Implement CI/CD pipelines

• CI with Cloud Build

• CD with Cloud Build

• Open source tooling (e.g. Jenkins, Spinnaker, Git Lab, Concourse)

• Auditing and tracing of deployments (e.g., CSR, Cloud Build, Cloud Audit Logs)

Manage configuration and secrets

• Secure storage methods

• Secret rotation and configuration changes

Manage infrastructure as code

• Terraform / Cloud Deployment Manager

• Infrastructure code versioning

• Make infrastructure changes safer

• Immutable architecture

Deploy CI/CD tooling

• Centralized tools vs. multiple tools (single vs multi-tenant)

• Security of CI/CD tooling

Manage different development environments (e.g., staging, production, etc.):

• Decide on the number of environments and their purpose

• Create environments dynamically per feature branch with GKE, Cloud Deployment Manager

• Local development environments with Docker, Cloud Code, Scaffold

Secure the deployment pipeline:

• Vulnerability analysis with Container Registry

• Binary Authorization

• IAM policies per environment

Manage application logs

• Collecting logs from Compute Engine, GKE with Stackdriver Logging, Fluentd

• Collecting third-party and structured logs with Stackdriver Logging, Fluentd

• Sending application logs directly to Stackdriver API with Stackdriver Logging

Manage application metrics with Stackdriver Monitoring

• Collecting metrics from Compute Engine

• Collecting GKE/Kubernetes metrics

• Use metric explorer for ad hoc metric analysis

Manage Stackdriver Monitoring platform

• Creating a monitoring dashboard

• Filtering and sharing dashboards

• Configure third-party alerting in Stackdriver Monitoring (i.e., Pager Duty, Slack, etc.)

• Define alerting policies based on SLIs with Stackdriver Monitoring

• Automate alerting policy definition with Cloud DM or Terraform

• Implementing SLO monitoring and alerting with Stackdriver Monitoring

• Understand Stackdriver Monitoring integrations (e.g., Grafana, BigQuery)

• Using SIEM tools to analyze audit/flow logs (e.g., Splunk, Data dog)

• Design Stackdriver Workspace strategy

Manage Stack Driver Logging platform

• Enabling data access logs (e.g., Cloud Audit Logs)

• Enabling VPC flow logs

• Viewing logs in the GCP Console

• Using basic vs. advanced logging filters

• Implementing logs-based metrics

• Understanding the logging exclusion vs. logging export

• Selecting the options for logging export

• Implementing a project-level / org-level export

• Viewing export logs in Cloud Storage and BigQuery

• Sending logs to an external logging platform

Implement logging and monitoring access controls:

• Set ACL to restrict access to audit logs with IAM, Stack driver Logging

• Set ACL to restrict export configuration with IAM, Stack driver Logging

• Set ACL to allow metric writing for custom metrics with IAM, Stack driver Monitoring

Identify service performance issues

• Evaluate and understand user impact (Stackdriver Service Monitoring for App Engine, Istio)

• Utilize Stackdriver to identify cloud resource utilization

• Utilize Stackdriver Trace/Profiler to profile performance characteristics

• Interpret service mesh telemetry

• Troubleshoot issues with the image/OS

• Troubleshoot network issues (e.g., VPC flow logs, firewall logs, latency, view network details)

Debug application code:

• Application instrumentation

• Stackdriver Debugger

• Stackdriver Logging

• Stackdriver Trace

• Debugging distributed applications

• App Engine local development server

• Stackdriver Error Reporting

• Stackdriver Profiler

Optimize resource utilization:

• Identify resource costs

• Identify resource utilization levels

• Develop plan to optimize areas of greatest cost or lowest utilization

• Manage pre-emptible VMs

• Work with committed-use discounts

• TCO considerations

• Consider network pricing

Coordinate roles and implement communication channels during a service incident:

• Define roles (incident commander, communication lead, operations lead)

• Handle requests for impact assessment

• Provide regular status updates, internal and external

• Record major changes in incident state (When mitigated When all clear etc.)

• Establish communications channels (email, IRC, Hangouts, Slack, phone, etc.)

• Scaling response team and delegation

• Avoid exhaustion / burnout

• Rotate / hand over roles

• Manage stakeholder relationships

Investigate incident symptoms impacting users

• Identify probable causes of service failure

• Evaluate symptoms against probable causes; rank probability of cause based on observed behavior

• Perform investigation to isolate most likely actual cause

• Identify alternatives to mitigate issue

Mitigate incident impact on users:

• Roll back release

• Drain / redirect traffic

• Turn off experiment

• Add capacity

Resolve issues (e.g., Cloud Build, Jenkins):

• Code change / fix bug

• Verify fix

• Declare all-clear

Document issue in a post-mortem:

• Document root causes

• Create and prioritize action items

• Communicate post-mortem to stakeholders
