Observability 2.0: Much More Than The Three Pillars

The digital panorama is a dynamic and ever-moving entity. Applications are no longer monolithic giants dwelling on predictable servers. Instead, they are complex webs of microservices, ephemeral serverless capabilities and containerized workloads, all operating across dispersed, multi-cloud environments.

For years, the solution has been 'observability,' often described by its 'three pillars': Metrics, Logs and Traces. These pillars have served us well, offering important information about system health.
