Inbound vs Outbound

Posted June 26, 2018 14.5k views


Can someone explain to me more detail about the difference between Inbound and Outbound (Traffic/Bandwith).

And on the DO’s Storage, what does “1TB of outbound transfer” means?

Let say my 2 web users are watching the videos that are stored on my DO’s Storage, each one of them are watching 1Gb video, does it means that the “Outbound Transfer is 2Gb?” or it’s “Inbound Transfer is 2Gb”?

Thank You

Outbound transfer = data leaving DigitalOcean’s network.

Inbound transfer = data entering DigitalOcean’s network.

So if you have 2 web users watching a 1gb video served from a DigitalOcean Droplet or Storage, that will show up as 2GB Outbound transfer

If you have 2 web users uploading 1gb video to a DigitalOcean Droplet or Storage, that will not count against your outbound transfer because it is all inbound.

  • What about if I am requesting data from inside the server (e.g. scraping a web from my Digital Ocean server)? Is that outbound transfer or inbound transfer?fro

    • Short answer : Inbound Transfer.
      Long Answer:
      Consider inbound like Download and outbound like Upload.
      If your server requests data from an external source it will DOWNLOAD that data into the server. [INBOUND TRANSFER]
      If some user requested a webpage, the server will upload that page to the client side. [OUTBOUND TRANSFER]

Thank You for the clarify :)
