AWS Application Discovery Service helps plan migration to the AWS cloud by collecting usage and configuration data about the on-premises servers.
helps enterprises obtain a snapshot of the current state of their data center servers by collecting server specification information, hardware configuration, performance data, details of running processes, and network connections
which simplifies migration tracking as it aggregates migration status information into a single console.
can help view the discovered servers, group them into applications, and then track the migration status of each application.
discovered data for all the regions is stored in the AWS Migration Hub home Region.
The data can be exported for analysis in Microsoft Excel or AWS analysis tools such as Amazon Athena and Amazon QuickSight.
supports both agent and agentless-based on-premises tooling, in addition to file-based import for performing discovery and collecting data about the on-premises servers.
Application Discovery Service Modes
is an on-premises application that collects information through agentless methods.
can be performed by deploying the Agentless Collector (OVA file) through the VMware vCenter.
After Agentless Collector is configured,
it identifies VMs and hosts associated with vCenter.
collects the following static configuration data: Server hostnames, IP addresses, MAC addresses, and disk resource allocations.
Additionally, it collects the utilization data for each VM and computes average and peak utilization for metrics such as CPU, RAM, and Disk I/O.
can be performed by deploying the Application Discovery Agent on each of the VMs and physical servers.
supports most Windows and Linux operating systems.
can be deployed on physical on-premises servers, EC2 instances, and virtual machines.
collects static configuration data, detailed time-series system-performance information, inbound and outbound network connections, and processes that are running.
pings the Discovery Service at 15-minute intervals for configuration information.
transmits data securely to the Discovery Service using TLS encryption.
AWS Certification Exam Practice Questions
Questions are collected from Internet and the answers are marked as per my knowledge and understanding (which might differ with yours).
AWS services are updated everyday and both the answers and questions might be outdated soon, so research accordingly.
AWS exam questions are not updated to keep up the pace with AWS updates, so even if the underlying feature has changed the question might not be updated

A company is migrating its on-premises systems to AWS. The user environment consists of the following systems:
• Windows and Linux virtual machines running on VMware.
• Physical servers running Red Hat Enterprise Linux.
The company wants to be able to perform the following steps before migrating to AWS:
• Identify dependencies between on-premises systems.
• Group systems together into applications to build migration plans.
How can these requirements be met?
Install the AWS Systems Manager Discovery Agent on each of the on-premises systems.
Install the AWS Application Discovery Service Discovery Agent on each of the on-premises systems.
Install the AWS Application Discovery Service Discovery Connector on each of the on-premises systems and in VMware vCenter.
Install the AWS Application Discovery Service Discovery Agent on the physical on-premises servers. Install the AWS Application Discovery Service Discovery Connector in VMware vCenter.
