What is Network In and Network Out at Amazon?

If you have an instance with 10 Gigabit Ethernet. What does it mean? How many bytes do you have on the network and how many maximum in Network Out?

In Cloud Watch reports, I see 80,000,000 in Network In and 800,000,000 in Network Out. As it approaches 120 million online, the site starts loading slowly, and some images or assets do not load. This is maximum?

  • 10 Gigabit Ethernet, suppose it has full duplex, so the maximum network is In = max Network Out = 10 Gb / s = 1.25 GB / s.

Gbps: Gigabit per second; GB: Giga Byte; MB: Mega Byte

  1. Cloud Watch, 80,000,000 in Network In means 80MB in 60 seconds. 120,000,000 in Network In => 120MB / 60s => 2 Mb / s => 16 Mb / s, this is far from the maximum of 100 Mb / s. But it depends on what type of instance you are using.
