TDM are...

Happy Penguins!
...because we believe there is:

• An ethical case
• A technological case and
• A rock solid business case

...for Open Source software.

TDM are not...

Angry Penguins
...because we believe that:

• We should seek to use good
software wherever it helps.
• Proprietary software can
serve as the Ying to Open
Source's Yang.


Who are we?


http://tdm.info


We are going to...
• Talk about when / why to choose cloud computing

• Get you talking about when you personally might
choose cloud computing

• Show you some ways in which we are using cloud
computing ourselves

...so let's get started.


How many people here
use Linux on a daily basis?


How many people here
use the internet on a use
How many people here daily
the internet on a daily basis?
basis?


Five different ways we can compute
1. Local Device e.g. Desktop, Laptop, Netbook, PDA, Games Console, Watch(?), Fridge(?)

2. Local Server e.g. Dell or IBM running Windows or Linux

3. Single SaaS (Software as a Service) e.g. SalesForce.com

4. Open Cloud e.g. TDM, ULCC

5. Corporate Cloud e.g. Windows Azure, Google Apps, Amazon EC2

= Choice with Trade-offs


(1) Your own Local Device
Positives Negatives
• You can work on the train! • Poor for Community
(No Broadband Required) Interaction / Collaboration
• High Performance • Disincentive for corporate
• “Tailorability” interoperability
• Very private, locally stored
data
• Mobile augmented reality


(2) Local Servers Managed by IT
Dept.
Positives Negatives
• Some Privacy but more • Not very eco-friendly
interactivity
• Core versus fringe activity.
• Easy to monitor security
and performance e.g. Would an FE College
employ a construction
• Easy to monitor user department with and architect,
activity (re: Data Protection civili engineer, construction
+ e-Safety) worker etc.?

• Very private, locally stored
data

What is this?


Local Electricity Generators were made
redundant by the National Grid...


(3) Open Cloud / Shared Services / Open
Source Software, Elastic Computing
Positives Negatives
• Eco-friendly - effectively • Trust: Perhaps it is easier to
managed server space in trust Microsoft?
datacentres (VMs?)
• Price: More expensive than
• Still get local access to international data centre
expertise / support hosting?
• Outsource supplier will offer
training / configuration services
in addition to managed hosting
• Rapid Deployment / ease of
scaling


(4) (Single) SaaS
Twitter v's identi.ca / FaceBook versus Mahoodle (Creepy Treehouse)

Positives Negatives
• Big communities can boom • Privacy? Ownership of Data
better than (eg TDM (eg Facebook)
Network Hubs)
• Exportability? If the service
• Marketing: You go out to goes down, you lose
the people (they don't come everything (eg Pod-O-Matic)
to you).
• Misuse? Creepy Treehouse -
• Very private, locally stored Ref: e-Learning?
data


(4) Open Cloud
 Hosted Services e.g. VMs, Dedicated servers (eg Rackspace),
Co-Located Servers
 Managed Services e.g. TDM, Rackspace

(5) Corporate Cloud
 Hosted Services e.g. Old-Style Webhosting (on templates and
cPanels) or Amazon EC2
 Managed Services e.g. Windows Azure, Google Apps, Sales
Force.com


(5) Corporate Cloud: International
Datacenters


(5) Corporate Cloud: International
Datacenters
Positives Negatives
• Green and Eco-Friendly • Trust?
• Rapid Deployment • Privacy Policy?
• Easy Scalability • Exportability of your Data?
• Professional Support • Openness of APIs?
Software Integration?
• Control over future costs?
• Configurability of platform?


This is an age of
Technopreneurship,
Choices
and Trade-offs
