Amazon EC2 offers a lower price alterna+ve, where you book an en+re server for up to 3 years, in which case the price is:
$2800 3-‐year buy-‐in fee
+ $0.24 * 24 hours per day * 365 days per year * 3 years = $9107.20 per 3 years
Whereas at OU it's:
$0 buy-‐in fee + $0.35 * 24 hours per day * 365 days per year * 3 years = $9198.00 per 3 years
So if you commit to using an Amazon EC2 server for 3 years – all day every day -‐-‐ it's preLy much breakeven.
Using it less than all day every day makes it more expensive per server hour, because of the $2800 buy-‐in fee.
Of course, it's not really breakeven at all, because
Amazon
EC2 lacks the following
:
(a) high performance interconnect (at OU, Infiniband); (b) high performance parallel filesystem (at OU, Panasas);
(c) user services to help make people produc+ve (everyone on our team has experience working directly with users).
If any of the following are true, then cloud compu3ng may be cheaper than centrally-‐managed resources:
(i) your internal centrally-‐managed resources are expected to be idle a significant frac+on of the +me;
(ii) your users don't need a high performance interconnect; (iii) your users don't need high performance parallel I/O; (iv) your users don't need high end user services.
But if any of these is false, then you're probably beLer off, in terms of cost, having centrally-‐managed local resources.
But ...
... comparisons should be done vs
total
cost of ownership
- from start to finish.
This is one of the tasks in the NEON
project, mentioned later in this Q&A.
And. NEON cost comparisons will include
the value of flexible services and more.
5. Can I trust it?
“Cloud compu+ng is
about gracefully
losing control while maintaining
accountability
even if the opera+onal
responsibility falls upon one or more
third par+es.”
There are many benefits that explain why
to migrate to clouds

10:45-12:00: Hands on I
12-13: Lunch
13-13:30: Explain Cloud components II 13:30-15: Hands on II
15-16: User feedback, discussion, use cases that want to pilot?
The rest of the day
10-10:30: Explain cloud components I : Storage, computing components named and explained. Explain command line tools vs AWS console vs Rightscale.
10:30-10.45: Coffee break
10:45-12:00: Hands on I : Obtain AWS credentials, obtain command line tools for VM management and S3 management. Goal: launch a default Fedora 8 32 bit VM.
12-13 - Lunch
13-13:30: Explain Cloud components II: RDS, SimpleDB, SQS application design 13:30-15: Hands on II : Start a VM (again), install anysoftware you like, then go through the process of bundling. Start from your bundle. If a user has time left: create an EBS and attach that to your VM. If a user has no software to install, use the s3-tools from this morning.
