This guide provides step-by-step instructions on how to install TimescaleDB, an open-source time-series database built on PostgreSQL, on Amazon Web Services (AWS). The process involves creating an AWS account, launching an EC2 instance with the Ubuntu Server 20.04 LTS image, configuring PostgreSQL, and installing TimescaleDB. Once installed, users can create a hypertable and insert data for querying. This setup enables efficient management of time-series data, events, and analytics while maintaining compatibility with traditional relational databases.
