Enterprises today function in multi-location, multi-user environments that encompass multiple technologies and platforms. While being enormously beneficial to the enterprises in their quest to ensure higher quality at affordable prices and lower risks, this also translates into a newer set of challenges.

• This dynamic environment consists of disparate systems. Hence, one size just doesn't fit all!
• Given this dynamism and consequent customizations ,maintainability of applications in such an environment is often a nightmare!
• Software, especially Operating Systems, are constantly getting better and better, while the hardware vendors are catching up to keep pace with the software and ensure better compatibility.
• Faced by a market of financial fragility and increasing client demands, IT departments desire to use newer and better systems, while keeping the procurement and operational cost at a minimum.
• Many software product and service providers such as Microsoft stop supporting lower versions after a pre-scheduled deadline, which leaves users of these products who haven't migrated to newer versions, in the lurch!
