What Are Ways To Make Money Online

Test and production, technical environments are required for development. The proper processes can not be enforced unless technical environments are properly setup. The process of Web application development is critical to the success of web-based projects.

But also a major detriment in application failure and budget overrun, deployment and testing is not only a frustrating experience, without streamlined procedures and proper environment settings. And deployed to production on UNIX platforms, applications are developed on NT platforms. Web applications architecture ( http://www.sysoptima.net/architecture/technical_architecture.php ) is typically in 3-tiers.

Development and test environments should be populated with production data periodically. But the configurations should be the same for all three environments, development and test environment may be powered by less powerful computers.

Development Environment

Such as shell scripts and cron jobs, deployment to UNIX environment helps developers to port NT applications to UNIX environment and test UNIX specific tasks, if applications are developed on NT. Role - The development environment is a place where development team develops and tests the applications.

Though installation of new software should be consulted with UNIX admin and DBA, security Concerns - Development team should have full control of and access to the environment.

Test Environment

The deployment of large and complex applications may take many trials. Role - The test environment is a place where QA team (configuration management and software testing http://www.sysoptima.net/software_testing/software_testing_procedures.php ) practices deployment.

Development team members are often involved with deployment to test environment largely because organizations trend to place staff with less technical expertise on QA team, in reality. Development team should not be aware of the existence of the test environment. Security Concerns - QA team is fully responsible for the test environment.

Production Environment

The deployment from test to production should be automated using deployment scripts to avoid the potential human errors and to reduce the deployment cost. Role - The production environment is a place where you serve your customers.

It is the sole responsibility of operation team to maintain the production environment. Security Concerns - Both development team and QA team should not be aware of the existence of production environment.

Depends on management commitment and the technical competency of all teams involved, however, the successful implementation of the procedures. The procedures and technical environment settings described above have been proven to be valuable in eliminating many problems in web-based system implementation.
