Latency is associated with reliability and can dictate whether a workload can be moved to the cloud. While most of the applications accessed over the public internet are SaaS solutions, some companies were accessing their own services hosted by cloud providers. Most companies had not fully considered reducing latency by utilising direct connection (Cloud Connect) to their cloud platforms and hybrid solutions.
VPNs are quick and simple to deploy and can encompass remote sites and users as well as the main corporate location connecting through encrypted tunnels to the cloud infrastructure, or connecting two separate cloud platforms. 39% use a VPN over the public Internet. Nearly a third use the public internet without a VPN. This is mainly being used for cloud based applications such as Salesforce.com CRM rather than accessing corporate infrastructures.
The use of the public internet could also be the cause for some of the reported concerns regarding the security of the cloud and latency. 28% use direct connections such as Microsoft Azure Express Route and AWS Direct Connect. Direct connections provide a more secure solution to cloud access and can deliver lower latency. Often direct connections are perceived as more complex to set up and less flexible than VPNs, however, this is no longer the case and they can also offer higher bandwidth for a lower cost. The direct connection use will grow as more companies understand the technical, operational and cost benefits.
