what is the solution to support windows application services on the web?

[saeedpepper]

In our company we have an enterprise windows application, Now we have decided to publish some of the business services on the web and let web clients to work with our enterprise application. How we can do it ? with considerations: - The web clients have low speed Internet. - The Web application is going to support some of the business use cases. - We need high security for using the services. - We use C#.net , and Sql server and asp.net

We are thinking of two solutions :



Solution 1: picture for first model

Solution 2 picture for second model

which model is better ? do you have another solution?

Thanks for your attention...
