What is Cloud Computing?

Part I: Website Enumeration

Is it in the cloud?
Given a site…
Reverse DNS
IP block / WHOIS

Reverse DNS
> host mydrifts.com
mydrifts.com has address 75.101.155.188
> host 75.101.155.188
188.155.101.75.in-addr.arpadomain name pointer ec2-75-101-155-188.compute-1.amazonaws.com.

WHOIS
> host ohmygov.com
ohmygov.com has address 173.1.162.2
> whois 173.1.162.2
GoGrid NET-173-1-160-0-1173.1.160.0 - 173.1.175.255

Now we just need…
… a big list of sites!
 Quantcast top 500,000
Not covered:
WWW site not in the cloud
Backend / back office
Research & Development
etc.

And the winner is…

So what’s next?
More providers
vCloud Express
Regional
More data sets
Global base
Definition of cloud?

Part II: Resource ID Analysis

Amazon EC2 Resource IDs
Instance i-31a74258
Reservation r-01764c79
Volume vol-d62bddbf
Snapshot snap-b9ab03d0
Image ami-11ca2d78

Is there a pattern?

Anatomy of an EC2 Resource ID
Image credit: Wikimedia / Lienhard Schulz

i-31a74258

Type Instance
i – instance
r – reservation
vol – EBS volume
snap – EBS snapshot
ami – Amazon machine image
i-31a74258

Type Instance
Inner Marker  Inner ID: 0258
XOR with 4000
i-31a74258

Type Instance
Series Marker  Series ID: 00
XOR with leftmost digits of Inner Marker
(42) then XOR with e5
i-31a74258

Type Instance
SuperseriesMarkerSuperseries ID: 00
XOR with rightmost digits of Inner Marker
(58) then XOR with 69
i-31a74258

Type Instance
SuperseriesMarkerSuperseriesID: 00
Instance 00-00-0258
i-31a74258

Quirks, Notes & Caveats
Instance IDs are always sometimes even
Reservation IDs too
Each EC2 region is entirely separate
Different constants
It’s all circumstantial!

Show us the results already!

What do Amazon say?
Officially:
Nothing.
Off the record:
Plausible

EC2 Rumors & Revelations
From Randy Bias (CloudScaling.com)
40,000 servers
16.25MW total power (servers only)
95,000 sq ft (servers only)
Target cost/server: $2,000-$2,500
Utilization rate was 70-75%

EC2 Rumors & Revelations
Inferred Revenues:
$220M / year
Amazon Other Revenue for 6mo: $260M (+10% Y/Y)
Est. Cloud IaaS market:$400-600M, 10-20% Y/Y growth (during a downturn!)

Conclusions?
Cloud infrastructure is growing – fast!
Amazon Web Services leads the pack
This is only the beginning…
