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. In these systems, there is a single system wide primary memory (address space) that is shared by all the processors. (from GPS). Challenges • Heterogeneity • Openness • Security • Scalability • Failure handling • Concurrency • Transparency. Many are downloadable. Architectural models • An architectural model of a distributed system first simplifies and abstracts the functions of the individual components of a DS and then it considers: • The placement of the components across a network of computers • The interrelationships between the components.

Design issues of distributed system – Heterogeneity : Heterogeneity is applied to the network, computer hardware, operating system and implementation of different developers. • Three Examples • The internet • An intranet which is a portion of the internet managed by an organization • Mobile and ubiquitous computing. Performance of communication channels • Communication performance is often a limiting characteristic. When the application complies with these concepts, it can easily withstand high loads, process thousands of requests per second, have all operations correctly made, and all messages successfully delivered. Reference Books: Distributed Systems: Concepts & Design, 4th ed. Architectural Design, Distributed Systems Architectures - . • Middleware: a software layer that provides a programming abstraction as well as masking the heterogeneity. Computer clock and timing event • It is impossible to maintain a single global notion of time. Though developers dream about achieving 100% availability, it can be very challenging and expensive. Thread Programming and Concurrency. They typically go hand in hand with Distributed Computing. • … The users of a true distributed system should not know (or care) on which machine (or machines) their programs are running, where their files are stored, and so on. Difficulties and threats for distributed systems • Widely varying modes of use. This model, known as design model, is assessed for quality and reviewed before a code is generated and tests are conducted. • Two new security challenges: • Denial of service attacks (DoS). Download Teaching Slides for Chapter 17 Distributed Transactions. • Synchronizes each clock in the distributed system with a UTC source –clocks must be within drift bound D of UTC Internal synchronization: • Synchronizes the clocks in the distributed system with one another – any two physical clocks must be within drift bound D of one another • May drift from UTC but are synchronized together hoang huu hanh, hue university hanh-at-hueuni.edu.vn. • Open DS are based on the provision of a uniform communication mechanism and published interfaces for access to shared resources.

Concurrency • There is a possibility that several clients will attempt to access a shared resource at the same time. by Coulouris et al. When the application complies with these concepts, it can easily withstand high loads, process thousands of requests per second, have all operations correctly made, and all messages successfully delivered. Scalability • A system is described as scalable if it remains effective when there is a significant increase in the number of resources and the number of users.

The World Wide Web • The WWW is an evolving system for publishing and accessing resources and services across the Internet. 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. Mobil and ubiquitous computing • The portability of the devices, such as laptop computers, PDA, mobil phone, refrigerators, togather with their ability to connect conveniently to networks in different places, makes mobile computing possible. It should be clear by now that very few distributed systems are currently used in a production environ- ment.

Distributed Systems provides students of computer science and engineering with the skills they will need to design and maintain software for distributed applications. • Balancing computer loads • In some case load balancing may involve moving partially-completed work as the loads on hosts changes. This document is highly rated by students and has been viewed 1365 times. ... PPT. High availability means the percentage of time the service is operational. 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. • Techniques for dealing with failures: • Detecting failures • Masking failures • Tolerating failures • Recovering form failures • Redundancy. meng han. Systems Models and Programming 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). • Wide range of system environments • Internal problems: non-synchronized clocks, conflicting data updates, many modes of hardware and software failure involving the individual components of a system. • The Web is an open system: • Its oeration is based on communication standards and document standards tht are freely published and widely implemented. mr • Ubiquitous computing is the harnessing of many small cheap computational devices that are present in users’ physical environments, including the home, office and elsewhere. ‘ i ‘ K 7. • Throughput • The rate at which computational work is done. Fundamental Models • Interaction model • Failure model • Security model, Interaction model • Performance of communication channels • Computer clocks and timing events • Two variants of the interaction model • Agreement in pepperland • Event ordering.
