Administración avanzada de sistemas informáticos


Book Description

Actualmente, las empresas precisan de sistemas informáticos seguros y fiables, siendo fundamentales para su modelo de negocio. Es una escena habitual que las organizaciones trabajen y produzcan en base a los servidores y datos de los que disponen, y que el éxito final de su modelo de negocio dependa de cómo sus servicios son informatizados. Las tecnologías de la información se han convertido, con el paso de los años, en un elemento clave para la competitividad de las organizaciones. Es por ello que los requisitos necesarios para los servicios considerados “críticos” han sido redefinidos, demandando características más exigentes: gran velocidad, mayor eficiencia, alto rendimiento y alta disponibilidad. El objetivo es que el cliente acceda a los servicios y datos de una forma rápida e ininterrumpida. El objetivo de esta obra es introducir al lector de una forma teórico-práctica a las tecnologías y procedimientos necesarios para abordar con garantías los exigentes requerimientos que los sistemas informáticos presentan en el mercado actual: gran velocidad de respuesta, trabajo eficiente, alto rendimiento, alta disponibilidad, etc. Tenga en cuenta que, como administrador de los servicios de una empresa, se exigirá que estos se encuentren en correcto funcionamiento 24 horas al día, 7 días a la semana, 365 días al año. A lo largo del libro se dará a conocer de forma sencilla, práctica y mediante numerosos ejemplos, cómo sacar partido a las soluciones existentes basadas en GNU/Linux que permiten dotar de alta disponibilidad y alto rendimiento a los datos y servicios críticos de los sistemas informáticos de una empresa. Además, se profundizará en una de las tecnologías más populares y en expansión, a día de hoy, en el campo de la administración avanzada: la virtualización. La virtualización se está empezando a convertir en un aspecto clave y necesario para optimizar al máximo los recursos disponibles y el rendimiento de los servidores disponibles, así como para reducir costes, simplificar y mejorar las políticas administrativas de nuestra infraestructura informática. Temas incluidos: Aspectos básicos. Hardware del servidor, sistemas RACK, unidades NAS, sistemas RAID, etc. Alta disponibilidad y alto rendimiento.

Glosario Del Banco Mundial


Book Description

This edition of the World Bank has been revised and expanded by the Terminology Unit in the Languages Services Division of the World Bank in collaboration with the English, Spanish, and French Translation Sections. The Glossary is intended to assist the Bank's translators and interpreters, other Bank staff using French and Spanish in their work, and free-lance translator's and interpreters employed by the Bank. For this reason, the Glossary contains not only financial and economic terminology and terms relating to the Bank's procedures and practices, but also terms that frequently occur in Bank documents, and others for which the Bank has a preferred equivalent. Although many of these terms, relating to such fields as agriculture, education, energy, housing, law, technology, and transportation, could be found in other sources, they have been assembled here for ease of reference. A list of acronyms occurring frequently in Bank texts (the terms to which they refer being found in the Glossary) and a list of international, regional, and national organizations will be found at the end of the Glossary.




Good Boss, Bad Boss


Book Description

Now with a new chapter that focuses on what great bosses really do. Dr. Sutton reveals new insights that he's learned since the writing of Good Boss, Bad Boss. Sutton adds revelatory thoughts about such legendary bosses as Ed Catmull, Steve Jobs, A.G. Lafley, and many more, and how you can implement their techniques. If you are a boss who wants to do great work, what can you do about it? Good Boss, Bad Boss is devoted to answering that question. Stanford Professor Robert Sutton weaves together the best psychological and management research with compelling stories and cases to reveal the mindset and moves of the best (and worst) bosses. This book was inspired by the deluge of emails, research, phone calls, and conversations that Dr. Sutton experienced after publishing his blockbuster bestseller The No Asshole Rule. He realized that most of these stories and studies swirled around a central figure in every workplace: THE BOSS. These heart-breaking, inspiring, and sometimes funny stories taught Sutton that most bosses - and their followers - wanted a lot more than just a jerk-free workplace. They aspired to become (or work for) an all-around great boss, somebody with the skill and grit to inspire superior work, commitment, and dignity among their charges. As Dr. Sutton digs into the nitty-gritty of what the best (and worst) bosses do, a theme runs throughout Good Boss, Bad Boss - which brings together the diverse lessons and is a hallmark of great bosses: They work doggedly to "stay in tune" with how their followers (and superiors, peers, and customers too) react to what they say and do. The best bosses are acutely aware that their success depends on having the self-awareness to control their moods and moves, to accurately interpret their impact on others, and to make adjustments on the fly that continuously spark effort, dignity, and pride among their people.
