Introducing Jim
This is Jim
Introducing Jim
Jim is an IT Architect
Introducing Jim
For a large pharmaceutical
Introducing Jim
Jim’s Boss (the CIO) has asked him to “move their company to the cloud”
Introducing Jim
Jim has no idea what this means
Introducing Jim
Jim has heard of cloud computing, but is lost when it comes to the terminology
Introducing Jim
Is cloud computing just about virtualization in the data center?
http://www.computerworld.com/action/article.do?command=viewArticleBasic&articleId=9121923
Introducing Jim
Is cloud computing just another term for software as a service?
http://www.daniweb.com/blogs/entry3993.html#
Introducing Jim
Is cloud computing something new?
http://www.cloudviews.org/2009/01/is-this-cloud-thing-something-new/
Introducing Jim
Is cloud computing for stupid people?!
http://cloudcomputing.sys-con.com/node/692407
Introducing Jim
Goal of the next 55 minutes:Help Jim “demystify” the cloud
Introducing Jim
Help him understand the terminology surrounding cloud computing
Introducing Jim
Show Jim what applications make sense in the cloud, and why
Introducing Jim
Teach Jim the important considerations for moving to the cloud
Terminology
Terminology
Buzzword Bingo
Terminology
SOA – Service Oriented Architecture
Terminology
SaaS – Software as a Service
Terminology
Web 2.0
Terminology
RIA – Rich Internet Applications
Terminology
Software + Services
Terminology
Are any of these cloud computing?
Terminology
Not really – these are styles of application architecture
Terminology
These styles may work in the cloud, but by themselves they are not cloud
computing
Terminology
To understand cloud computing, we need to instead start by looking at
where applications live
Where does my application live?
Where does my application live?
On Premises
Where does my application live?
I purchase my own hardware and manage my own datacenter
Where does my application live?
Order 10 servers from DELL, they arrive a week later, I un-box them and
install them in racks
Where does my application live?
Traditional way of doing things – has worked well for Jim the past few
decades
Where does my application live?
Application runs on-premises
Buy my own hardware, and
manage my own data center
Application runs on-premises
•Bring my own machines, connectivity, software, etc.•Complete control and responsibility•Upfront capital costs for the infrastructure
Where does my application live?
Hosted
Where does my application live?
I pay someone to host my application using hardware I specify or provide
Where does my application live?
“Dear hosting company, please set me up 2 x dedicated Web servers and 1 x
database, backed up nightly”
“Sure – that’ll be $21.99 per month”
Where does my application live?
Used heavily for public web site and/or company extranet and partner sites

software from another vendor
Where does my application live?
Public Cloud
Where does my application live?

software
Where does my application live?
Jim now understands the style of an application, and where it lives, but who
creates the application?
Where does my application live?
Build vs. Buy

Jim’s Applications
So, all of this looks great in PowerPoint…but what else should Jim be considering?
Your datacenter is not like a cloud datacenter
Your datacenter is not like a cloud datacenter
Each data center is 11.5 times
the size of a football field
Your datacenter is not like a cloud datacenter
When you have this many machines to look after, the rules change
Your datacenter is not like a cloud datacenter
MTBF (Mean Time Between Failure)
Your datacenter is not like a cloud datacenter
Approximate lifetime value that manufacturers state for system
components
Your datacenter is not like a cloud datacenter
Average Manufacturer Disk MTBF = 1M hours
= failure every 114 years
(Does not mean that every disk will last 114 years – calculated using batch of 1500 disks running for 30 days without failure)
http://www.datarecovery.com.sg/data_recovery/disk_drive_mean_time_failure.htm
Your datacenter is not like a cloud datacenter
Average Manufacturer NIC MTBF = 44 years
Your datacenter is not like a cloud datacenter
Average CPU Cooling Fan MTBF = 22 years
Your datacenter is not like a cloud datacenter
Statiscally, with 20,000 machines this equates to 2 or 3 machines out of order
every day
Your datacenter is not like a cloud datacenter
Which isn’t bad
Your datacenter is not like a cloud datacenter
Except if it’s your machine!
Your datacenter is not like a cloud datacenter
What does this mean?
Your datacenter is not like a cloud datacenter
Management of a cloud datacenter has to be done differently
Your datacenter is not like a cloud datacenter
“Pager at 2am”vs.
“9 – 5 datacenter management”
Your datacenter is not like a cloud datacenter
Different replacement strategy
NICNIC ServerServer RackRack ContainerContainer
Your datacenter is not like a cloud datacenter
Your datacenter is not like a cloud datacenter
What does this mean for Jim?
Your datacenter is not like a cloud datacenter
Jim’s team’s approach to application architecture has to change
Your datacenter is not like a cloud datacenter
Away from the approach of a single application running on a single machine
Your datacenter is not like a cloud datacenter
Need to move from ACID transaction model to BASE transaction model
Your datacenter is not like a cloud datacenter
ACID = Atomic, Consistent, Isolated, Durable
(traditional transactional commit model)
Your datacenter is not like a cloud datacenter
Really difficult to implement ACID transactions in distributed systems
(actually an anti-pattern)
Your datacenter is not like a cloud datacenter
Spend a lot of money trying and still not get working perfectly
Your datacenter is not like a cloud datacenter
BASE = Basically Available, Soft state, Eventually consistent
Your datacenter is not like a cloud datacenter
It’s OK to be wrong, as long as consistency is achieved eventually
Your datacenter is not like a cloud datacenter
Compare the cost of an apology vs. the cost of knowing for sure
Your datacenter is not like a cloud datacenter
6.9 million copies of “The Half Blood Prince” were
sold in the first 24 hours of release in the US
http://en.wikipedia.org/wiki/Harry_Potter#cite_note-bbc-hbp-record-95
Your datacenter is not like a cloud datacenter
If you were the online bookstore selling those 6.9 million copies would you
optimize for ACID or BASE consistency?
Your datacenter is not like a cloud datacenter
If you accidentally oversell by a few books, it’s OK to apologize
Your datacenter is not like a cloud datacenter
Flickr (http://highscalability.co
m/flickr-architecture)
Your datacenter is not like a cloud datacenter
Jim’s development team needs to think differently about app architecture in the
cloud, especially transactional state
Your datacenter is not like a cloud datacenter
“If my application is running in one of these massive datacenters, it’s not very “green” is
it?”

