From the end-user perspective, maintenance is minimal, primarily for the infrastructure and application team. The cache must be cleared every time an application is updated, that is something that needs to happen at both the infrastructure and client side. In terms of pricing, I believe the model that some companies are adopting, which is based on user licensing, is problematic because the more users you have, the more you pay. A better approach might be to have a flat site or company-wide pricing structure, reducing the overall costs annually. Previously, with licensing, Microsoft App-V was difficult due to variable costs and specific licensing requirements, and many organizations, including ours, want a central management solution for application virtualization. However, we still have instances where we create master applications and install clients without robust virtualization. On a scale of one to ten, I rate Microsoft App-V a six.
