SBDIC or SBDC

Share this post:

IBM desktop virtualization is composed of two offerings:

  • SBDIC: Small Business Desktop over IBM Cloud
  • SBDC: Small Business Desktop Cloud

SBDIC

SBDIC (Small Business Desktop over IBM Cloud) provides a virtualization infrastructure based on major components:

  • VMware
  • Citrix (to bring HDX protocol)
  • Desktone

SBDIC can be considered as a black box, providing the infrastructure layer to support desktop virtualization, as shown in the overview diagram:

The DTRAM is a network gateway enabling access to the SBDIC from the Internet.

IBM provides multiple centers throughout the world, to have minimum latency from your point of connection, and can be accessed from the Internet.

Servers, such as Active Directory, and applications servers can be hosted on an IBM site or you need a network link to your data center.

User connection scenario

Connection can happen as follows:

  1. The user connects to the Desktone Portal through a web browser.
  2. The user enters personal credentials.
  3. The user credentials are checked against the Active Directory.
  4. The user is granted to connect to a virtual desktop via HDX protocol.

A single sign-on mechanism is defined. The user does not have to authenticate a second time in order to get access to his or her desktop.

SBDC

The SBDC (Smart Business Desktop Cloud) provides a virtualization infrastructure based on major components:

  • VMware view
  • Xen Destop (hosted on VMware, Xen Server ou HyperV)
  • XenApp
  • Applications delivery using Citrix application streaming or Microsoft APPV

User connection scenario

Connection can happen as follows:

  1. The user connects to the Portal through a web browser.
  2. The user enters personal credentials.
  3. The user credentials are checked against the Active Directory.
  4. The user is granted to connect to a virtual desktop or application publishing through HDX protocol, if using Citrix solution for example.
  5. The user is granted to connect to a virtual desktop through RDP or PCoIP® protocol if using VMware View solution for example.

So, now the question is SBDIC or SBDC?

Remember that architecture choice must be based on functional requirements.

Here are the pros and cons of each:

SBDIC

Pros

Cons

IBM hosted Network link to customer data center
Easy to upgrade the number of desktops Desktop administration and update
Offers a good user experience with HDX®
Good solution for nomad users

SBDC

Pros

Cons

IBM hosted or customer hosted There are no specific disadvantages but read my other blog entries about network, user experience, and desktop type.
Based on main solutions from the market  
You can implement a mixed solution with different products
Desktop virtualization or application publishing
