IBM i Apache Server - The IBM i Integrated Web Server

About IBM i Apache Server - The IBM i Integrated Web Server

Train your IBM i System to listen to incoming webservices from the Internet. Using IBM's integrated Webserver (previously known as Apache) you can easily and quickly expose specific business functions to the internet - while taking care to fully secure all access through the business logic already built into your application programs.

Providing web services for external calls to your IBM i system can offer several significant benefits.

  • Integration with Modern Applications
    Web services allow your IBM i system to communicate with modern applications, platforms, and services, regardless of the technology stack they use. This enables seamless integration with web, mobile, and cloud applications.
  • Access to Business Logic and Data
    By providing web services, you can expose critical business logic and data stored on your IBM i system to external applications, allowing them to leverage your existing resources without needing to replicate data or functionality.
  • Support for Multiple Protocols
    Web services can be implemented using REST (Representational State Transfer) or SOAP (Simple Object Access Protocol), providing flexibility in how external systems interact with your IBM i applications.
  • Enhanced Collaboration
    Web services facilitate collaboration with business partners, suppliers, and customers by allowing them to access your services and data securely and efficiently.
  • Scalability and Flexibility
    Web services can be designed to handle varying loads, making it easier to scale your applications as demand increases. This is particularly useful for businesses experiencing growth or seasonal fluctuations.
  • Improved User Experience
    By integrating web services, you can create modern user interfaces for your applications, improving the overall user experience and making it easier for users to access and interact with your systems.
  • Cost Efficiency
    By exposing existing functionality through web services, you can reduce the need for duplicate development efforts, saving time and resources.
  • Mobile and Cloud Readiness
    Support for Mobile Apps: Web services enable the development of mobile applications that can interact with your IBM i system, allowing users to access services and data on the go.
    Cloud Integration: They also facilitate integration with cloud-based services and applications, enabling hybrid solutions that leverage both on-premises and cloud resources.
  • Security and Control
    Web services can be secured using various authentication and authorization mechanisms, allowing you to control who can access your data and services.
  • Future-Proofing
    By adopting web services, you position your IBM i system for future growth and modernization, ensuring that it can adapt to changing business needs and technological advancements.

Integrating web services for external calls into your IBM i system can dramatically expand its functionality, boosting accessibility, versatility, and seamless integration with the wider world of technology. Such a strategy not only streamlines operations but also paves the way for groundbreaking collaboration and innovation.
