The correct answer is: A. SOA
Service-oriented architecture (SOA) is a way of organizing and utilizing software applications as services. It is a way of designing and building software applications that are loosely coupled and can be easily reused and integrated. SOA is based on the idea of breaking down large, monolithic applications into smaller, more manageable services. These services can then be independently developed, deployed, and managed.
SOA is a message-passing architecture. This means that services communicate with each other by exchanging messages. Messages are typically XML documents that contain information about the request being made and the response that is expected.
SOA is a component-based architecture. This means that services are built from reusable components. Components are self-contained pieces of code that can be easily combined to create new services.
SOA provides a number of benefits, including:
- Increased flexibility: SOA makes it easy to add new features and functionality to applications.
- Reduced costs: SOA can help to reduce the costs of development, deployment, and maintenance.
- Improved performance: SOA can improve the performance of applications by making them more scalable and reliable.
- Increased security: SOA can help to improve the security of applications by making them more difficult to attack.
SOA is a complex topic, but it is a powerful tool that can be used to build flexible, scalable, and secure applications.
EBS stands for Enterprise Business System. It is a type of software application that is used to manage the core business processes of an organization. EBS applications typically include modules for accounting, finance, human resources, and customer relationship management.
GEC stands for Global Enterprise Commerce. It is a type of software application that is used to manage the global commerce activities of an organization. GEC applications typically include modules for e-commerce, supply chain management, and order management.
Both EBS and GEC are complex software applications that are used to manage the core business processes of an organization. However, they are not message-passing architectures. They are both monolithic applications that are not easily reused or integrated.
Therefore, the correct answer is: A. SOA
