Navigating the Horizon interface

How do I navigate the Horizon interface?

The Horizon Interface

The OpenStack web interface is called “Horizon”

Horizon provides visibility and control over all Virtual Machines (VMs) and Volumes within each Project

Supercomputing FAQs

The simple Web UI is backed by an advanced Web Service API

Click around and kick the tires a bit! Horizon only shows you features that you can control

 

Switching Projects

To switch projects, use the omnipresent pull-down

 

Project Quotas

Each project has a set of Limits visible from the Project > Compute > Overview tab

The base subscription* to Stratus includes:

  • 16 vCPUs
  • 50 GB RAM
  • 2 TB of Volume Storage


Exhausted quotas prevent creation of new VMs and Volumes

(*) à la carte pricing is available for larger allocations

 

Instances

The Project > Compute > Instances tab shows active VMs

You can Launch or Delete instances, as well as modify settings for individual instances

All active and manageable VMs are listed in the table

WARNING! A deleted VM is gone for good. Be careful what you delete

 

Volumes

The Project > Compute > Volumes tab shows active data volumes

Volumes store data, and/or active file systems within VMs

You can Create or Delete volumes, as well as modify settings like volume size and attachments

All active and manageable VMs are listed in the table

WARNING! A deleted volume is gone for good

 

Images

The Project > Compute > Images tab shows available images for new VMs

MSI provides a number of “blessed” images. These images come with some pre-configured rules and software for data security

Images can be Launched as VMs or converted into Volumes. Volumes created from images can also be launched as VMs

 

Security Groups

The Project > Compute > Access & Security tab shows security settings (e.g., security groups and key pairs), plus API access information

Security Groups control network traffic to VMs, and work like a firewall

By default Security Groups reject all incoming traffic to VMs. Additional Security Groups can be added with rules to open ports (e.g., ssh to TCP port 22)
