Horizon Workspace 1.5 Design

Horizon Workspace 1.5 provides end users with a web portal that allows them to access web applications (SaaS), mobile applications, ThinApps, user authored documents, and entitled virtual desktops. The beauty of the solution is that secures your applications and data in your datacenter, while allowing users to access work components from multiple devices from anywhere.

The Applications page displays applications that have been enabled for your use. From this page, you can securely access these applications without reentering your sign in credentials.

If you use a computer running Windows, you can access both Windows and Web applications. VMware ThinApp packages that your organization enabled for you display in the Applications tab. If you are not working on a computer running Windows, Windows and ThinApp packages are not displayed.

You can access your Web applications from any device.

Horizon Files lets you access files you saved to your Horizon folder on any device from anywhere and share these files with others. The files are saved to your Horizon Workspace account automatically and can be accessed on the Web or from your other devices.

The View Desktops page shows the VMware Horizon View desktops that are enabled for your use. When Horizon View is installed on your computer, you can access your View desktops from your Horizon Web client.
You can access your desktops from a Web browser using the VMware Horizon View HTML Access Web client when you do not have the Horizon View client software installed.

The Horizon View Client software offers more features and better performance than viewing your desktop from the browser. For example, with the Horizon View Client software, sound is available when you watch videos. Sound is not available when your desktop is launched from a Web browser.

Horizon Workspace 1.5 is deployed from an multiple VM vApp, it is distributed by VMware as an OVA file. The virtual machines are SUSE Linux Enterprise 11 (64-bit).

The virtual machines that are created are include:
  • gateway-va
  • configurator-va
  • service-va
  • connector-va
  • data-va
  • datava-template
Here is VMware's description of the different components:

During deployment, the Horizon Workspace Setup wizard installs the Horizon Workspace vApp inside the internal network. If you want to provide access to Horizon Workspace for users connecting from outside networks, you must install a load balancer, such as Apache, F5, and so on.

The external load balancer can feed directly into the gateway-va as shown below. This configuration would be used if both the external users and internal users were going through the same gateway-va linux machine.

If you do not use an internal load balancer, you cannot expand the number of gateway-va virtual machines in the future. You might need to add more gateway-va virtual machines to provide redundancy and load balancing. 

Horizon Workspace lets enterprises achieve failover and redundancy by adding multiple virtual machines of the same type in the Horizon Workspace vApp. For instance, you can add a second gateway-va virtual machine and enable the load balancer to redirect requests to both gateways. If one of the gateway-va virtual machines shuts down for any reason, Horizon Workspace will still be available.

Typically, if you have more than 2,000 users, you may need to add an additional gateway-va virtual machine. Additionally, if your deployment exceeds 2,000 users, you must also deploy the public service hostname and IP address with a load balancer.

Working in Horizon Workspace provides secure access to your applications. You can access this information from anywhere and at any time from your laptop, home computers and Android or Apple mobile devices.
