The continued growth of Internet of Things (IoT), the rising volume of digital traffic, and the increasing adoption of cloud-based applications are key technology trends that are changing the landscape of data centers.
Large or extra-large cloud data centers now house many of the critical applications for enterprise businesses that once resided in their on-premise data centers. Not all applications have shifted to the cloud, however, and the reasons are varied – including regulations, company culture, proprietary applications, and latency – just to name a few.
As a result, we’re left with what we refer to in this paper as a “hybrid data center environment”.
That is, an environment consisting of a mix of (1) centralized cloud data centers, (2) regional medium to large data centers, and (3) localized, smaller, onpremise data centers. What once was a 1MW data center on-premise at an enterprise branch location may now consist of a couple of racks of IT equipment running critical applications and/or providing the network connectivity to the cloud. The decreased footprint and capacity of the on-premise data center should not be equated to being lower in criticality. In fact, in many cases, what’s left on-premise becomes more important.
