Enterprise customers want software applications delivered as server appliances because they help to reduce IT costs and complexity. Appliances provide better performance, security and manageability. Learn from experts, about factors to consider and things to avoid with the appliance delivery model.

Avoiding the PitfallsIntroduction
For independent software vendors (ISVs) that sell applications to enterprise customers, traditional methods of software deliverycreate operational challenges that can turn into significant business problems. With these methods, which include shippingdisks or having customers download software electronically, delivery is the easy part. The challenges come when customers areconfronted with integrating the application to the latest version the operating system (OS) and service pack on a new server.Then they are faced with the complexity of managing enterprise-class applications on their general purpose servers throughoutthe lifecycles of those applications and devices.
The fundamental difficulty with these models is that on general purpose servers, the ISV's application is just one piece of acomplicated puzzle. That puzzle, which must be assembled correctly in order to run properly, includes supporting applications,management software or middleware, operating systems and hardware platforms. With general purpose servers, these softwarecomponents are exposed to anyone with access to the customer's data center. That leaves too many tempting touch pointsavailable to too many individuals, well-intentioned or otherwise.
The issue is that when something is changed on these servers or the host OS, normal interactions between software elements,or between the software and hardware, can break down and cause the ISV's application to become unavailable. When thathappens, the enterprise customer views it as the ISV's problem. Although the actual technical problem may have nothing todo with their application, the ISV has to figure out the problem and put the puzzle back together. Otherwise, the enterprisecustomer - fairly or unfairly - blames the ISV and becomes dissatisfied with the reliability and manageability of the ISV'sapplication.
That is a situation ISVs cannot afford to let stand. That is why ISVs spend untold amounts of effort, time and money trying toidentify, analyze and address problems anywhere in the software stacks and hardware platforms. This effort causes dramaticincreases in ISVs' support costs, and draws critical human and financial resources away from their core competency of softwareapplication development.
The bottom line is that enterprise applications installed on general-purpose servers open up a host of potential problems that aredifficult, time-consuming and expensive for ISVs to correct. The opportunity costs involved in fixing those problems can quicklyerode an ISV's competitive advantage, slowing development work on their own applications and stalling their growth.
A Smarter Approach - Software Delivered as an Appliance
For many ISVs, a smarter approach to software delivery is the appliance model. By delivering their applications as appliances,software companies can improve their applications' performance and availability by avoiding the problems associated withinstallation on general-purpose servers.
Purpose-built appliances are simple for enterprise customers to install, run and manage. The appliance's locked-down hardwareand inaccessible operating system deter both the hacker and tinkerer, each of whom can wreak havoc on a system. Appliancesprovide the reliable, secure and trouble-free operation that customers expect. They also help the ISV retain some control overthe customer's experience with their application. By reducing operational complexity and enabling higher performance withgreater reliability, appliances drive increased customer satisfaction. Happy customers can be great references and help ISVsmeet their business goals.
This paper discusses the fundamental characteristics of the appliance model and describes its advantages over traditionalsoftware delivery, installation and management methods. It highlights the major benefits the appliance model delivers to ISVsand to enterprise customers. It also discusses the important characteristics and capabilities ISVs should look for in potentialappliance manufacturing partners as companies assess their appliance delivery options.
