CORBA : What is CORBA in Distributed System ? : Distributed System
 
10:12
This Lecture will will cover the concept of CORBA in Distributed System. You will be able about CORBA , its architecture, working flow, application and features in easy way. Objective : To make better use of Distributed systems. To use object-oriented programming. To allow objects in different programming - languages to communicate with one another. CORBA(The Common Object Request Broker Architecture ) : The Object Management Group (OMG) was formed in 1989. CORBA is a standard defined by the Object Management Group (OMG) that enables software components written in multiple computer languages and running on multiple computers to work together (i.e., it supports multiple platforms). The object request broker (ORB) enables clients to invoke methods in a remote object. CORBA is a mechanism in software for normalizing the method-call semantics between application objects residing either in the same address space (application) or remote address space (same host, or remote host on a network). CORBA use an Interface Definition Language (IDL), ‘To specify the interfaces which objects represent to the outer world. CORBA then specifies a mapping from IDL to a specific implementation language like C++ or Java. CORBA implementation comes with a tool called an IDL compiler which converts the user's IDL code into some language-specific generated code. A traditional compiler then compiles the generated code to create the linkable-object files for the application. Working Flow of CORBA Architecture : ORB core It carries out the request-reply protocol between client and server. It Provide operations that enable process to be started and stopped. It Provide operations to convert between remote object references and strings. Object Adapter (server) Bridges the gap between CORBA objects and the programming language interfaces of the slave classes. Creates remoter object references for the CORBA objects Dispatches each RMI to the appropriate servant class via a skeleton, and activates objects. Assigns a unique name to itself and each object Called the Portable Object Adapter in CORBA 2.0 processes can run on ORB’s produced by different developers. Skeletons (server) An IDL compiler generates skeleton classes in the server’s language. Dispatch RMI’s to the appropriate servant class. Client Proxies / Stubs Generated by an IDL compiler in the client language. A proxy class is created for object oriented languages Stub procedures are created for procedural languages. Implementation Repository Activates registered servers on demand and locates servers that are currently running. Interface Repository Provides information about registered IDL interfaces to the clients and servers that require it. Optional for static invocation; required for dynamic invocation. Applications of CORBA: It is used as a RMI(remote method invocation) of a distributed client – server system. By using this, we can communicate with clients and servers on different operating systems and implemented by different programming languages (Java cannot do this). It is used in distributed applications. It is Ideal for a heterogeneous distributed system like the Internet. Important Points: Harder to use than a single language RMI such as JAVA. Compatible with various languages and operating systems. CORBA’s IDL is the crucial part because it permits communication on a heterogeneous distributed system. The OMG consists of several companies that maintain compatibility and standardization of the CORBA system. Features Of CORBA :   Language Independence: CORBA provides to its users the flexibility for programming language. Currently there are many languages supported by various CORBA providers, the most popular being Java and C++. There are also C, SmallTalk, Perl   OS Independence : CORBA's design is meant to be OS-independent. CORBA is available in Java (OS-independent), Linux/Unix, Windows, Sun, Mac ...etc.   Freedom from Technologies: The main benefit of CORBA is “ It normalize the interfaces between various new and legacy systems”. For example, a database wrapped by a server can have its database schema change for the sake of improved disk usage or performance (or even whole-scale database vendor change), without affecting the external interfaces. At the same time, C++ legacy code can talk to C/Fortran legacy code and Java database code, and can provide data to a web interface.   Strong Data Typing : CORBA provides flexible data typing, for example an "ANY" data type. CORBA also enforces tightly coupled data typing, reducing human errors. CORBA IDL (Interface Definition Language) provides the mechanism to ensure that user-code conforms to method-names, return-, parameter-types, and exceptions.   Freedom From Data Transfer Details: When handling low-level connection and threading, CORBA provides a high level of detail .

