Q: What is Amazon Systems Manager OpsCenter?

OpsCenter is a Systems Manager capability that provides a central location where operations engineers, IT professionals, and others can view, investigate, and resolve operational issues related to their environment. OpsCenter is designed to reduce mean time to resolution for impacted Amazon Web Services and hybrid cloud resources. OpsCenter aggregates and standardizes operational issues, referred to as OpsItems, while providing contextually relevant data that helps with diagnosis and remediation. Information includes Config changes, Amazon CloudTrail logs, resource description, Amazon CloudWatch alarms, related OpsItems, and related resources. You can use our public APIs to create OpsItems from any source or use OpsItems integrated with Amazon CloudWatch Events. This means you can configure CloudWatch to automatically create OpsItems for any Amazon Web Services service that publishes events to CloudWatch Events.

You can create the following types of OpsItems leveraging manual or automated configurations:

  • Resource failures, such as an Amazon EC2 Auto Scaling group failure to launch an instance or a Systems Manager Automation execution failure
  • Resource performance issues, such as a throttling event for Amazon DynamoDB or degraded Amazon EBS volume performance
  • Health alerts from various Amazon Web Services services, such as scheduled maintenance for an RDS DB instance or EC2 instance
  • Resource state changes, such as an Amazon EC2 instance state change from running to stopped
  • Or any other work item that needs someone’s attention

Q: What is an OpsItem?

An Opsitem is an Amazon Web Services resource-related operational event which needs a user’s attention, and potentially, an investigation and resolution. It could be a resource-related failure, a maintenance notification, security alert, or a performance issue. An Opsitem includes relevant information that aids with investigation and resolution of the underlying event, such as impacted resources, similar past events, and recommended runbooks. High EC2 instance CPU utilization, CodeDeploy Deployment Failed, or EC2 Automation Execution failed are some examples of common OpsItems.

Q: What are the benefits of using OpsCenter?

OpsCenter enables users to reduce their mean time to resolution (MTTR) for operational issues, in some cases by over 50%. OpsCenter enables standardization and aggregation of operational issues (aka OpsItems) across various resources in a single place. Additionally, it brings together contextual information and operational tooling required to investigate and remediate issues. This reduces the time it takes engineers to navigate different tools to get relevant information. Working from a single location also minimizes the chances of manual errors, and reduces training time for newly hired engineers.

Q: Who should use OpsCenter?

Medium to large enterprises, who use multiple Amazon Web Services services for their infrastructure needs, can leverage OpsCenter to manage their day-to-day operations. Additionally, Managed Service Provider (MSP) partners can also leverage OpsCenter as they manage infrastructure on behalf of other Amazon Web Services customers. MSP customers can have a read-only role for better transparency into the MSP’s day-to-day operations.

Primary users of the service will be operations engineers, such as DevOps engineers and IT service desk professionals.

Q: How is OpsCenter different from a Case Management system?

OpsCenter is designed to complement your existing case management systems. You can integrate OpsCenter into your existing case management system by using public API actions. You can also maintain manual lifecycle workflows in your current systems and use OpsCenter as an investigation and remediation hub.

For Linux you run any Shell command or script, and remotely update the installed agent.

Q: Can I create my own commands?

Yes. Run Command allows you to easily create custom commands to perform common tasks required for your environment.

Q: What other types of commands or script can I run?

You can run any command or script that you can type into a command window on your EC2 instances.

Q: Can I send the same command to multiple EC2 instances at once?

Yes. You can easily issue a command to a fleet of instances by providing a list of instances when issuing a command.

Q: Can I retrieve the history of commands run against my instances?

Yes. Run Command keeps the output for each command for 30 days. In addition, you can have Run Command store a copy of all log files in Amazon S3 or capture the output of your commands using Amazon CloudTrail.

Q: Can I control who can execute a command?

Yes. Using the published Amazon Identity and Access Management (IAM) permissions and policies, you can control who has access to execute commands or documents on specific instances. For example, you can specify an IAM user who can run PowerShell commands, but not join an instance to a domain. Another IAM user can only be given access to run a very specific command like restarting services, giving you the flexibility to specify how much access any given user can have.

