Cloud ECS instance hosting a small website with a majority of domestic users. It involves storing a portion of images and videos, which I recently learned about through Alibaba Cloud's OSS. Upon reviewing the pricing, I found that the storage is very affordable, but external outbandwidth traffic is relatively expensive, whereas internal traffic is free. For image uploads, the OSS URI resembles this: https://oss-hangzhouxxxx.xxx.xxx.com. I directly place this URI in the image URL of my website and set it as the destination. When users access my website, this traffic is counted as internal traffic. However, if not, how can I configure it to count as internal traffic? Moreover, I understand that OSS can accelerate access speeds, but on my ECS instance, the bandwidth is limited. If I route traffic through the internal network, does it occupy the server's bandwidth?
