- Flexible pricing options
- Cons
- total cost of ownership (TCO) can rise exponentially for large scale usage
- lease secure
- low visibility and control into the infrastructure
Vendor Responsibility
responsible for developing, managing, and maintaining the pool of computing resources shared between multiple tenants from across the network.
Private Cloud
Service Features
- Pros
- Dedicated and secure environments
- Customizable & Flexible
- high performance
- Cons
- high price for short-term use cases

Vendor Responsibility
Hybrid Cloud
Service Features
- Pros
- Flexible policy to deploy workloads on public or private infrastructure (based on security, performance and cost)
- scale with security (public cloud resources to accommodate occasional spikes)
- reliable (multiple data centers – public and private)
- cost control (sensitive workloads on private clouds, regular workloads on public cloud)
- Cons
- toggling between public and private (how to track, what’s the cost)
- public cloud resource management (different locations and categories)
- complexity of managing an evolving mix of private and public cloud architecture
