Datadog has introduced Host Maps, a new feature designed to provide a comprehensive view of all hosts in a user's infrastructure on a single screen, allowing for customizable grouping and filtering with visual metrics. This tool aids in spotting outliers, detecting usage patterns, and optimizing resources across various scales, from small setups to extensive infrastructures with thousands of hosts. Host Maps offer flexibility for users to ask infrastructure-level questions and obtain instant, visual answers, particularly useful for tasks like resource optimization where users can analyze AWS instance types and their utilization. Additionally, Host Maps facilitate understanding availability zone placements and assist in problem investigations by allowing users to group hosts by different dimensions to identify issues quickly. This feature enhances operational efficiency and understanding of infrastructure, making routine operations more intuitive and engaging for teams.
