Project Overview

 

Overview

A global technology services company was facing challenges maintaining consistent security patching across its multi-environment infrastructure (Production, Staging, Dev, and DR).

Manual patch operations took several hours, required weekend maintenance windows, and often resulted in configuration drift between servers.

The client approached us to design and implement an enterprise-grade Patch Management Automation solution using Red Hat Ansible Automation Platform (AAP) to standardize, automate, and orchestrate patching across 100+ Linux servers.

Objectives

  • Centralize and automate OS patching across all environments
  • Reduce manual work and maintenance window duration
  • Ensure consistent patching with zero configuration drift
  • Improve compliance & security posture
  • Provide a repeatable, fully auditable patching workflow
  • Enable teams to run patches safely on-demand or on schedule

What We Delivered

1. Enterprise Automation Architecture

We designed a scalable automation architecture using:

  • Ansible Automation Platform (AAP 2.x)
  • Execution Nodes distributed across environments
  • Automation Mesh for secure communication
  • Dynamic Inventories synced from NetBox
  • Credential Store with RBAC
  • Git-backed Project Repositories (GitOps Model)

This ensured centralized control, secure credential handling, and multi-environment orchestration.

2. Automated Patch Management Playbooks

We developed fully automated patching workflows for:

  • RHEL / CentOS / Rocky Linux
  • Ubuntu / Debian
  • Amazon Linux
  • Oracle Linux

Playbooks included:

  • Pre-checks (disk, CPU, RAM, process audit)
  • Service dependency validation
  • Patch installation logic
  • Kernel update detection
  • Smart reboot logic (only if required)
  • Post-patch validation & health check
  • Reporting to Slack/Email

This eliminated human error and provided consistent, repeatable patch cycles.

3. Environment-Specific Patch Pipelines

Using AAP Job Templates & Workflows, we implemented:

  • Dev → Staging → Production patch pipelines
  • Approval gateways for Production
  • Scheduled maintenance windows
  • Automated rollback triggers on failure
  • Compliance reports exported to PDF/CSV

This enabled the customer to run patching across environments with a single click or fully automated schedule.

4. Security & Compliance Hardening

We strengthened the overall security posture by implementing:

  • RBAC roles for DevOps, SRE, and SecOps
  • Encrypted credentials with Vault
  • Logging & auditing via Automation Controller
  • Immutable Git-based configuration
  • CIS Benchmark pre-checks
  • Automated drift detection

As a result, the client achieved 95% patch compliance in the first month.

Results

✔ 80% reduction in time spent on patching
✔ 100+ servers patched automatically with zero manual steps
✔ 90% reduction in human error & configuration drift
✔ Full audit trail for security & compliance teams
✔ Standardized patch workflow across multiple environments
✔ Dramatically improved security posture & response time to CVEs

Client Feedback

“Our patching process used to take us an entire weekend every month.
After implementing the Ansible Automation Platform, we run patches across all environments with one click.
This automation has massively improved our security and freed up valuable engineering hours.”
