Expand Your Infrastructure to the Cloud: How It Works (Graphic: Business Wire)

DENVER--()--CoreSite Realty Corporation (NYSE:COR), a premier provider of secure, reliable, high-performance data center and interconnection solutions across the U.S., continues to improve the blueprint for seamless interoperability between on-premises VMware and VMware Cloud on AWS. VMware Cloud on AWS brings together VMware’s enterprise-class Software-Defined Data Center (SDDC) software and elastic, bare-metal infrastructure from Amazon Web Services (AWS) to provide organizations with a consistent operating model and application mobility across private and public cloud resources. Direct connectivity to VMware Cloud on AWS is available through CoreSite’s Data Center fiber interconnections or through the CoreSite Open Cloud Exchange in four CoreSite markets, including Boston, Denver, New York and Northern Virginia.

With over 66% of all enterprises having VMware installed on-premise, an adjacent hybrid cloud architecture can benefit these organizations by providing seamless interoperability between on-premises VMware and VMware Cloud on AWS environments allowing them to overcome some of the cloud adoption barriers they face today.
