Provider-hosted apps are well-suited for SharePoint farms disconnected from the internet. They use digital certificates and signed access tokens to authorize access to SharePoint components like lists and libraries from remote locations. Developer tools like Visual Studio and WebMatrix can be used to create high-trust provider-hosted apps, which require deployment tasks like configuring certificates as trusted authorities in SharePoint. These apps can store and retrieve data from SharePoint and remote sources using languages like C# and APIs.

1. APPS FOR SHAREPOINT
PROVIDER-HOSTED APPS – HIGH TRUST
ESPECIALLY GOOD WHEN THE SHAREPOINT FARM MUST BE DISCONNECTED FROM THE INTERNET
Install high-trust apps to on-premises SharePoint farms, but not to SharePoint Online. High-trust apps can’t be
sold in the Office Store. The SharePoint farm doesn’t have to be connected to the Internet. Can also use the
cross-domain library as part of a dual authorization system.
AUTHORIZATION TO SHAREPOINT
DIGITAL CERTIFICATES
SharePoint uses trusted
digital certificates to sign
access tokens.
REMOTE COMPONENTS
The app includes a signed
access token in requests to
create, read, update, or
delete SharePoint data or
objects.
TOKEN FROM
CERTIFICATE
SHAREPOINT
SharePoint components - like lists,
document libraries and
workflows. Accepts access tokens
signed by a trusted digital
certificate.
