Observation has been the most acceptable and promising way to evaluate and analyze the performance of any complex system. What makes this technique one best approach is the fact that it does not require any technical expertise and can be performed without any cost. Observability not just identifies the loopholes it also helps the decision makers in  efficient decision making.

Observability is the proactive approach which prepares the system and organization for any after effect or risks. Its application is not just confined to any one field. Instead it has wide horizon of application in health, business, and also in technological world. In digital world, to understand how your complex digital system behaves, you can use observability, which proactively gathers, visualizes, and applies intelligence to all of your metrics, events, logs, and traces.  In short, observability enables the system to evaluate its performance or its internal condition by taking its output in consideration.

This article is about what is observability? and why is this important for the complex systems?. Let’s get started. 

What is Observability?

“Future is not about predicting, rather it is about preparing for better”

That’s what experts believe and so do top tech companies and some leading business tycoons have already started working on. This is what observability offers to the future.

Observability is a technique used in contemporary technological environments to find problems by keeping an eye on both the inputs and outputs of the technology stack. In order to address problems before they have an impact on business KPIs, observability technologies gather and analyze a wide range of data, including application health and performance, business metrics like conversion rates, user experience mapping, and infrastructure and network telemetry. It implies The quicker and more accurately you can trace a performance issue back to its source without further testing or code, the more observable a system is.

Applied observability is the application of AI to observe and analyze collected data. Since it is founded on verified stakeholder actions rather than intentions, applied observability is more about clarity than innovation. Data allows us to observe the actual results even if we don’t know what the decision was or if it was carried out differently than we had intended. We can establish a feedback loop that enables a company to make future decisions more quickly and accurately by integrating the context in which that data was collected and then utilizing AI to analyze and offer recommendations.

Applied Observability


Applied observability is the use of observable data in business functions, applications, infrastructure, and operations teams in a highly orchestrated and integrated manner. It makes it possible to reduce the lag between stakeholder actions and organizational responses, allowing for proactive planning of business decisions. 

Organizations are able to respond in almost real-time thanks to applied observability. Response time promotes client loyalty and satisfaction. Shorter feedback loops between stakeholder actions and organizational responses allow for proactive planning of company decisions based on positive, negative, or ambiguous consumer behaviors (or lacking in information).

Tesla is an example of this technology in the real world. Tesla only provides insurance based on “observable” in-vehicle behavior. Tesla automobiles use sensors to “observe” and evaluate driver behavior, creating a monthly safety score. The average driver could save 20% to 40% on their premium, and the safest drivers could save 40% to 60%, according to estimates.

Components of Applied Observability 

In a basic digital system, applied observability has following components: 

  • Implementation 
  • Multiple Concurrent Data Layers  
  • Democratized Opportunity

Why is Observability Important? 

APM and NPM have been the main tools used by IT teams to monitor and debug applications and the networks they use for the past 20 years or so. While NPM systems give organizations the knowledge to solve network difficulties, APM systems are sufficient for monitoring and debugging classic distributed applications or monolithic applications. However, companies are increasingly moving at such a rapid rate that NPM and APM are unable to keep up.

Scalable, open source, cloud-native applications powered by Kubernetes clusters are replacing traditional systems in the modern day. They are being created and delivered more quickly than ever before by distributed teams. DevOps, continuous delivery, and agile development have sped up the entire software delivery process, but this might make it more challenging to identify problems as they emerge.

Observable data is significant because it is based on verified stakeholder actions rather than intentions, responsibilities, or promises, making it a truly evidence-based source of decision-making. Organizations can exploit their data artefacts for a competitive advantage thanks to applied observability. Applied observability has proven to be a potent method for data-driven decision making when carefully designed and successfully implemented. Without an observability solution, it can be very difficult to locate a broken link when working on these intricate, distributed systems. You require distributed tracing to track requests—and bottlenecks—across all components of a distributed system.

Observability Vs Monitoring 

Monitoring and observability are two distinct but related notions. Traditional monitoring won’t help you succeed in the challenging world of distributed systems and microservices. It is limited to tracking known unknowns. Observability provides teams with the contextual knowledge they need to uncover and address “unknown unknowns,” or problems they are not yet aware of, while monitoring works by gathering and analyzing data known to be connected to application, system, or network performance issues.

Monitoring tools track down lost connections or malfunctioning devices and update the overall network health. To assess how the network is operating and report on any performance concerns found, they often use network operation protocols.

Observability systems, on the other hand, automatically and continuously gather performance data from various distributed IT environments and correlate it in real-time, enabling users to quickly understand what is happening and why without having to predefine the precise data collected or tagging used. Observability solutions offer an exploratory function that goes beyond merely providing improved monitoring. This function provides users with the application and infrastructure context necessary to dynamically query operational data and reveal insightful information.

How is Applied Observability Helpful to DevOps? 

Since the systems are developing so drastically, applied observability gives DevOps teams the latitude they require to test their systems in production, pose queries, and look into problems they couldn’t have foreseen at first.

In addition to this, it renders followings facilitation to the DevOps team:

  • Analyzing infrastructure resources and application requirements, as well as reviewing progress, can help developers consistently enhance the software user experience.
  • To improve DevOps procedures, gather around team dashboards, coordinate reactions, and track the results of each modification.
  • Set up instrumentation, define specific service-level objectives (SLOs), and prepare for and collaborate toward measurable success.

Benefits of Applied Observability 

Improved Processes

With applied observability, it is simpler for engineers to troubleshoot issues in distributed computing settings when they have visibility into the entire history of a request from start to finish. This improves workflows, saves time, and gets rid of the need to contact outside suppliers to find out about server reliability or app performance.

Accelerated Development

Applied observability’s ability to generate quick problem diagnosis and resolution speeds up software development, resulting in cost savings and giving developers more time to concentrate on providing enhanced product features. Developers can better understand system performance and produce better products if given an increased global view of the whole system architecture, including any third-party apps and services.

Increased System Transparency

Developers can pinpoint exactly where issues have occurred or system performance has declined by obtaining detailed data in real time indicating which programmes are at fault when performance issues arise.

Prior Warnings

It is simpler for developers to immediately fix any difficulties since they can learn about problems more quickly and obtain more detailed information about modifications that have been made to a system.
