Streamlining Patch Management: Cloud-Native Solutions for Multi-Cloud Environments

Ram Kadari, Lead Devops II

Cloud-native solutions can integrate seamlessly with existing cloud environments and offer unique cost and management advantages. Although cloud-native patch management might seem like a straightforward service for companies with a limited number of customers, it can become quite complicated for global enterprises. Handling a large number of customers across various cloud platforms often complicates the patching process.

Now, envision a solution that seamlessly integrates with customers' cloud environments, offering streamlined patching across diverse platforms without the complexity and overhead of managing each customer's patching individually.

That's the vision. To have a centralized tool that simplifies and streamlines the entire patch management process.

Problem

As enterprises grow and expand globally, managing patch deployments across diverse customers and cloud environments becomes increasingly complex. Setting up patch management for multiple customers and managing them centrally presents its own challenges.

The absence of automation for these tasks leads to inefficiencies in onboarding, scheduling and patching across different regions and time zones, requiring additional time and effort from IT teams.

Challenges

Multi-Cloud Complexity

  • Different cloud platforms may have unique patching mechanisms, tools, and policies, making it difficult to standardize the patch management process across multiple environments.
  • Lack of unified visibility across clouds complicates tracking, monitoring, and reporting on patch compliance and success rates.

Multi-Region and Multi-Time Zone Scheduling

  • Coordinating patches across customers in various geographical regions requires precise scheduling to accommodate different time zones and business hours.

Minimal Disruption

  • Ensuring minimal disruption for customers in different regions can be difficult without a highly automated patching system that adapts to varying time zones and business needs.

Onboarding New Customers

  • Onboarding new customers to the patching process manually can be time-consuming, particularly in large-scale global operations.
  • Each new customer may have unique patching requirements and security policies, adding to the complexity of standardizing the process.

Compliance and Security

  • Keeping track of patch compliance across multiple clients and ensuring all systems are secure can be overwhelming without automation.

Patch Window Conflicts

  • Managing conflicting maintenance windows for multiple clients while adhering to their individual business needs, workloads and uptime requirements can create challenges, particularly when patching must occur within a narrow window.

The Ollion Solution

Ollion provides a tailored approach to managing patch management across multiple clouds and customers with a comprehensive solution. A solution that is simple to implement and manage, providing all the customizable cloud options without the usual complexity.

Our service emphasizes security and compliance, delivering configurations specifically designed to meet the unique needs of each client. This ensures that your organization can effectively leverage cloud-native services while maintaining a secure and compliant infrastructure.

The automation of patch management offers several advantages, such as enabling flexible multi-region patching from a single account, configuring patching based on different time zones. Additionally, automation significantly simplifies the onboarding process for new customers, drastically reducing the time and effort needed to become operational.

Key elements of the Automation include

Terraform Configuration

As the core element of the solution, Terraform handles the entire setup and orchestration process. It is used to provision and manage essential cloud resources, including maintenance windows, S3 and GCS buckets, patch baselines, Lambda/Cloud Functions and cloud schedulers. The flexible Terraform code enables the implementation of edge patch configurations offered by cloud providers and can simplify the process of updating key elements of the automation at a later stage.

Smooth Onboarding of New Customers / Accounts

The automation solution is designed for easy onboarding, enabling new customers and accounts to be integrated quickly and efficiently. This reduces setup time and allows organizations to become operational in a fraction of the time, enhancing overall user experience.

GitHub Repository

All automation code and cloud specific triggering mechanisms are stored in a GitHub repository.

CSV-Input file

A single CSV file can handle multiple patch jobs with various patch configurations suitable for different operating systems

Alerting

Integration with notification services (e.g., SNS, SLACK, SES) enables customers/platforms to be notified about the status of patch jobs, ensuring they stay informed throughout the processes and the maintenance windows.

Reporting

Automated reporting features send detailed reports directly to emails, summarizing patch statuses, actions taken and any issues encountered, making it easy to keep track of patching.

Multi-region Handling & Timezone Capabilities

The solution can be deployed across multiple regions, with support for configuring patch schedules based on different time zones, ensuring a consistent patching process no matter where your infrastructure is located.

CSV-Based Triggering Mechanisms

Patch jobs can be initiated through CSV-based inputs, allowing for easy customization and control over which resources need patching, providing a user-friendly way to manage updates at scale.

Inventory Management

Customized Inventory automation that provides visibility into available packages and their count, giving organizations a clear view of what is installed across their environments.

Value Proposition to the Organization

The benefits of migrating to cloud-native patch management and automating the process for an organization handling multiple customers across different clouds can be articulated as follows:

Enhanced Efficiency and Productivity

  • Faster Onboarding: Streamlined onboarding processes for new customers across multiple clouds significantly reduce the time required to get operational, enabling the organization to scale faster and increase productivity.

Greater Flexibility and Scalability
