    Study Notes

    Remote Procedure Call (RPC)

    • Extends the procedure call concept across process boundaries and memory spaces.
    • Supports both local and remote procedure calls, regardless of system location.
    • Key processes are marshalling (packing parameters) and unmarshalling (unpacking parameters).

    Distributed Object Frameworks

    • Enhances object-oriented programming by distributing objects over heterogeneous networks.
    • Facilitates coherent interactions as if objects were within the same address space.

    Examples of Distributed Object Frameworks

    • CORBA: Provides cross-platform and cross-language interoperability.
    • DCOM/COM+: Microsoft technology for distributed object programming preceding .NET.
    • Java RMI: Enables RPC between distributed Java objects.
    • .NET Remoting: Facilitates inter-process communication among .NET applications.

    Service-Oriented Computing (SOC)

    • Organizes distributed systems around services as fundamental building blocks.
    • Applications are formed through coordinated services within a Service Oriented Architecture (SOA).
    • Web services are commonly utilized to implement SOA and support cloud computing interactions.

    Distributed Computing Platforms

    • Middleware layer crucial for enabling distributed computing by providing a uniform runtime environment.
    • Rule-based systems, like Network Intrusion Detection Systems, utilize assertions and inference engines for data processing.

    Architectural Styles in Distributed Computing

    • Client/Server Model: Centralizes information and services, with multiple clients accessing a single server.
    • Peer-to-Peer Model: Symmetric architecture where all peers act both as clients and servers.

    Message-Based Communication

    • Involves components in networked systems sharing information by passing messages.
    • Messages can be remote procedure calls, serialized objects, or generic data packets.

    Distributed Programming Paradigms

    • Message Passing: Focuses on the message as a key abstraction for information exchange, with frameworks like MPI and OpenMP.
    • Remote Procedure Call (RPC): Allows procedure calls to invoke methods remotely.
    • Distributed Objects: Uses RPC principles within object-oriented contexts for method invocations across distributed systems.

    System Architectural Styles

    • Call and Return: Systems organized through method calls, categorized into:
      • Top-down style: Imperative programming.
      • Object-oriented style: Object programming models.
      • Layered style: Different abstraction levels implementation.

    Components of Distributed Systems

    • Need for effective inter-process communication (IPC) mechanisms and resource management.
    • Middleware layer allows applications to utilize distributed resources transparently.
