EC2 instance types's exact network performance?

Question

I cannot find exact network performance details for different EC2 instance types on Amazon. Instead, they are only saying:

• High
• Moderate
• Low<

Answer 1

Almost everything in EC2 is multi-tenant. What the network performance indicates is what priority you will have compared with other instances sharing the same infrastructure.

If you need a guaranteed level of bandwidth, then EC2 will likely not work well for you.