PUE: Power Usage Effectiveness
http://www.thegreengrid.org/Global/Content/white-papers/The-Green-Grid-Data-Center-Power-Efficiency-Metrics-PUE-and-DCiE
Green IT and Cloud Computing
The ratio of total energy consumption (servers + cooling) to 'useful' energy
consumption (servers only).
http://it.toolbox.com/wiki/index.php/Power_Usage_Effectiveness_%28PUE%29
Green IT and Cloud Computing
A typical enterprise-level data center is thought to have a PUE of 2.0 or greater
http://it.toolbox.com/wiki/index.php/Power_Usage_Effectiveness_%28PUE%29
Green IT and Cloud Computing
This means that for every watt of IT power, an additional watt is used to cool and distribute power to the IT
equipment
http://it.toolbox.com/wiki/index.php/Power_Usage_Effectiveness_%28PUE%29
Green IT and Cloud Computing
Our prediction is that the Chicago data center will deliver an average PUE of
1.22

Why is this important to him? He’s not running a cloud data center…
Green IT and Cloud Computing
True; but running applications in the cloud means that Jim “inherits” the
green profile (PUE) of that datacenter
Green IT and Cloud Computing
May be of little consequence now, but what happens in 5, 10, 15 years time when regulations get stricter about
PUE?
Green IT and Cloud Computing
Did you know that our industry accounts for 2% of the total carbon
emissions – the same as the aviation industry!
http://www.gartner.com/it/page.jsp?id=503867
Green IT and Cloud Computing
When that time comes does Jim want to be measuring his own PUE or inheriting from someone else?
Green IT and Cloud Computing
Fair point – good to know that you are on it

Talking about policy – what’s the deal with cloud computing when it comes to
regulations?
Policy and Regulations
Policy and Regulations
…especially having your data stored in datacenters located outside your own
country
Policy and Regulations
For example, would a non-US government entity trust data stored in a
US datacenter?

Would you trust your data to be stored in a datacenter not in your home
country?

This is high on the list of concerns for many thinking about moving to the
cloud…

This has been good things to consider so far, but Jim has one last question…
Identity in the Cloud
“…I have a great new idea that I want to try out in the cloud. Will it make me rich!?! :-)”
Show me the Money!!!
Show me the Money!!!
Consultant’s answer: Well, it depends…
Show me the Money!!!
One on hand, possibly…
Show me the Money!!!
On premises CRM system
Show me the Money!!!
$12 per month per user
Show me the Money!!!
Hardware, software, datacenter hoteling, management, operations,
helpdesk, etc.
Show me the Money!!!
Cloud based CRM software
Show me the Money!!!
$10 per month per user
Show me the Money!!!
Arguable $2 per user per month saving(not factoring in migration costs)
Show me the Money!!!
DELL PowerEdge M600 = $4,689
Show me the Money!!!
10 of those = $46,890
Show me the Money!!!
$0.30 per compute hour (High CPU)
Show me the Money!!!
The same $46,890 would buy you156,300 compute hours
Show me the Money!!!
651.25 compute days for 10 instances
Show me the Money!!!
21.4 compute months for 10 instances
Show me the Money!!!
Let’s not forget however…
Bandwidth is not free
Show me the Money!!!
Jim’s get-rich-quick idea is a new cloud based application for Blu-ray movies!
Show me the Money!!!
What’s this going to cost to run?
Show me the Money!!!
Internet Radio (64kps) 21Gb per month (24 hours per day)
Show me the Money!!!
YouTube (512kps)166Gb per month (24 hours per day)
Show me the Money!!!
HDTV (4Mbps)1296Gb per month (24 hours per day)
Show me the Money!!!
Storage - $0.15 per GbData Transfer - $0.17 per Gb
Show me the Money!!!
Sounds cheap, but is it?
Show me the Money!!!

What did Jim Learn?
When Jim was first looking into cloud computing, he wanted to take his VB6 application into the cloud
What did Jim Learn?
He now realizes that his VB6 application isn’t well architected for the cloud
What did Jim Learn?
