Web Development Processes and Technical Environments
Introduction
Effective web application development is essential for the success of web-based projects. Achieving this requires properly set up technical environments, which are necessary for development, testing, and production.
Web Application Architecture
Typically, web applications follow a three-tier architecture. Development often takes place on NT platforms, while deployment shifts to UNIX platforms. Without streamlined procedures and correctly configured environments, deployment and testing can become frustrating and lead to application failures and budget overruns.
Environment Configurations
Development and testing environments might use less powerful computers, but their configurations should match the production environment. Regularly updating these environments with production data is crucial.
Development Environment
Role
The development environment is where the team builds and tests applications. If developed on NT, deploying to a UNIX environment is beneficial, allowing developers to adapt applications and test UNIX-specific tasks such as shell scripts and cron jobs.
Security Concerns
Developers should have full control and access, though software installations should involve consultation with UNIX admins and DBAs.
Test Environment
Role
The test environment is used by the QA team to deploy configuration management and software testing practices. Complex applications may require several trials for deployment.
Security Concerns
The QA team manages the test environment independently. Development teams shouldn't be involved with it, although they often are due to a lack of technical expertise within QA teams.
Production Environment
Role
This environment serves the customers. Deployments from test to production should be automated with deployment scripts to minimize human error and reduce costs.
Security Concerns
Development and QA teams should not have access to the production environment, which is maintained solely by the operations team.
Conclusion
Following the specified procedures and setting up appropriate environments have proven effective in avoiding many issues in web-based system implementations. However, success depends on management's commitment and the technical skills of all involved teams.
