How about Vultr cloud server? A brief evaluation of the cloud server in the Miami data center

Since Chinese people like to gather on the west coast of the United States, sometimes you can consider choosing the central and southeastern parts of the United States; vultr has a data center in Miami, southeastern United States, which is also where South American users are accustomed to gathering; but relatively speaking It may be said that the bandwidth and so on may be more abundant, but of course this is just a guess. What we bring to you this time is a simple evaluation of the cloud server in Vultr's Miami data center. You will know if it is suitable for you by looking at the data.

Supports multiple payment methods including: credit card, PayPal, Alipay and more!

The AMD series was selected for this test. We see that the CPU is the EPYC-Rome series. The approximate CPU model has been introduced by the webmaster in a series of previous articles... BBR and VULTR's own broadcast IP are enabled. Currently, Approximately the hard disk I/O is at 367MB/S:

Test it again with FIO and see the specific data read and written:

Let’s look at an important network data: uplink and downlink bandwidth. We use the nodes of speedtest.net to test. The first one is the nearest node, which at least shows that the bandwidth is 3Gbps... The other nodes are all from the three networks in mainland China. If you are working abroad, you don’t need to pay attention to the nodes in mainland China. Face China If it comes to mainland China, the node in mainland China is very important:

The same test, let’s take a look at the evening peak period when our backbone network explodes:

Follow the testing status of other nodes in Asia:

Let’s use iperf3 to run European and American nodes to see:

What should we look at if cloud servers are coming to mainland China quickly? Do you just look at the download speed? Opening a website actually means downloading something, right? Let’s directly use the browser to download the files stored on the test cloud server to see the speed (the webmaster is Guangzhou Telecom):

Similarly, let’s take a look at the download speed during the evening peak period during the backbone network explosion:

Delayed data under multi-node testing in mainland China:

On the outbound journey of telecommunications, the backbone network is connected to NTT and logged in from San Jose on the west coast:

China Unicom outbound, backbone network docking with twinve99:

Mobile outbound, international CMI docking pccw:

Return trip, China Telecom:

Beijing direction: Take level 3 from San Jose on the west coast to connect with the telecommunications backbone

Shanghai direction: Take PCCW and transfer to Telecom’s node in Miami to Telecom’s node in San Jose and then return directly to China

Guangzhou direction: Take GTT and transfer to Telecom’s node in Miami to Telecom’s node in San Jose and then return directly to China

Return to China Unicom:

Beijing/Guangzhou direction: take level 3 in Los Angeles and transfer to China Unicom at the level 3 node to return directly to China

Shanghai direction: similar to Beijing, except Los Angeles is replaced by San Jose

Return, move to mainland China:

Beijing/Guangzhou direction: take level 3 to China Mobile’s node in Seattle and return directly to China

Shanghai direction: Take NTT from Los Angeles to Tokyo, Japan and then to Hong Kong, then transfer to Hong Kong and come back

A rough summary:

In terms of the Internet, China Telecom and China Unicom use international routes. However, China Unicom International has its own advantages and is relatively better than China Telecom. China Mobile's return route looks good, but given that China Mobile In the field of international business, it is often nonsense; in the field of comprehensive network, this is basically not particularly ideal.

There is nothing to consider about the performance of the chicken. Basically, there is no need to worry, all parameters are pretty good.