Q: Can I check the status of a running command?

Run Command provides the status of a command for each instance it is running on. All of this can be retrieved from the Amazon CLI, SDK, or the EC2 Management Console.

State Manager

Q: What is State Manager?

State Manager automates the process of defining and maintaining a consistent configuration of OS and applications across your entire fleet of systems. For example – configuring and enforcing firewall policies, keeping anti-malware definitions current. Through reapplication of your configuration policies, State Manager ensures that your systems are always compliant with your enterprise policies.

Q: Why should I use State Manager?

Businesses are moving towards automated IT with applications across environments and locations, including on Amazon Web Services and on-premises data centers. However, ensuring that the infrastructure powering your applications is consistent is a challenge. State Manager allows you create policies, reapply these policies to prevent configuration drift, and monitor the status of your intended state.

Q: How do I create my policies?

Policies can be easily created through Systems Manager Documents. In addition, you also have predefined configurations that you can use for installing applications, joining instances to domain and so on.

Q: What are the targets that can be configured?

You have the flexibility to target instances or tags. This means you have the flexibility to have specific configurations for groups of instances such as webservers.

Patch Manager

Q: What is Patch Manager?

Patch Manager is an automation-focused patching service which makes it easy for customers to keep their Windows instances up to date. Patch Manager helps you streamline your patching process through the implementation of built in best practices, such as maintenance windows and dynamic patch approval policies.

Q: How do I specify when I would like to patch an instance?

You use Maintenance Windows to define when patching occurs. Maintenance Windows are a new feature of EC2 which provide you the ability to define one or more recurring windows of time during which it is acceptable for your own maintenance to occur. By defining these windows and associating your instances with them, it is easier for you to ensure that any maintenance activities you perform on your instances which may impact the availability of a workload is done so during a well-defined window of time. Maintenance windows make it easy to schedule when you would like your own Run Command tasks to occur.

Q: How do I customize the patching process?

Patch Manager leverages Run Command to provide a fully automated patching process. While Patch Manager provides a pre-built Run Command document, you can easily customize the patching process by writing your own Run Command Document. For example, you can stop an NT service before rolling out the patches.

Q: What types of patches can I install with the Patch Manager?

Patch Manager supports the patching of Windows based instances, and provides the ability to select and deploy patches for Windows Server 2008 through Windows Server 2016 and Windows 7 – Windows 10.

Q: How do I pick the patches I want to install?

Patch Manager provides you with the ability to create Patch Baselines, which define the set of patches you have approved or blocked for deployment to your instances. In a Patch Baseline, you can select patches by the products (e.g. Windows Server 2008, Windows Server 2012, etc.), categories (e.g. Critical Updates, Security Updates, etc.) and severities for which you would like to review patches for deployment. For each category selected, you can then define a schedule on which the contained patches will be automatically approved for distribution. In addition to the rules, you can also specify a whitelist and blacklist of patches which indicate patches which are to be installed or blocked respectively. At the time of patching, Patch Manager will assess targeted instances for only the patches that have been approved prior to that point in time.

Q: How do I track the compliance levels of my instances?

With Patch Manager you can view patch compliance information which tells you the detailed results of the patching process. From the EC2 Management Console or API you can easily get aggregate compliance details per instance. In addition, you drill in further and for each instance you can determine which patches are installed, missing, not applicable, and which failed to install.


Q: What is Inventory?

The Inventory capability in Systems Manager provides visibility into an instance's software catalog and configuration. You can set up Inventory to gather detail on a variety of instance attributes such as installed applications, Amazon Web Services components and agents, network configuration, OS details, and more. Then use the powerful query feature to assess compliance and identify instances in need of remediation across your fleet.

Q: Who should use Inventory?

IT administrators and devops professionals will find this capability useful in understanding the configuration and composition of their fleets. Users can quickly determine which instances are missing a patch or are running an outdated application version. Similarly admins can run licensing audits to understand software usage. The net result is that systems administrators are better able to troubleshoot issues and assess security posture.

