  1. A Summary of the Distributed System Concepts and Architectures Gayathri V.R. Kunapuli vkunapuli1@student.gsu.edu

  2. OUTLINE • Overview of Operating System basics • Transparency • Distributed System Services • Communication Network Protocols • Distributed Systems Major Design Issues • Distributed Computing Environment

  3. Overview of Operating System Basics • Definition of an Operating System • Functions • Components • Evolution of Operating Systems

  4. Definition of an Operating System • An operating system is the program that, after being initially loaded into the computer by a boot program, manages all the other programs in a computer. The other programs are called applications or application programs. The application programs make use of the operating system by making requests for services through a defined application program interface (API) and the users can interact directly with the operating system through a user interface such as a command language or a graphical user interface (GUI).

  5. Functions of an Operating System • multiplexing the processor(s) • scheduling processes • coordinating interaction among processes, interprocess communication and synchronization • managing system resources (I/O, memory, data files) • enforcing access control and protection • maintaining system integrity and performing error recovery • providing an interface to the users

  6. Components of an Operating System • Shell -Special application to facilitate User Interaction • Kernel -Software that contains core components of Operating System

  7. Typical OS components • Processor Scheduler • Memory Manager • I/O Manager • InterProcess Communication Manager • File System Manager

  8. Evolution of Operating System • 1. Centralized operating system: resource management and extended machine to support Virtuality • 2. Network operating system: resource sharing to achieve Interoperability • 3. Distributed operating system: a single computer view of a multiple-computer system for Transparency • 4. Cooperative autonomous system: cooperative work with Autonomicity

  9. OUTLINE • Overview of Operating System Basics • Transparency • Distributed System Services • Communication Network Protocols • Distributed Systems Major Design Issues • Distributed Computing Environment

  10. Transparency • Concealment from the user and the application programmer of the separation of components in a distributed system, so that the system is perceived as a whole than rather as a collection of independent components.

  11. Types of Transparencies • Access • Location • Migration • Failure • Replication • Concurrency • Performance • Parallelism • Scaling • Revision • Security • Persistence • Reocation

  12. OUTLINE • Overview of Operating System Basic • Transparency • Distributed System Services • Communication Network Protocols • Distributed Systems Major Design Issues • Distributed Computing Environment

  13. Distributed System Services • Access to I/O devices. • Controlled access to files • Program development • Editors and debuggers. • System access • Program execution • Error detection and response • Internal and external hardware errors • Memory error. • Device failure. • Software errors • Arithmetic overflow • Accounting • Collect usage statistics. • Monitor performance. • Apart from these, it also provides the Primitive Services, System Services and Value Added Services.

  14. OUTLINE • Overview of Operating System Basic • Transparency • Distributed System Services • Communication Network Protocols • Distributed Systems Major Design Issues • Distributed Computing Environment

  15. Communication Network Protocol • OSI Protocols • TCP/IP Protocol

  16. OUTLINE • Overview of Operating System Basic • Transparency • Distributed System Services • Communication Network Protocols • Distributed Systems Major Design Issues • Distributed Computing Environment

  17. Summary of Design Issues Issue • Communication, Synchronization, distributed algorithms • Process scheduling, deadlock handling, load balancing • Resource scheduling, file sharing, concurrency control • Failure handling, configuration, redundancy Affect Service • Interaction and Control • Performance • Resource • System Failures
