The traditional Network Operations Center was designed for a simpler era — fixed topologies, predictable traffic and a team of engineers who could hold the entire environment in their heads. That era is over. And yet, most organizations are still running the same NOC playbook from fifteen years ago.
The result? Alert fatigue. Slower diagnosis. Higher MTTR. Good engineers leaving because they spend their days babysitting dashboards instead of solving real problems.
What has actually changed in network operations
Three things have fundamentally shifted in the last five years:
Network complexity has outpaced team capacity
SD-WAN overlays, campus fabrics, cloud interconnects, data center automation — each domain runs its own controller, its own telemetry, its own alerting. Cross-domain correlation still lives inside engineers' heads, not in the tooling.
Talent scarcity is structural, not cyclical
The engineers who understand APIs, Terraform, cloud networking and routing protocols are expensive and rare. When they leave — and they do — their institutional knowledge goes with them. Junior staff inherit undocumented environments and start from scratch.
Reactive operations cannot scale
Most Network are built to react to Incident only lens, while most offered Network Operations do not measure and improve efficiency of Change, Problem, Service Catalogue due to the following reasons:
- Incident Management - Slow recovery to reactive ops, missing knowledge and runbooks and fragmented visibility.
- Change Management- manual and slow approval, poor governance, incomplete audit trails and siloed execution.
- Problem Management – Reactive problem management, issue found during post-mortems, incomplete audit trails or configurations issues, work around and un-document fixes.
- Service Catalogue – stale catalogue, manual fulfilment – delays untracked – handoffs.
The case for autonomous network operations
The question organizations are now asking — across forums, analyst briefings and RFPs — is how to operate larger networks with the same or smaller teams. Automation alone doesn't answer it. Runbooks and Ansible playbooks help, but they're brittle and don't adapt.
The architecture that changes the equation has three components:
Continuous, normalized telemetry
Trap, syslog, flow and streaming telemetry from every domain — normalized into a single event pipeline. Behavioral baselining per device, not just global thresholds.
AI-assisted triage with a human gate
When incident fires, the system correlates topology, config state and historical incident context. It performs a root cause, a confidence score of the resolution suggested and this is updated in the respective ITSM Incident ticket. An engineer reviews the suggested remediation and can update the suggested remediation or approve the recommended fix for the platform to executes autonomously. Tickets with high confidence score can be pre-approved and low priority can be executed automatically and the Tickets is updated with the logs of the changes done.
A governed change pipeline
Every change which is executed by the platform, does not matter whether it is human-initiated or AI-recommended — it goes through these steps of config validation, blast radius calculation, digital twin simulation, policy checks, staged rollout and automated verification. The audit trail is automatically stored in in the ITSM to keep a track of what configuration of the devices has change so in case of a problem the configuration can be rolled back.
The shift: From NOC technician to network reliability engineer
The semi-autonomous operations that we are trying to achieve the requirement is people, process, tools, automation and DevOps principles come together to bring reach this maturity.
It is a journey on which the Customer and/or their Managed Service Providers must work towards and depending on the size of the Network will take from 12-16 months. A typical way is that Autonomous operations don’t eliminate engineers — it changes what they do. The journey starts with standardizing the architecture as per SLA, sanitizing the Observability layer parameter, thresholds values, implement a single source of truth for the network which has a true picture of the network at any point of time, integrate with automation and DevOps ways of working, keep iterating on runbooks for Incident, Change and Service Catalogue implementation. Customers should start with the tickets which are in highest count in the environment.
Organizations/Managed Services that intend to do modernize their operations have to upskill their resources from L1, L2 and L3 to resources with Network skill set and additionally Python, AIOps, DevOps, Ansible, CI/CD, SRE Concepts like toil, error budget.
There are significant benefits if Customer/MSP move on this path and they are going to definitely work achieve measurable outcomes: auto-resolution rates above 70%, Mean-time-to detect and mean-time-to-resolve to under 15 minutes for different ticket categories and a significant reduction in after-hours escalations. The knowledge base compounds over time — every resolved incident becomes training data for the next.
What good looks like in a managed services context
For enterprises that don't want to build and operate this stack internally, the managed services model is maturing fast. The better providers now offer a platform-based shared NOC — multi-tenant, AI-assisted, with per-customer isolation.
HCLTech's Managed Network Services practice has built this out as a production capability — a multi-Tenant platform-based shared NOC that covers WAN/SD-WAN, Campus/wireless LAN and data center environments under a single operational model.
HCLTech platform-based services improves user experience and reliability offering better economics while delivering closed-loop detection, remediation and optimization meaningfully different from traditional dedicated NOC engagements.
The bottom line
The traditional NOC isn't going to transform itself. The teams running it are doing their best with strong tooling (AIOps included), processes, people with operations that haven't kept pace with what networks have become.
Network Automations takes the deterministic calls, while un-resolved complex tickets are fed to AI to enrich and update the relevant information and suggest probable resolution for humans take decisions. Every incident or intent-based change feeds back into the system — that's when network operations start becoming a competitive one. Autonomous network operations are where the industry is heading to deliver reliable networks at lower cost.
