In this lesson, we explore AWS Resource Explorer—a powerful tool designed to simplify the discovery and management of your AWS resources. With Resource Explorer, you can efficiently locate resources across regions, ensuring optimal resource management and cost attribution while reducing compliance risks.
By centralizing resource management, Resource Explorer helps in generating insightful reports and streamlines audits, saving valuable time.

​
Overview of AWS Resource Explorer

Before the introduction of Resource Explorer, managing numerous AWS resources spread over various regions was both inefficient and error-prone. Without a centralized system, cost allocation to specific projects or departments was cumbersome, and inconsistencies in tagging and configurations raised compliance risks. Resource Explorer addresses these challenges by enabling users to locate resources using tags, keywords, and other metadata.
The image is a diagram of an AWS Resource Explorer showing different regions (us-east-1, ap-south-1, eu-west-2) with various service icons. It illustrates how resources can be identified by names, tags, and IDs.
Setting up Resource Explorer is straightforward, requiring just a few minutes to enable and configure.

​
User Roles in Resource Explorer

There are two primary types of users for Resource Explorer:
  1. Resource Explorer Administrator
    The administrator is an IAM principal assigned the permissions necessary to manage Resource Explorer settings. Key responsibilities include:
    • Enabling Resource Explorer in AWS regions.
    • Updating index types.
    • Creating views.
    • Granting search permissions.
  2. Resource Explorer User
    These users have permissions to perform searches for resources. They can utilize the AWS Management Console, SDKs, or CLI to locate and manage resources effectively.
The image shows two icons representing an "Administrator" and a "User" with corresponding symbols, a gear and a magnifying glass, respectively. The background colors are blue for the administrator and orange for the user.

Understanding Indexes in Resource Explorer

In Resource Explorer, an “index” is the collection of information about AWS resources within a specific region. There are two types of indexes:
  • Local Index: Exists within a single AWS region.
  • Aggregator Index: Compiles local indexes from all regions where Resource Explorer is enabled.
Consider a scenario where an administrator has enabled Resource Explorer in three AWS regions and selects the AP South Mumbai region as the aggregator index:
The image is a diagram of AWS Resource Explorer, showing different regions (us-east-1, ap-south-1, eu-west-2) with icons representing local and aggregator indexes.
Each region with a local index automatically replicates its data to the designated aggregator index (in this example, AP South Mumbai). For instance, both US East 1 and EU West 2 replicate their local indexes to AP South 1. As a result, users query the aggregator index in AP South 1 to access consolidated information from all enabled regions.
The image is a diagram titled "Resource Explorer – View and Filter," showing interconnected regions (ap-south-1, us-east-1, eu-west-2) with document icons, illustrating a filtering process.

Benefits of AWS Resource Explorer

AWS Resource Explorer offers several key advantages:
BenefitDescription
Unified Resource SearchEasily locate resources across all regions with one centralized search tool.
No Additional ChargesResource Explorer is free to use, eliminating extra costs.
Time EfficiencyQuickly identify and manage resources from a single, centralized location.
Eliminates Custom SolutionsNo need to develop and maintain a custom search infrastructure.
Enhanced Console ExperienceThe unified search function in the AWS Management Console simplifies administration.
The image lists five features: "Search and Discover Resources," "Free to Use," "Saves Time," "Custom Search Infrastructure Not Required," and "Unified Search," each with corresponding icons.
AWS Resource Explorer is a robust solution for efficient resource management. Its centralized approach not only simplifies operations but also ensures that administrators can monitor and manage assets across multiple regions with ease.
