Template options

AWS template options

Items marked with a❗ exclamation mark are required.

The General tab

❗Hostname

Specify a workstation prefix in the Hostname field. Notice the counter textbox: this will be appended onto the workstation prefix. For example, if you entered MyDesktop into the field, the first system’s hostname would be MyDesktop-001

The Platform tab

❗AMI/Image ID

This dropdown/textbox is where the AMI or image ID for the workstation should be selected. The AMI is where we decide which OS and image a workstation should be based on. The Lens Portal allows you to customise the options in this dropdown, see the Image Search page. Select an item from the dropdown.

It is also possible to manually specify an AMI by entering the ID into the textbox.

❗AWS Instance types

This is the size of the instance that will be used for the workstation. You can specify more than one instance type to allow the Lens Portal to automatically adjust the instance type if there is an availability issue. These instance types can be dragged into order to indicate your preferred instance type. Items are sorted into preferred → least preferred.

❗AWS Security Groups

Select one or more AWS security groups that new workstations should be part of.

❗AWS Key Pair

Select the AWS key pair that the workstation should be created with. If you are unsure what to put here, please consult the handover documentation or contact 7fivefive support.

❗AWS Subnets

This subnet (and therefore availability zone) that a workstation will be created. You can specify more than one subnet to allow the Lens Portal to automatically select the best availability zone for the workstation. It’s highly recommended to only create workstations in ‘private’ subnets, and also to have multiple subnets from multiple availability zones selected.

AWS Instance Role

Select the AWS instance role that the workstation should be created with.

❗ AWS EBS type

Select the type of AWS EBS volume that should be used for the workstation's OS/boot volume.

❗ AWS EBS size

Select the size of the workstation's EBS OS/boot volume.

Tags

Tagging workstations is optional, but it can be a very powerful tool when tracking cloud costs. Click the Add tag button to get started.

Advanced

AWS User Data

It’s possible to provide the workstation with custom scripts that it will run upon first boot. This can be useful for installing extra applications or customising the workstation’s configuration. If you need help with this, then please contact 7fivefive support.


VMware template options

Items marked with a❗ exclamation mark are required.

The General tab

❗Hostname

Specify a workstation prefix in the Hostname field. Notice the counter textbox: this will be appended onto the workstation prefix. For example, if you entered MyDesktop into the field, the first system’s hostname would be MyDesktop-001

The Platform tab

Select the VMware vCenter where you would like the workstation to be created.

❗VMware data center

Select the data center where you would like the workstation to be created.

VMware resource pool

❗VMware datastore

Select the data store where the new workstation images will be created. It’s recommended to store the workstation images on shared storage.

❗VMware template

Select the template that the new workstations will be created from. This will dictate the operating system of the workstation.

VMware customisation specification

Select the customisation specification that the workstations should use when being created. These specifications can do things such as bind the workstation to an Active Directory domain or specify a Windows licence key.

❗VMware folders

Select the folder where the workstation will be placed within.
