You will often hear the comment that the Source of Truth is key for any automation effort, but why? What does it represent? Is it just one system? How do we keep it up to date and how in sync with the live network should it be? How do you build it, and how do you maintain it?
Everyone delivering IT service is on a journey - our businesses are so dependent on us as foundation for their process that availability isn't even about SLAs any more – 100% up time is the expectation. And with the dependencies between elements of IT infrastructure becoming ever more complex, we are constantly looking for ways of managing the complexity. In our recent white paper 'The Road to the Self-Driving Network' we dig into the idea that through automation and orchestration, supported by network assurance, we can reach a goal of a self-healing, autonomous network that configures itself to provide the business with the service it needs, then validates that it is doing as it should.
The foundation to that is Intent-Based Networking, which defines a structure for network operations to work smarter now, but drive towards that automated nirvana. It carves up network operations into 3 areas:

Did you miss the Podcast? We got you covered with the recording that you can listen to below!
Intent is the way we describe the service we want the network to provide - how we translate business requirements to network config and policy
Fulfilment is the way we take that intent and render it into actual network device configuration – whether that is manual, through automation or using full service orchestration
Assurance is the way in which we validate the network is doing what it should. This area covers monitoring and performance measurement but also such things as network modelling, behaviour analysis and configuration compliance.
Tim Shreyack, Tim Fiola and Daren Fulwell are experts in each area to discuss the requirements, approaches, and pitfalls from practical experience in the upcoming Podcast.
Tim Schreyack began his career as a network engineer for a DSL provider and progressed to working on large-scale cloud provider networks. With a background in software development, he became an early adopter of network automation, writing code to facilitate network workflows. As a Senior Solutions Architect at Network to Code, he now guides clients on their journey to functional automation.
Tim Fiola is a Solutions Architect at Network to Code and has a network engineering and Python coding background. One of Tim's goals is to show how network automation can make network engineers a strategic asset by freeing them from high-volume, low-value tasks, allowing them time to do high-value network engineering. Tim has authored two books for Juniper Networks: "This Week - Deploying MPLS" and "Day One - Navigating the Junos XML Hierarchy."
Tim also has an open source project called "pyNTM" which helps network engineers and capacity planners by allowing them to simulate failures, topology changes, and traffic changes on their wide area networks (WANs). In his spare time, Tim spends time with his family, staying fit, and maybe or maybe not wasting time by playing Halo for hours on end.
Daren Fulwell is a Cisco Champion, Member of the CCIE advisory council, CCIE, CCDE and IP Fabric’s Network Automation Evangelist among many other things. Daren has spent the best part of 25 years working in our industry and has seen many changes over that time, but his true passion is in Network Automation. Daren is a leading light in the community, being a regular guest on podcasts and giving his view in interviews and blog pieces on the role of automation and its future uses, as well producing vast amounts of content with #init6, and many other outlets.
Daren has held roles with global giants in telecoms, banking and transportation but took a leap into the vendor world to join IP Fabric last year.
Dave Donohue is BlueCat’s first-ever Cloud Architect, helping to educate and guide customers along their cloud journey. Prior to that, he was a Solution Architect for BlueCat, working with customers to help them understand BlueCat’s offerings and engineer solutions. With over two decades of experience in many different IT fields of practice, he started his career in the operations world as tech support. He then moved on to become a network architect, working at Google, Sykes, and ExtraHop Networks, before landing at BlueCat.
