NetFoundry announced the findings of a new survey of 200 IT managers discussing applications networking, security and the cloud.The shift of applications from on premises applications to hybrid-cloud environments has posed myraid challenges to IT departments who need to efficiently and securely connect applications. To gain insight into these challenges, the research firm Futuriom surveyed 200 IT managers in application development, networking, security and DevOps and reached some major conclusions in a new report.
Conclusions of the research, based on survey data and primary research with enterprise end users, include the following: Virtual Private Networks (VPNs) are seen as having significant security and performance drawbacks for use in networking cloud applications.

- 63.5% of users survey cited issues with VPN performance
- 47.5% cited issues with security
- 75% of VPN users said they are seeking a better solution for cloud networks

SD WAN Not Making Grade for Industrial IoT
SD-WAN may be a highly deployed enterprise WAN and branch office solution for enteprise site connectivity, but it’s not seen as an Industrial IoT solution. It’s important to understand the relationship among legacy networks using private circuits such as MPLS, the next-generation architecture known as SD-WAN, VPNs, and additional potential solutions for cloud network.
While some respondents believe that MPLS/SD-WAN can be used to network cloud applications, it’s clear that there is the desire for additional layers of security and virtualization. The view on using MPLS for cloud applications is split down the middle. 45.5% of the respondents agreed that carrier-delivered MPLS wasn’t the right solution for cloud-based networking, while 46% disagreed with that statement. This indicates that conviction is lacking in MPLS and that many IT managers believe additional technology is needed for networking cloud applications.
A key area of concern about MPLS is security. This is because MPLS does not have full security baked into the service, and requires additional measures, according to our respondents. 73.5% of the respondents said they run an additional layer of security over MPLS.

- 74.5% said they see hardware root-of-trust as a significant security feature.
- When asked if Zero Trust network architectures are a significant improvement in networking security, 55.5% agreed this was true, while only 15% disagreed. 29.5% said they don't know.
- Users don’t see private lines or MPLS as fully secure networking solutions for cloud applications. Most respondents today use an additional security overlay.

Internet of Things (IoT) technology is viewed as an outlier in the world of secure networking. Several high-profile hacks of IoT devices, including surveillance cameras and automobiles, has led to security concern about IoT devices. End-user research, including survey from the data and end-users interviews, backs this up. Survey respondents do not view VPNs as suitable for IoT security, nor do they see SD-WAN technology as a panacea. Respondents did identify such as hardware root of trust and Zero Trust networks as potential security solutions.

ASNs to the Rescue
Application Specific Networks (ASNs) provide the answer as an alternative to VPNs and MPLS, and an improved and secure architecture for the IIoT, especially as a majority of end users are seeking zero-trust networks and hardware root of trust for network security.
An ASN is a software-only network that connects applications without requiring management of hardware devices, operating systems, or servers. Unlike VPNs, ASNs can be provisioned automatically by the applications in the cloud.

ASN Key features
- Secure networking tied to applications, not devices.
- Applications-based networking that is easy to set up and tear down with software
- No “box management” necessary to instantiate a network
- Networking and security features targeted at DevOps and software development staff

Views on MPLS and SD-WAN
ASNs design incorporate a new architectural design of creating of logical networks across the Internet and WAN to connect applications — we call these AppWANs. The AppWANs are the glue that can securely connect parts of a distributed application, which often includes connecting applications programming interfaces (APIs) and workloads that may run across clouds. An AppWAN can connect an endpoint or resource in the cloud that need to be connected securely and efficiently.  It can be used to replace legacy technologies like VPNs and MPLS, which are tied to specific hardware devices but aren’t nearly as flexible.
“Based on the end-user feedback of our Application Networking Survey, IT managers  are looking for a more flexible and secure software-based networking solution for the cloud,” said Scott Raynovich, founding analyst for Futorium.“ASNs are likely to serve that person to connect distributed applications in SaaS, IaaS, and PaaS environments, whether it’s single cloud, hybrid cloud, and multi-cloud environments.”

Survey Methodology
Futuriom used an online survey tool to reach 200 IT staff balanced over applications development, networking, security, and DevOps functions. The survey used screening questions to assure only the results from IT staff.
