With the migration of applications to the cloud, the need for secure, scalable and easy-to-manage connections to them is an increasing reality. To date, connectivity providers have taken the following approaches to building their connections to the world’s largest cloud service providers:
Direct End-to-End
These cloud connections are built by the carrier to offer private connectivity from the customer’s LAN to every cloud service provider the carrier reaches – typically the largest cloud service providers in the world – entirely over that single carrier’s private network. These connections are built out directly into the data centers of these global cloud service providers, meaning no third-party network is utilized. This is the fastest, most secure, and easiest to manage connection to the cloud.

Verizon Secure Cloud Interconnect Secure Cloud Interconnect (SCI) can connect any business to the cloud service providers Verizon has connected with. Verizon customers can utilize a private node to access the SCI platform that links them directly to the CSPs. Non-Verizon customers can either use their Internet connection to access Verizon’s SCI (although that negates the private end-to-end connection) or have one private Verizon node added to their network to then privately access SCI. Connections: AWS, Microsoft Azure, Google, HPE, IBM, Oracle, Salesforce |

Hybrid Direct & Equinix Cloud Exchange
These cloud connections utilize a mixture of direct connections to some cloud service providers and link to Equinix’s Cloud Exchange to access others. Customers will purchase a connection from one of the below carriers and, depending on the cloud service provider they want to reach, will either utilize that carrier’s direct end-to-end connection or be routed over the Equinix Cloud Exchange by that carrier.
Using the Equinix Cloud Exchange requires a cross connect from the carrier to the Cloud Exchange within an Equinix data center – this means that data traffic is now traversing a separate network to reach the desired cloud service provider. Equinix’s Cloud Exchange network is far-reaching and reliable, but it is important to note for customers that not all cloud service providers will be reached with a direct end-to-end connection by the carrier.

Equinix Cloud Exchange
These cloud connections use carrier networks to connect the customer’s LAN to the Equinix Cloud Exchange within Equinix data centers. The Equinix Cloud Exchange then connects customers to cloud service providers in both domestic and international markets. Using the Equinix Cloud Exchange requires a cross connect from the carrier to the Cloud Exchange within an Equinix data center – this means that data traffic is now traversing a separate network to reach the desired cloud service provider. Equinix’s Cloud Exchange network is far-reaching and reliable, but it is important to note for customers that cloud service providers will not be reached with a direct end-to-end connection by the carrier.
