Starter Guide | Build a Heat Map Tile App with Alibaba Cloud ECS and PostgreSQL in One Click

This tutorial describes how to build interactive heat map to realize geo visualization and real-time analytics by Ganos on ApsaraDB RDS for PostgreSQL.

This article focuses on one-click deployment through the Alibaba Cloud console. If you need to use scripting for automated deployment, you can refer to this article that uses Terraform.

Overview

A Heat Map Tile is a data visualization tool that represents the spatial distribution of data by overlaying colored tiles on a map. Each tile's color intensity reflects the magnitude or concentration of a particular metric within that area. Heat Map Tiles are often used to visualize geographic data, making it easier to identify patterns, trends, and outliers at a glance.

Billing Instructions

The expenses on Hmt mainly involve:

  1. Selected vCPU and memory specifications
  2. System disk type and capacity
  3. Public network bandwidth
  4. ApsaraDB RDS for PostgreSQL specifications and storage space
