Why care about tagging

In Organizations without a clear tag policy, naming is left to everyone's goodwill, and inconsistencies quickly result. Your cloud infrastructure will be a mess, preventing you to operate it efficiently, when it comes to paying the bill you will be unable to detect abnormalities.

At first the tags will allow you to simply name your resources. This is level 0. Then it will become handy to find your resources, then to classify them. Their interest should grow and go beyond the purely infra part to be more transversal.

  • Automation: In addition to making resources easier for IT to manage, a proper organizational scheme allows you to take advantage of automation as part of resource creation, operational monitoring, and the creation of DevOps processes.

  • Workload optimization: Tagging can help identify patterns and resolve broad issues. Tag can also help identify the assets required to support a single workload. Tagging all assets associated with each workload enables deeper analysis of your mission-critical workloads to make sound architectural decisions.
