How does QGIS server work?
The QGIS Server is a FastCGI/CGI (Common Gateway Interface) application written in C++ that works together with a web server (e.g., Apache, Lighttpd). As QGIS desktop and QGIS Server use the same visualization libraries, the maps that are published on the web look the same as in desktop GIS.
How do I use mapping in QGIS?
Go to Layout-> Add a Map. Once the Add map button is active, hold the left mouse and drag a rectangle where you want to insert the map. You will see that the rectangle window will be rendered with the map from the main QGIS canvas. You can see in the far right end the Items box; this shows you the map you just added.
What is a web mapping server?
A Web Map Server is a computer program that produces maps of spatially referenced data dynamically from geographic information. It is a simple interface for web based mapping applications.
How does Web map service work?
A Web Map Service can: Produce a map – as a picture, as a series of graphical elements, or as a packaged set of geographic feature data; Answer basic queries about the content of a map; and. Tell a client what maps it can produce and which of those can be queried further.

How are OGC Web services useful for Web mapping?
The OpenGIS® Web Map Service Interface Standard (WMS) provides a simple HTTP interface for requesting geo-registered map images from one or more distributed geospatial databases. A WMS request defines the geographic layer(s) and area of interest to be processed.

How does QGIS work with a WMS server?
What usually happens is that you have vector layers, which QGIS renders as a map. But using a WMS, those vector layers are on the WMS server, which renders it as a map and sends that map to you as an image. QGIS can display this image, but can’t change its symbology, because all that is handled on the server.
How does a Web Mapping Service ( WMS ) work?
Lesson: Web Mapping Services ¶ A Web Mapping Service (WMS) is a service hosted on a remote server. Similar to a website, you can access it as long as you have a connection to the server. Using QGIS, you can load a WMS directly into your existing map.
