General

Q: What is the AWS Application Discovery Service?

AWS Application Discovery Service collects and presents data to enable enterprise customers to understand the configuration, usage, and behavior of servers in their IT environments. Server data is retained in the Application Discovery Service where it can be tagged and grouped into applications to help organize AWS migration planning. Collected data can be exported for analysis in Excel or other cloud migration analysis tools.

Q: How does the AWS Application Discovery Service help enterprises migrate to AWS?

AWS Application Discovery Service helps enterprises obtain a snapshot of the current state of their data center servers by collecting server specification information, hardware configuration, performance data, and details of running processes and network connections. Once the data is collected, you can use it to perform a Total Cost of Ownership (TCO) analysis and then create a cost optimized migration plan based on your unique business requirements.

Q: How does the AWS Application Discovery Service work?

AWS Application Discovery Service supports agent-based and agentless modes of operation. With the agentless discovery, VMware customers collect VM configuration and performance profiles without deploying the AWS Application Discovery Agent on each host, which accelerates data collection. Customers in a non-VMware environment or that need additional information, like network dependencies and information about running processes, may install the Application Discovery Agent on servers and virtual machines (VMs) to collect data.

Q: How can I get started using the AWS Application Discovery Service?

To get started with AWS Application Discovery Service, simply visit the AWS Migration Hub console

Q: Where is AWS Application Discovery Service available?

AWS Application Discovery Service is available worldwide. This means you can perform discovery on resources regardless of their location. The service is hosted in the US West (Oregon) region.

Q: Should I use agentless or agent-based application discovery?

Agentless Application Discovery is recommended for VMware customers because it does not require customers installing an agent on each host, and gathers server information regardless of the VM’s operating systems. It does not collect information on non-VMware environments.

If you run a non-VMware environment, or are looking for process and network connection details, use the AWS Application Discovery Agent. You can run agent-based and agentless Application Discovery simultaneously.

Agent-based Discovery

Q: What data does the AWS Application Discovery Agent capture?

The agent captures system configuration, system performance, running processes, and details of the network connections between systems.

Q: What operating systems does AWS Application Discovery Service provide agents for?

AWS Application Discovery Service provide agents for Microsoft Windows Server 2008 R2, 2012, 2012 R2, RHEL 6 and 7, CentOS 6 and 7, and Ubuntu 14.04. RHEL 6.9, 7.3, and 7.4 and CentOS 6.9, 7.3, and 7.4 versions are not supported. We now have a 2.0 agent available in beta that offers better operating system support. To learn about the new 2.0 beta, see Application Discovery Agent 2.0 (Beta).

Q: How is the data protected while in transit to AWS?

The AWS Application Discovery Agent uses HTTPS/TLS to transmit data to the AWS Application Discovery Service. The AWS Application Discovery Agent can be operated in an offline test mode that writes data to a local file so customers can review collected data before enabling online mode.

Q: How do I install the AWS Application Discovery Agent in my data center?

Please refer to the documentation for details on how to install the AWS Application Discovery Agent.

Q: Will the AWS Application Discovery Service Agent grant AWS remote access to my data center server?

No, the AWS Application Discovery Service Agent deployed on your data center server will not grant AWS remote access. However, the Agent does need to establish an outbound SSL connection to transfer the collected data to AWS.

Q: Can I run agents in my EC2 instances?

Yes. You can install the AWS Discovery Agents on your EC2 instances to perform discovery and report upon performance information, network connections, and running processes, just as for any other server.

Agentless Discovery

Q: What does ‘agentless’ Application Discovery mean?

‘Agentless’ means no software needs to be installed on each host to use Application Discovery. Simply install the AWS Application Discovery Agentless Connector as an OVA on VMware vCenter.

Q: What data does the AWS Application Discovery Agentless Connector capture?

The AWS Application Discovery Agentless Connector is delivered as an Open Virtual Appliance (OVA) package that can be deployed to a VMware host. Once configured with credentials to connect to vCenter, the Discovery Connector collects VM inventory, configuration, and performance history such as CPU, memory, and disk usage and uploads it to Application Discovery Service data store.

Q: What operating systems does the agentless discovery support?

Agentless discovery is OS agnostic. It collects information about VMware virtual machines regardless of the VM operating system.

Q: How is the data protected while in transit to AWS?

The AWS Application Discovery Agentless Connector uses HTTPS/TLS to transmit data to the AWS Application Discovery Service. The AWS Application Agentless Discovery Connector can be operated in an offline test mode that writes data to a local file so customers can review collected data before enabling online mode.

Q: How do I install the Application Discovery Agentless Connector in my data center?

Please refer to the documentation for details on how to install the AWS Agentless Application Discovery Connector.

Q: How can I start the data collection?

Data collection can be enabled or disabled from the AWS console or via the AWS Discovery SDK or AWS Command Line Interface (CLI). Newly installed Connectors have data collection initially disabled when installed.

Q: Will the AWS Application Discovery Agentless Connector grant AWS remote access to my data center servers?

No, the AWS Agentless Connector deployed on your VMware environment will not grant AWS remote access to your data center servers. However, the Agentless Connector requires VMware credentials in order to collect data. These credentials reside locally and are never shared with AWS. The Agentless Connector establishes outbound SSL connection to transfer only the collected data.

Q: Can I run agentless discovery in my EC2 instances?

No. The AWS Agentless Discovery Connector installs on VMware and collects information only from VMware vCenter.

Discovered Data

Q: What kind of information is captured by AWS Application Discovery Service?

AWS Application Discovery Service is designed to capture a variety of data including static configuration such as server hostnames, IP addresses, MAC addresses, CPU allocation, network throughput, memory allocation, disk resource allocations, DNS servers. It also captures resource utilization metrics such as CPU usage and memory usage. In addition, the AWS Application Discovery Agent can help determine server workloads and network relationships by identifying network connections between systems.

Q: Does this service capture any storage metrics?

Yes, disk metrics, such as read and write volume, throughout, allocated/provisioned and utilized capacity, are captured by this service.

Q: How often is the information within AWS Application Discovery Service updated?

Information is gathered only when the AWS Application Discovery Agent or the Agentless Discovery Connector is online.

Using the AWS Application Discovery Service Data

Q: Can I ingest data into the AWS Application Discovery Service from my existing configuration management database (CMDB)?

No, this capability is not supported.

Q: How do I access the data from this service?

Summary data can be viewed in the AWS console. You can export detailed data collected by the AWS Application Discovery Service using the AWS Console or a public API. The service exports data in CSV format.
