Amazon shared that the new
c3.* instance types have been in high demand on EC2 since they were released.
I finally had a minute to take a look at the specs for the
c3.* instances which were just announced at AWS re:Invent, and it is obvious why they are popular and why they should probably be even more popular than they are.
Let’s just take a look at the cheapest of these, the
c3.large, and compare it to the older generation
c1.medium, which is similar in price:
|Effective Compute Units||5||7||+40%|
|Memory||1.7 GB||3.75 GB||+120%||Ephemeral Storage||350 GB||32 GB SSD||-90%, but much faster|
|Hourly on-demand Cost (us-east-1)||$0.145||$0.15||+3.4%|
c3.largeis 40% faster and has more than double the memory than the
c1.mediumbut costs about the same!
In fact, you only pay 12 cents more per day in
us-east-1 for the much better
I have been a fan of
c1.medium for years, but there does not appear to be any reason to use it any more. I’m moving mine to
If Amazon does not drastically drop the price on the
c1.medium, then it would look like they might be trying to move folks off of the previous generation so that they can retire old hardware and make room in their data centers for newer, faster hardware.
While we’re at it, here’s a comparison of the old
c1.xlarge with the new
c3.2xlarge which are also about the same cost with similar benefits for switching:
|Effective Compute Units||20||28||+40%|
|Memory||7 GB||15 GB||+114%||Ephemeral Storage||1680 GB||160 GB SSD||-90%, but much faster|
|Hourly on-demand Cost (us-east-1)||$0.58||$0.60||+3.4%|
In completely unrelated news… I’m selling some
c1.medium Reserved Instances on the Reserved Instance Marketplace in case anybody is interested in buying them.
