2. Flexibility
Agility
Speed to Market
Stack Commoditisation (Hi, Simon )
Simplification
Consolidation
Step 1 – Why do it
Improved Scalability
Better Utilisation
Remove rarely used
overheads
Social Responsibility
Carbon Reduction
Operational Cost Reduction

3. Review your product portfolio
Find suitable application or services
Review Risk
Security, SLAs
Step 2 – What to move into the
Cloud
Tech Team to review suitability
Not every application is suitable ... yet, i.e. heavy DB apps
Check Licensing!!!!!!
Can be challenging– sockets, cores, instances, users,
You need per hour pricing or elasticity goes out the window!!

4. PaaS e.g. Force.com, Google App Engine
IaaS/HaaS e.g. Amazon EC2, GoGrid
Step 3 – The Level
SaaS e.g. Salesforce.com, Netsuite

5. Public Cloud
Federated Cloud
Step 4 – Type of Cloud
Private Cloud
Shared Private Cloud

6. Virtual Private Data Centre (VPDC)
Step 5 – Data Centre Automation OR
Federation Management
• End-to-end Provisioning
• Automated Hardware orchestration
• Full self-service
• Usage based billing
• Asset or Identity Management
• Multi-tenancy
• Monitoring

7. Network Fabric is key!!!
Impacts Scalability
Storage will be 80% of your problems
Step 6 – HW decisions
Commodity kit vs. HW appliances
Load Balancers, Firewalls, IDS
Type of servers
Cores, power usage, pizza box vs. redundant box, memory

8. Your mid-level Mgmt will be against it!!
Fear of losing control, job, ....
Commoditisation, consolidation – expect major
pushback – THIS WON’T WORK HERE!!!
Humans don’t like change!
Step 7 – Staffing Considerations
75% of your staff looking after the lower
HW/SW stack will be redundant in 3-5 years!
HW folks, staging, installation, provisioning, etc.
You need to start planning NOW what you will do with those people

9. SLAs
Mostly marketing driven, e.g. Amazon EC2
Security Concerns
Step 8 – Consider challenges
QoS
Simply missing!!!
Interoperability & standards
APIs, images, data formats, billing
