How about kamatera? Cloud server evaluation in Toronto, Canada data center

How about kamatera? How about kamatera Canadian cloud server? Kamatera has its own data center in Toronto, Canada, North America, and operates the Canadian cloud server business. The default bandwidth is 10Gbps, and it uses high-end CPU and NVMe SSD arrays. The overall physical performance of the cloud server is quite outstanding. As for whether kamatera's Canadian cloud server is suitable for the three-network environment in mainland China, we have to look at the actual measurement data this time, for reference only.

Established in 1995. Although the company is registered in the United States, it is actually an Israeli company; it mainly operates in Israel (5 data centers), the United States (5 data centers), Canada, the Netherlands, Germany, the United Kingdom, Italy, Sweden, Cloud server business in Spain.

Minimum configuration cloud server

I really don’t know how big the bandwidth is. The webmaster has tested cloud servers in all 18 data centers. The highest is 15Gbps and the lowest is more than 1Gbps, so I can’t tell how big it is.

• Memory: 1G
• CPU: 1 core
• Hard disk: 20G SSD (SAN array)
• Traffic/Bandwidth: 5T/month, 1Gbps
• Price: $4/month
• Purchase link

The CPU is Intel Xeon Platinum 8358P (factory in the second quarter of 2021, 32 cores, 64 threads, main frequency 2.6GHz\acceleration frequency 3.4GHz), BBR is enabled, its own ASN, belongs to Toronto, Canada, the current I/O is roughly 1262MB/S：

Latency test data of multi-nodes of three networks in mainland China:

Telecom's outbound journey: Directly connect to Telecom's San Jose node in the United States and then take GTT to Canada

China Unicom's outbound journey: directly connect to China Unicom's Los Angeles node in the United States, and then take GTT to Canada

Mobile outbound journey: Directly connected to Mobile’s Los Angeles node in the United States, then took the cogent and circled around the United States before going to Canada

Telecommunications return trip: I took the cogent from Canada to a lot of places in the United States and finally returned to China from San Jose

China Unicom return trip:

Beijing direction: take GTT directly from Canada to Los Angeles in the United States, and directly connect to China from China Unicom's Los Angeles node to return home

Shanghai direction: Take GTT from Canada directly to Los Angeles, USA to return home

Guangzhou direction: Take GTT from Canada directly to San Jose in the United States, and directly connect to the sea from China Unicom's San Jose node to return home

Mobile return trip: take cogent from Canada through the United States and finally return to the sea from Los Angeles or San Jose. Among them, the Shanghai and Guangzhou directions are directly connected to the sea from the West Coast mobile node

Cloud server performance test, some test results:

A rough summary:

The performance of the cloud server is quite high, whether it is the CPU score or the performance of hard disk reading and writing data, it is very niubi!

In terms of network, we basically take the GTT or cogent international route from Canada through the United States and then return to China from the West Coast of the United States. Some of China Unicom and China Mobile are directly connected from their own nodes on the West Coast of the United States to return to China.
