New High Availability agents for Azure environment
(Linux only)
Veritas has introduced the following high availability agents for Azure:
AzureDisk agent
AzureIP agent
AzureDNSZone agent
AzureAuth agent
These agents are bundled with the product.
The AzureDisk agent brings online, takes offline, and monitors the managed and un-managed Azure data disks. It attaches the managed and un-managed data disks to a virtual machine of the same or different resource group. The AzureDisk agent uses Azure Python SDK to determine whether the Azure data disks are attached to the Azure virtual machines or not.
The AzureIP agent manages the networking resources in an Azure environment. The agent uses Azure Python APIs to associate IP resources in an Azure VM.
The agent does the following:
Gets the NIC details, creates the configuration, and associates or disassociates the private IP address.
Associates or disassociates the public IP address, with the private IP address.
Manages the route table entries of overlay IP, for failing over across the subnets.
The AzureDNSZone agent monitors and updates the host name to resource record mapping. This agent does the mapping for the Azure DNS domain when failing over to the nodes across the subnets or the regions.
AzureDNSZone agent provides DNS-based traffic routing and failover.
Use this agent, if the resource records need to be dynamically added and deleted from the domain during failover. This agent updates the new resource record mappings while failing over, and allows the clients to connect to the failed over instance of the application.
AzureAuth agent authenticates the Azure subscription using the Service Principal credentials. This agent is a persistent resource that monitors the validity of Service Principal credentials.
