An edge data center is a small data center that is located close to the edge of a network. It provides the same device found in traditional data centers but is contained in a smaller footprint, closer to end users and devices. Edge data centers can deliver cached content and cloud computing resources to these devices. The concept works off edge computing, which is a distributed IT architecture where client data is processed as close to the originating source as possible. Because the smaller data centers are positioned close to the end users, they are used to deliver fast services with minimal latency.
Many organizations see in-house data centers or hosted infrastructure as an either-or. However, colocation data centers provide a third option that splits the difference between the two. In a colocation data center, an organization is leasing space from a third-party provider similar to a cloud-based deployment model. However, unlike the cloud, the servers and network infrastructure used by a company are privately owned and operated by that company.
A hyperscale data center is big, not only in data capacity (hyperscale data centers typically house 5,000 or more servers) but also power consumption. A single hyperscale site can consume more than 50MW annually and there are estimates of global power consumption that approach 200 TeraWatt-hours annually.
Hyperscale facilities are really just supercharged outsourced data centers with virtually unlimited scalability. The ease in which new services can be deployed – for organizations of any size – is a major business benefit responsible for their growth and impact.
