Operational Excellence

The Operational Excellence pillar of the GCP Architecture Framework focuses on your ability to run, monitor, and continuously improve your cloud workloads. It covers the processes, culture, and tooling that enable teams to operate services reliably and efficiently. A workload with strong operational excellence is observable, automated, and continuously improving.

Design Principles

Principle	Description
Automate everything	Manual processes are error-prone and do not scale — automate deployments, testing, and remediation
Monitor and observe	You cannot improve what you cannot measure — instrument every layer of your stack
Learn from failure	Use incidents as opportunities to improve systems and processes through blameless post-mortems
Manage change safely	Deploy frequently in small batches with automated rollback capabilities
Codify operations	Treat operational runbooks, configurations, and policies as code

Infrastructure as Code (IaC)

All infrastructure on GCP should be defined and managed as code. This ensures consistency, repeatability, and auditability.

Terraform on GCP

# Define a GKE cluster with Terraform
resource "google_container_cluster" "primary" {
  name     = "production-cluster"
  location = "europe-west2"

  remove_default_node_pool = true
  initial_node_count       = 1
