I actually did a market analysis of the EC2 spot price (they give you a year of price history in JSON format). The spot price was under the reserved price for all but a few hours since it came out. The savings in general were around 30-50% (depending on instance size), with higher savings coming from using spot market pricing in the non-VA markets (CA, EU, Asia), where prices were higher to start with.
Why don't people just bid the reserve price on the spot market, and never lose the bid? You'll still pay less...
- cperciva 16y agoWhy don't people just bid the reserve price on the spot market, and never lose the bid? Because you will lose the bid if a disaster occurs. A lot of reserved instances have been purchased for disaster-recovery purposes but aren't actively being used; those are instead being sold as spot instances. If a disaster occurs, the supply of spot instances will drop dramatically.
