web application in SharePoint

A web application in SharePoint is any individual IIS website created to access and use SharePoint Server technologies and services. Each web application has its own domain name and use zones to contain and apply different access and policy rules for different sets of users. This brings benefits while managing large numbers of SharePoint users who need to access the same site but view and interact with different levels of content.

Planning for web applications should center on the need to either share or isolate specific web content. For instance, different content can be presented for authenticated vs anonymous users or information can be contained so that internal employees, customers, and partners all access different types of web content. Policies for a web application let you set security and permissions at the level of the web application. You can set policies in Active Directory Domain Services users and user groups but not in SharePoint groups. Best practice suggests using these features to manage large numbers of users in user groups.

Once you create web application you will find one IIS website and one application pool under IIS Manager, as mentioned earlier web application is an iis website.

zones in sharepoint

default zone in SharePoint

Zones are different logical paths expressed as URLs that allow access to the same web application. The default zones in sharepoint is 5. A web application can support up to five Default Zones. The available zone names are Default, Extranet, Intranet, Internet, and Custom.

One particular zone name can be used per web application. Zones using the same name across different web applications typically are available for the same user pool to control access for that group. For instance, your internal employees can use the Intranet zone to access all of the SharePoint sites configured to use that zone, giving that group the same sort of access to all relevant web applications. Each zone is expressed as a separate website in IIS. Zones isolate users based on authentication type, network zone, and policy. All zones have own Port number and Protocol http/https. Different authentication methods can be applied to login different zones like Forms authentication in Intranet and default Windows authentication. we can configure Blob and Distributed cache differently for different zones. When planning for zone deployment, particular attention must be paid to the Default zone, since access to this zone may be gained by anyone who is able to use a link to this zone, such as a URL sent via an automated administrative email. The Default one or any zone used for an outward-facing site must possess a high level of security.
