Operational Challenges
Understand the common operational challenges faced in legacy network management, such as lack of a source of truth, complex documentation, scaling difficulties, high error potential, and staffing demands. This lesson helps you recognize why automation is essential to improve efficiency, reduce errors, and manage large-scale networks effectively.
Problems with the legacy approach
Many challenges exist with the legacy approach to managing networks. Whether through CLI device-to-device, or through complicated and- expensive- NMS solutions, network management requires a great deal of CLI work.
The following is a list of key problems inherent to the legacy approach:
No source of truth
- Networks often lack a source of truth, which is an authoritative artifact that can be referenced for what the desired working configuration of a device or set of devices is.
- Networks are often decentralized in project folders, file shares, Visio diagrams, Excel spreadsheets, and local drives.
