Why a Virtual Node

A central node server that hosts any number of partner nodes: state, tribe, region, agency, etc..

Each partner node is simply configured on the central or cloud server from a web application

Each partner node functions like a conventional node only it is much simpler and cheaper to set up and maintain

What is the Virtual Node

Low Cost: Costs should be significantly lower compared with a traditional node

Highly Agile: A new partner node can be created with a simple configuration form

Enhanced Manageability: Nodes are centrally managed, secured and serviced

Common Architecture: New features will be shared by all nodes

Virtual nodes can ‘inherit’ services from the base-node The ENDS service information can be maintained

automatically

Virtual Node Advantages

Nodes are moved to the cloud, not the databases.

Nodes connect to databases through a secure backend bridge or VPN.

A node admin controls each node, and how it accesses the their databases.

• The ENVN is a node with its own web services description language :

• Node Management: CreateNode, UpdateNode, DeleteNode and GetNodeList. • New nodes are created by the helpdesk

• Service Management: CreateService, UpdateService, DeleteService and GetServiceList – • Services could be automatically published to ENDS

• Dataflow Management: CreateDataflow, UpdateDataflow, DeleteDataflow and GetDataflowList.

• Task Management: CreateTask, UpdateTask, DeleteTask and GetTaskList • Used to schedule tasks

Based on a partner’s internal security requirements, they might choose:

Virtual Private Network Connection

Backend Relay with Internet Service Bus (ISB)

Direct Backend Database Bridge

Backend Relay with AppFabric

Secure Database Connection Options

VN Mapping Process

Two Key Steps 1. Data Mapping: Create a one to one

relationships between data columns and XML elements (Map Force, SQL Query Builder, Oracle Query Designer)

2. Structure Construction: Put the XML element into hierarchy at the correct position using XLST (XSLT style-sheet is simplified and generated – not coded)

XML Mapping & Transformation

1) Virtual Node Server:The central node server has been designed and prototyped. Nodes, services, and tasks have been created and tested.

2) Secure Database Connections:Secure processes for connecting to State databases have been designed and developed. We are testing remote database connections from the virtual node to our EPA Clydesdale database server. A sample database has been integrated simplify the creation of test services by partner administrators.

3) Admin User Interface: A graphical user interface is under design. Wireframes have been generated. Features and functions are being designed.
