Public cloud architecture
Equinix offers reference architectures to help companies explore their options for connecting to public clouds. Developed by experts from the Equinix Professional Services team, our cloud connectivity architectures have been tested and refined in Equinix Solution Validation Centers™.
Private access to public cloud providers
The most common architecture for direct connection, shown here, establishes private access to public cloud providers such as Amazon Web Services (AWS) and Microsoft Azure through extension nodes of customers' enterprise networks in Equinix data centres. These extension nodes, depicted as an Equinix Performance Hub™ in the reference diagram, connect to AWS services via AWS Direct Connect and to Azure services via Azure ExpressRoute. While only AWS and Azure are shown in the reference diagram, many other IaaS, PaaS and managed service providers are available for direct connection through our IBX facilities.
To tie data services back to corporate data centres—essential for data synchronisation and backup—the IBX facility is tethered to corporate and branch offices via Metro-Ethernet or other high-speed local loop lines. Metro-Ethernet usually provides higher, more consistent data throughput rates than IP networks.
