Key Concepts of NetOps

Automation

It refers to the process of using tools to perform repetitive manual tasks automatically. NetOps teams can save time and reduce human errors by automating tasks.

Orchestration

Orchestration involves coordinating and managing multiple automated tasks to achieve a specific goal or outcome.

Example: Suppose a company wants to deploy a microservices-based web application that consists of multiple services (each running in its own container). The application requires a frontend service, backend services, a database, and a message broker for communication between services. Orchestration can streamline this complex deployment process.

Monitoring

Network monitoring is the process of observing & collecting data from network infrastructure to gain info on network performance and security. This data is often used to detect and diagnose issues. Monitoring tools can provide real-time data on latency, packet loss, and other performance indicators.

Analytics

It uses data analysis and machine learning techniques to analyze network behavior. Based on the data, NetOps teams can identify patterns and mitigate potential risks.

Telemetry and Streaming

Telemetry is the process of transmitting real-time data from network devices to analytical systems. Streaming telemetry provides continuous data for NetOps teams to monitor & respond quickly to changes.

Software-Defined Networking (SDN)

SDN is a network architecture that separates the network control plane from the data plane. It allows network administrators to manage network services through the abstraction of lower-level functionality.

And here is a detailed post on how SDN works and the types of it. Feel free to visit this post.

NetOps Tools and Technologies

There are a variety of tools associated with NetOps.

#1. Configuration Management Tools

Configuration management is an important aspect of NetOps that allows network administrators to automate the deployment & maintenance of network devices efficiently.

Three popular tools in this domain are:

Ansible

Ansible is an open-source automation platform that simplifies configuration management, application deployment, and task automation. It uses declarative language to define the desired state of the network.

Puppet

Puppet is another widely-used configuration management tool that automates the provisioning and management of network devices. It provides a centralized dashboard to monitor configurations.

Chef

Chef generally focuses on automating the entire infrastructure, including network devices, servers, and applications. It uses a code-driven approach which makes it easy to manage complex network configurations.

#2. Network Monitoring and Performance Tools

Real-time network monitoring is a core element of NetOps as it is used to identify & address issues promptly.

Nagios

Nagios is an open-source monitoring system that provides advanced monitoring and alerting for network devices and applications. It has a user-friendly interface and can be extended with various plugins to suit specific monitoring needs.