Q: Can I customize the information gathered by the Inventory?

Yes, you can create your own custom Inventory types and effectively extend Inventory's schema. For example, you can configure your instance to gather additional OS and CIM details, or record items like rack location and in-service date for on-premise servers.

Q: How can I track changes to my configuration over time?

Using Amazon Config, you can monitor an instance's compliance with a desired configuration through Config Rules. This capability allows security experts and compliance auditors to have a complete audit trail of instance configuration changes, as well as receive proactive notifications in the event of non-compliance.


Q: What is Automation?

The Automation capability in Systems Manager simplifies the process of building and maintaining Amazon Machine Images (AMIs). This provides you a repeatable process to apply patches, application updates, and other changes to your AMIs.

Q: What tasks can I automate?

AMI maintenance is greatly simplified by Automation feature of Systems Manager, allowing you to patch, update agents, or bake-in applications using a streamlined, repeatable, and auditable process.

Parameter Store

Q: What is Amazon Systems Manager parameter store?

Amazon 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 Amazon Key Management Service (KMS), allowing you to automatically encrypt the data you store. You can also control user and resource access to parameters using Amazon Identity and Access Management (IAM). Parameters can be referenced through other Amazon Web Services services, such as Amazon Elastic Container Service, Amazon Lambda, and Amazon CloudFormation.

Q: Why should I use Amazon Systems Manager parameter store?

It is a best practice to store configuration data and secrets separately from your code. You can use Amazon Systems Manager parameter store to quickly store and reference configuration and sensitive information. Rather than storing data in config files or referencing them in plain text, you can store and obtain this information in your applications or scripts. Additionally, you control who has access to parameters so that only the right set of users has access to the appropriate information.

Q: How do you store sensitive data?

A secure string is any sensitive data that needs to be stored and referenced in a secure manner. If you have data that you do not want users to reference in clear text or have access to data that can be tampered with or misused, you should use secure strings in Amazon Systems Manager parameter store. You can encrypt your sensitive data using your own Amazon Key Management Service (KMS) key or your user account default key provided by Amazon KMS.

Q: What services can I reference my parameters?

You can easily reference your parameters across Amazon Web Services services such as Amazon Elastic Container Service, Amazon Lambda, and Amazon Systems Manager, or any service through which you can use the Amazon Systems Manager parameter store APIs.

Q: Can I track usage and provide access control to specific parameters?

Yes. You can provide granular access control through customized permissions to users and resources (such as instances) for parameters access using Amazon Identity and Access Management (IAM). This means you can control who can access which parameter on what resource. You can also set up Amazon CloudWatch Events rules based on parameter change events. Additionally, you can also track and audit parameter API calls using Amazon CloudTrail.

Q: Can I track changes to parameters?

Yes, you can see history of parameter changes. You can also use versions that are automatically incremented upon change to look up specific parameter value bases on its version.

Q: Can I store hierarchical data as parameters?

Yes, you can use a hierarchical structure to store parameters. You can also control and audit access at every level of the hierarchy.

Q: Can I receive notifications upon changes to parameter values?

Yes, you can set up Amazon CloudWatch and Amazon Simple Notification Service (SNS) notifications for individual parameter values, and receive notifications upon change.

Q: What is the difference between Secrets Manager and Parameter Store?

Amazon Secrets Manager is a service to manage the lifecycle for the secrets used in your organization centrally including rotation, audit, and access control. Secrets Manager helps you meet your security and compliance requirements by enabling you to rotate secrets automatically. Secrets Manager offers built-in integration for MySQL, PostgreSQL, and Amazon Aurora on Amazon RDS that's extensible to other types of secrets by customizing Lambda functions.

Amazon Systems Manager Parameter Store provides secure, hierarchical storage for configuration data management, which can include secrets. Data such as database connection strings, passwords, and license codes can be stored as parameter values and can be audited and access controlled. Values stored can be either plain text or encrypted data. You can then reference values by using the unique name of the parameter. You can reference Systems Manager parameters to build generic configuration and automation scripts for use across Amazon Web Services services such as Amazon ECS and Amazon CloudFormation.
