There are a lot of powerful open source tools available to create, manage and deploy web maps. However, it still needs a web server and knowledge about webserver/ databases /mapserver software in order to setup a web map. QGIS cloud provides a means to publish web maps from the desktop (QGIS in that case) without having a running database or a webserver. A QGIS plugin helps to upload the data and maps to the cloud portal and the published maps are collected on a webpage.
