Control-Based Operating System Design describes the application of system- and control-theoretical methods to the design of computer operating system components. It argues that computer operating system components should not be first 'designed' and then 'endowed with control', but rather when possible conceived from the outset as controllers, synthesised and assessed in the system-theoretical world of dynamic models, and then realised as control algorithms. Doing so is certainly a significant perspective shift with respect to current practices in operating system design, but the payoff is significant too. In some sense, adopting the suggested attitude means viewing computing systems as cyber-physical ones, where the operating system plays the computational role, the physical elements are the managed resources, and the various (control) functionalities to be realised, interact and co-operate as a network. The book includes both a theoretical treatment of the usefulness of the approach, and the description of a complete implementation in the form of Miosix, a microcontroller kernel made available as free software.

Relational databases place heavy demands on their underlying hardware and many of these databases are mission-critical resources for multiple applications, where performance bottlenecks are immediately noticeable and often very costly to the business. Despite this, many database administrators are not very knowledgeable about server hardware. Many medium-to-large companies have completely separate departments that are responsible for hardware selection, configuration, and maintenance, and the DBA with no knowledge of hardware is often completely at their mercy. Likewise, many DBAs are also unaware of the performance implications of the various options and configurations for SQL Server, and the Operating System on which it is installed. Glenn Berry is a highly experienced Database Architect, teacher and SQL Server MVP, and his book is designed to provide the fundamental knowledge and resources you need to make intelligent choices about optimal installation and configuration of SQL Server hardware, operating system and the SQL Server RDBMS. With what you learn in this book, you'll be able to ensure that your SQL Server instances can handle gracefully the CPU, memory and IO workload generated by your applications, and that the operating system and SQL Server itself are installed, patched, and configured for maximum performance and reliability.

The first motivation for writing this book is to teach my colleagues about RTOS (Real-Time Operating System) concepts and the proprietary RTOS developed for our project by me. I realized that the same material with some extension can be useful to most embedded engineers who are beginners in learning about RTOS. I came across many embedded engineers who are not comfortable to use real-time operating system. A significant fraction of these people have taken operating systems course during their undergraduate or graduate studies The unease obviously even more aggravated for those embedded engineers who do not take operating systems course during their college level studies. I think this is the main reason that some companies still use tricky, messy workarounds to solve their scheduling problems in their simple and moderately complex projects. The operating systems course the engineers studied during their undergraduation is too broad which only cover theoretical aspects of all kinds of systems, and mostly devoid of practical training that students can not gain the ability to develop one
RTOS market share surveys show a significant fraction of companies use their proprietary operating systems. The proprietary RTOS has the advantages of leanness, higher efficiency and much more configurability as it is entirely open. Even though the market share for proprietary RTOS is slowly declining, the fraction of the companies that use proprietary RTOSes will be significant for many more years. This book can be a great resource for the engineers who are developing and maintaining a proprietary RTOS for his/her company.
This book address the needs of the people who want to learn about RTOSand also those who want to develop one. This book gives in-depth understanding of RTOS, make the reader comfortable in understanding a code written using RTOS, make the reader comfortable using RTOS to develop a new piece of code. This book explains all basic RTOS concepts starting from scratch in detail. So a beginner or a person only with little experience with RTOS can significantly benefit from this book. This book discusses most of the RTOS concepts and implements them in a piece of code and develops one simple RTOS kernel, named as SROS (Simple Real-time Operating System). All the features for SROS kernel are developed one at a time in an evolutionary manner. So this book can also benefit an experienced person who wants to know more about RTOS kernel. As this book develop feature by feature in a piece meal fashion, this book can greatly benefit the people who want to develop a proprietary RTOS for their projects. As this book covers the kernel of RTOS and point out some short term projects a reader can do, this book can also be used by students who want to know about the kernel of RTOS and want to do some short term projects on RTOS.
This book introduces the RTOS concepts one by one and shows their implementations in C code, or pseudo C code together with ARM assembly code when C implementation is not possible (i.e. in case of Hardware Abstraction Layer functions). Every piece of code shown as example in this book has either C code or pseudo C code so readers with out the knowledge of ARM architecture and instruction set can also understand the functionality of the code easily. (The ARM code given in this book and CDROM is developed for ARM architecture V5 and tested on ARM9platform). Allover the book when we mention ARM processor, it means we are referring to an ARM core that implement ARM V5 architecture. The RTOS code developed in the book is named as SROS (Simple Real-time Operating System). The SROS kernel implementation is on similar lines to many commercially available RTOSes. The SROS kernel features are added chapter after chapter. At any level of development, SROS code available in the accompanied CDROM can be readily used in an ARM based system and can be ported easily to other processor platforms. SROS features are implemented incrementally so that user has the choice of using it at any level of complexity. SROS with minimal features provide minimum code, execution time overheads and vice versa. The code size and execution complexity of SROS is less in the initial version compared to the later version even after unused functions are removed by linker. The accompanied CD-ROM provides 2 versions of SROS which were incrementally developed and finished by the end of 2nd and 3rd chapters.
The author assumes that the reader is familiar with C programming, and simple data structure - linked lists. No knowledge about assembly programming of ARM processor is assumed, even though the accompanying CDROM provide the SROS implementation on ARM platform, which is auxiliary.
The readers of this book after reading it can have the comfort of working/evaluating any RTOS, can have the comfort of knowing the internals of RTOS, can use highly simple and optimal SROS without any royalties with the flexibility of customizations, or can develop a simple proprietary real-time operating system in a few days.

