What is that thing with the cloud?
 
For Applications it‘s like  a virtual Multiusersystem Sorry, a WHAT?

Cloud in plain German

Editor's Notes

  1. Wir, die Leute aus IT und Web und Social Media können prima miteinander sprechen. Wir tun uns etwas schwer, wenn wir anderen etwas erklären wollen. Entweder es ist zu komplex, oder wir setzen Grundwissen über unser Fachgebiet voraus. Dann schreiben oder sprechen wir etwas, das unser Gegenüber gar nicht erreicht. Ich möchte hier ein Gespräch über dieses Cloud-Dingens wiedergeben. Im QR-Code steht: Jörg Thoß http://twitter.com/jthos Following Web Content where ever it lives. Connecting Content Management & Social Media for #OpenText
  2. Ich war neulich nach langer Zeit mal wieder auf einem Langstreckenflug. Neben mir saß keine Schnarchnase, sondern ein 19jähriger, wirklich vielseitig interessierter Amerikaner. Er war noch nie in Continental Europe gewesen und freute sich auf den Urlaub mit seiner Mutter in Italien. Er hatte sein Smartphone dabei und wollte wohl auch später, nach dem Urlaub ein paar Bilder auf Facebook stellen.
  3. Irgendwann nach schon längerem Gespräch schaut er so aus dem Fenster – und sieht Wolken. You say that you are in Software, so can you tell me: What is that thing with the cloud?
  4. Weil die Websites alle sehr unterschiedlich groß sind, liegen oft viele verschiedene Websites auf einem Computer. Sie teilen sich den Platz gemeinsam. Die Großen wie NASA und CNN <Klick> mittlere z.B. von Vermont oder Porsche <Klick> bis zu kleinen von einer Firma für Bohrmaschinen von Deiner Schule. Quellen der Screenshots (15.5.11 19:50 UTC): http://edition.cnn.com/ http://www.fox.com/ http://www.nasa.gov/ http://www.schule-neudietendorf.de/galerie.htm http://www.bemali.de/index-Dateien/MeinePuppen.html http://www.autosalon-singen.de/ http://www.porsche.com/germany/models/?pc=GA-Brand http://www.holz-metall.info/shop1/okategorie251.htm http://www.bosch-professional.com/de/de/ocs/werkzeuge/101357/bohrmaschinen/ http://www.docmorris.de/startseite/ http://www.vermont.gov/portal/ http://www.facebook.com/
  5. In der Cloud geht das noch etwas weiter. Da gibt’s auch Applikationen. Und damit funktioniert das dann wie ein virtuelles Multiusersystem. Der 19jährige: Sorry, a what? <Klick> Bling! Wiedermal habe ich versucht, jemandem etwas mit meinen Begriffen zu sagen. Also kurz nachdenken und einen neuen Versuch starten…
  6. Manchmal braucht man total viel Computing Power (NASA News vom Mars Exploration Rover) Und dann auch noch sehr viele Daten (Amazon Bücher und Reviews und Electronics …) Und jetzt nimmst Du leistungsstarke Server im Netz Und da legst Du auch Deine Daten hin Du selbst brauchst dann nur noch einen simplen Notebook / Smartphone Genauso, wie die anderen 100, 100tausend, 100millionen Benutzer
  7. Das habe ich kurz mit ein paar Beispielen erklärt. Für den Vortrag hier sind noch ein paar Bilder dazugekommen.
  8. Kosten Konkretes Beispiel – Europäischer Telekommunikationsanbieter Fährt im Standard mit 72 CPUs auf ca. 1000 PV/sec = 3.600.000 PV in Peak Stunde
  9. Zeit / Flexibilität Konkretes Beispiel: Media-Kunde Installationsplanung über mehrere Wochen Realisiert: Identifikation der Service Module, Installation auf Virtuellen Umgebungen, Skalierung on Deman „ Kaufen, installieren, testen“ versus „Praktisch sofort Größe anpassen“ Einmal installiert kann die Größe (Leistung, Speicherplatz) schnell angepasst werden. Und zwar nach oben und nach unten. Genau dann, wenn es gebraucht wird.
  10. „ Server, Netzwerke, Installation“ oder „Bohrmaschinen“ Fokus auf das, was Du gut kannst (z.B. Bohrmaschinen bauen) Ach ja, so ganz nebenbei: das geht überall im Netz, mit praktisch jedem Browser Konkretes Beispiel: Große Versicherung (nicht Deutschland) Sehr kleines permanentes Team, Content-Verantwortliche, Betreuer  Komplett außerhalb: Infrastruktur, Applikationsbetrieb, Lizenzen, Wartung, Sicherheit
  11. „ Mein Administrator kann das“ oder „Experten sind am Werk“ Viren, Angriffe von Konkurrenten, Neidern, untermotivierten Mitarbeitern. Sicherheit so gut, wie die Leute, die jeden Tag damit umgehen. In der Cloud sind Vollzeit-Experten mit der Sicherheit beschäftigt. Cloud funktioniert nur, wenn Sicherheit gegeben ist – und wir alle daran glauben.
  12. Kleine Cloud/SaaS Spezialitäten www.nasa.gov 06.08.2011 19:30 UTC Messen von Suchvorgängen, Verweildauer, Ratings  Neue Ergebnis-Reihenfolge – abhängig von eigenem Surfverhalten Raw Results trotzdem verfügbar in der Source „Baynote“ zu sehen
  13. Kleine SaaS Spezialisten – in der Source „Baynote“ Messung der Artikelsuche, Betrachtung, Kauf, Rating Empfehlung von Artikeln zu aktuellem Artikel und eigenem Surfverhalten www.soliver.de 06.08.2011 21:30 UTC
  14. Kleine SaaS Spezialisten – in der Source „bazaarvoice“ Anbieten von Rating/Review Möglichkeiten Moderation in der Cloud Anzeige von Ratings/Reviews Messen & A/B Testing etc. ROI ermitteln www.cyberport.de 06.08.2011 21:45 UTC
  15. Probleme Standardisierung Cloud Systeme – Vertragslaufzeiten & Providerwechsel - libcloud Speicherort EU oder Außerhalb Rechtliche Einschränkungen Datenspeicherung auf getrennten Systemen Abhängigkeit von einem Provider Shell 4Mrd $ über 5 Jahre März 2008 EDS Desktop (Entwicklung Betrieb Sicherheit) Helpdesk T-Systems Datencenter (Server Daten Speicher) Application Hosting AT&T Kommunikation (Netzwerk, Telefon, Internet)
