The drawback in using GoogleMaps is two-folded: On one hand you will use proprietary things and everything is hosted using google servers. Another disadvantage is this sticky basemap. You cannot use other layers as basemap.

Served data is the major need for a nice web-map. If you want to serve your own shapefiles / geodata without using services like ArcGIS online you may want to have a look on GeoServer. Geoserver gives you the possibility to deploy your own WMS and show your web-map using OpenLayers as well. Due to its user concept and universality I think it is the most advanced alternative to the cost intensive ArcGIS Server environment:
