3. Cloud Computing Patterns
On and Off
On & off workloads (e.g. batch job)
Over provisioned capacity is wasted
Time to market can be cumbersome
Cloud Computing Patterns
Inactivity
Period
Compute t
Growing Fast
Successful services needs to grow/scale
Keeping up w/ growth is big IT challenge
Cannot provision hardware fast enough
Compute t
Unpredictable Bursting
Unexpected/unplanned peak in demand
Sudden spike impacts performance
Can’t over provision for extreme cases
Compute t
Predictable Bursting
Services with micro seasonality trends
Peaks due to periodic increased demand
IT complexity and wasted capacity
