Why Chaos Engineering is a Game Changer for Building Better Systems

- Advertisement -

With the speed at which technology is developing, the need for robust and trustworthy software systems has grown significantly. Systems are nonetheless susceptible to failure even with the most advanced technologies. This is the essential manifestation of chaos engineering.

Chaos engineering, a phrase coined by Netflix, is the process of conducting controlled tests to identify flaws in a system. Testing resilience and identifying and resolving failure modes in advance of the system being seriously harmed is a methodical technique. Contrary to what the name may imply, chaos engineering events are carefully planned, and service interruptions are timed to see if systems can withstand disruptions, how the user experience could be harmed, and whether the reaction protocols and warnings are effective.

Chaos engineering has uses for whom?

While eCommerce and IT behemoths were the initial adopters of chaos engineering, it is now essential for organisations of all sizes. Now, chaos engineering has a presence in a variety of industries, including manufacturing, healthcare, finance, and more. Chaos engineering may be used to improve development and testing procedures in any organisation that depends on software to deliver digital convenience.

The advantages of using Chaos Engineering

According to Gremlin’s State of Chaos Engineering 2021 study, businesses who routinely experiment with chaos engineering have uptime rates of above 99.9%. Furthermore, 23% of respondents had an MTTR (mean time to repair) of less an hour and 60% had an MTTR of under 12 hours. These figures show the practical advantages of applying chaotic engineering techniques to an organization’s infrastructure, offering guidance on how to enhance system resilience and lessen the effects of possible breakdowns.

Chaos engineering enables organisations to address important problems, such as how their services react when faced with accessibility challenges or how their applications manage unexpected surges in traffic, by imitating real-world occurrences. Furthermore, it can reveal potential cascading failures that might happen if a single service fails as well as how the system handles network problems.

Testing for system resilience: the best strategy

It is essential to verify a system’s resilience to make sure it can swiftly recover from any problems while maintaining a respectable level of service. Having a solid grasp of the system’s foundation, applications, and dependent components is the first step in successfully applying a chaotic engineering strategy.

Developing Service Level Indicators (SLIs) that specify the crucial performance parameters that must be observed during the chaotic experiment is also crucial. Teams here should ideally do fault injection tests, failure mode analysis, assess data resilience, configure and test health probes, and validate network availability. The chaotic experiment must then be tested in a staging environment. This is necessary to reduce the possibility of the production environment being disrupted and to make sure that the experiment can be carried out safely.

In order to reduce the effect of potential dangers, it is crucial to make the explosion radius as small as possible during the initial trial. Organisations may use GameDays to regularly stress test their systems because chaotic engineering is a continuous endeavour. GameDay is a collaborative, interactive learning activity that lets participants test their knowledge in a safe, risk-free setting. Teams can conduct chaotic engineering experiments on the systems for a designated day to replicate actual turbulence and test how they, their team, and their supporting systems would react.

Incorporating visibility and observability

Chaos experiments are a good approach to quickly find problems without spending too much effort on fundamental causes. Teams require a strong visualisation technique in order to assess a system’s performance during these tests. To aid with this endeavour, several monitoring and warning systems are available. Prometheus is a well-known time-series database that gathers data from many sources and offers real-time insights. Multiple data sources are supported by tools like Grafana, which may also assist teams in creating unique dashboards.

The way we develop robust systems through the intuitive process of chaos engineering has the potential to completely alter how we create, test, and deploy software. Chaos engineering is becoming into a crucial technique for assuring the dependability and stability of systems in the face of unforeseen occurrences as technology develops and systems get more sophisticated.
