Prometheus Our Service Leads use Prometheus as a powerful monitoring and alerting system for Kubernetes. It collects real-time metrics, stores them in a time-series database, and enables querying with PromQL. With built-in alerting and visualisation support, Prometheus helps monitor application performance, detect anomalies, and ensure system reliability and scalability.

Helm Our Service Leads use Helm, which is a package manager for Kubernetes. It uses 'charts' as its package format, which is based on YAML.

Configmap Our Service Leads use Configmap, which is an API object that is mainly used to store non-confidential data. The data that is stored in ConfigMap is stored as key-value pairs. ConfigMaps are configuration files that may be used by pods as command-line arguments, environment variables, or even as configuration files on a disc.
