Amazon cordons off — but keeps selling — oldie but goodie EC2 instances

AWS: Reinvent

Amazon has taken some of its oldest EC2 instances, designated them as “previous generation” resources and  segregated them from newer, more robust instances on a separate page of their own. But it will keep selling those older instances, according to the AWS blog.

The company said this will bring the newer, more efficient processes to the fore for customers, but keep the older instances available for those who want them. At least for now.

IT vendors typically stop selling an older product after a set amount of time or number of updates and eventually “de-support” or “end of life” it. That’s what Microsoft is doing this week with its extremely popular but 13-year-old Windows XP. The first AWS instances came online in 2006 and 8 years is a long, long time in the fast-moving world of public cloud computing.

Keeping these older EC2 resources running may be fine for now, but at some point AWS will be forced to act, said Sebastian Stadl, founder of Scalr, a private cloud management provider that also tracks cloud usage.

If it holds to its current course, AWS will end up running older gear that would normally be recycled and replaced. Such equipment uses a lot of energy for electricity and cooling — especially if it is lightly utilized. There will be lots of unsold inventory and at that point, AWS — which is known for its efficiency — will have to either keep eating the cost, terminate client machines or develop live migration, technology  that enables users to move workloads from one set of resources to another without shutting down, he said. Google Cloud offers live migration but AWS does not (yet).

Amazon’s energy use is something of a sore point. The company prides itself on its energy efficiency but has also been slammed by Greenpeace for its reliance on “dirty,” i.e. non-renewable, energy compared to Facebook, Apple, and Google who hae committed to green energy sources. Greenpeace also said AWS is one of the least transparent tech companies about its energy use.

Server Density CEO David Mytton, an avid AWS watcher, agreed that Amazon will probably have to change course. “AWS said they’re not planning to deprecate [these instances] but that may change as the hardware ages and spare parts become more expensive. It could also be about efficiency to help reduce power and improve the environmental impact, even if AWS doesn’t release anything about how green they are.”
