CentOS is the enterprise level Linux OS, which is 100% binary compatible to Red Hat Enterprise Linux (RHEL). It acts as a free alternative to RedHat's commercial Linux offering, with only a change in the branding. A high performance cluster consists in a group of computers that work together as one set parallel, hence minimizing or eliminating the downtime of critical services and enhancing the performance of the application.Starting with the basic principles of clustering, you will learn the necessary steps to install a cluster with two CentOS 7 servers. We will then set up and configure the basic required network infrastructure and clustering services. Further, you will learn how to take a proactive approach to the split-brain issue by configuring the failover and fencing of the cluster as a whole and the quorum of each node individually. Further, we will be setting up HAC and HPC clusters as a web server and a database server. You will also master the art of monitoring performance and availability, identifying bottlenecks, and exploring troubleshooting techniques.At the end of the book, you’ll review performance-tuning techniques for the recently installed cluster, test performance using a payload simulation, and learn the necessary skills to ensure that the systems, and the corresponding resources and services, are being utilized to their best capacity.

Budowanie produktów, które wnoszą realną wartość biznesową, wymaga dobrych podstaw. Takimi podstawami są wymagania. Inżynieria wymagań od lat stanowi podstawę projektów - niezależnie od panujących mód i trendów. Inżynieria wymagań to proces definiowania, dokumentowania i utrzymywania wymagań w projektowaniu inżynierskim. Bez inżynierii wymagań nie byłoby systemów - nie tylko informatycznych, ale także usługowych, z których korzystamy na co dzień. Windy, nowoczesne pralki czy telewizory, smartfony i aplikacje na nie, infrastruktura lądowa i powietrzna - wszystko to systemy budowane na podstawie wymagań. Bez inżynierii wymagań te systemy by nie powstały. Lub powstałyby... ale o nieakceptowalnym poziomie jakości. ze wstępu Książka obejmuje tematykę inżynierii wymagań według programu certyfikacji IREB® CPRE® Foundation Level na poziomie podstawowym. Omawia zagadnienia wyszczególnione w planie nauczania IREB® CPRE® z naciskiem na aspekt praktyczny, a także przygotowuje do egzaminu certyfikacyjnego. Co ważne, zagadnienia teoretyczne zostały zobrazowane przykładami w stopniu określonym przez poziom poznawczy (K1, K2, K3). Zdobądź certyfikat i stań się kimś, kogo nie ruszy żaden projekt: Opanuj zasady inżynierii wymagań Poznaj artefakty i praktyki dokumentowania Dowiedz się, jakie są praktyki w zakresie opracowywania wymagań Wdróż się w proces i strukturę pracy Zorientuj się, jak w praktyce wygląda zarządzanie wymaganiami Ułatw sobie zadania dzięki narzędziom wspierającym Podejdź do egzaminu próbnego (wewnątrz znajdziesz pytania egzaminacyjne, klucz odpowiedzi i ich uzasadnienia) Zobacz zapis z webinaru prowadzonego przez Karolinę Zmitrowicz oraz Rossa Apostola na temat: „Sztuczna inteligencja w produkcji oprogramowania” ⤵️ Zobacz zapis z webinaru prowadzonego przez Karolinę Zmitrowicz oraz Grzegorza Skrzyńskiego na temat: „Analityk biznesowy - zawód z przyszłością” ⤵️ Zobacz zapis z webinaru prowadzonego przez Karolinę Zmitrowicz oraz Aleksandrę Kunysz na temat: „Perspektywy Jakości - jakość postrzegana przez różne role projektowe” ⤵️
