Projektowanie systemów rozproszonych. Wzorce i paradygmaty dla skalowalnych, niezawodnych usług
Brendan Burns
Nowoczesne oprogramowanie musi sprostać wyśrubowanym kryteriom: ma cechować się określoną niezawodnością i skalowalnością, a przy tym powinno korzystać z technologii chmury. Naturalnie powinien to być dobrze zaprojektowany system rozproszony. Dziś standardem jest korzystanie z aplikacji na wielu urządzeniach w różnych lokalizacjach. Niestety, mimo powszechności systemów rozproszonych ich projektowanie nader często przypomina coś w rodzaju czarnej magii, dostępnej dla nielicznych wtajemniczonych. W efekcie architektura każdego systemu jest unikatowa. Ta książka jest praktycznym przewodnikiem dla projektantów systemów rozproszonych. Zaprezentowano tu kolekcję powtarzalnych wzorców oraz zalecanych praktyk programistycznych, dzięki którym rozwijanie niezawodnych systemów rozproszonych stanie się bardziej przystępne i wydajne. Poza podstawowymi wzorcami systemów rozproszonych przedstawiono tu również techniki tworzenia skonteneryzowanych komponentów wielokrotnego użytku. Znalazło się tu także omówienie zagadnień rozwoju kontenerów i orkiestratorów kontenerów, które zasadniczo zmieniły sposób budowania systemów rozproszonych. Książka ta jest lekturą obowiązkową dla każdego projektanta aplikacji, który chce efektywnie budować niezawodne aplikacje rozproszone! Najważniejsze zagadnienia: wprowadzenie do systemów rozproszonych znaczenie wzorców i komponentów wielokrotnego użytku jednowęzłowe wzorce Przyczepa, Adapter i Ambasador wielowęzłowe wzorce dla replikowania, skalowania i wybierania węzłów głównych wzorce wsadowego przetwarzania danych na dużą skalę Twórz systemy rozproszone: skalowalne, elastyczne, niezawodne!
Projektowanie systemów wbudowanych w układach FPGA
Valery Salauyou, Adam Klimowicz
W książce omówiono zagadnienia projektowania systemów wbudowanych w układach FPGA, przy wykorzystaniu opisu w języku Verilog. Omówiono zastosowanie typowych bloków IP pamięci różnych typów: jednoportowych i dwuportowych pamięci typu RAM, ROM, FIFO, LIFO oraz rejestrów przesuwających. Omówiono kilka metod projektowania układów sterujących: w postaci automatu mikroprogramowanego z siecią działań, opartego na algorytmicznych automatach skończonych, a także na algorytmicznych automatach skończonych ze ścieżką przetwarzania danych. Rozpatrzono metodykę projektowania procesora jednocyklowego na FPGA, a także trzy metodyki projektowania procesorów wielocyklowych. Szczególny nacisk położono na testowanie implementacji procesorów i ocenę ich wydajności. Podano także zalecenia dotyczące zwiększenia wydajności procesora. Przedstawiono ogólną metodykę projektowania filtrów cyfrowych w układach FPGA, omówiono przykład opracowania filtra cyfrowego, pokazano symulację filtrów i implementację filtrów.

Puppet is a configuration management tool that allows you to automate all your IT configurations, giving you control over what you do to each Puppet Agent in a network, and when and how you do it. In this age of digital delivery and ubiquitous Internet presence, it's becoming increasingly important to implement scalable and portable solutions, not only in terms of software, but also the systems that run it. The free Ruby-based tool Puppet has established itself as the most successful solution to manage any IT infrastructure. Ranging from local development environments through complex data center setups to scalable cloud implementations, Puppet allows you to handle them all with a unified approach.Puppet 4 Essentials, Second Edition gets you started rapidly and intuitively as you’ll put Puppet’s tools to work right away. It will also highlight the changes associated with performance improvements as well as the new language features in Puppet 4. We’ll start with a quick introduction to Puppet to get you managing your IT systems quickly. You will then learn about the Puppet Agent that comes with an all-in-one (AIO) package and can run on multiple systems. Next, we’ll show you the Puppet Server for high-performance communication and passenger packages. As you progress through the book, the innovative structure and approach of Puppet will be explained with powerful use cases. The difficulties that are inherent to a complex and powerful tool will no longer be a problem for you as you discover Puppet's fascinating intricacies.By the end of the book, you will not only know how to use Puppet, but also its companion tools Facter and Hiera, and will be able to leverage the flexibility and expressive power implemented by their tool chain.
Puppet 8 for DevOps Engineers. Automate your infrastructure at an enterprise scale
David Sandilands, Nigel Kersten
As DevOps and platform engineering drive the demand for robust internal development platforms, the need for infrastructure configuration tools has never been greater. Puppet, a powerful configuration management tool, is widely used by leading enterprises and boasts a thriving open source community.This book provides a comprehensive explanation of both the Puppet language and the platform. It begins by helping you grasp the basic concepts and approach of Puppet as a stateful language, and then builds up to explaining how to structure Puppet code to scale and allow flexibility and collaboration among teams. As you advance, you’ll find out how the Puppet platform allows the management and reporting of infrastructure configuration. The book also shows you how the platform can be integrated with other tooling, such as ServiceNow and Splunk. The concluding chapters help you implement Puppet to fit in heavily regulated and audited environments as well as modern hybrid cloud environments.By the end of this book, you’ll have gained a solid understanding of the capabilities of both the Puppet language and platform, and you will have learned how to structure and scale Puppet to create a platform to provide enterprise-grade infrastructure configuration.
