What are the system requirements for doing Component Load Balancing (CLB) with COM+ in .Net . ours is a migration project we have asp Pages with VB COM Dlls. we are migrating Asp pages to Asp.Net but existing components in VB still be used and newly developed pages will be using .net components. We plan to deploy the COM dlls and Service dotnet dlls in to COM+ in the middle tier cluster and provide load blancing . Microsoft has discontinued issuing fresh licenses for the Application center .( http://technet.microsoft.com/hi-in/library/bb734929.aspx) But I am not clear what is the replacement path ? have any body done that? How to provide load balancing at application server cluster in such scenario ?.
