I$\text{'}$m having trouble understanding system sequence diagrams. Need assistance with a visual depiction of a system sequence diagram base on the following parameters:

Actor: The DevOps Engineer is a producer and consumer of the systems with an ability to start and respond.

Systems$/$Devices:

Version Control System $($e$.$g$.,$ GitHub$)$to stores IaC templates. IaC Tool $($e$.$g$.,$ Ansible$)$for provisions infrastructure. Cloud Provider $($e$.$g$.,$ AWS$)$ to deploy infrastructure resources in server. Validation Tool Jenkins or script which tests and validates the configurations. Monitoring Tool $($e$.$g$.,$ Prometheus$)$ it is the tool that accumulates metrics and it monitors a given system.

Explanation:

This step will guarantee that the hosting elements of the system have been properly identified they lie within the flow of the activity diagram developed.

Map Interactions to SSD

Pull IaC Templates:

System will responds with the template files. Received templates are submitted by the DevOps Engineer to the IaC Tool. After that the IaC Tool will be communicates with the Cloud Provider for providing resources. IaC templates from Version Control Systeme.git$).$ System will responds with the template files.

Provision Infrastructure:

DevOps Engineer sends the templates to IaC Tool. Then IaC Tool will be interacts with Cloud Provider for deploying resources. Last of all, the Cloud Provider gives the go ahead on the deployment.

Explanation:

This step reflects the provisioning of resources and infrastructure setup.

Validation, Monitoring, and Handling Failures

Validation:

DevOps Engineer will instructs the Validation Tool for checking configurations. If any errors occur, system retries using the IaC Tool.

Monitoring:

$$

After validation, the Monitoring Tool provides the results of performance measurements.Failures trigger will recovery the processes from IaC Tool.

$$

Stop:

The workflow finishes when the system is steady or when the certain workflow has been stopped.

Explanation:

In this step main theme is validating, optimizing, and ensuring the system$$s reliability.
