Traffic

Overview

Data exchange between computers is called traffic, and in cloud computing, this is an important topic at least from two angles:

• performance
  • throughput
  • latency
• cost
  • data volume
  • timeframe

So let’s look into it.

Internal Traffic 🔗

Definition Internal:

• Between all Exoscale Services inside a zone
• Between all Exoscale Services beyond zone borders

Internal traffic is free!

Incoming Traffic 🔗

Traffic coming from the internet is free.

Outgoing Traffic 🔗

Traffic towards the Internet is billed. BUT, it comes with a free tier at Exoscale:

• 1.42 GB per instance in the period of one hour
• Free traffic is shared in the organization
• Free traffic is only available in the hour created

Example 🔗

Two examples to illustrate the free tier and the billing aspects:

• Instance A and B
  • A creates 2 GB of outgoing traffic
  • B creates 0.5 GB of outgoing traffic
  • Completely under free tier, as both together have 2.84 of free traffic
• Instance A exist inside one hour
  • A creates 2 GB of outgoing traffic
  • 1.42 GB are free, 580 MB are to be paid
