But there are “considerations” Link issues

DATA CENTER CLOUD
DATA CENTER VERSUS EDGE CLOUD
• Centralized
EDGE CLOUD
• Economies of scale
• Cheap space and energy
• A/C often not required
• Commoditized repeatable HW & SW
• Homogeneous management
• Not sensitive to latency
• Close to customers• Economies of application
• Premium for space and energy
• A/C required
• Tailored HW & SW
• Tailored management
• Low latency required

vCPE needs cleartext to process data
However the medium between the CP and cloud is unprotected
Hence both user encryption and tunnel encryption is required
Doubles processing and energy costs

choice for some applications However it has its unique
economics and scale Thus it needs tailored
solution Some things to consider:
B NFV at the network edgeB NFV accelerationB Hyper-converged cloud
