Distributed operating system: It is different from multiprocessor and multicomputer hardware. Distributed system concepts . • Each message transmitted over a channel is received within a known bounded time • Each process has a local clock whose drift rate from real time has a known bound. Performance issues • Responsiveness • Users of interactive aplication require a fast and consistent response to interaction. Share yours for free! • Open DS are based on the provision of a uniform communication mechanism and published interfaces for access to shared resources. 2011.

Distributed Shared Memory Chapter 5 – Distributed Operating Systems; Concepts and Design By Pradeep K. Distributed Computing: Principles, Algorithms, and Systems, 1st ed. Topics. • Middleware: a software layer that provides a programming abstraction as well as masking the heterogeneity. • Independent failures • The programs may not be able to detect whether the network has failed or has become unusually slow. Download Teaching Slides for Chapter 20 Distributed Multimedia Systems. • No global clock • The only communication is by sending messages through a network. For a distributed system to work, though, you need the software running on those machines to be specifically designed for running on multiple computers at the same time and handling the problems that come along with it. High availability means the percentage of time the service is operational. Challenges • Heterogeneity • Openness • Security • Scalability • Failure handling • Concurrency • Transparency. Broad and up-to-date coverage of the principles and practice in the fast moving area of Distributed Systems. • Three Examples • The internet • An intranet which is a portion of the internet managed by an organization • Mobile and ubiquitous computing. Wikipedia defines the difference being that distributed file systems allow files to be accessed using the same interfaces and semantics as local files, not through a custom API like the Cassandra Query Language (CQL). Distributed Systems: Concepts and Design. • The problems of scale. • The implementation of the internet and the services that it suports has entailed the development of practical solutions to many distributed system issues. • Asynchronous distributed system • No bound on process executiong speeds • No bound on message transmisson delays • No bound on clock drift rates. • Controlling the performance loss. Mobil and ubiquitous computing (continue) • Mobile and ubiquitous computing raise significant system issues presents an architecture for mobile compuing and outlines the issues that arise from it, including how to support the discovery of resources in a host environment; eliminating the need for users to reconfigure their mobile devices as they move around; helping users to cope with limited connectivity as they travel; and providing privacy and other security guarantees to users and the environments that the visit. Dependability issues • The dependability of computer systems as correctness, security and fault tolerance. Computer clock and timing event • It is impossible to maintain a single global notion of time. 5. Failure handling • When faults occur in hardware or software, programs may produce incorrect results or they may stop before they have completed the intended computation.

Multiprocessor- uses different system services to manage resources connected in a system and use system calls to communicate with the processor. 2.

Because of this reason few firms had less number of computers and those systems were operated independently as there was a lack of knowledge to connect them. It is one of the most important characteristics of successful software. It extends from hardware components such as disks and printers to software-defined entities such as files, databases and data objects of all kinds.

Availability. • Quality of services • The ability to meet the deadlines of users need. Resource • The term ”resource” is a rather abstract one, but it best characterizes the range of things that can usefully be shared in a networked computer system. What is Distributed Systems. SCENARIOS FOR DISTRIBUTED ENERGY SYSTEMS AND NEW BUSINESS CONCEPTS - ’business as usual’. • The Web is an open system: • Its oeration is based on communication standards and document standards tht are freely published and widely implemented. George Coulouris, Cambridge University. Concepts and Design. Use of caching and replication • The performance issues often appear to be major obstacles to the successful deployment of DS, but much progress has been made in the design of systems that overcome them by the use of data replication and caching. advantages and disadvantages of distributed, Concepts and Models in Distributed Systems - .

Intranets • An intranet is a portion of the Internet that is separately administered and has a boundary that can be configured to enforce local security policies • The main issues arising in the design of components for use in intranets are: file services, firewalls, cost. Topics added to other chapters: Cloud computing, network virtualization, operating system virtualization, message passing interface, unstructured peer-to-peer, tuple spaces, loose coupling in … • The fundamental models – interaction, failure, and security – identify the common characteristics of the basic components from which distributed systems are constructed.

Each function or service that makes up an application may be executing on a different system, based upon a different system architecture, that is housed in a different geographical location, and written in a different computer language. Distributed File Systems: Design Comparisons - . Distributed Systems provides students of computer science and engineering with the skills they will need to design and maintain software for distributed applications. (see: “A Note on Distributed Computing”, Jim Waldo, et al.) Transparency • Transparency is defined as the 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 rather than as a collection of independent components. david hales www.davidhales.com the open university, uk design, Modern Distributed Systems Design – Security and High Availability - .

The nodes in the distributed systems can be arranged in the form of client/server systems or peer to peer systems. Event ordering • In many cases, we are interested in knowing whether an event (sending or receiving a message) at one process occurred before, after or concurrently with another event at another process. • Eight forms of transparency: • Access transparency ** • Location transparency ** • Concurrency transparency • Replication transparency • Failure transparency • Mobility transparency • Performance transparency • Scaling transparency.
