A recent study suggests that the next three years will see the vast majority (83%) of data center traffic migrate to the cloud. Additionally, this migration will take place through public cloud services and more workloads will exist in the public cloud than there are in private clouds (56 to 44%, respectively).
Roughly 65% of data center traffic exists in the cloud currently.
According to analysts for the study, “[s]ome enterprises might adopt a hybrid approach to cloud. In a hybrid cloud environment, some of the cloud computing resources are managed in-house by an enterprise and some are provided by an external provider.” The analysists also conclude that some of the ‘mission-critical workloads might continue to be retained in the traditional data centers or private cloud.”
More than likely, applications will be amongst the majority of cloud services and SaaS will still stand as the dominant mode. Right now, SaaS makes up 45% of implementations within the cloud, with IaaS and PaaS making up 42 and 13 percent, respectively. If these trends stay steady, experts suggest that these numbers will grow to 59% (SaaS), 28% (IaaS) and 11% (PaaS).
