In the race to compete in today’s fast-moving markets, large enterprises are busy adopting new technologies for creating new products, processes, and business models. But one obstacle on the road to digital transformation is placing too much emphasis on technology, and not enough on the types of processes technology enables. What if different lines of business could build their own services and applications—and decision-making was distributed rather than centralized? This report explores the concept of a digital business platform as a way of empowering individual business sectors to act on data in real time. Much innovation in a digital enterprise will increasingly happen at the edge, whether it involves business users (from marketers to data scientists) or IoT devices. To facilitate the process, your core IT team can provide these sectors with the digital tools they need to innovate quickly. This report explores: Key cultural and organizational changes for developing business capabilities through cross-functional product teams A platform for integrating applications, data sources, business partners, clients, mobile apps, social networks, and IoT devices Creating internal API programs for building innovative edge services in low-code or no-code environments Tools including Integration Platform as a Service, Application Platform as a Service, and Integration Software as a Service The challenge of integrating microservices and serverless architectures Event-driven architectures for processing and reacting to events in real time You’ll also learn about a complete pervasive integration solution as a core component of a digital business platform to serve every audience in your organization.
Future requirements for computing speed, system reliability, and cost-effectiveness entail the development of alternative computers to replace the traditional von Neumann organization. As computing networks come into being, one of the latest dreams is now possible - distributed computing. Distributed computing brings transparent access to as much computer power and data as the user needs for accomplishing any given task - simultaneously achieving high performance and reliability. The subject of distributed computing is diverse, and many researchers are investigating various issues concerning the structure of hardware and the design of distributed software. Distributed System Design defines a distributed system as one that looks to its users like an ordinary system, but runs on a set of autonomous processing elements (PEs) where each PE has a separate physical memory space and the message transmission delay is not negligible. With close cooperation among these PEs, the system supports an arbitrary number of processes and dynamic extensions. Distributed System Design outlines the main motivations for building a distributed system, including: inherently distributed applications performance/cost resource sharing flexibility and extendibility availability and fault tolerance scalability Presenting basic concepts, problems, and possible solutions, this reference serves graduate students in distributed system design as well as computer professionals analyzing and designing distributed/open/parallel systems. Chapters discuss: the scope of distributed computing systems general distributed programming languages and a CSP-like distributed control description language (DCDL) expressing parallelism, interprocess communication and synchronization, and fault-tolerant design two approaches describing a distributed system: the time-space view and the interleaving view mutual exclusion and related issues, including election, bidding, and self-stabilization prevention and detection of deadlock reliability, safety, and security as well as various methods of handling node, communication, Byzantine, and software faults efficient interprocessor communication mechanisms as well as these mechanisms without specific constraints, such as adaptiveness, deadlock-freedom, and fault-tolerance virtual channels and virtual networks load distribution problems synchronization of access to shared data while supporting a high degree of concurrency
The unprecedented scale and demand of today's datacenter applications present tremendous challenges to the design of distributed systems. These systems need to handle the immense and unpredictable user traffic, remain highly available despite failures, keep data strongly consistent, and meet stringent service-level agreements (SLAs). Existing approaches, however, fall short in meeting these requirements: they require extensive server coordination to guarantee data consistency which leads to severe performance penalties, and they suffer from load imbalance in the presence of highly skewed workloads. This thesis proposes a new approach to designing distributed systems - co-designing distributed systems with the datacenter network. Specifically, we have taken advantage of new-generation programmable switches in datacenters to build several novel network-level primitives that offer strong guarantees. We then leveraged these primitives to enable more efficient protocol and system designs. Our key contribution is the design, implementation, and evaluation of three systems that demonstrate the benefit of this approach. The first two, Network-Ordered Paxos and Eris, virtually eliminate the coordination overhead in state machine replication and fault-tolerant distributed transactions, by relying on network sequencing primitives to consistently order user requests. The third, Pegasus, substantially improves the load balance of a distributed storage system. To achieve this, Pegasus selectively replicates the most popular objects, and tracks and manages the location of replicated objects using an in-network coherence directory implemented in the switch dataplane.
Designing a New Class of Distributed Systems closely examines the Distributed Intelligent Managed Element (DIME) Computing Model, a new model for distributed systems, and provides a guide to implementing Distributed Managed Workflows with High Reliability, Availability, Performance and Security. The book also explores the viability of self-optimizing, self-monitoring autonomous DIME-based computing systems. Designing a New Class of Distributed Systems is designed for practitioners as a reference guide for innovative distributed systems design. Researchers working in a related field will also find this book valuable.

Distributed Computer Control Systems 1982 focuses on the emerging trends in different areas on the use of computers. The text gives emphasis on computer programming, multiprocessor computer systems, and control systems that are considered important in the use of computers. The book presents various studies on how parallelization can affect the function of multiprocessor computer systems; the initiative being carried out by standardization groups involved in local area communication in improving distributed computer control systems; and how the sensor-base-management-system aids in distributed computer systems architecture. The text also presents studies on the analysis and development of protocols among distributed computer networks; how a distributed computer control system can efficiently work in a plant setting; and the problems associated with the design and implementation of this system and ways to solve them. The monograph is a great find for those who are involved and interested in computer engineering, computer programming, and in the design, implementation, and control of computer systems.

Although much has been made of the impact XML is having on Web development, the most significant changes brought about by XML have been in the way distributed systems store and exchange information. XML Distributed Systems Design offers in-depth architectural models for devising open-ended systems and provides templates for complex data interchange and mining theories as related to XML. XML Distributed Systems Design addresses core XML technologies such as XSL, DTD, XML Query, Data Warehouses, Data Mining, Distributed Systems Architecture, Web-based system design, Distributed Systems Framework, SOAP, SAX and using XML enabled tools for development and problem solving. Close attention is given to the way XML changes existing development patters and paradigms. In addition, the book presents the new patterns and strategies emerging in XML system design.
