Data Center Interconnect (DCI) refers to the networking of two or more different data centers to achieve business or IT objectives. This interconnectivity between separate data centers enables them to work together, share resources and/or pass workloads between one another.
A data center interconnect is mainly accomplished using networking tools and techniques along with supported software and data center management processes.
Data center interconnect is a technique used in enterprise IT infrastructures that have multiple owned or partnered data centers. Typically, data center interconnect is achieved by connecting data centers through a VPN, leased lines or the Internet. Once connected, these data centers can use all or selected IT resources from within the network.
Some of the ways data center interconnect is used are:
- To connect multiple data centers within the same organization
- To connect partner/customer data centers with shared data and/or resources
- To allow for workload sharing, wherein some or the bulk of the processes are performed at the interconnected data center
- To pool data center resources to meet scalability needs
- To use an interconnected data center as a disaster recovery site
