Public Clouds Burst with VPC Benefits.

When private cloud computing takes places within a provider's public cloud infrastructure, the result is a virtual private cloud. By isolating a specific segment of their public cloud, providers can offer individual, on-demand access to clients. Companies who subscribe to VPC realize benefits from maintaining control without having to share resources with other clients. 

How Business Benefits from the VPC

The virtual private cloud (VPC) results from logically dividing a service provider's public cloud. The service provides the architecture to support the computing of multiple subscribers in their private cloud. When organizations use a VPC, a public cloud service becomes the provider, and the subscribers become tenants. This feature allows a business to benefit in the following ways:

• Granular control over virtual networks.
• Isolated environment for sensitive workloads. 
• Access to off-premise, scalable public cloud resources.
• Pay-as-you-go options.
• Direct management of network components: IP addresses, subnets, network gateways, and policies regarding access control.

Security Features

When using public cloud services, companies must depend on encryption technology to protect transmissions traveling across the web. While encryption is typically safe, it must be monitored and configured by corporate IT. Additionally, prevent the threat of unauthorized users. 

Benefits of VPC storage allows companies with routing policy's in place to specify exactly who is allowed access to the resources contained in the cloud and who is not. The traffic to, and returning from the cloud remains in the corporate firewall, separated from the internet.

Hybrid Cloud Deployment

Organizations benefit from VPC due to the flexibility offered by hybrid cloud deployment. Workloads freely move back and forth between the VPC and the public cloud as costs fluctuate and computing needs change. Hybrid clouds give businesses increased data deployment choices and more overall flexibility.
