How to Use This Document

1. What is CHAI DART™?

CHAI DART™ (Discovery, Assessment & Rationalization Tool) is CloudHedge's AI-powered application portfolio intelligence platform. It provides automated, agentless discovery and deep assessment of enterprise application estates running on Windows and Linux servers — combining live host analysis, network dependency mapping, and automated rationalization into a single intelligence engine.

DART answers three fundamental questions every enterprise must answer before modernizing:

1. What do I have? — A complete, accurate inventory of every application, component, service, and network connection across the estate
2. How complex is it to migrate? — Automated complexity scoring per application using DART's R6Ai® intelligence engine
3. What should I do with each application? — Data-driven 6R rationalization recommendations with AWS cost projections

Key Differentiators

2. How DART Discovery Works

2.1 Discovery Architecture

DART uses an agentless architecture. No software is permanently installed on the source servers. CHAI connects to each host over the network using standard protocols (SSH for Linux, WinRM for Windows) to collect system state information.

2.2 Two-Phase Discovery Process

DART discovery operates in two phases:

Non-Invasive Discovery (Non-X-Ray): For Java application servers (WebLogic, WebSphere, Tomcat, JBoss), DART performs a single-phase discovery. Outgoing connections are determined directly from the application server configuration (DataSource definitions, JMS modules, etc.), making X-Ray unnecessary.

2.3 Projects and Hosts

DART organizes discovery work into Projects. Each project is a logical grouping of hosts:

• Up to 50 hosts per project (Linux and Windows mixed)
• Hosts added by registering credentials (SSH key or password for Linux; WinRM credentials for Windows)
• Hosts can also be added via CSV bulk upload or offline discovery utility
• Projects replaced the legacy "Wave" concept in DART 2.x

3. Windows Host Discovery

DART's Windows discovery is non-intrusive and collects comprehensive system and application state information using WinRM over port 5986.

3.1 What DART Discovers on Windows

IIS Website Discovery (Full Support)

Console & Windows Service Discovery (Beta)

For both Console Applications and Windows Services, DART collects:
- List of file/folder paths of all dependencies
- All DLL dependencies
- Process ID, memory usage, ports, command line, platform (32/64-bit), subsystem

Process Ignore List

Specific processes can be excluded from Windows discovery using the Process Ignore List, configurable per project or globally in Settings.

4. Linux Host Discovery

DART connects to Linux hosts over SSH (port 22) and supports both general process discovery and specialized non-X-Ray discovery for major Java application servers.

4.1 General Linux Process Discovery

For any Linux process, Phase 1 collects:
- CPU, memory, disk, OS, DNS configuration
- All running processes and their ports
- Environment variables, scheduled jobs, network configuration
- Static host entries, external DNS servers

Phase 2 (X-Ray) additionally captures:
- Live inbound and outbound network connections per process
- Hard-coded network dependencies
- File system writes
- External services consumed

4.2 Java Application Server Discovery (Non-X-Ray)

For the four major Java application servers, DART performs a specialized single-phase discovery that extracts full application configuration — eliminating the need for X-Ray probes:

5. Network Intelligence

5.1 Netwatch — Live Network Dependency Capture

Netwatch is DART's network monitoring capability. It captures all inbound and outbound network connections made to/from each host over a configurable monitoring duration — providing ground-truth evidence of actual application communication patterns.

Netwatch is critical for migration wave planning: it reveals hidden dependencies that no static scan or interview can uncover.

How Netwatch Works:
1. Start Netwatch on selected hosts from the project's Discover view
2. Set monitoring duration; optionally clear previous Netwatch data
3. Netwatch runs in the background — status: waiting → in progress → completed
4. Download results as CSV from the project home page (NetWatch Data)
5. DART automatically identifies IPs shared across projects and suggests logical machine groupings

Netwatch CSV Fields: Project_Wave_Name, Host_Alias, Host_IP, Direction, Port, ProcessID, ProcessName, Connected_Host_IP

5.2 Topology Viewer

DART's Topology view visualizes the connections between all discovered hosts and their processes.

Two Topology Views:

Both views support:
- Filtering by host or application
- Customizable layouts
- Double-click on any process, host, or application node for detailed information

6. Rationalization & Assessment

After discovery, DART's Rationalize module applies intelligence to generate actionable migration recommendations.

6.1 The 6R Framework — Host Classification

Every discovered host is classified using the industry-standard 6R migration framework:

Classification values are set per host and feed directly into DART report generation.

6.2 Application Complexity Scoring

DART calculates a containerization complexity score for every discovered process. This is a formula-based, reproducible score — not a subjective expert estimate.

Complexity Score Range:

Complexity is calculated from:

For Linux X-Ray processes:
- 32-bit process or library detected?
- Hard-coded network dependencies?
- Additional packages required?
- Process user (root vs. service account)?
- Special file permissions or special files detected?
- Hard-coded /etc/hosts entries?
- External DNS servers?
- External services consumed?
- File system writes detected?

For Windows IIS websites:
- Windows features required?
- Additional IIS modules required?
- WebAppPool creation required?
- SSL certificates required?
- Group Managed Service Accounts (gMSAs) required?
- File system writes detected?
- External services consumed?

For Java App Servers (Non-X-Ray — WebSphere, WebLogic, Tomcat):
- External Active Directory integration?
- Database integration (DB2, etc.)?
- Message Queue integration?
- SSL certificates required?

6.3 AWS Cost Comparison

DART calculates the estimated monthly cost of hosting all discovered hosts in an AWS region of your choice.

Cost Calculation Components:
- Compute: EC2 instance selection based on discovered CPU/memory/OS specs
- Storage: EBS/storage based on discovered disk usage
- Network: Data transfer costs
- Business Support: AWS support tier
- VDI: Windows Desktop OS virtualization costs

Features:
- Automatic EC2 instance type mapping per AWS region
- Override instance types to model different cost scenarios
- Compare costs across multiple AWS regions
- Pre- and post-Broadcom VMware cost comparison for savings calculation
- 1-year and 3-year NURI (No Upfront Reserved Instance) options

Prerequisites: Project's Target Cloud must be set to AWS with a preferred region configured.

6.4 AWS Graviton Readiness Assessment

Included by default in every DART project. For each discovered host and component, DART shows:
- Graviton Readiness Indicator (compatible / not compatible)
- Graviton-compatible EC2 instance type recommendations
- Readiness by Application Component Types, Technology Types, and Complexity Levels

7. DART Reports & Dashboards

DART generates two types of reports, available as downloadable PDFs.

7.1 DART Report (CXO / Executive)

The DART Report is the project landing page itself — a live, interactive executive summary automatically generated from discovery data.

7.2 Practitioner Report

The Practitioner Report is the detailed technical report for the IT teams responsible for executing the modernization. It is available per Application, per Component, or per Host.

Sections:

Accessing Practitioner Reports:
- From the Rationalize tab → Hosts tab → View Practitioner Report
- From the Rationalize tab → Applications list → View Practitioner Report
- From the project landing page → Applications, Components, or Hosts sections
