  • Soorten wolken • Kale infrastructuur, bijvoorbeeld gegevensopslag, dit kun je bij Amazon vandaan halen, net zo makkelijk als een boek kopen; • Ingerichte platforms, bijvoorbeeld een .NET ontwikkelomgeving bovenop de infra van Amazon; • Applicaties, bijvoorbeeld SalesForce.com; • Gegevens, bijvoorbeeld Google Maps (hun applicatie op hun infra en platform en niet jouw gegevens maar hun gegevens).13
  • Infrastructure Platform Application Data Data Application Platform14 Infrastructure
  • Voordeel voor de business Situatie • ‘Steeds sneller veranderende wereld • Concurrentie voor zijn • Steeds minder tijd om voordeel te benutten • Sneller inspelen op kansen in de markt • Ook IT moet snel veranderen Voordelen van Cloud Computing • Sneller over middelen beschikken • Sneller vanaf • Vaak goedkoper (maar aanpassen aan de standaard)15
  • Gevolgen voor beheer Verschuiving naar beheer van interfaces Andere activiteiten • Zicht krijgen en houden op de markt van wolken • Contracteren • Configureren en integreren • De diensten consumeren; • Wijzigingen bewaken • Wolk en wolkleverancier monitoren Applicatielandschap steeds complexer en meer hybride Aangewezen op samenwerking met diversiteit van partijen Voor de klassieke applicatiebeheerder is dit eventjes wennen16

  • Capaciteitsbeheer• Aanbieding met Rentepunten van de Postbank• 50 euro Benzinebon voor de helft van de prijs• Om 9 uur mocht je de bon bestellen• Direct lag de hele site van de Postbank plat• Marketing Manager van de Postbank: “Die benzinebonnen waren een stuntje. Alleen dat onze website plat ging was een drama. Er was bij ons paniek in de tent. Wij hebben alleen al 29899 telefoontjes gekregen van boze klanten die belden. Onze medewerkers konden de boze reacties nauwelijks aan.”18

  • Sexy SOA• SOA is like teenage sex…• It is on everyone’s mind all the time• Everyone talks about it all the time• Everyone thinks everyone else is doing it• Almost no one is really doing it• The few who are doing it are: – Doing it poorly – Sure it will be better next time – Not practicing it safely• Everyone’s bragging about their successes all the time, although very few have actually had any 24

  • SOA - The Promise• SOA offers the promise of• Increased flexibility to support and facilitate organizations in their challenge to be more agile• Better integration of information from sources both within an organization and from external partners, thus supporting the whole business chain• Lower costs by more re-use of components26
  • SOA - The Downside• Loose coupling requires a large degree of maturity of the total SOA solution, including organizational aspects such as governance• Complex transition from existing IT to SOA• New and complex technology• Limited number of experts• Security and testing issues LoCoS27
  • Governance• University of Amsterdam: “Ownership of services within large service-oriented systems is not easy to address.”• To do: Define and monitor who takes decisions about what (ownership, accountability matrix) 28
  • Architecture• University of Amsterdam: “Without professionals who follow architectural principles and without management that implements architecture processes, SOA is doomed to fail.”• To do: Set generic principles and standards for all IT- systems and ensure adherence to them Monitor the consistency of the corporate information landscape (portfolio management) 29
  • Organization• Complexity of SOA-based systems• Number of parties involved• Lack of experience in management of these systems• Difficult to formalize• To do: Form a multidisciplinary team (extend the development team) until Service-Oriented Application Management can be ‘promoted’ to IT- as-usual 30

  • Bottom Line• SOA is new and promising• SOAM is even newer: new learning curve• More components, more parties involved: potential complexity explosion needs to be contained• Architecture and governance appear to be prerequisites• Extra competences: analysis, procurement, coordination• Application management adhocracy : multidisciplinary approach until SOAM can be formalized• To be continued…32

  • SamenvattingOmgeving van de business• Globalisering + meer informatie = machtsverschuiving naar consumentBusiness-organisaties• Vandaag presteren en morgen anders• Reputatie is erg belangrijk• Steeds afhankelijker van ITInformatiesystemen• Complexer: meer virtueel, hybride en gekoppeld met andere systemenIT organisaties• Kunnen verandersnelheid van business niet bijbenen• Ontberen kennis van bedrijfsprocessen en talent om gepast met business mensen om te gaan• Moeten intensief met anderen samenwerken – geen command & control maar communicate & collaborate34
