Versions:
Amazon SSM Agent 3.3.4108.0 is a lightweight systems-management component published by Amazon Web Services that installs on Amazon EC2 instances, on-premises servers, edge devices, and virtual machines to enable secure, API-driven remote administration at scale. Acting as the local executor for the AWS Systems Manager service, the agent listens for instructions delivered through the Amazon Message Gateway Service (ssmmessages endpoints, with legacy ec2messages endpoints still used in Regions launched before 2024), carries out requested tasks—such as applying patches, running shell scripts, changing configuration states, or gathering inventory—and then returns status and execution metadata to the console. Typical use cases include automating maintenance windows across large fleets, distributing parameter-store secrets, enforcing consistent OS baselines, troubleshooting instances without SSH or RDP, and streaming logs to Amazon CloudWatch for centralized auditing. The current stable release, version 3.3.4108.0, is one of ten sequentially maintained builds that incorporate security fixes, new SSM document support, and performance refinements while preserving backward compatibility with existing Documents and Session Manager workflows. Because the agent is essential for instance health and compliance visibility, AWS automatically pre-installs it on most Amazon Linux and Windows AMIs, yet administrators can also self-deploy the same signed binaries to VMware, Hyper-V, or bare-metal hosts outside the cloud, creating a hybrid environment managed through a single Systems Manager dashboard. Amazon SSM Agent is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
