Virtual Private Clouds (VPC) Combine the Characteristics of Cloud Services and Enterprise Networking
Buying experience: user self-service under an enterprise umbrella
Feature set: flexibility to support diverse workloads across the enterprise
Use cases: complement or extend existing IT operation, not replacement
Governance framework: identity, access, roles, hierarchy, auditability
Networking: performance, security and simplicity of on-net access
Enterprise IT buyers seek to combine the security and performance of private cloud with the economics and flexibility of public cloud
