I have a scenario where we have a bunch of Services hosted in BizTalk we want to be able to access it from SharePoint UI (also may be some ASP .Net Applications hosted inside SharePoint.
Can any of other have faced similar scenario's can share with the best practices in terms of performance vs maintainability.
Since we have to cater Security (Authentication (Claims/Kerberos/NTLM to pass through credentials between layers, Authorisation (provided by another WCF not using SharePoint)
Not much logic we have in SharePoint
Our access largely in intranet with 100,000 users with concurrent 10% concurrency.
Any directives or other questions to bring in clarity also welcome.
