Titel: Cloud Computing: The Complete Cornerstone Guide to Cloud Computing Best Practices Concepts, Terms, and Techniques for Successfully Planning, Implementing … Enterprise IT Cloud Computing Technology

Autor: Ivanka Menken

Beschreibung:
„Everything you wanted to know about Cloud Computing but were afraid to ask. This book would be more appropriately titled „The Encyclopaedia of Cloud Computing.“ It covers just about every aspect of Cloud Computing you would be concerned about, from high-level overviews of the different technologies that might be appropriate for upper management, to a very nice series of „hands on“ chapters that walk you through experimenting with several of the Cloud Computing options.
Whether you need a quick primer on Cloud Computing so you can talk shop with those with more detailed knowledge, or want to get a sense of the benefits of the different technologies and how they fit into the big picture of the data center, this book is an invaluable resource. It gives you the vocabulary and understanding of how all the pieces fit together that websites and technical manuals often miss.

A must-buy comprehensive introduction. This book assumes you know nothing about Cloud Computing and quickly reviews some of the buzzwords that frequently get thrown around. It provides a detailed introduction to key topics including Options, and managing a Cloud Computing Project. For business analysts, there is an informative chapter on cost-benefit analysis and several chapters on best practices and pitfalls.

With energy costs, flexibility and scalability becoming a major factor in IT budgets, Cloud Computing will become even more widespread in the future. This is the best introductory book for practitioners and delivers a great overview of the complex world of Cloud Computing, it provides a broad and comprehensive view of the complex world of Cloud Computing, covering a large amount of territory. All of the major Cloud Computing technologies are discussed, along with the various drivers for implementing Cloud Computing, and how to manage migrating to a Cloud Computing environment.

What makes this book stand out from most other resources on the topic is its tone. You’re helpfully guided through the issues and tradeoffs in making a number of decisions on the what, where, when and how of Cloud Computing. This is extremely helpful for an IT manager who needs to come up to speed in a short period of time.

This book is a Well-written technical overview with a great business focus, it is written in a conversational style that contains very clear, succinct conceptual information and technical details interspersed with very pertinent and well-focused stories. The writing style and very well organized structural approach to the topics makes this book very readable by technology analysts, CIOs, and technical project managers who need to be able see the big picture of the „forest through the trees“ in order to understand the total corporate ROI issues with Cloud Computing technology.

Conversely, the book is well suited to industry technologist and software engineers who want to obtain a quick basic working knowledge of the „detailed roots“ of Cloud Computing technology but otherwise would never have been exposed to the broader applicability and global consequences of this very fundamental approach.

The well-organized structure of the book as independent parts, each containing independent chapters, makes it possible to pick and chose what information or level of technical detail is of interest to the reader while still allowing for interrelated topics to be introduced in the proper logically dependent sequence. Chapters such as „Common Terminology“, „Companies involved in Cloud Computing“, „Why Cloud Computing?“, „Benefits of Cloud Computing“, „Cloud Computing Technologies“, „Components of Cloud Computing“, „Migration to Cloud Computing“ and „Contracts, Agreements and Legal Implications“ are precisely what CIOs, IT managers, and technologists need to know.“

Nachteile des Cloud Computing

Konstante Internetverbindung
Cloud Computing ist nur möglich, wenn eine Internetverbindung verfügbar ist. Da durch ergibt sich hiermit schon ein Single-Point-of-Failure.

Langsame Verbindungen
Um Cloud Computing akzeptal einsetzen zu können, bedarf es einer schnellen Internetverbindung. Es kann sonst sehr lange dauern, bis die Seiten in einem großen Dokument durchgesehen werden können.

Geschwindigkeitsprobleme
Trotz einer schnellen Internetverbindung können webbasierte Anwendungen langsamer sein als die auf dem lokalen System. Das liegt an der Zeit, die der Transfer benötigt, um die Daten zwischen der Cloud und dem Arbeitsplatzrechner auszutauschen.

Schutz der gespeicherten Daten
Beim Cloud Computing werden alle(!) Daten in der Cloud gespeichert. Dadurch ergeben sich natürlich die Fragen: Wie sicher ist die Cloud? Haben andere, möglicherweise unauthorisierte Benutzer Zugriff auf meine Daten?

Datenverlust durch die Cloud
Im Prinzip sind die Daten durch das Speichern über mehrere Server und Standorte hinweg redundant vor Verlust geschützt. Sollten die Daten nun aber doch aus irgendeinem Grund verloren gehen, existiert kein physikalisches bzw. lokales Backup dieser Daten. Die Daten sind dann einfach weg. Das kann umgangen werden, indem regelmäßig Backups aus der Cloud auf einen lokalen Rechner abgelegt werden, was aber nicht im Sinne des Cloud Computings wäre.

Abhängigkeit
Unternehmen machen sich zunehmend abhängig von ihren Dienstleistern. Wurden Teile der Infrastruktur einmal in die Cloud migriert, ist der Weg zurück nicht mehr so einfach. Die Dienstleister bieten Utilities um die Daten vom Unternehmen in die Cloud zu vereinfachen. Programme um die Daten wieder aus der Cloud heraus zu migrieren existieren aber bisher noch nicht. Genau so wenig existieren Programme um die Daten zwischen unterschiedlichen Anbietern zu übertragen, was daran liegen mag, dass jeder Anbieter mit unterschiedlichen Standards arbeitet. Da bleibt die Frage offen: Einmal Cloud – immer Cloud bzw. immer dieselbe Cloud?

