These EC2 instances have internet access, either through a network address translation (NAT) gateway or an internet gateway.These EC2 instances were launched from an Amazon Machine Image (AMI) or an AMI that you created from an Amazon AMI.You have one or more EC2 instances running a Windows operating system that you would like to patch.Here are just a few of the features of Systems Manager:įor the purposes of this Patch Manager walkthrough, we assume the following about your AWS environment: Patch Manager is part of the larger AWS Systems Manager product, which offers many other features for managing your systems in the AWS cloud and on-premises. Patch Manager can be used to apply updates to both your cloud systems hosted in Amazon EC2 and (in hybrid environments) your on-premises systems. Patch Manager acts as a trigger to initiate patching or compliance activities, and uses the built-in patching mechanisms for your client operating system.

Patch Manager allows you to deploy patches on a schedule of your choosing, and view compliance status.

Instead, an organization can focus on what makes their situation unique and deploy patching more easily without all of the undifferentiated heavy lifting of traditional configuration management software. Patch Manager is a cloud-native managed service, meaning that organizations no longer have to deal with the scalability issues and complex application management associated with operating a complex configuration management solution. We walk you through setting up your first Patch Manager configuration to patch your Windows-based Amazon Elastic Compute Cloud (Amazon EC2) instances that you have already deployed. This post is a primer on Patch Manager for systems administrators who are familiar with the SCCM product. We find that many customers are looking to move away from Microsoft System Center Configuration Manager (SCCM) for patching, and move towards an AWS-native solution using AWS Systems Manager Patch Manager. As organizations migrate their traditional data centers and applications into the AWS cloud, they also want to modernize their patching mechanisms in order to reap the benefits of operating in the cloud.
