Virtel Web Suite | VWS | Overview


Serve host applications as web pages or web services over TCP/IP connections


VIRTEL is a comprehensive web-enablement technology that serves legacy host applications such as CICS®, IMS, Natural or TSO as web pages or web services over TCP/IP connections. Web-enabling extends the relevance and investment of critical legacy systems. It is more cost-effective and provides earlier ROI than redeveloping, replacing, or re-hosting.


 
Virtel Web Access

Virtel Web Access

Extends host applications to thin-client web browsers over secure IP connections while retaining their familiar 3270 screen user interface:

  • Nothing to install or support outside the host
  • Instant deployment: simply point the clients' web browsers to the predefined URL
  • Works with any browser or platform including mobile devices (smartphones and tablets), Apple products, and new versions of Windows
  • Recommended for BYOD, VDI and DR initiatives, and to replace client-based 3270 TE

 
Virtel Web Modernization

Virtel Web Modernization

Serves host transactions as user-friendly web pages (GUIs) that provide a genuine web experience:

  • Assisted data entry: checkboxes, dropdown lists, graphical calendars, auto-suggest, auto-complete, and more
  • New Ajax-based application features: suggest, auto-complete, PDF generation, email, and more
  • New layout and workflow: screen consolidation, tab navigation, collapsible sections, and more
  • Can serve different presentations to different users (3270 TE, WUI/GUI, mobile UI) concurrently

 
Virtel Web Integration

Virtel Web Integration

Creates interactive bidirectional connections that integrate host and server applications, e.g. RESTful XML or JSON over HTTP, SOAP and MQ message services that consume 3270 transactions.

Key Features

  • Serves 3270 transactions as web pages or web services
  • Nothing to install or support outside the host
  • Instant deployment: simply point the client's web browsers to a predefined URL
  • Works with any browser or platform including mobile devices (smartphones, tablets), Apple products, and new versions of Windows
  • Concurrently serves different presentations to different users (3270 TE, WUI/GUI, mobile UI)
  • Supports any web service protocol and format: RESTful, XML, JSON, SOAP, MQ Series, etc.
  • Low impact and low risk: no application or transaction server change
  • High performance and small host footprint result in highly scalable solutions
  • Simple host-centric configuration and support result in low TCO and early ROI

Design Principles

The architecture of VIRTEL relies upon the following design principles:

  • Shorter instruction paths result in superior performance, efficiency, and scalability
  • Fewer components or layers result in simpler and stronger connections
  • Strict use of open standards results in increased solutions longevity

Architecture

Virtel Web Suite Architecture

Virtel is an agile middleware to connect host applications to the Web. It interfaces with:

  • Host applications via their 3270 screens or COMMAREA
  • The Web via HTTP/S, SMTP, or custom IP connections

Virtel converts host application data into rich web pages and standardized web services.
