Embracing the Cloud(The Obvious)

• Provisioning Speedo Minutes, not weeks

o Autoscaling in response to load

• Near-Infinite Capacityo No need to predict and plan for growth

o No need to defensively overprovision

• Pay For What You Useo No “utilization risk” from owning / renting

o If it’s not in use, spin it down

Embracing the Cloud(The Less Obvious)

• Instance Optimization Opportunitieso Instance shapes to fit most parts of the solution space (compute-intensive, IO-

intensive, etc.)

o If the shape does not fit, try another

• Service Qualityo Amazon and Google know how to run data centers

o Battle-tested and highly automated

o World-class networking, both cluster fabric and external peering

So You Still Want Your Own Data Center …

• Unstoppable Economicso Can you buy hardware more cheaply than Amazon and Google?

o Can you operate the data center more efficiently than Amazon and Google?

o Can you achieve better resource utilization than Amazon and Google?

• Resilience to Breaches and Failureso Is your security team as practiced as Amazon’s and Google’s?

o Can your teams manage machine failure, disaster recovery, etc., like Amazon and Google?

• Global Footprinto Do you have the same global footprint of data centers, edge points of presence,

and peering relationships as Amazon and Google?

“But I Work at a Bank …”

• Banks are using public cloud todayo 3 top Australian banks (Suncorp, NAB, Commonwealth) use Amazon Web

Services today

o Netherlands banking authority has cleared public cloud for use by NL banks

o Many others piloting, evaluating, etc.

• Majority of computing at a bank is not “banking”o Not about talking to a financial exchange

o Not about regulated operations

The 2010s of computing are like the 1910s of electric power(!)

“Soon it will be just as common to run your own data center as it is to run your own electric power generation”
