Automated Patch Solution for EC2

Visionet's automated patching solution is a fully serverless and automated AWS solution designed to handle patch management for EC2 instances based on user-defined schedules. This solution leverages a suite of AWS services including AWS Systems Manager, AWS Lambda, Amazon EventBridge, and Amazon CloudWatch to provide robust, reliable, and efficient patching workflows for EC2 environments without any infrastructure management overhead.

With this solution, patching is safe, automated, and straightforward. Before initiating any patching operation, the solution creates a backup of the instance as an Amazon Machine Image (AMI), ensuring a secure restore point in case of any issues during the patching process. These backups are managed by a retention policy that automatically deletes older AMIs, saving on storage costs and maintaining only the most recent backups for each instance.

Once the backup is complete, it proceeds with patching each instance according to the schedule and policies set by the user. After patching is done, the process (orchestrated through the use of SSM Automation documents) restores each EC2 instance to its original state, ensuring that applications and workloads continue running smoothly. Detailed monitoring is available throughout the process via Amazon CloudWatch, allowing users to view logs, track patching progress, and receive alerts in case of any errors or exceptions during the operation.

Through this, Visionet simplifies the patch management lifecycle with custom schedules, automatic backups, reliable rollbacks, and complete visibility into the patching process, enabling a secure, cost-effective, and operationally efficient EC2 patch management solution. Deployment and onboarding has been made extremely simple by using CloudFormation templates which can be customized using user-input parameters to set multiple configurations as desired.
