To compare:
CloudLayer: 1 Core + 1GB RAM + 100GB SAN Storage - $99.00
EC2: 1 Core + 1.7GB RAM + 100GB Elastic Block Storage - $82.00EDIT: SoftLayer is also saying that their base CPU is 2.0GHz rather than the 1.2GHz that Amazon's compute units are based off of.
I'm not exactly in the wily-nilly "VC money has caused me to lose all sense of proportion so I think I'm going to spend $20,000 on a nice big fishtank filled with tropical freaking bats" section of the market, but I look at $17 difference in these options or $8 difference in, e.g., Slicehost vs. Linode and wonder "What conceivable circumstances are there where this both matters and can not be compensated for by eating less pizza and more ramen?"
(Yeah, if you start buying dozens of them, it almost approaches real money every month. Of course, if you're buying dozens of them, you should ideally be running a business on top of them.)
It turns out the instances are only offered on a month-to-month deal, not by-the-hour.
Apparently the Pay As You Go only refers to the storage and CDN.
For example, Amazon's Elastic Block Storage can be snapshotted to S3 (with at least 3 copies in at least two availability zones) very easily. Does CloudLayer's SAN storage offer such ease of backups? I see EVault is offered for about $1/GB which is really expensive compared to Amazon's backups. Can IP addresses be transferred between boxes? What if the boxes are in different data centers? Is the billing only monthly or will it be pro-rated hourly? Can CloudLayer instances be used in conjunction with SoftLayer's hardware load balancing and other services like that which Amazon doesn't offer?
We use their iSCSI storage space for that, which is about 75c/GB (free server-to-server bandwidth). Their cloud storage appears to be even cheaper 25c/Gb
Or perhaps one needs to plan an architecture where you never block on any disk read, writes being usually buffered?
I'll note that my app probably relies a lot on files for data access rather than throwing everything in an SQL database (and I wonder how Postgres would fare on such a shared disk system)
The unlimited incoming bandwidth is great too.
