terconnections can have capacity of 10 to 100 Gbps. The fact that the data is in the cloud or at a hosting www.TechnicalPDF.com center is seamless to end users because there are minimal delays. In this way they emulate connections within the building to internal data centers in the same organization. To ensure low latency, close to continuous uptime, and low mean time to repair problems, many companies sign a Service Level Agreement (SLA) with commitments from their interconnection provider, specifying the percent of uptime, mean time to repair, and the amount of latency in accessing the cloud. If the SLA conditions are not met, the customer has the option of discontinuing the service without a monetary penalty. An additional option on dedicated interconnections is to bond multiple Gigabit Ethernet trunks together to double or triple the connection capacity. For example, Google supports bonding of up to eight connections to reach its services. Amazon Web Services, Microsoft Azure, Oracle, and, Equinix all support direct, private interconnections to organizations' cloud-based applications on their hosting and cloud data centers. Equinix and Coresite provide a service whereby multi-location enterprises connect to Equinix or Coresite from their main location. They both in turn connect enterprises to each of the cloud sites at which their applications are located. See Figure 5-9 for an example of direct interconnection to multiple clouds. This obviates the requirement for a separate connection directly to each provider's site. In addition to minimizing latency (delays in getting responses to queries), direct dedicated connections provide more security and privacy than do Internet connections to cloud and hosting sites. www.TechnicalPDF.com Enterprise needs only a single link (plus a backup link) for direct interconnections to organizations servers at multiple cloud providers Amazon Web Salesforce.com Equinix or Coresite Microsoft Azure Oracle Cloud Services ******** Enterprise hub at interconnection data center Backu
