DevOps and SRE teams are under intense pressure to reduce the Mean Time to Recovery (MTTR) in resolving incidents. With the proliferation of cloud services and the increasing complexity of DevOps toolchains, engineers today need to not only learn how to use these services but also troubleshoot them when an incident is raised at 2 AM. Incident response is still manual today – cobbling together runbooks and ad hoc scripts and orchestrating people to respond.
In an ever-changing world, the future of work is changing as well, and it has accelerated some areas of automation that we were already moving toward.

Datadog is an awesome tool for aggregating and visualizing the metrics that matter to you. Recently, Datadog launched a new Incident Management feature, which allows you to coordinate the activities around a problem that affected your service. In this example, I’ll walk through using Relay to roll back a Kubernetes deployment that caused a service impact, and show how the Datadog Incident timeline can keep everyone working on the incident in sync.
When you see a notification on your smartphone, your brain processes the request quickly and determines how to react. It’s an efficient process and your nervous system is built for this use case. By contrast, most Internet-connected systems work in a less event-driven architecture. If there’s a change in one service, you won’t know about it until you check.

If not, then you may want to visit these prerequisites.