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In distributed computing, distributed objects are objects (in the sense of object-oriented programming) that are distributed across different address spaces, either in different processes on the same computer, or even in multiple computers connected via a network, but which work together by sharing data and invoking methods. This often involves location transparency, where remote objects appear the same as local objects. The main method of distributed object communication is with remote method invocation, generally by message-passing: one object sends a message to another object in a remote machine or process to perform some task. The results are sent back to the calling object. Distributed objects were popular in the late 1990s and early 2000s, but have since fallen out of favor. The term may also generally refer to one of the extensions of the basic object concept used in the context of distributed computing, such as replicated objects or live distributed objects. Replicated objects are groups of software components (replicas) that run a distributed multi-party protocol to achieve a high degree of consistency between their internal states, and that respond to requests in a coordinated manner. Referring to the group of replicas jointly as an object reflects the fact that interacting with any of them exposes the same externally visible state and behavior. Live distributed objects (or simply live objects) generalize the replicated object concept to groups of replicas that might internally use any distributed protocol, perhaps resulting in only a weak consistency between their local states. Live distributed objects can also be defined as running instances of distributed multi-party protocols, viewed from the object-oriented perspective as entities that have distinct identity, and that can encapsulate distributed state and behavior. Local and distributed objects differ in many respects. Here are some of them: 1. Life cycle : Creation, migration and deletion of distributed objects is different from local objects 2. Reference : Remote references to distributed objects are more complex than simple pointers to memory addresses 3. Request Latency : A distributed object request is orders of magnitude slower than local method invocation 4. Object Activation : Distributed objects may not always be available to serve an object request at any point in time 5. Parallelism : Distributed objects may be executed in parallel. 6. Communication : There are different communication primitives available for distributed objects requests 7. Failure : Distributed objects have far more points of failure than typical local objects. 8. Security : Distribution makes them vulnerable to attack. The RPC facilities of the cross platform serialization protocol, Cap'n Proto amount to a distributed object protocol. Distributed object method calls can be executed(chained, in a single network request, if needs be) through interface references/capabilities. Distributed objects are implemented in Objective-C using the Cocoa API with the NSConnection class and supporting objects. Distributed objects are used in Java RMI. CORBA lets one build distributed mixed object systems. DCOM is a framework for distributed objects on the Microsoft platform. DDObjects is a framework for distributed objects using Borland Delphi. Jt is a framework for distributed components using a messaging paradigm. JavaSpaces is a Sun specification for a distributed, shared memory (spaces based) Pyro is a framework for distributed objects using the Python programming language. Distributed Ruby (DRb) is a framework for distributed objects using the Ruby programming language.

Remoting Retrospective: DCE, COM, CORBA, RMI, RMI/IIOP, SOAP, REST, WebSocket

With WebSocket being the new kid on the block, it is useful to look back on the history of remoting to see what previous systems have done right and wrong. Because WebSocket gives full-duplex TCP abilities to any Web application, people will be building their own protocols on top of it. This BOF gives some perspective to those building such protocols.

Terry Benzel, CORBA Security Services and the Sigma Project (June 5, 1997)
 
42:41
From the CISR video library (http://www.cisr.us) Terry Vickers Benzel, Trusted Information Systems Inc. CORBA Security Services and the Sigma Project June 5, 1997 at the Naval Postgraduate School (http://www.nps.edu) ABSTRACT This talk will provide an introduction to the Security Services of the Common Object Request Broker Architecture (CORBA), and an overview of the Sigma research project. CORBA is an emerging standard for interoperable, object-oriented distributed computing that specifies an architecture for Object Request Brokers (ORBs), which enables diverse applications to interoperate in a uniform, platform-independent manner. ORBs hide platform and application differences with respect to programming language, operating system, networking capabilities, hardware, and object location, by transparently routing object method invocations to objects implemented by servers throughout a heterogeneous distributed computing system. The DARPA funded Sigma project is identifying and developing security mechanisms to be used for object-oriented distributed systems to provide security for interoperation within and between systems. Interoperability architectures and security mechanisms are being developed within the framework of CORBA. Government and military systems impose additional security requirements on distributed computing. Although interest in the use of CORBA technology in such systems is great, little consensus exists on how to proceed in a way that enforces security properly and with the required level of assurance. Although government and military systems often have significant high-assurance requirements and/or multilevel security requirements. The Sigma research project is developing proof of concept architectures which demonstrate the use of CORBA technology in such systems. About Terry Vickers Benzel Trusted Information Systems, Inc. Ms. Benzel id Director of TIS' Los Angeles office Advanced Research and Engineering Division. She has more than 15 years experience in R&D trusted systems. She is the project manager and chief architect for the DARPA-funded Sigma project, which is investigating CORBA security and interoperability for distributed systems. The project is exploring and prototyping security technology for control of distributed applications interoperating in large-scale heterogeneous computing environments based on CORBA. Additionally she provided trust engineering and multilevel security research on a variety of Rome Laboratory funded efforts and consulting contracts. Under subcontract to Hughes Aircraft, on the AF F-22 Program, Ms. Benzel provided trust engineering services for the design of the Common Integrated Processor of the on board Avionics System.
