Introduces the Service-Oriented Architecture (SOA) pattern to enhance modular service interaction.

This PR addresses the need to implement Service-Oriented Architecture (SOA) to improve the interaction between modular services within the application. The SOA pattern facilitates loose coupling, service abstraction, reusability, interoperability, scalability, statelessness, discoverability, and security, enhancing the overall architecture of the system.

The main points considered when implementing SOA are:

• Loose Coupling: Services should operate independently without knowledge of other services.
• Service Abstraction: Services hide complexity behind a clear interface.
• Service Reusability: Services are designed for reuse across different parts of the application.
• Interoperability: Services operate with other services using standard protocols.
• Scalability: Services can be scaled independently to handle increasing loads.
• Statelessness: Services handle each request independently, increasing reliability.
• Discoverability: Services can be easily discovered through standard mechanisms.
• Security: Robust security measures are implemented to secure communication and data access.

Implementing SOA involves setting up a service registry, defining service interfaces, ensuring security protocols, and creating middleware for efficient service communication. Each service functions as a discrete unit of functionality, facilitating a flexible and adaptable software environment.