This book gives an overview of Cloud Computing and Virtualization. It discusses the issues in Computational Resource Allocation and does an extensive experiments to evaluate the performance of web servers hosted on virtual operating systems. As multiple operating systems run on a single physical server, and multiple servers are running in the data center all connected via high speed network links, at some point of time, one of the servers may be overloaded, while others may remain underutilized. This poses challenges related to distributing the load and to carry out the work perfectly by using load balancing algorithm over the virtual machines. This book tries to find out the insights to balance the load based on computational time parameter of the virtual machines. We have also tried to evaluate and compare the performance of the web servers on different virtualization softwares including Xen, OpenVZ and Linux Operating Systems. It also discusses few algorithms related to resource allocation using control theory concepts and distributed computing algorithms.

The goal of workload modeling is to predict a computer's workload well enough to design it correctly. A poor model will lead to degraded performance and user satisfaction. Analyzing logs from multiple real parallel computers uncovers several statistical features - locality of sampling, daily cycles, weekly cycles, self similarity and flurries - that are missing from current workload models. Their practical importance is demonstrated by two new kinds of scheduling algorithms - adaptive scheduling and shortest job backfill first scheduling - which achieve an average 10% bottom- line performance gain and 35% stability gain on the production workloads. The second part of this book presents a user based workload model. It identifies four stable user types and five stable session types. It then deduces model parameters, the distributions of the arrival and activity patterns for both users and sessions, their dependencies and temporal structure. The methodology and statistical toolset is explained to make it easier to reuse in other domains. The insights and practical advice provided will be of use to anyone building or operating a large-scale parallel computer.

Who should read this book?

Whether you're completely new to web design, a seasoned pro looking for inspiration, or a developer wanting to improve your sites' aesthetics, there's something for everyone here.

How? Because instead of trying to cover every possible area of creating a web site, we've focused purely on the design stage; that is, everything that happens before a single line of code is written.

However, great design is more than just aesthetics. Long before we open our graphics program of choice, we'll be conducting research, dealing with clients, responding to briefs, sketching out sitemaps, planning information architecture, moving from doodles to diagrams, exploring different ways of interactivity, and building upon design traditions.

But ultimately, you'll be finding out how to create web sites that look drop-dead gorgeous.

For any organisation to be successful in an increasingly competitive and global working environment, it is essential that there is a clear understanding of all aspects of the business. Given that no two organisations are exactly alike, there is no definitive understanding of exactly what these aspects are as they will depend on the organisation's nature, size and so on. Some of the aspects of the business that must be considered include: process models, process descriptions, competencies, standards, methodologies, infrastructure, people and business goals. It is important that these different aspects of the business are not only understood, but also that they are consistent and congruent with one another. The creation of an effective Enterprise Architecture (EA) provides a means by which an organisation can obtain such an understanding. This book looks at the practical needs of creating and maintaining an effective EA within a twenty-first-century business through the use of pragmatic modelling. The book introduces the concepts behind enterprise architectures, teaches the modelling notation needed to effectively realise an enterprise architecture and explores the concepts more fully through a real-life enterprise architecture.
