They are evaluating the feasibility of obtaining another data center in a remote location to enable further growth.
One of the web hosting company's eCommerce customers notifies them that they are launching an enormous holiday sale, beginning in a few weeks. They expect utilization of their virtual server farm to double or triple for the next three to six months. The web hosting company cannot deploy the needed resources in a new data center in time for the sale. They opt to purchase services from a cloud service provider using a pay-as-you-go model.
Over the next two weeks, Layer 2 connectivity is established between the two sites. The web hosting company's IT staff works with the CSP to configure the necessary physical and virtual infrastructure. All traffic to the public cloud is routed through the private data center, across the Layer 2 connection. A local load balancer is deployed in the private data center. Orchestration tools are configured to burst the service into the public cloud automatically when utilization reaches 80%."
