Web browsers enable users to view HTML documents HTML is what is contained in a web page
HTTP is how the mechanics of web pages are requested and delivered; HTML is what is delivered.
Web Mapâ contains one or more ArcGIS Server map services that are referenced from ArcGIS Online Web Map Serviceâ a set of interface specifications that provide uniform access by web browser clients to map servers over the WWW. WMS is a standard defined by the Open Geospatial Consortium. Web Serviceâ software apps or data accessible over the WWW From the Help: What is the difference between a web map and a web application within the context of the website? A web map is an interactive display of geographic information, for example, satellite imagery of streets, houses, and open space within Los Angeles County. You can view it in a browser, mobile device, or desktop application and use tools to change the extent, find places, and see detailed data about a specific location. In addition, you can build your own map by defining an area of interest, choosing a basemap, and adding data layers. You can save maps and share them with everybody or with specific groups you belong to. A web application is a website that combines maps, data, and tools for a targeted use such as a polling stations application. It might be as simple as a map embedded in a blog or as complex as GPS navigation app or operational dashboard. Applications can be based on standard templates, which are configured using web maps and other properties and developed with ArcGIS APIs. In general, applications are constructed from information in web maps, supplemented with additional application-specific configuration and customization. Applications can be hosted as a part of your content in the system or they can be managed independently and registered with the system.
Itâs accessing mapping whenever you want, wherever you are, on any device that runs web browser software. Even if Internet connectivity is unavailable, there are mechanisms for saving and using locally-stored data.
Devices can be as cheap as smartphones or iPad, Android tablets (like $200 Nexus 7) To access the data, they need to click through a Proof of Delivery form that insures they got it.
Closely associated with the whole web services paradigm is the notion of the Cloud. Donât think of it as just another remote server that has to be purchased, provisioned and attended to by internal IT staff. Itâs a utility that you plug into whenever you need it, at whatever scale you require. You donât have to wait for corporate to approve it, then acquire and install it. You donât keep paying for it till itâs way past its prime. You can scale up and down as needed.
No need to wait for corporate authorization and delay for hardware purchases
The Share settings in the viewer control how you can publish the map. If you just want to keep it to yourself, no sharing is necessary. If you want to share the map with your group, you have to select the group. Sharing with the group allows you also to publish the map as a web application.
A published web application is based on a web map authored with the ArcGIS.com map viewer.
While somewhat limited in functionality when compared to your own ArcGIS for Server services, ArcGIS Online also offers simple hosted tiled and feature services. ArcGIS Online Hosted Services remove many of the hassles of having to maintain and scale your own services and they are provided at an extra cost that follows a âpay for what you useâ pricing model. You may want to consider complementing your ArcGIS for Server deployment with ArcGIS Online Hosted Services for simple web mapping needs, particularly for public facing web applications.  Current capabilities of AGOL: Tiled map services - fast display of your data - tiles build in ArcGIS Online - support for queries with an associated feature service - no dynamic mapping Feature services - supports editing - ability to track edits - supports owner based editing (only creator of a feature can edit it) - Ability to download data via shapefile for local synchronization
Amazon Elastic Block Storage  (EBS) provides raw block devices , that can be attached to Amazon EC2  instances. These block devices can then be used like any raw block device. In a typical use case, this would include formatting the device with a filesystem  and mounting  said filesystem. In addition EBS supports a number of advanced storage features, including snapshotting and cloning. Currently EBS volumes can be up to 1TB in size. EBS volumes are built on replicated back end storage, so that the failure of a single component will not cause data loss.
