Replacing Legacy DDI with Hybrid SD-IPAM:

FusionLayer Introduces Cloud-Native Blueprint for DDI

HELSINKI — November 25, 2019— FusionLayer announced today that it has published a new reference architecture for replacing legacy DNS, DHCP, and IPAM (DDI) solutions, utilized by enterprises around the world. This cloud-native based blueprint has been released with a structured migration plan, designed to mitigate against business continuity threats organizations expect to face when moving away from legacy DDI solutions. Ready for the multi-cloud world, the patented FusionLayer solution eliminates network downtime in hybrid enterprise networks that can cost enterprises millions. 

Hybrid enterprise networking popularity has led to an increased usage of public cloud services, such as Amazon Web Service's Virtual Private Cloud (AWS VPC) and Microsoft’s Azure Virtual Network (VNET). Nonetheless, enterprises continue to base their IP and network assignment processes on legacy DNS, DHCP, and IPAM (DDI) solutions. These solutions are usually disconnected from the modern hybrid multi-cloud business infrastructure, leading to manual steps in network management that are both error-prone and potentially very expensive.

“According to Gartner research, the cost of network downtime for enterprises averages 5,600 US dollars per minute,” said Juha Holkkola, the Co-Founder and Chief Executive of FusionLayer. “Even so, most CIOs and IT executives continue to view the cost of manual processes in terms of man-hours and Operating Expenses. Our research shows that network downtime caused by human error and outdated processes are by far the most expensive mistakes large IT organizations make. For an organization managing thousands of networks, just one minute of downtime per network per year would cost millions.”

Legacy DDI solutions are commonly viewed as a mission-critical part of enterprise networks, and replacing them is often viewed as a risky endeavor, due to the potential of causing business continuity issues. These solutions typically date back to the 00s and lack integration possibilities. With digital transformation's introduction of new Information Technology models such as hybrid and edge clouds, traditional DDI solutions are unable to keep up with the evolution.

“When it comes to legacy DDI, you are damned if you do – and damned if you don’t,” continued Holkkola. “Conservative organizations would love nothing better than to stick with their old guns. The fact is, that in a cloud-native world this prudency has repercussions. When an enterprise WAN is extended into VPCs or VNETs with no solution or process in place to prevent overlap between them, an honest human error can quickly spiral out of control.”

The patented reference architecture released by FusionLayer aims to close the gap between the legacy business infrastructure and the cloud-native world, allowing all networks to be managed under a single umbrella. By organizing the management of all AWS VPCs, Azure VNETs, and tenant networks from both the edge cloud and traditional networks into FusionLayer’s unified overlay, the enforcement of standardized processes for the entire enterprise network can be enabled. And in turn, delivering the required level of network visibility and agility for the cloud-native world.

The FusionLayer reference architecture document, including a universal migration plan from existing DDI solutions, is available immediately for public download here.
