AWS Systems Manager provides a unified user interface for identifying and resolving operational issues in AWS applications and resources including Amazon Elastic Compute Cloud (EC2), Amazon Relational Database Service (RDS), Amazon Elastic Container Service (ECS), and Amazon Elastic Kubernetes Service (EKS).
Furthermore, it provides a single and uniform way to acquire operational insights and perform routine management tasks for numerous AWS services. AWS Systems Manager can be used to run routine operations, track the development, test, and production environments, and take proactive action in the case of an event or other operational incident.
Features
Run Command
By integrating with AWS Identity and Access Management, SSM provides significantly more control over managing remote command executions. For auditing purposes, it keeps track of remote commands. We can also generate SSM documentation for commands and use them frequently.
Documentation
SSM comes with a number of pre-made documents that may be used with Run Commands, Automation, and States Manager. We can also create our own unique documents. SSM Document permissions are connected with AWS IAM, allowing us to use AWS IAM policies to manage who has execution privileges on which documents.
Secure
SSM agent runs as root on the instance so that we can better analyze its security posture.
Compliance
This is an SSM reporting method that updates us if the instances are patch baseline or States Manager association compliant. Therefore, this capability can drill down into issues and resolve them using SSM Run commands or Automation.
Concurrency
To run commands or automation documents in parallel, SSM lets you to specify a percentage or count of target instances. We can also halt executions if the number of target instances throwing errors reaches a certain threshold.
Managing Patch
One of the most significant features for keeping our environment up to date with freshly published patches is the patchmanagement tool.
State Manager
Things change over time, thus maintaining compliance with the best security and operating principles in the environment is a challenge. State Manager makes it simple to keep our application environment in the desired state by allowing to run a collection of commands using SSM documents on a regular basis.
