%% @doc <fullname>AWS Application Discovery Service</fullname>
%%
%% AWS Application Discovery Service helps you plan application migration
%% projects. It automatically identifies servers, virtual machines (VMs), and
%% network dependencies in your on-premises data centers. For more
%% information, see the <a
%% href="http://aws.amazon.com/application-discovery/faqs/">AWS Application
%% Discovery Service FAQ</a>. Application Discovery Service offers three ways
%% of performing discovery and collecting data about your on-premises
%% servers:
%%
%% <ul> <li> <b>Agentless discovery</b> is recommended for environments that
%% use VMware vCenter Server. This mode doesn't require you to install an
%% agent on each host. It does not work in non-VMware environments.
%%
%% <ul> <li> Agentless discovery gathers server information regardless of the
%% operating systems, which minimizes the time required for initial
%% on-premises infrastructure assessment.
%%
%% </li> <li> Agentless discovery doesn't collect information about network
%% dependencies, only agent-based discovery collects that information.
%%
%% </li> </ul> </li> </ul> <ul> <li> <b>Agent-based discovery</b> collects a
%% richer set of data than agentless discovery by using the AWS Application
%% Discovery Agent, which you install on one or more hosts in your data
%% center.
%%
%% <ul> <li> The agent captures infrastructure and application information,
%% including an inventory of running processes, system performance
%% information, resource utilization, and network dependencies.
%%
%% </li> <li> The information collected by agents is secured at rest and in
%% transit to the Application Discovery Service database in the cloud.
%%
%% </li> </ul> </li> </ul> <ul> <li> <b>AWS Partner Network (APN)
%% solutions</b> integrate with Application Discovery Service, enabling you
%% to import details of your on-premises environment directly into Migration
%% Hub without using the discovery connector or discovery agent.
%%
%% <ul> <li> Third-party application discovery tools can query AWS
%% Application Discovery Service, and they can write to the Application
%% Discovery Service database using the public API.
%%
%% </li> <li> In this way, you can import data into Migration Hub and view
%% it, so that you can associate applications with servers and track
%% migrations.
%%
%% </li> </ul> </li> </ul> <b>Recommendations</b>
%%
%% We recommend that you use agent-based discovery for non-VMware
%% environments, and whenever you want to collect information about network
%% dependencies. You can run agent-based and agentless discovery
%% simultaneously. Use agentless discovery to complete the initial
%% infrastructure assessment quickly, and then install agents on select hosts
%% to collect additional information.
%%
%% <b>Working With This Guide</b>
%%
%% This API reference provides descriptions, syntax, and usage examples for
%% each of the actions and data types for Application Discovery Service. The
%% topic for each action shows the API request parameters and the response.
%% Alternatively, you can use one of the AWS SDKs to access an API that is
%% tailored to the programming language or platform that you're using. For
%% more information, see <a href="http://aws.amazon.com/tools/#SDKs">AWS
%% SDKs</a>.
%%
%% <note> <ul> <li> Remember that you must set your Migration Hub home region
%% before you call any of these APIs.
%%
%% </li> <li> You must make API calls for write actions (create, notify,
%% associate, disassociate, import, or put) while in your home region, or a
%% <code>HomeRegionNotSetException</code> error is returned.
%%
%% </li> <li> API calls for read actions (list, describe, stop, and delete)
%% are permitted outside of your home region.
%%
%% </li> <li> Although it is unlikely, the Migration Hub home region could
%% change. If you call APIs outside the home region, an
%% <code>InvalidInputException</code> is returned.
%%
%% </li> <li> You must call <code>GetHomeRegion</code> to obtain the latest
%% Migration Hub home region.
%%
%% </li> </ul> </note> This guide is intended for use with the <a
%% href="http://docs.aws.amazon.com/application-discovery/latest/userguide/">AWS
%% Application Discovery Service User Guide</a>.
%%
%% <important> All data is handled according to the <a
%% href="http://aws.amazon.com/privacy/">AWS Privacy Policy</a>. You can
%% operate Application Discovery Service offline to inspect collected data
%% before it is shared with the service.

%%
%% </li> <li> Upload your import file to an Amazon S3 bucket, and make a note
