The article compares reactive, proactive, and predictive network management models for complex enterprise infrastructure where increasing device connectivity raises human error and outage risk, causing business interruption and high costs. It explains that reactive SNMP-based approaches generate false positives and firefighting, while proactive methods improve prevention but are limited by heterogeneous tooling and scalability. The predictive model, driven by machine learning and offered by indeni, promises automated predictive analytics, deeper visibility across technologies (including F5, Blue Coat proxies, Cisco, PAN, and Check Point firewalls), and reduced downtime and operational costs.
What are the main drawbacks of continuing to use a reactive network management model?
The article states that reactive models, typically SNMP-based, lead to hundreds of false positives, endless on-call hours, and constant firefighting. As infrastructure complexity grows, these systems produce more alerts and increase the likelihood of outages, which in turn cause business interruptions, reduced user productivity, and damage to brand reputation. Additionally, reactive operations consume time that could be used for strategic work, forcing IT teams to write manual scripts and consult runbooks rather than expanding capabilities, with potential costs reported up to $46 million per year (source: Evolven).
Why is the proactive model considered insufficient for large, heterogeneous environments?
According to the article, proactive methods are better than reactive ones but are difficult to implement manually and depend heavily on disparate tools that specialize in different capabilities (for example, historical bandwidth monitors versus real-time tools). Organizations often hack multiple tools together and create manual checklists for backups or restarts, but this approach suffers from limited scalability and reduced transparency in crowded IT environments. Therefore, proactive techniques can work short-term but are constrained by the monitoring tools’ capabilities and operational overhead.
How does the predictive model improve network management, and what technologies does it support?
The article describes the predictive model as leveraging machine learning to implement predictive analytics and automation that anticipate issues before they escalate into downtime, reducing the need for many separate tools and manual checklists. Benefits include collective network knowledge gathered by machine learning (including remediation steps and links to product information), continuous predictive modeling aimed at high availability (the article cites 99.9999% as an example target), and the ability to reduce service interruptions and operating costs. The article also notes that indeni’s predictive approach supports multiple technologies such as F5, Blue Coat proxies, Cisco, Palo Alto Networks (PAN), and Check Point firewalls.
Proactive, Reactive or Predictive Network Management
Enterprise infrastructure today is complex, where more and more devices are coming online and being connected to more and more networks. As a result of this complexity the potential of human errors will be on the rise. Network outages are becoming more common, since IT teams are being asked to do more with less. As a result, the process of picking a network management software has never been more essential. Enterprises that choose to be reactive will suffer outages that will cause business interruptions, slowdown in user productivity and damage brand prestige. Companies that choose inaccurately can have costs as high as $46MM per year. (Source: Evolven)
Today’s Status Quo and the Risk Involved by Not Opting for Change
As an IT pro, you know the reactive model well. You’re using it now. You learned it from others. Passed down through generations of IT operational teams. With the same old solution (ie: Network Management solutions that are SNMP based), come the same issues: hundreds of false positives, endless hours of being on call, constant firefighting, etc. As the enterprise infrastructure gets more complex, the possibility of outages and failures increases based on the law of probability. If you continue with the status quo reactive model, the likelihood of receiving a service call from an angry user or a system generated alert corresponding to an app failure is almost inevitable. The biggest drawback to IT Ops teams will be time. Time that could have been spent on expanding capabilities will now be reduced to writing scripts manually or searching through runbooks for solutions to prevent the next failure.
The Proactive Model
Being in an IT Ops team, we all know that this model is best for network management, but it is difficult to achieve manually. Some IT pros set priority to sectors of their infrastructure they see as “most vulnerable” and develop their own tool set to implement proactive techniques to manage their network. The problem arises since many of the tools used to have different capabilities. For example a monitor for bandwidth maybe great at handling historical data, while others do better with real time. Many companies do their best with the systems they have by hacking a variety of tools together to create a manageable infrastructure. They often create checklist that will sequence device backups or process that need to be restarted manually. Often this method works, but not for long, since IT pros work in crowded environments where transparency may not always be the norm. The proactive method of network management by itself, is flawed since it’s scalability is limited to the capabilities of the tools used for monitoring failures and outages.
The Predictive Model
With the rise of machine learning algorithms comes a new age in network management: The Predictive Age. Used primarily, by early adopters in IT ops teams, this model implements predictive analytics and automation methods to anticipate issues before they become downtime often without the need of multiple tools and checklists. Imagine being in an IT teams using the predictive method of network management that:
Benefit from the wiki effect of network knowledge gathered by machine learning, often with remediation steps and links to product information about the issue. Enhanced capabilities of 24/7/365 predictive modeling for 99.9999% often elusive with ancient monitoring tools. Furthermore, the predictive model supports multiple technologies from F5, Blue Coat Proxys, Cisco, PAN and Check Point firewalls.
If you’re an IT Pro today, the possibilities of using machine learning to leverage your workload, have deep visibility and reduce service interruption while cutting support and operating costs is here. All with one tool: indeni was created to make the life of IT pros easier, by using a predictive model of network management to ease the burden of complex networks.
With Indeni, you are just steps away from predicting your network outage before the alarms go off or your customers take to Twitter to rant about the lack of performance in your brand.
