Middleware application servers: Loosening the constraints of proprietary
lock-in
,----[ Quote ]
| The bustling marketplace for enterprise-grade Windows-to-Linux
| migration tools proves that many companies are looking into open
| source software products. Although no one-size-fits-all solution works
| for all Windows to Linux migrations, many software and service
| solutions providers stand ready to assist in such efforts, providing a
| range of services from planning through integration and deployment
| to on-going training and support.

|
| As Windows-centric enterprises migrate to Linux, one typical sticking
| point pops up in terms of software applications for mission-critical
| business functions or services. On corporate desktops, emulation
| techniques such as VMware or Win4Lin permit peaceful coexistence
| between Linux and Windows-only applications. On corporate servers,
| virtualization consolidates software and hardware resources, meaning
| disparate Windows-based services may be unified on large-scale,
| heavy-duty Linux server systems or clusters. Middleware application
| servers come into play when proprietary database and application servers
| or services like Active Directory foster resistance to migrations
| because users do not want to lose the functionality.
|
| Middleware creates an abstraction layer between the operating system
| and application components in distributed network environments.
| Ostensibly, middleware acts as transparent glue betweenh
| eterogeneous platforms to facilitate network-based transactions.
