CoreSite Realty Corporation (NYSE: COR), a national provider of powerful, network-rich data centers, today announced the availability of Amazon Web Services (AWS) Direct Connect in CoreSite’s New York data center. AWS Direct Connect’s first presence in New York supports the growing customer demand for the AWS cloud, improving service to digital content communities, financial services organizations, and managed service providers. Through AWS Direct Connect, CoreSite customers can directly access AWS cloud services over a secure private-network connection. The benefits of this direct access include reduced network costs, increased scalability for throughput and more consistent network performance. Additional benefits include reduced bandwidth costs and increased bandwidth capacity. CoreSite currently offers AWS Direct Connect at its Los Angeles campus, where CoreSite customers have been using the service since late 2011. AWS, one of the world’s largest cloud service providers, makes it easy for CoreSite customers to establish a dedicated network connection from their locations to AWS, avoiding the need to access the public cloud over the internet. Customers see improved application performance through more consistent network performance and enhanced security features for transport of digital content. CoreSite customers can access AWS Direct Connect via a standard, single-mode fiber 1 Gbps or 10 Gbps Ethernet cross connection or Any2 internet exchange connection, ordered via the MyCoreSite online customer portal. “CoreSite is pleased to be the first data center provider in the New York metro region to provide direct, on-site access to one of the world’s largest cloud offerings in Amazon Web Services,” commented Jarrett Appleby, COO of CoreSite. “CoreSite’s cloud computing data center ecosystems and collaboration with Amazon demonstrate CoreSite’s strong growth in this ecosystem and increased value to our customer base, with access to cloud offerings of all sizes only a simple cross connect away.” For more information on AWS Direct Connect accessible at CoreSite’s New York data center, please visit www.CoreSite.com/Amazon-Web-Services-Direct-Connect.php.
