Systems Manager Introduction

AWS Systems Manager is a service that helps you manage your AWS resources and applications in a centralized and secure way. It allows you to view operational data from multiple AWS services, automate tasks across your AWS resources, and troubleshoot issues quickly and efficiently.

What can you do with AWS Systems Manager?

AWS Systems Manager provides you with four main categories of features:

• Application management: You can use Application Manager to group your AWS resources into logical applications and clusters, and monitor their performance and health. You can also use AppConfig to deploy configuration changes to your applications without disrupting them. And you can use Parameter Store to store and manage configuration data such as passwords, database strings, and license codes securely.

• Change management: You can use Automation to create workflows that automate common or complex tasks such as patching, backup, or deployment. You can also use Change Manager to review and approve changes before they are applied to your resources. And you can use Maintenance Windows to schedule tasks to run during predefined time windows.

• Node management: You can use Fleet Manager to manage your EC2 instances and on-premises servers from a single console. You can also use Session Manager to access your instances remotely without using SSH keys or bastion hosts. And you can use Patch Manager to scan and apply patches to your instances automatically.

• Operations management: You can use Explorer to aggregate and analyze operational data from various AWS services such as CloudWatch, CloudTrail, and Config. You can also use OpsCenter to view and manage operational issues across your resources. And you can use Incident Manager to create incident response plans and automate actions to resolve incidents faster.

How does AWS Systems Manager work?

AWS Systems Manager works by using the Systems Manager Agent (SSM Agent), which is a software that runs on your instances and servers. The SSM Agent communicates with the Systems Manager service and performs actions on your behalf. You can access Systems Manager through the AWS Management Console, the AWS CLI, or the AWS SDKs.

To use Systems Manager, you need to have an AWS account and an IAM user, group, or role with the required permissions. You also need to install and configure the SSM Agent on your instances and servers. You can then use Systems Manager to perform various tasks on your resources.

Why should you use AWS Systems Manager?

AWS Systems Manager offers you several benefits, such as:

• Visibility: You can get a comprehensive view of your AWS resources and applications in one place. You can also monitor their performance, health, and compliance status easily.
• Control: You can manage your AWS resources and applications securely and consistently. You can also enforce policies and standards across your resources.
• Efficiency: You can automate common or complex tasks and reduce manual errors. You can also save time and costs by optimizing your resource utilization.
• Reliability: You can troubleshoot issues faster and minimize downtime. You can also improve your security posture and resilience by applying patches and updates regularly.
