In the past few years, there has been a booming interest in appliances as a strategic delivery vehicle for software products. Appliances offer a shrink wrapped, single purposed blend of software and hardware that can be quickly deployed and configured. This offers customers simplicity; appliances reduce the installation overhead and cost associated with general purpose software stacks. The single purposed nature of the appliance also leads to better performance and simpler management. The hardware and software platform can be tuned to the meet the needs of the appliance application domain, with potential for deep integration (Linux has become very popular as a platform such integration). Management also tends to be simpler for a few reasons: the functions of the appliance are well scoped. Customer expectations are either that they drop down the box, configure it, and never think about it again, or that there will be so many appliances as to necessitate proper management infrastructure.

A strong attraction of the appliance model as a delivery vehicle is customer perception around the pricing of appliances. Bulk software sales are often deeply discounted in order to meet price points and the continuing maturation of the software industry has raised fears of shrinking profit margins. Add in the necessity for lower margin professional services to supplement the knowledge and skill required to extend/build/deploy/etc. and the problem is exacerbated. The appeal of the appliance model is predictability: customers know exactly what they're getting and the price valuation tends to reflect that. In addition, the cost of deployment is greatly reduced as there's no need to customize/re-purpose the generalized software stack to meet specific customer needs.
