AWS Systems Manager allows you to centralize operational data from multiple AWS services and automate tasks across your AWS resources. You can create logical groups of resources such as applications, different layers of an application stack, or production versus development environments. With Systems Manager, you can select a resource group and view its recent API activity, resource configuration changes, related notifications, operational alerts, software inventory, and patch compliance status. You can also take action on each resource group depending on your operational needs. Systems Manager provides a central place to view and manage your AWS resources, so you can have complete visibility and control over your operations.
OpsCenter provides a central location where operations engineers and IT professionals can view, investigate, and resolve operational issues related to any AWS resource. OpsCenter aggregates and standardizes operational issues, referred to as OpsItems, while providing contextually relevant data that helps with diagnosis and remediation. Engineers working on an OpsItem get access to information such as:
- Event, resource and account details
- Past OpsItems with similar characteristics
- Related AWS Config changes
- AWS CloudTrail logs
- Amazon CloudWatch alarms
- Stack information
- Other quick-links to access logs and metrics
- List of runbooks and recommended runbooks
- Other information passed to OpsCenter through AWS services
This information helps engineers to investigate and remediate operational issues faster. Engineers can use OpsCenter to view and address issues using the Systems Manager console or via the Systems Manager OpsCenter APIs.
Resource groups are a way to create a logical group of resources associated with a particular workload such as different layers of an application stack, or production versus development environments. For example, you can group different layers of an application, such as the frontend web layer and the backend data layer. Resource groups can be created, updated, or removed programmatically through the API.
AWS Systems Manager automatically aggregates and displays operational data for each resource group through a dashboard. Systems Manager eliminates the need for you to navigate across multiple AWS consoles to view your operational data. With Systems Manager you can view API call logs from AWS CloudTrail, resource configuration changes from AWS Config, software inventory, and patch compliance status by resource group. You can also easily integrate your AWS CloudWatch Dashboards, AWS Trusted Advisor notifications, and AWS Personal Health Dashboard performance and availability alerts into your Systems Manager dashboard. Systems Manager centralizes all relevant operational data, so you can have a clear view of your infrastructure compliance and performance.
AWS Systems Manager collects information about your instances and the software installed on them, helping you to understand your system configurations and installed applications. You can collect data about applications, files, network configurations, Windows services, registries, server roles, updates, and any other system properties. The gathered data enables you to manage application assets, track licenses, monitor file integrity, discover applications not installed by a traditional installer, and more.
AWS Systems Manager allows you to safely automate common and repetitive IT operations and management tasks across AWS resources. With Systems Manager, you can create documents that specify a specific list of tasks or use community published documents. These documents can be scheduled in a maintenance window, triggered based on changes to AWS resources through Amazon CloudWatch events, or executed directly through the AWS Management Console, CLIs, and SDKs. You can track the execution of each step in the documents as well as require approvals for each step. You can also incrementally roll out changes and automatically halt when errors occur.
AWS Systems Manager provides you safe, secure remote management of your instances at scale without logging into your servers, replacing the need for bastion hosts, SSH, or remote PowerShell. It provides a simple way of automating common administrative tasks across groups of instances such as registry edits, user management, and software and patch installations. Through integration with AWS Identity and Access Management (IAM), you can apply granular permissions to control the actions users can perform on instances. All actions taken with Systems Manager are recorded by AWS CloudTrail, allowing you to audit changes throughout your environment.
AWS Systems Manager provides a browser-based interactive shell and CLI for managing Windows and Linux EC2 instances, without the need to open inbound ports, manage SSH keys, or use bastion hosts. Administrators can grant and revoke access to instances through a central location by using AWS Identity and Access Management (IAM) policies. This allows you to control which users can access each instance, including the option to provide non-root access to specified users. Once access is provided, you can audit which user accessed an instance and log each command to Amazon S3 or Amazon Cloud Watch Logs using AWS CloudTrail.
AWS Systems Manager helps you select and deploy operating system and software patches automatically across large groups of Amazon EC2 or on-premises instances. Through patch baselines, you can set rules to auto-approve select categories of patches to be installed, such as operating system or high severity patches, and you can specify a list of patches that override these rules and are automatically approved or rejected. You can also schedule maintenance windows for your patches so that they are only applied during preset times. Systems Manager helps ensure that your software is up-to-date and meets your compliance policies.
AWS Systems Manager lets you schedule windows of time to run administrative and maintenance tasks across your instances. This ensures that you can select a convenient and safe time to install patches and updates or make other configuration changes, improving the availability and reliability of your services and applications.
AWS Systems Manager helps you securely distribute and install software packages, such as software agents. Systems Manager Distributor allows you to centrally store and systematically distribute software packages while you maintain control over versioning. You can use Distributor to create and distribute software packages and then install them using Systems Manager Run Command and State Manager. Distributor can also use Identity and Access Management (IAM) policies to control who can create or update packages in your account. You can use the existing IAM policy support for Systems Manager Run Command and State Manager to define who can install packages on your hosts.
AWS Systems Manager provides configuration management, which helps you maintain consistent configuration of your Amazon EC2 or on-premises instances. With Systems Manager, you can control configuration details such as server configurations, anti-virus definitions, firewall settings, and more. You can define configuration policies for your servers through the AWS Management Console or use existing scripts, PowerShell modules, or Ansible playbooks directly from GitHub or Amazon S3 buckets. Systems Manager automatically applies your configurations across your instances at a time and frequency that you define. You can query Systems Manager at any time to view the status of your instance configurations, giving you on-demand visibility into your compliance status.
AWS Systems Manager provides a centralized store to manage your configuration data, whether plain-text data such as database strings or secrets such as passwords. This allows you to separate your secrets and configuration data from your code. Parameters can be tagged and organized into hierarchies, helping you manage parameters more easily. For example, you can use the same parameter name, "db-string", with a different hierarchical path, "dev/db-string” or “prod/db-string", to store different values. Systems Manager is integrated with AWS Key Management Service (KMS), allowing you to automatically encrypt the data you store. You can also control user and resource access to parameters using AWS Identity and Access Management (IAM). Parameters can be referenced through other AWS services, such as Amazon Elastic Container Service, AWS Lambda, and AWS CloudFormation.
