This page provides an overview of QMCLOUD and the various components.
QMCLOUD allows a user to compose, edit, and deploy cloud infrastructure resources with minimal programming experience. Once a user deploys the desired state, QMCLOUD generates the required code automatically on behalf of the user and uses a third-party software (Pulumi) to initiate the deployment of resources.
QMCLOUD stores various configuration details in its internal database about a stack and the cloud resources that are deployed including properties, connections, state of deployment.
QMCLOUD currently relies on the Pulumi service to store the current state of the cloud infrastructure resources. The state is a set of metadata about the infrastructure so that it can managed appropriately. Each stack (a unit of infrastructure) has its own state, and state is how QMCLOUD and Pulumi know when and how to create, read, delete, or update cloud resources.
Note - Please refer to this link on what is Pulumi service, and state and how it stores the metadata. https://www.pulumi.com/docs/intro/concepts/state/
QMCLOUD consists of the following logical components:
- Stack, Stack group and Stack profile
- Users, Permissions, and Roles
The following diagram depicts the high-level structure and components of QMCLOUD and their relationships.
