%% @doc Amazon Web Services Application Discovery Service
%%
%% Amazon Web Services 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 Amazon Web Services Application Discovery Service FAQ. Application
%% Discovery Service offers three ways of performing discovery and collecting
%% data about your on-premises servers:
%%
%% <ul> <li> Agentless discovery 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> Agent-based discovery collects a richer
%% set of data than agentless discovery by using the Amazon Web Services
%% 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> Amazon Web Services Partner Network
%% (APN) solutions 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 Amazon Web
%% Services 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> Recommendations
%%
%% 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.
%%
%% Working With This Guide
%%
%% 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 Amazon Web Services SDKs to access
%% an API that is tailored to the programming language or platform that
%% you're using. For more information, see Amazon Web Services SDKs.
%%
%% Remember that you must set your Migration Hub home region before you call
%% any of these APIs.
%%
%% You must make API calls for write actions (create, notify, associate,
%% disassociate, import, or put) while in your home region, or a
%% `HomeRegionNotSetException' error is returned.
%%
%% API calls for read actions (list, describe, stop, and delete) are
%% permitted outside of your home region.
%%
%% Although it is unlikely, the Migration Hub home region could change. If
%% you call APIs outside the home region, an `InvalidInputException' is
%% returned.
%%
%% You must call `GetHomeRegion' to obtain the latest Migration Hub home
%% region.
%%
%% This guide is intended for use with the Amazon Web Services Application
%% Discovery Service User Guide.
%%
%% All data is handled according to the Amazon Web Services Privacy Policy.
%% You can operate Application Discovery Service offline to inspect collected
%% data before it is shared with the service.
