What are the best practices for a NOC?

Best practices for a network operations center – prepare training, rely upon clearly portrayed roles, and set up clear protocols for communication.

Concentrate on training and knowledge improvement:

Your NOC team must have high-level expertise, expressly in monitoring, managing, and resolving issues specific to network performance and your IT infrastructure. Give powerful and persistent training on procedures and protocols for any event, and keep up-to-date on changing tech scenario and changes to your own IT environment. Organizing network performance issues, yet don’t neglect procedures for cooperating with your SOC on security issues. A key procedural issue is an escalation; guarantee your staff knows how and when to make the quick decision to raise a growing issue to a more experienced associate.

Assign clear jobs:

Flatter organizational systems are more popular these days. In the fast-paced, must-act-now world of network monitoring, it looks good to empower every associate instead of firmly requesting position or role-based handoffs. In any case, while technicians need to be outfitted with the data and capacity to act quickly to resolve network failures, you still need escalation levels and shift supervisors to administer the NOC.

NOC technicians are responsible to complete their assigned tasks and share knowledge on the same. And by choice, they need to be micromanaged. You still require a leader who assigns work to techs based on their skills, decide tasks, access reports, make sure to resolve all the reported incidents promptly, and represents the more extended organization of events as required.

Also, every technician should know specifically what projects will be assigned to them, their level, and the line of reporting, should they have to escalate an incident or respond to one.

Enable a solid communication system:

Keeping the lines of communication open within the NOC, SOC, and other external teams can wind up being troublesome. It’s unquestionably something beyond setting up a few occasional meetings. Sometimes, it needs a solid effort to plan staff – in sharing information and thinking of them as responsible contacts for the same. Creating regular opportunities for cooperation and coordination is imperative to a solid NOC.

Build clear principles and protocols:

Keep things running smoothly by making evident policies for the following:

Incident management:

Document steps the technician should follow to manage incidents like – When the technician can make a decision, when to escalate the decision, when to suggest associates, and so on


Outline procedures for managing ordinary issues and give fast strategies for managing emergencies.


Escalation procedures for encountered issues and to whom.


Establish which incidents take the most priority and which level technician should manage the most important ones. Incidents should be allotted relying upon the degree they will impact the business.

Having well-established protocols ensures everyone is on a similar page, gives consistency over the organization, and extends responsibility among NOC staff. Having the right people and processes set up a more reliant foundation.

Hybrid cloud is the foundation for dynamic delivery

A powerful platform, for instance, a hybrid cloud is an engaging operator for the dynamic delivery model. Hybrid cloud is compliance with tools and technologies to streamlines:

  • Virtual collaborations
  • Digital project management
  • Automation
  • Knowledge management processes.

Hybrid cloud can help address security limits too – it allows various applications to run and data to be stored in line with the security, regulatory, and administration conditions. Enterprises can take action on their cloud transition dynamically using Hybrid cloud tools. There are some pre-settings that can accept minimum downtime levels. Tools will help to avoid silos and handle legacy systems.

The Hybrid cloud also allows public and private clouds. And on-premises IT to interoperate continuously using standard technology interfaces. For example – Kubernetes, Linux, and Open Container Initiative.

These technology interfaces help companies to progress with agility and at scale while improving responsiveness and chopping down costs regardless of the growing complexities.

Best Free and Open Source Monitoring Tools for Your Networks:

Picking the right network monitoring solution for your enterprise isn’t easy. IT specialists and bosses need to think about a couple of factors while picking solutions for their business, for instance, security, compatibility, simple-to-use, and (clearly) budget plan.
