// AWS Application Discovery Service helps you plan application migration projects
// by automatically identifying servers, virtual machines (VMs), software, and
// software dependencies running in your on-premises data centers. Application
// Discovery Service also collects application performance data, which can help
// you assess the outcome of your migration. The data collected by Application
// Discovery Service is securely retained in an Amazon-hosted and managed database
// in the cloud. You can export the data as a CSV or XML file into your preferred
// visualization tool or cloud-migration solution to plan your migration. For
// more information, see the Application Discovery Service FAQ (http://aws.amazon.com/application-discovery/faqs/).
//
// Application Discovery Service offers two modes of operation.
//
//    * Agentless discovery mode is recommended for environments that use VMware
//    vCenter Server. This mode doesn't require you to install an agent on each
//    host. Agentless discovery gathers server information regardless of the
//    operating systems, which minimizes the time required for initial on-premises
//    infrastructure assessment. Agentless discovery doesn't collect information
//    about software and software dependencies. It also doesn't work in non-VMware
//    environments. We recommend that you use agent-based discovery for non-VMware
//    environments and if you want to collect information about software and
//    software dependencies. You can also run agent-based and agentless discovery
//    simultaneously. Use agentless discovery to quickly complete the initial
//    infrastructure assessment and then install agents on select hosts to gather
//    information about software and software dependencies.
//
//    * Agent-based discovery mode collects a richer set of data than agentless
//    discovery by using Amazon software, the AWS Application Discovery Agent,
//    which you install on one or more hosts in your data center. The agent
//    captures infrastructure and application information, including an inventory
//    of installed software applications, system and process performance, resource
//    utilization, and network dependencies between workloads. The information
//    collected by agents is secured at rest and in transit to the Application
//    Discovery Service database in the cloud.
//
// Application Discovery Service integrates with application discovery solutions
// from AWS Partner Network (APN) partners. Third-party application discovery
// tools can query the Application Discovery Service and write to the Application
// Discovery Service database using a public API. You can then import the data
// into either a visualization tool or cloud-migration solution.
//
// Application Discovery Service doesn't gather sensitive information. All data
// is handled according to the AWS Privacy Policy (http://aws.amazon.com/privacy/).
// You can operate Application Discovery Service using offline mode to inspect
// collected data before it is shared with the service.
//
// Your AWS account must be granted access to Application Discovery Service,
// a process called whitelisting. This is true for AWS partners and customers
// alike. To request access, sign up for the AWS Application Discovery Service
// here (http://aws.amazon.com/application-discovery/preview/). We will send
// you information about how to get started.
//
// This API reference provides descriptions, syntax, and usage examples for
// each of the actions and data types for the 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 AWS SDKs (http://aws.amazon.com/tools/#SDKs).
