No one wants to get an alert in the middle of the night. No one wants their Slack flooded to the point of opting out from channels.

Getting the right alert to the right person through the right channel — with the goal of initiating immediate action — is the last mile of observability.

Imagine a symphony where every musician plays their part flawlessly, but without a conductor to guide the orchestra, the result is just a discordant mess. Now apply that image to the modern IT landscape, where development and operations teams work with remarkable autonomy, each expertly playing their part. Agile methodologies and DevOps practices have empowered teams to build and manage their services independently, resulting in an environment that accelerates innovation and development.
