You can define and change security group settings in network profiles and in cloud template designs.

You can use security group capabilities in several ways:
  • Existing security group specified in a network profile

    You can add an existing security group to a network profile. When a cloud template design uses that network profile, its machines are grouped together as members of the security group. This method does not require that you add a security group resource to a cloud template design. You can also use a load balancer in this configuration, For related information, see More about load balancer resources in vRealize Automation Cloud cloud templates.

  • Security group component associated to machine resource in a cloud template design

    You can drag and drop a security group resource on to a cloud template design and bind the security group resource to a machine NIC by using constraint tags on the existing security group resource in the cloud template design and on the existing security group in the data-collected resource. You can also make this association by connecting the objects together with a connection line on the cloud template design canvas, similar to how you associate networks to machines on the design canvas.

    When you drag and drop a security group resource onto the cloud template design canvas, it can be of type existing or new. If it’s an existing security group type, you should add a tag constraint value as prompted. If it's a new security group type, you can configure firewall rules.

  • An existing security group allocated with tag constraints and associated with a machine NIC in the cloud template

    For example, you can associate a security group resource with a machine NIC (in a machine resource)in the cloud template design by matching tags between the two resources.

    As an example for NSX-T when tags are specified in the source endpoint, you can use NSX-T tags specified in your NSX-T application. You can then use an NSX-T tag, specified as a constraint on a network resource in a cloud template design, where the network resource is connected to a machine NIC in the cloud template design. NSX-T tags enable you to dynamically group machines by using a pre-defined NSX-T tag that is data-collected from the NSX-T source endpoint. Use a logical port when you create the NSX-T tag in NSX-T.

  • Firewall rules in an on-demand security group resource in a cloud template design

    You can add firewall rules to an on-demand security group in the cloud template design.

    For information about available firewall rules, see More about security group and tag resources in vRealize Automation Cloud cloud templates.
