Cloud Services

The world is hybrid. With the increased adoption of public cloud services, businesses deploy a mix of IT services across public cloud providers, own data centers or leverage providers such as CyrusOne to gain flexible access to additional data-center capacity for their private cloud requirements. Where the business chooses to deploy the IT services differs greatly depending on business, regulatory and security needs, and leads to a requirement to be able to support the entire “Cloud Continuum.”
