Virtel Web Integration | VWI


Create interactive bidirectional connections that integrate host and web applications


Virtel Web Integration
 

When it comes to integrating mainframe and web applications through web services, you won't find a better blend of simplicity, flexibility, performance, low resource consumption, scalability, and low TCO than Virtel.

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

Product Highlights

Virtel quickly and simply integrates host applications such as CICS® and IMS with server-based technologies through interactive bidirectional connections, typically SOAP, RESTful and MQ services that consume 3270 transactions. Virtel can expose the host transactions either through their legacy screen UI or through a COMMAREA if/when the screen UI is removed:

  • No code change when reusing screen UI
  • Allows retaining the business logic while eliminating the screen UI
  • Supports REST, HTML, XML, SOAP, MQ, PHP, JSON and more
  • Fast and simple implementation
  • Superior performance and scalability in a small host footprint
  • Low Total Cost of Ownership (TCO)

Virtel extends the relevance of - and investment in - legacy host applications.

Typical Applications

Typical Virtel Web Integration applications include:

  • Incoming web services: expose host assets to a WebSphere, WebLogic or other web portal
  • Outgoing web services: enable CICS and IMS applications to issue outgoing SOAP web service calls with minimal impact on host application code
  • Batch/Web integration: support interactive bidirectional XML connections between host applications and web
  • PHP integration: integrate CICS and IMS applications with PHP servers
  • SNA/IP migration: replace unsupported SNA/3745 connections with TCP/IP
  • Financial EDI: automate format and protocol conversion (e.g. CBCOM, CB2A, AMEX, EBICS, OSI, non-OSI, EMV, and SEPA) between COBOL host applications (e.g. CICS, IMS) and remote financial institutions
  • Large data transfers: support exchange of large (over 32KB) data blocks between host and web applications
  • Application interoperability: enable cooperative processing between host and web applications through interactive bidirectional data exchanges

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.
