Can I create a ArcGIS web application without ArcGIS server, using only ArcGIS online services?
Yes.
The only thing that ArcGIS server would be supplying to a web application is map services or geoprocessing services. These can be hosted on ArcGIS Online (AGOL) instead. For examples, look at the ArcGIS JavaScript API samples, almost all of which use AGOL map services in their implementation.
The application itself, if built in JavaScript, can be hosted on any web server and does not require an ArcGIS Server install.
Absolutely! You can easily upload your data to ArcGIS Online and create Hosted Feature Services, then add those to a web map, and then create an app based on that web map (no coding is even required unless you need something customized for your workflow). Good luck!
Yes, although currently MapServer service is not listed under supported types of hosted layers:
https://doc.arcgis.com/en/arcgis-online/share-maps/hosted-web-layers.htm
MapServer allows for delivering just map images for an individual service to the client and provides the feature data by request. Hosting it doesn't seem to be a option in ArcGIS Online in current implementation.

I am a newbie. I'm researching about QGIS to create a webgis. I don't know that have QGIS supported about returning data as a web service?
QGIS Server is an implementation of various OGC web service standards that you can use. However, I think you're better off considering PostGIS and GeoServer.
BIM 360 Team has a nice built-in commenting tool that tracks issues. Is it possible if we can use the exact same feature inside Forge Viewer API? (my question may sound convoluted because I'm not a software engineer..) For any one who doesn't know the feature, please see below article. Any help is much appreciated.

Thanks!
Yes, it is definitely possible. The Autodesk development teams make use of Forge web services to implement A360 features. You have access to the same web services. You may even be able to peruse and analyse their code in the JavaScript debugger to see how they implement the client side user interface on top of the server side web service. In this case, the web service being used is the Issues API. More on that topic here:

I am looking to expose an existing app as web service for use on the Blackberry. So I have some questions around the blackbery and its use of web services.
I am wonderings is it possible to use Restful web services (using JSON as the payload) on the blackbery or is SOAP the only web services the balckbery can do?
In recent times I have used the Jersey framework for web services in normal web apps and I think this would suit my current requirements,just need to know if this is possible on the blackberry. Effectively the blackbery would only need to send/recive/procees HTTP calls and JSON so I would imagine this would be possible?
Also I may have to use the enterprise blackberry server, how do I route requests to/from the app (and the enterprise server) to the back end existing app. Is this all seamless with some config settings on the enterprise server or does the the blackberry application need to handle this in a certain way?
You can definitely use a RESTful service and JSON on the BlackBerry. Depending on the version you are targeting you may have to download a JSON library. There is also a good reference guide at http://java.sun.com/developer/technicalArticles/javame/json-me/ you can look through.
The Enterprise server shouldn't affect your ability to use this, as you're essentially making the same calls a browser would, and it will know how to route that traffic.
I'm trying to display on the web (read as create a GIS Web app) topo data layers stored in a POSTGIS/POSTGRES spatial database using mapserver. My problem is, although i happened to come across different gis frameworks that I could use, my lack of experience on using mapserver in the first place makes me indecisive of which framework to use. So what is the easiest framework out there to use? I'm using a MS4W pre-packaged mapserver binaries, and i've installed almost all of the additional packages (frameworks) from their site.
Thanks for the help!:) I
Mapfish (I think python and C based and ideal with mapserver)
GeoServer (java based)
Featureserver (RESTful, light and effective)

I've used Geoserver and Feature server on multiple occasions, and never got deep into mapserver. I know that Mapserver has a big community and they love helping out, check them out on IRC and their mailing list.
We have developed an interface called OWGIS for displaying GIS data.
Website: http://www.owgis.org
Description:
The OWGIS (Open WebGIS) is an OpenSource Java Servlets web application that creates WebGIS sites by automatically writing HTML and JavaScript code. The WebGIS sites are configured by XML files that define which layers will be displayed on the maps as well as the texts to be used on the interface. OWGIS's most notable features include animations, veritcal profiles and vertical transects, various color palettes, dynamic maps, downloadable data, and multilingual interfaces. All these features are created automatically without any additional web programming.
Since you already got MS4W installed. The easiest way to publish a map service from Postgres is from MapServer which is component of the ms4w.
To start publish wms from MapServer,
1) Read thru the documentation of Mapfile which is the service definition file of how the WMS configured.
2) Read the ogr postgis connection documentation. You would be able to write the database connection follow the instruction pretty easily.
3) Once you got the valid Mapfile with correct postgis connection string info, you are able to publish the WMS for your topos.
MapServer is very powerful and easy to use. The file based service provide a lot of flexibility which is critical when you need publish something dynamically.
GeoServer is very popular too and has a gui which is extremely easy to use, by several click and your services are ready to go.
Other solutions are also available as well. But consider the community user base and tech support. I would recommend using MapServer or Geoserver for your case. We had our Mapserver holding USGS topo services as well, which is very stable,flexible and salable so just some FYI.
Hope it is helpful.
(I hope this is a valid question)
As I stated in my title, I'm looking for a fairly easy to moderately easy idea for some sort of online raster analysis map. I'm familiar with ESRI and their really awesome API, as I'm hoping to tackle something on that front. I'm also open to using the mapstraction lib.
Does anyone have any ideas for me?
Thanks!!
I'm not sure you mean image rasters or data rasters. This uses open source packages: MapServer and an AJAX client MsCross. It generates data rasters on the server and displays them in the browser. The rasters are contour plots for a plume of contamination in groundwater.
If you are already familiar with ESRI, then you should look at the ESRI Flex API ESRI Javascript API. You can use both of them to fire up Server side Geoprocessing services.
There are so many ways to skin the cat...
You may want to check the Publishing a GeoProcessing Service section of ESRI help
The basic idea is this... you use ArcMap/ArcCatalog to author a Geoprocessing Model (I am assuming you are familiar with this), which you later expose in an ArcGIS Server as a Geoprocessing Service. Publishing a model as a service is pretty easy provided you already have an ArcGIS Server configured - see the links I provided you above.
Then you can either use the free ArcGIS Explorer application to consume that GeoProcessing Service or write a webapp using Flex, or Javascript or DotNet or even python to consume that webservice.
And yeah, don't consume the webservice synchronously - stick with async.
You do unfortunately not write, what exactly you need. Do you want to display maps on a web page or in a application?
In the latter case i would recommend using http://www.openstreetmap.org/ it seems to be a little tricky in the beginning, buts data base gets better and better. A number of renderes exist, which you can integrate into your application.
