What can the 1M bandwidth of Alibaba Cloud ECS do?

       The ECS machines that Alibaba Cloud is currently engaged in are generally 1M bandwidth. Therefore, when Alibaba Cloud was promoted recently, many people asked me, "Can a 1M small water pipe do it?". In the era of 100M home broadband, 1M bandwidth is indeed a problem that most people will worry about. This article will introduce the meaning of the fixed 1M bandwidth of Alibaba Cloud ECS to everyone.

        For a better understanding, we need to first explain the words "downlink bandwidth" and "uplink bandwidth":
Downlink bandwidth: The rough explanation is the maximum bandwidth of downloaded data. A more precise description is the maximum bandwidth of data entering the machine.
Upstream bandwidth: A rough explanation of the maximum bandwidth for uploading data from the local machine. To be more precise, it is the maximum bandwidth of data from the local machine.


        The 1M bandwidth of Alibaba Cloud Cloud Server (ECS) alone refers to the maximum upstream bandwidth of the server, that is, the maximum bandwidth of data flowing out of the server. Think about your 100M bandwidth at home and download a 100M file from my openGPS.cn website. The estimated theoretical time is 100 seconds. The reason is that my openGPS.cn website is placed on Alibaba Cloud with 1M bandwidth. on ECS. You download the resources on my openGPS.cn at home, which occupies the upstream bandwidth of the openGPS.cn website server. The shortest board is showing slowness at the upstream bandwidth of my server.

        What has been ignored by everyone is the downlink bandwidth of Alibaba Cloud Cloud Server (ECS). Is this 1M? No, the bandwidth of Alibaba Cloud ECS adopts an unequal structure, and there is no upper limit on the downlink bandwidth of the server, which means that the maximum speed depends on the link speed. Xiaobian once installed Xunlei in the openGPS.cn server. In 2014, when Alibaba Cloud's business was not that large, the highest stable download speed once reached 22MB/S, which is 220M bandwidth when converted into bandwidth! ! ! Scary, right? The bandwidth of the server purchased is only 1M! In fact, even those computer rooms that are currently full of Alibaba Cloud business can still achieve a stable speed of more than 10MB/S. How to understand this data. Suppose my website has a function for uploading files, even if your file has 100M, it may only take 1 second to upload it from your home's 100M broadband to my openGPS.cn server! ! ! This is a world away from the 100-second download I just mentioned.

        How to plan bandwidth usage on Alibaba Cloud services like openGPS.cn? It's very simple, make use of its strengths and avoid its weaknesses. Large files such as pictures, audios, videos, attachments, etc. are sent to the server via the ECS downlink broadband, but the server uses the intranet to transfer to the OSS object storage service in the same availability zone at high speed. When these files are to be provided externally, the user downloads them from the OSS that is billed by traffic (unlimited speed). In this way, it is easy to use the high-speed channel with unlimited speed in the upload and download links. The time-consuming of the whole process is greatly reduced.
        Here, the editor mentioned OSS. OSS is an object storage service provided by Alibaba Cloud. To put it bluntly, it is a place where files are stored on a network path. OSS only needs to purchase storage space and downstream traffic packages to reduce costs. In addition, OSS can easily configure and enable the CDN function to achieve local acceleration of static files.
