Instagram has released a preview of how the advertisements that its users will soon be seeing—as soon as next week if you're in the US—will appear. This is a one-time ad from Instagram to serve as a taster. Real ads will start with those from a select few brands that already make use of the service.
Advertisements will be identifiable by a 'Sponsored' label in the top right corner, where the timestamp would normally be. So that Instagram can determine what works and what isn't so successful in terms of adverts, you can tap on the '...' button to hide an advert and explain what made it unappealing.
I've already made the case for adverts on Instagram; this example looks tasteful enough but of course you can't be sure what any other company will come up with. They are, however, easy enough to identify as adverts.
