• Toil automation
• Construct feedback loops to decide what to build next
• Agree to consequences of not meeting the error budget
• 1.2 Manage service life cycle:
• Manage a service (e.g., introduce a new service, deploy it, maintain and retire it)
• Balance change, velocity, and reliability of the service:
• Define SLOs and understand SLAs

Building and implementing CI/CD pipelines for a service

• Deployment to hybrid and multi-cloud environments with Anthos, Spinnaker, Kubernetes
• CI/CD pipeline triggers with Cloud Source Repositories, Cloud Build GitHub App, Cloud Pub/Sub
• Deployment strategies with Cloud Build, Spinnaker
• Artifact repositories with Container Registry
• Design CI/CD pipelines:
• Testing a new version with Spinnaker
• Immutable artifacts with Container Registry
• Artifact versioning strategy with Cloud Build, Container Registry
• Configure deployment processes (e.g., approval flows)

Implementing service monitoring strategies

• Implementing a project-level / org-level export
• Collecting logs from Compute Engine, GKE with Stackdriver Logging, Fluentd
• Set ACL to restrict access to audit logs with IAM, Stackdriver Logging
• Sending application logs directly to Stackdriver API with Stackdriver Logging
• Viewing logs in the GCP Console
• Implementing logs-based metrics
• Set ACL to restrict export configuration with IAM, Stackdriver Logging
• Using basic vs. advanced logging filters
• Manage application logs:
• Collecting GKE/Kubernetes metrics
• Sending logs to an external logging platform
• Set ACL to allow metric writing for custom metrics with IAM, Stackdriver Monitoring
• Understanding the logging exclusion vs. logging export
• Collecting third-party and structured logs with Stackdriver Logging, Fluentd
• Enabling VPC flow logs
• Use metric explorer for ad hoc metric analysis
• Enabling data access logs (e.g., Cloud Audit Logs)
• Viewing export logs in Cloud Storage and BigQuery
• Collecting metrics from Compute Engine
• Selecting the options for logging export

Optimizing service performance

• Utilize Stackdriver to identify cloud resource utilization
• Troubleshoot issues with the image/OS
• Utilize Stackdriver Trace/Profiler to profile performance characteristics
• Consider network pricing
• Manage preemptible VMs
• TCO considerations
• Identify service performance issues:
• Interpret service mesh telemetry
• Evaluate and understand user impact (Stackdriver Service Monitoring for App Engine, Istio)
• Develop a plan to optimize areas of greatest cost or lowest utilization
• identify resource costs
• Troubleshoot network issues (e.g., VPC flow logs, firewall logs, latency, view network details)
• Work with committed-use discounts
• Identify resource utilization levels

Managing service incidents

• Perform an investigation to isolate the most likely actual cause
• Rotate/hand over roles
• Provide regular status updates, internal and external
• Identify alternatives to mitigate the issue
• Scaling response team and delegation
• Define roles (incident commander, communication lead, operations lead)
• Avoid exhaustion/burnout
• Record major changes in incident state (When mitigated? When all clear? etc.)
• Evaluate symptoms against probable causes; the rank probability of cause based on observed behavior
• Identify probable causes of service failure
• Coordinate roles and implement communication channels during a service incident:
• Establish communications channels (email, IRC, Hangouts, Slack, phone, etc.)
• Manage stakeholder relationships
• Handle requests for impact assessment
