Microservices and distributed architectures became the norm for building modern-day applications. While the cloud has made it easier to deploy and scale microservices, it's opened a posh set of problems for DevOps by virtue of the sheer volume of interactions between those services.
Tracing a blunder across a microservice architecture could be a huge challenge, and without proper insight, longer are required to resolve issues, resulting in an increased unit of time To Resolve (MTTR) in all about business related critical situations for along DevOps and site reliability engineers (SREs).
This is where observability plays a vital role. As applications become more complex, it's essential to form them observable, because you'll be able to only analyze, monitor, and optimize your system after you know the way it behaves.
This blog discusses observability, the common myths, and also the facts that disprove them.
3 pillars of observability
How does one define observability? If at any given time, you'll be able to assess your system's state, health, and behavior, then your system is observable. you ought to even be able to trace the foundation reason behind a controversy or unearth problems that otherwise go unnoticed.
Correlating data using metrics, logs, and traces shows a holistic picture by your environment. This is kind of often why those metrics, logs, and traces are considered the three pillars of observability.
Myths and facts about observability
As the term "observability" gains traction, there are some misconceptions surrounding it. Below, we'll discuss a number of the common myths together with the particular facts proving them wrong.
Myth: Monitoring and observability are two independent subjects.
Fact: Monitoring and observability go hand in hand. In fact, observability may be a superset of testing and monitoring. A system becoming the observable by gaining visibility via data/metrics from monitoring tools. and also the more observable your system is, the more granular and efficient your monitoring are.
Myth: Observability is barely for tech giants.
Fact: regardless of the scale and scale of your organization, if your application performance affects your business bottom line, then you would like to take a position in making your systems observable. While the concept of observability was initiated by tech giants, it's become a subject of interest among businesses of all sizes thanks to the rise within the adoption of cloud technologies and therefore the complexities related to it. you do not must be an outsized enterprise to implement observability in your systems. whether or not your application is easy, it's imperative to confirm your systems are observable.
Myth: Observability is that the final piece of the puzzle to solving all of your performance problems.
Fact: No, it's not. In fact, making your systems observable is just the place to begin. It doesn't suggest that after you've got achieved observability, the remainder will be sure of itself. By making your systems more observable, you open the window to spot the nitty-gritty details of your application behavior that otherwise go unnoticed. The system also enables you to implement shift-left principles in your DevOps cycle.
Achieving observability
Assess the requirements and requirements of your system before you invest. Define the key performance indicators of your application performance, and start your observability journey from there. Tweak to your defined key performance indicators (KPIs) according to you scale.
Define benchmarks for your KPIs, and establish remedial actions to require place once they are breached.
To Identify, capture, and consolidate the all logs from various services which are affect your key performance indicators. Define the rules for filtering using these logs, and detect anomalous patterns.
