They will, but only for people who didn't lock in a reserved instance. Amazon doesn't typically upgrade instance types, but rather introduces new ones. So if you lock in a t2.micro instance for a 3-year reserved period, you are stuck with exactly those specs for 3 years. If they introduce a t3.* instance class next year, you don't get a free upgrade to the new specs.

- _delirium 12y agoThat increases the flexibility, but afaict doesn't help with the upgradeability angle. When Amazon passes along the technological dividend by creating new instances with a better price/performance profile, it's usually as new family types. So your reserved t2.* instance can swap with other t2.* instances, but won't be able to take advantage of any t3.* instance that's introduced in the future. It's not a huge deal, just something to take into account when projecting out costs: the 3-year reserved instances are locking in today's prices until 2017, in return for a discount over today's non-reserved prices. Whether this produces long term gains requires some assumptions about how the market will change over the next 3 years.
