Automated infrastructure activities
Tags can be used in a wide range of automation activities when managing infrastructure. Use of AWS Systems Manager for example will allow you to manage automations and runbooks on resources specified by the defined key-value pair you create. For managed nodes, you could define a set of tags to track or target nodes by operating system and environment, you could then run an update script for all nodes in a group, or review the status of those nodes. Further to this, Systems Manager Resources themselves can also be tagged to further refine and track your automated activities.
Automating the start and stop lifecycle of environment resources
can provide a significant cost reduction to any organization.
