Mike Lossman, Technical Product Marketing Manager at Forward Networks, shares his insights on digital twins—mathematically accurate copies of data center networks. He details how these models revolutionize network operations by enabling real-time visibility, automation, and enhanced troubleshooting. Lossman also discusses the challenges of IT infrastructure during mergers and acquisitions and highlights the importance of a network query engine for compliance and multi-vendor support, ensuring efficient network management.
Digital twins provide a dynamic, mathematically accurate representation of networks, enhancing visibility and objective troubleshooting for network professionals.
By simulating changes within a controlled environment, digital twins allow engineers to assess potential impacts on network connectivity without disrupting live operations.
The integration of digital twins with IT management tools democratizes network insights, empowering cross-functional teams to proactively address dependencies and minimize interruptions.
Deep dives
Understanding Digital Twins
A digital twin is defined as a mathematical model that provides a real-time, accurate reflection of an organization's network, both on-premises and in the cloud. Unlike traditional network diagrams that are static and unable to provide insights into the current state of the network, digital twins utilize complex algorithms to analyze network configurations and state to deliver a dynamic representation. This eliminates the guesswork involved in navigating network environments, allowing engineers to objectively diagnose issues and understand the flow of traffic without any physical packets traversing the network. As such, a digital twin transforms the way network professionals interact with their environments, providing them with a comprehensive understanding devoid of the limitations of legacy mapping tools.
Features of Digital Twins vs. Infrastructure as Code
While infrastructure as code (IAC) focuses on managing network configurations, digital twins offer a deeper insight into the actual path traffic takes through a network. Digital twins enable troubleshooting by allowing engineers to simulate changes without modifying the live environment, allowing for what-if scenarios. For instance, they can temporarily disable firewalls in a controlled setting to assess how changes will impact connectivity across the network. As a read-only platform, digital twins provide a seamless way to visualize potential issues and their resolutions without risking disruption to ongoing operations.
Integration and Monitoring Capabilities
Digital twins serve as a source of truth for network infrastructure, integrating seamlessly with IT management tools such as NetBox and ServiceNow to ensure accurate inventory management. The platform can not only identify devices within the network but also keep track of any newly added resources by running consistent checks against the confirmed inventory. In addition, it allows for snapshotting network states, which can then be compared before and after changes to determine whether configurations meet specified criteria. These monitoring capabilities help operations teams perform extensive audits while ensuring compliance with standards like STIGs and uncovering potential vulnerabilities proactively.
Change Management and Troubleshooting Support
The use of digital twins facilitates a structured change management process by enabling network engineers to execute and verify changes with higher confidence. By taking snapshots before and after changes are implemented, engineers can compare configurations and identify discrepancies that may indicate issues. Additionally, the platform can monitor the broader impact of changes across the entire network, alerting teams to potential problems as they arise. This capability greatly reduces the risks associated with complex change processes that, if mishandled, could lead to significant operational disruptions.
Collaboration and Access for Cross-Functional Teams
Digital twins are not only beneficial for network engineers but also empower cross-functional teams such as SecOps and application developers to enhance their understanding of the network. By granting access to the digital twin platform, non-network personnel can run their own queries and discover potential roadblocks or dependencies without solely relying on network teams. This democratization of network insights minimizes interruptions by allowing other stakeholders to proactively address their concerns and facilitates better communication between teams. Ultimately, this collaborative approach fosters a more agile environment where all teams can contribute to maintaining optimal network functionality.
