ARM provides distinct advantages and benefits over ASM, which are as follows:
- Grouping: ARM allows grouping of resources together in a logical container. These resources can be managed together and go through a common life cycle as a group. This makes it easier to identify related and dependent resources.
- Common life cycle: Resources in a group have the same life cycle. These resources can evolve and be managed together as a unit.
- Role-Based Access Control: Granular roles and permissions can be assigned to resources providing discreet access to users. Users can also have only those rights that are assigned to them.
- Deployment support: ARM provides deployment support in terms of templates enabling DevOps and Infrastructure as Code (IAC). The deployments are faster, consistent, and predictable.
- Superior technology: Cost and billing of resources can be managed as a unit. Each resource group can provide their usage and cost information.
- Manageability: ARM provides advanced features, such as security, monitoring, auditing, and tagging, for better manageability of resources. Resources can be queried based on tags. Tags also provide cost and billing information for resources tagged similarly.
- Migration: Easier migration and updating of resources within and across resource groups.
