Questions and Answers

Which of the following best describes Service-Oriented Architecture (SOA)?

  • A way to make software components reusable using the interfaces
  • A stage in the evolution of application development and/or integration
  • An architectural approach in which applications make use of services available in the network (correct)
  • A network call over the internet to form applications

    • What is the main purpose of SOA?

  • To structure system development and integrate components into a coherent system

    Study Notes

    Service-Oriented Architecture (SOA)

    • SOA can be defined as a design paradigm that enables services to communicate over a network, promoting the reuse of software components.
    • The main purpose of SOA is to enhance the integration of disparate systems and applications, fostering agility and flexibility in software development.
    • In SOA, services are provided as discrete units that execute tasks or provide data, these units can be combined or reused across various applications.
    • SOA differs from microservice architecture primarily through its structural approach; while SOA organizes services into a larger enterprise-wide framework, microservices focus on developing smaller, independently deployable services.

    Role of Services in SOA

    • Services in SOA are designed to encapsulate business logic and system functionalities, allowing for easier access and integration between various services within the architecture.

    Web Services in Cloud Computing

    • A web service in cloud computing is an interoperable software system designed to support machine-to-machine interaction over a network, accessing specific functions or data through standard protocols.
    • The primary purpose of web services is to facilitate communication between different software applications, enabling them to work together seamlessly.
    • Web services can be utilized in software programs by allowing applications to send and receive data, often employing APIs to trigger and manage functionalities remotely.
    • The World Wide Web serves as the foundation for web services, enabling applications on different servers to connect and interact via standardized web protocols such as HTTP and XML.

    Similarities Between Web Services and Inter-Process Communication

    • Web services are analogous to inter-process communication in that both involve exchanging data between programs, though web services achieve this across different systems while inter-process communication occurs within a single computer environment.
