Capítulo 15. Observabilidad con Hubble

Hubble se basa en Cilium y eBPF, y proporciona una visibilidad profunda de cómo se comunican y se comportan las aplicaciones. Se centra principalmente en la observabilidad de las redes, ayudando a los operadores a comprender las dependencias entre los servicios e identificar problemas de rendimiento o seguridad.
Lo que hace que Hubble sea especialmente valioso es que proporciona visibilidad no solo en las capas 3 y 4, donde operan la mayoría de las herramientas de flujo, sino también en la capa 7. Esto significa que puede revelar información a nivel de aplicación, como métodos HTTP o consultas DNS, lo que te ofrece una visión más completa del comportamiento del tráfico. Hubble también muestra el contexto relacionado con la seguridad, como las conexiones bloqueadas y las políticas que las causaron, lo que te permite refinar las políticas de red basándote en los flujos observados.
Todo esto ocurre de forma transparente, sin necesidad de modificar las propias aplicaciones. Además de la visibilidad del flujo en tiempo real, Hubble expone las métricas de Prometheus, lo que permite la integración con herramientas de observabilidad comunes, como Prometheus y Grafana, para el monitoreo y las alertas.
