AWS Application Discovery Service

http://aws.amazon.com/application-discovery
AWS Application Discovery Service automatically collects configuration and usage data from servers, storage and networking equipment to develop a list of applications, how they perform, and how they are interdependent. This information is securely retained in an AWS Application Discovery Service database which you can export as a CSV or XML file into your preferred visualization tool or cloud migration solution to help reduce the complexity and time in planning your cloud migration. Available soon. 

• Provides a set of public APIs and an open data format. This approach allows you to collect data from other discovery solutions in the Application Discovery database, and use this data in a cloud migration solution or within a cloud migration framework provided by System Integration partners.
• Automatically identifies installed applications and running processes on your hosts. The service identifies static host information such as server hostnames, IP addresses, and MAC addresses. Allocation and utilization of key system resources such as CPU, network, memory, and disk are also captured. This information helps you size your AWS resources.
• Discovers network communications and associated processes.  It aggregates this information to derive application and infrastructure level dependencies that exist within your workloads.  This helps account for many dependencies when planning your migration to 
• Captures performance information about applications and processes by measuring host CPU, memory, and disk use, as well as disk and network latency and throughput.  This information lets you establish a performance baseline to use as a comparison after you migrate to AWS.
