Globally Integrated

Build globally seamless hybrid cloud systems that span locations with our highly scalable, enterprise-class, Enterprise Cloud service. Enterprise Cloud combines hosted private, public, multi-tenant and third-party cloud infrastructures. Clouds can connect at Layer 2, using highly-secure software-defined networking (SDN) technology, and integrate with your on-premises infrastructure, creating a true hybrid cloud. This gives you the flexibility to locate compute resources close to important markets, or if data sovereignty is important, restrict deployment to your host country.

Enterprise Cloud is built on the foundation of our global VPN and IP backbone networks and our global premiere data centers. We offer a free, direct connection to our closed network and 10Gbps connectivity between global data centers and the cloud.


Cloud Migration

Our Enterprise Cloud solution is supported by advisory, migration, operations and management services to help you quickly deploy the most functional cloud infrastructure tailored to the specific needs of your business.

Enterprise Cloud hosted private cloud offers on-demand bare metal servers, multi-hypervisors (VMware vSphere, Microsoft Hyper-V) and agile network mapping to precisely reflect your on-premises network topology and configuration on our cloud service.


Enterprise Cloud supports rapid business innovation with a multi-tenant public cloud built on Openstack, the open-source cloud ecosystem. The platform is ideal for cloud-native agile development and DevOps, and incorporates Cloud Foundry platform-as-a-service (PaaS) for creating virtual private PaaS. Public clouds can connect securely to hosted private clouds and third-party clouds using SDN-enabled networking.

Cloud Management

Our Cloud Management Platform (CMP) offers efficient management, operational governance and orchestration of Enterprise Cloud and third-party cloud solutions. With CMP, you gain visibility into the full IT stack, including shadow IT, enabling greater control of traditional ICT and cloud-native ICT infrastructures. CMP provides cloud discovery and orchestration tools for use across all cloud platforms (on-premises, hosted private, bare metal, public and third-party, including Amazon Web Services (AWS) and Microsoft Azure).
