CI/CD Automation

Service Summary

PES builds automated CI/CD pipelines using GitHub Actions with YAML-based workflow definitions. Our pipelines integrate with AWS CodeDeploy, Azure DevOps, OCI DevOps, and ServiceNow for change management — covering the full deployment lifecycle: Dev → Stage → UAT → Prod, plus Day 2 Operations for ongoing monitoring, patching, and maintenance.

Note: The CI/CD strategies and YAML examples are recommendations based on GitHub Actions and cloud provider best practices. Every pipeline is tailored to your existing toolchain, approval workflows, and compliance requirements.

Components

GitHub — Source control, Actions runners, Environments with protection rules
YAML Workflows — Build, test, security scan, deploy stages
ServiceNow Integration — Automated change request creation and approval gates
Day 2 Operations — Post-deployment monitoring, patching automation, rollback pipelines

AWS — GitHub Actions + CodeDeploy

Pipeline triggers on push to main branch. GitHub Actions runs build and test stages, then deploys to Dev → Stage → UAT → Prod using AWS CodeDeploy with Environment protection rules. ServiceNow change request is created automatically and approval gates block production deployment until approved. Day 2 Operations monitoring via CloudWatch alarms.

Azure — GitHub Actions + Azure DevOps

Pipeline triggers on PR merge. GitHub Actions builds container images published to Azure Container Registry, deploys to Dev via Azure App Service staging slots, then swaps to production after automated smoke tests pass. Azure Key Vault stores secrets. Azure Monitor dashboards track deployment health. Day 2 Operations via Azure Update Manager.

OCI — GitHub Actions + OCI DevOps

Pipeline triggers on tag push. GitHub Actions runs build and security scan, then OCI DevOps handles deployment to OKE (Kubernetes) or OCI Compute. Artifacts stored in OCI Container Registry. ServiceNow integration for change approval. Day 2 Operations via OCI Monitoring and OS Management.

ServiceNow — Change Management Automation

ServiceNow DevOps automates change management within your CI/CD pipeline. When GitHub Actions triggers a deployment, ServiceNow automatically creates a Change Request with CI/CD context — pipeline ID, commit SHA, build artifacts, and test results. Approval gates based on ServiceNow change policies (Standard, Normal, Emergency) block production deployment until authorized. Every pipeline execution is recorded for a complete audit trail.

How the Integration Works

ServiceNow DevOps GitHub Actions — Official ServiceNow/servicenow-devops-change action creates change records from your YAML workflow
REST API — ServiceNow Table API (POST /api/now/table/change_request) for custom integrations
DevOps Data Model — Maps pipeline executions to Change Requests using sn_devops_pipeline_execution table
Authentication — OAuth 2.0 client credentials or Basic Auth stored in GitHub Secrets

Implementation Steps

Install the DevOps plugin in your ServiceNow instance (DevOps Change Velocity)
Create OAuth API endpoint: System OAuth → Application Registry
Store credentials in GitHub Secrets: SNOW_INSTANCE, SNOW_USER, SNOW_PASS
Add the ServiceNow GitHub Action step in your workflow YAML before deployment
Configure change approval policies in ServiceNow (Assignment Rules, Approval Rules)
Verify pipeline execution records appear in ServiceNow DevOps dashboard

Phase 3

Pipeline Development — Weeks 5–7

YAML authoring for AWS, Azure, OCI deployments with built-in security scanning. CSF: Protect ISO: A.12

Phase 4

ServiceNow Integration — Weeks 8–9

Why Businesses Will Benefit

PES builds CI/CD pipelines that integrate with your existing toolchain — GitHub, ServiceNow, Jenkins, Terraform. Our pipelines include automated security scanning at build time, change management approval gates via ServiceNow, and Day 2 Operations monitoring from day one. The Dev→Stage→UAT→Prod lifecycle runs with zero manual deployment steps. Plus, we provide YAML example files you can review, extend, and own.
