Internet Information Services (IIS, formerly Internet Information Server) is an extensible web server created by Microsoft for use with Windows NT family.IIS supports HTTP, HTTPS, FTP, FTPS, SMTP and NNTP. It has been an integral part of the Windows NT family since Windows NT 4.0, though it may be absent from some editions (e.g. Windows XP Home edition), and is not active by default.
The Administration API for IIS was developed as an ASP.Net Core application. This allowed us to take advantage of the Web API conventions that the MVC framework offered. This application has to be accessible at all times to allow users to be able to configure IIS whenever necessary, therefore we needed it to run as a service. Hostable Web Core (HWC) is a technology that allows a consumer to have an in-process version of IIS available to them. When HWC gets loaded in, the process has access to all the capabilities that the full IIS offers. We took advantage of HWC to enable behavior quintessential to the success of the API such as windows authentication, logging, and SSL bindings.
Major Features of IIS
IIS 8.5 has several improvements related to performance in large-scale scenarios, such as those used by commercial hosting providers and Microsoft’s own cloud offerings. It also has several added features related to logging and troubleshooting. The new features are:
- Idle worker-Process page-out: a function to suspend idle site to reduce the memory footprint of idle sites.
- Dynamic Site Activation: a feature that registers listening queues only to sites that have received requests.
- Enhanced Logging: a feature to allow collection of Server variables, request headers and response headers in the IIS logs.
- ETW logging: an ETW provider which allows collecting real-time logs using various Event-tracing tool.
- Automatic Certificate Rebind: a feature that detects when a site certificate has been renewed, and automatically rebinds the site to it.
IIS 8.0 offers new features targeted at performance and easier administration. The new features are:
- Application Initialization: a feature that allows an administrator to configure certain applications to start automatically with server startup. This reduces the wait time experienced by users who access the site for the first time after a server reboot.
- Splash page during application initialization: the administrator can configure a splash page to be displayed to the site visitor during an application initialization.
- ASP.net 4.5 support: With IIS 8.0, ASP.net 4.5 is included by default, and IIS also offers several configuration options for running it side-by-side with ASP.net 3.5.
- Centralized SSL certificate support: a feature that makes managing certificates easier by allowing the administrator to store and access the certificates on a file share.
- Multicore scaling on NUMA hardware: IIS 8.0 provides several configuration options that optimize performance on systems that run NUMA, such as running several worker processes under one application pool, using soft or hard affinity and more.
- WebSocket Protocol Support.
- Server Name Indication (SNI): SNI is an extension to Transport Layer Security, which allows binding of multiple websites with different hostnames to one IP address (similar to how Host Headers are used for non-SSL sites).
- Dynamic IP Address Restrictions: a feature that enables an administrator to dynamically block IPs or IP ranges that hit the server with a large number of requests.
- CPU Throttling: a set of controls that allow the server administrator to control CPU usage by each application pool in order to optimize performance in a multi-tenant environment.
Note: How to find PublicDNS in Azure
Step1 ) RDP Connection: To connect to the deployed instance, Please follow Instructions to Connect to Windows instance on Azure Cloud
Connect to virtual machine using following RDP credentials:
- Hostname: PublicDNS / IP of machine
- Port : 3389
Username: Your chosen username when you created the machine ( For example: Azureuser)
Password : Your Chosen Password when you created the machine ( How to reset the password if you do not remember)
Step 2) Choose Start, expand All Programs, and then expand IIS with Application Server
Step 3) Other Information:
- Windows Machines: RDP Port – 3389
- Http: 80
- Https: 443
