Observability means to understand what’s happening across all the components of an application and using it to detect and resolve issues keeping the systems reliable and efficient.
As the application architecture is getting complex day by day, it would be difficult for the SRE/OPS team to have a proper monitoring/ failure detection setup for each and every component that’s where observability beats monitoring.
Modern cloud environments are dynamic and constantly changing in scale and complexity, most problems are neither known nor monitored. Observability addresses this common issue of “unknown unknowns,”.
