In 2019, 51 percent of North American network professionals surveyed by IHS Markit say they will use hybrid cloud. Some 37 percent will adopt multi-cloud for application delivery.
Enterprise IT architectures and consumption models are changing, from servers and applications placed at individual enterprise sites, to a hybrid-cloud model where centralized infrastructure-as-a-service (IaaS) complements highly utilized servers in enterprise-operated data centers, IHS Markit says.
Respondents also suggested that hybrid cloud is a stepping stone to multi-cloud.
Over time, certain functions requiring low latency will migrate back to the enterprise edge, residing on universal customer premises equipment (uCPE) and other shared compute platforms. This development is still in its infancy, though.
Performance is a top concern, and enterprises are not only adding more WAN capacity and redundancy, but also adopting SD-WAN, IHS Markit says. The primary motivation for deploying SD-WAN is to improve application performance and simplify WAN management.
Bandwidth consumption continues to rise. Companies are expecting to increase provisioned wide-area network (WAN) bandwidth by more than 30 percent annually across all site types.
Data backup and storage is the leading reason for traffic growth, followed by cloud services.
