The problem:
equipment provisioning
• Your service demand vary during time
according to external events (e.g. sport
matches, holidays)
• You size your infrastructure to ensure
performance during peak load
• Part of your equipment sits idle most of the
time (off peak)

Solution:
on demand provisioning
• You size your infrastructure to ensure
performance for the average load
• The cloud absorbs peaks in load
• You pay only for the resources you use

Benefits of the cloud
• On demand scalability
• Fixed cost reduction
• Pay per use
• Testbed for research and development
• Consistent performance at a lower cost

Drawbacks of the cloud
• Increased architecture complexity
• Less control on cloud resources
• Data security implications
