A Holistic Approach to Network Observability: Beyond the “Five Steps”

In a recent article on BetaNews, Song Pang outlines five steps to achieve network observability: Network Discovery and Data Accuracy, Network Visualizations, Network Design and Assurance, Automation, and Observability. While these steps provide a solid foundation, we believe there are alternative approaches that can be more effective, especially in today’s rapidly evolving network environments. Here, we propose a different set of steps and actions to achieve network observability, explaining why this approach might be superior with clear examples and historical facts.

BetaNews approach focuses on accurate data from logs, traces, traffic paths, and SNMP. We suggest getting a wider system’ view: instead of just focusing on traditional data sources, integrate data from a wider array of sources including cloud services, IoT devices, and user behavior analytics. This holistic view ensures that no part of the network is overlooked.

For example, back in 2016, a major retail company faced a significant data breach because their network monitoring only covered traditional data sources. By integrating data from IoT devices and user behavior analytics, they could have detected the anomaly earlier.

Real-Time Anomaly Detection with AI

BetaNews approach emphasizes network visualizations and manual baselines. This is great as a start, but you should consider implementing an AI-driven real-time anomaly detection. AI can learn normal network behavior and detect deviations instantly, reducing the time to identify and resolve issues.
In 2020, a financial institution implemented AI-driven anomaly detection, which reduced their mean time to resolution (MTTR) by 40% compared to their previous manual baseline approach.

Proactive Incident Response

BetaNews did not suggest that, but you should be ahead of any network issue. Develop a proactive incident response strategy that includes automated responses to common issues. This reduces downtime and ensures quicker recovery from incidents. A tech company in 2018 implemented automated incident response for their network. This proactive approach reduced their downtime by 30% during network outages.

Continuous Improvement and Feedback Loops

Establish continuous improvement and feedback loops. Regularly review and update network policies and configurations based on the latest data and trends.
In 2019, a healthcare provider adopted continuous improvement practices for their network observability. This led to a 25% improvement in network performance over a year.

User-Centric Observability

While BetaNews approach ends with achieving observability, you can focus on user-centric observability. Ensure that the network observability strategy aligns with user experience and business goals. This ensures that the network not only functions well but also supports the overall objectives of the organization.
A global e-commerce company in 2021 shifted their focus to user-centric observability. This alignment with business goals led to a 20% increase in customer satisfaction and a 15% boost in sales.

Common Mistakes in Network Monitoring

While striving for network observability, it’s crucial to be aware of common mistakes that can undermine your efforts:
Many teams adopt a reactive stance, addressing threats only after they occur. This can leave networks vulnerable to evolving threats. A proactive approach, constantly updating antivirus and cybersecurity practices, is essential.

  • Focusing solely on devices and neglecting applications can lead to incomplete visibility.
  • Monitoring both devices and applications ensures a comprehensive view of network performance and potential vulnerabilities.
  • Failing to monitor network logs can result in missed signs of breaches or performance issues. Regular log analysis is crucial for early detection of anomalies.
  • Not anticipating network expansion can lead to scalability issues. Planning for growth ensures that the network can handle increased traffic and new devices.
  • Using outdated tools can leave networks exposed to new types of threats. Regularly updating and upgrading monitoring tools is vital to maintain robust security.

Conclusion

While the five steps outlined by BetaNews provide a structured approach to network observability, the alternative steps proposed here offer a more comprehensive, proactive, and user-centric strategy. By integrating diverse data sources, leveraging AI, implementing proactive incident response, establishing continuous improvement practices, and focusing on user experience, organizations can achieve a higher level of network observability that not only ensures network performance but also supports business objectives.
