The cloud also presents networking challenges for cloud providers:

An enterprise cannot directly connect its distributed sites to its cloud applications, having to, instead, backhaul all network traffic through its data center because it lacks a network-aware endpoint in the cloud.

An enterprise does not enjoy the same levels of privacy and security for its cloud deployment as it does for its premises.

An enterprise does not own its cloud connectivity, so it cannot extend its network configuration into the cloud.

However, the shared-infrastructure, shared-resource cloud environment poses networking and security problems for enterprises:

These external data centers, known as provider-hosted clouds, allow enterprises to gain infrastructure and resources on demand and become even more operationally efficient. Many enterprises have started deploying IT applications in virtualized data centers that are built and managed by third-party service providers. To save costs and become more agile, businesses small and large are increasingly virtualizing their data center infrastructures and applications.
