TCTS Cloud Networking as a Service (CNaaS)

Published on: November 18, 2019 |  Author : Vineet Anshuman


The worldwide public cloud services market is projected to grow 17.5 percent in 2019 to total $214.3 billion, up from $182.4 billion in 2018, according to Gartner, Inc. As most enterprises and small businesses gravitate to the cloud, the boundaries between the enterprise and the cloud continues to blur. Hybrid and multi-clouds continues to be the strategy with most CIOs as regulatory, data governance, security and performance guarantees, etc continue to slow the migration to an all-cloud strategy (Please see diagram below) . To add to this, public cloud management and configuration continues to get more complex. The growing cloud computing complexity was recently documented by the Wall Street Journal that cites a survey of 46 CIOs by KeyBanc Capital Markets. Companies this year are expected to spend more on IT, particularly cloud and security, as they manage increasingly complex technology environments that include a mix of cloud providers as well as on-premise infrastructure.

As cloud complexity continues to grow, enterprises are grappling with the many functions, gateways, configuration, segmentation and monitoring of Virtual Networks (VNets) or Virtual Private Clouds (VPCs) across data centers, regions and worldwide deployments. Configuration of routing tables, security, gateways and hybrid connectivity within a public cloud VNet/VPC continues to be a problem area for most enterprises. Additionally as the cloud expands to the edge, including managed network connections between cloud and service providers (ie: Express Route, Direct Connect, etc), cloud complexity will be even more challenging to configure and operate. This can be best represented in the diagram below that depicts native cloud functions deployed and distributed throughout the various regions and subnets for a given enterprise VNet/VPC.