Buch – The Big Switch: Rewiring the World, from Edison to Google

Titel: Cloud: The Big Switch: Rewiring the World, from Edison to Google

Autor: Nicholas Carr

Beschreibung:
„While it may seem that we’re in the midst of an unprecedented technological transition, Carr (Does IT Matter?) posits that the direction of the digital revolution has a strong historical corollary: electrification. Carr argues that computing, no longer personal, is going the way of a power utility. Manufacturers used to provide their own power (i.e., windmills and waterwheels) until they plugged into the electric grid a hundred years ago. According to Carr, we’re in the midst of a similar transition in computing, moving from our own private hard drives to the computer as access portal. Soon all companies and individuals will outsource their computing systems, from programming to data storage, to companies with big hard drives in out-of-the-way places. Carr’s analysis of the recent past is clear and insightful as he examines common computing tools that are embedded in the Internet instead of stored on a hard drive, including Google and YouTube. The social and economic consequences of this transition into the utility age fall somewhere between uncertain and grim, Carr argues. Wealth will be further consolidated into the hands of a few, and specific industries, publishing in particular, will perish at the hands of crowdsourcing and the unbundling of content. However, Carr eschews an entirely dystopian vision for the future, hypothesizing without prognosticating. Perhaps lucky for us, he leaves a great number of questions unanswered.

Vorteile des Cloud Computing

Geringere Kosten für Arbeitsplatzrechner
Für die Nutzung von Cloud Computing Applikationen werden keine leistungsfähigen Arbeitsplatzrechner mehr benötigt. Die Anwendungen befinden sich in der Cloud und nicht mehr lokal auf dem Computer und werden über einenWebbrowser bedient. Dadurch ist eine hohe Rechenleistung und Speicherplatz auf dem lokalen System nicht mehr notwendig.

Leistungssteigerung
Das Arbeiten mit lokalen Systemen wird durch die Nutzung von Cloud Computing Anwendungen beschleunigt. Die Software und Daten der Anwender werden nicht mehr lokal gespeichert, wodurch das System entlastet wird.

Geringere Kosten der IT-Infrastruktur
Unternehmen können darauf verzichten in eine Vielzahl eigener leistungsstarker Server zu investieren und stattdessen die Rechenleistung etc. aus der Cloud beziehen. Interessant ist dies vor allem für Unternehmen, die saisonale Hochzeiten ausgleichen müssen und aus diesem Zweck ihre Systeme überdimensionieren müssen.

Geringere Instandhaltungskosten
Durch die Reduzierung der eigenen Serverfarm sinken die Instandhaltungskosten. Die Instandhaltungskosten der Software entfallen praktisch komplett, da dieses durch einen externen Anbieter übernommen wird.

Geringere Kosten für Software
Anstatt für jeden Arbeitsplatz einzelne Softwarepakete zu kaufen, besteht die Möglichkeit nur diejenigen Mitarbeiter die Software in der Cloud nutzen zu lassen, die diese auch benötigen. Selbst wenn die Kosten einer webbasierten Anwendung im Vergleich zu herkömmlicher Software gleich wären, würde die IT-Abteilung durch fehlende Installation und Wartung der webbasierten Software Kosten einsparen können.

Software Updates on Demand
Webbasierte Anwendungen können zentral und praktisch auf die Minute ausgetauscht werden. Die Software ist zu jeder Zeit auf dem aktuellen Stand, egal wann der Benutzer sich anmeldet.

Höhere Rechenleistung
Durch den Einsatz von Cloud Computing haben Unternehmen zu jeder Zeit den Zugriff auf die gesamten Ressourcen der Cloud und sind nicht mehr auf die Geschwindigkeiten beschränkt, die ihr eigenes Rechenzentrum ihnen bietet. Dadurch haben sie die Möglichkeit ihre Daten wie von einem Supercomputer verarbeiten zu lassen.

Unbegrenzter Speicherplatz
Im Vergleich zu einem Arbeitsplatzrechner oder einem Storage in einem Rechenzentrum ist der Speicherplatz in der Cloud praktisch unbegrenzt. Unternehmen haben dadurch den Vorteil ihren Speicherplatz dynamisch zu beziehen. Der angemietete Speicherplatz in der Cloud wächst also mit den Daten, die dort abgelegt werden.

Höhere Datensicherheit
Daten werden in der Cloud redundant (über mehrere Standorte) gespeichert, ein Datenverlust ist dadurch im Prinzip ausgeschlossen. Sollte ein Arbeitsplatzrechner abstürzen, sind die Daten davon nicht mehr betroffen. Lokale Datensicherungen können dadurch entfallen.

Einfachere Zusammenarbeit
Der klassische Dokumentenaustausch funktioniert so, dass die Daten auf einem Server im Netzwerk abgelegt oder per E-Mail an den Kollegen verschickt werden. Dabei konnte immer nur ein Benutzer zur Zeit an dem Dokument arbeiten. Durch das Ablegen der Daten in der Cloud können nun mehrere Benutzer – auch standortübergreifend – gleichzeitig auf ein Dokument zugreifen und dieses ebenfalls zur selben Zeit bearbeiten. Die Zusammenarbeit innerhalb eines Projekts wird dadurch verbessert.

Mobilität
Werden die Daten in der Cloud gespeichert, kann weltweit von jedem Ort, mit jedem Endgerät auf diese Daten zugegriffen werden – vorausgesetzt eine Internetverbindung ist vorhanden.
