Before we dive in, let's first take a quick look Kubernetes architecture and logging.

Elasticsearch vs MongoDB - Battle of Search and Store

Elasticsearch is primarily a search engine optimized for fast, complex search queries, especially text searches, and is often used for log and event data analysis. MongoDB, on the other hand, is a general-purpose, document-oriented database that excels in storing and retrieving structured and semi-structured data. It is commonly used for mobile, social, and IoT applications. While Elasticsearch provides superior search capabilities, MongoDB offers more robust data processing and storage features.

Getting Started with OpenTelemetry Visualization

OpenTelemetry is a Cloud Native Computing Foundation(CNCF) project aimed at standardizing the way we instrument applications for generating telemetry data(logs, metrics, and traces). However, OpenTelemetry does not provide storage and visualization for the collected telemetry data. For OpenTelemetry visualization, you need to use a backend that can ingest the collected data and provide a web UI to visualize it.

OpenTelemetry vs Prometheus Detailed Comparison

Both OpenTelemetry and Prometheus are open-source projects under the Cloud Native Computing Foundation.
