
Provide a Low Cost Node Option for Partners

Decrease Operations and Maintenance Costs

Simplify Development and Maintenance



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


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 basenode

The ENDS service information can be maintained
automatically

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


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)

2)
Virtual Node Server:
The central node server has been designed and prototyped.
Nodes, services, and tasks have been created and tested.
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.
