What is Integration?

    Fitting (not ramming) the round red peg into the
     square blue hole




    … good luck with that

    However, this has been done, and proven, outside IT

The Integration problem: your place or mine?




    We’re all hungry, but who gets to be the cook? Because
     every one will have to finish his plate – like it or not
    Not just a technical issue, but also a “political” one



                                                                Integration Core

The Integration trade-off: I speak yours if you speak mine




    Everyone must learn foreign languages

    Very costly, very time-consuming
    Impossible to become fluent in all, let alone a few
    No common single language

The Integration compromise: let’s speak a common language




    Everyone must learn only one foreign language

    Slightly less costly, less time-consuming
    Possible to become fluent in one language
    One common single language

The Integration solution: let’s hire an interpreter




    No one must learn a foreign language

    Least costly, least time-consuming
    One common single language
    Perfect fit-for-purpose for all
    Proven “technology”: European Parliament

European Parliament

    With currently 23 languages in the EP, there are 506
     (23 x 22) possible combinations
      That would be the integration trade-off in the flesh
    So, they use 3 middle languages: English, French,
     German
      (It’s that hard to be fluent in only two languages)
    Currently, 750 members serve for 5 years
      That means that on average
         12.5 people per month get
         replaced – seamlessly
    Can your IT landscape handle
     1.67% application replacements
     every single month?

The first solution: the ultimate trade-off


                                                                For every connected

                                                                to support N minus 1 non-
                                                                native interfaces. This is
                                                                killing if your landscape
                                                                grows, or has to change
                                                                (think upgrades)

The second solution: use the tools, Luke


                                                               For every connected
                                                               application N, one will have
                                                               to support 0 non-native
                                                               interfaces. Transformation
                                                               is done at a central hub, by

                      Don’t wait to adopt. The fittest adapt                              Resistance is futile
                                                                                             23-11-2011 12
The third solution: architects’ mistake


                                                              For every connected
                                                              application N, one will have
                                                              to support N non-native
                                                              interfaces. This is killing if
                                                              you replace an application
                                                              or introduce a new one, or
                                                              simply upgrade




    Enterprise Service Bus / Service Oriented Architecture
    Hard-coupled, synchronous
    Point-to-point connection to the Bus
    Enterprise effort: 0. App effort: n
                                                                                      Integration Core
                     Don’t wait to adopt. The fittest adapt                                Resistance is futile
                                                                                              23-11-2011 13
Three solutions. Did any of them solve anything?

    Point-to-point was okay but couldn’t scale. It still works
     for (very) small IT departments
    EAI was a great follow-up. Even introduced canonical
     model and messages, but the introduction of XML lowered
     the barrier so much that Integration quickly degraded from
     a profession to a pastime
    As a result, ESB got introduced and architects promoted it.
     At about the same time SOA saw the light, and now most
     (semi-)governments enforce very costly XML over HTTP

    And then… Google refuses to use XML, and Twitter and
     Facebook deprecate it in favour of JSON
    Hey – but XML was the language of the future!

    So maybe resistance wasn’t that futile after all?

                      Don’t wait to adopt. The fittest adapt       Resistance is futile

Picture yourself in an application’s place – from a business PoV

    Every single application in your
     landscape is carefully hand-picked
     and selected. You could compare
     each of them to Olympic athletes,
     specialised to perfection

    Highly single-minded, excelling at
     only one thing, they are at best
     average at most everything else

    But, you want to immediately replace
     them with the next best one
     whenever needed: there is no time-
     to-market

The Big Picture

    Any (leading) system needs to collaborate with(in) any
     existing IT-landscape, whether internal or external
    Any IT-landscape is diverse, and heterogeneous
     - and will always be. It’s an organic life-form in
     itself
    Evolution dictates that there will always be exceptions,
     differentiations. If a group becomes too large, individuals
     will arise out of it, forming new groups: standardisation
     never lasts long. Growth means change

    Application lifecycles get shorter every day. Spending
     time on development is a necessity, but on Integration?
    There is no business sense in expecting other
     organisations and applications to adopt; it is far more
     effective to make yourself adaptable
                                                                   Integration Core

One last word to the wise

    SOAP, WSDL, REST, W3C – all of those haven’t been
     mentioned. Nor need they be: they’re just narrow-minded
     opinions

    If you want to restrict yourself, your company and your
     customers and partners by limiting choices to either one of
     those, go ahead and do so – but try making a solid
     business case for that first, shall we?

    There is no one-size-fits-all, there are no Borg – well
     maybe there are, but they can be ignored. Certainly not
     feared

    You could debate the value of apples over oranges, but
     could you really, if this is the big picture?
                                                               Integration Core

  • 6. The Integration problem: your place or mine?  We’re all hungry, but who gets to be the cook? Because every one will have to finish his plate – like it or not  Not just a technical issue, but also a “political” one Integration Core Don’t wait to adopt. The fittest adapt Resistance is futile 5
  • 7. The Integration trade-off: I speak yours if you speak mine  Everyone must learn foreign languages  Very costly, very time-consuming  Impossible to become fluent in all, let alone a few  No common single language Integration Core Don’t wait to adopt. The fittest adapt Resistance is futile 6
  • 8. The Integration compromise: let’s speak a common language  Everyone must learn only one foreign language  Slightly less costly, less time-consuming  Possible to become fluent in one language  One common single language Integration Core Don’t wait to adopt. The fittest adapt Resistance is futile 7
  • 9. The Integration solution: let’s hire an interpreter  No one must learn a foreign language  Least costly, least time-consuming  One common single language  Perfect fit-for-purpose for all  Proven “technology”: European Parliament Integration Core Don’t wait to adopt. The fittest adapt Resistance is futile 8
  • 10. European Parliament  With currently 23 languages in the EP, there are 506 (23 x 22) possible combinations  That would be the integration trade-off in the flesh  So, they use 3 middle languages: English, French, German  (It’s that hard to be fluent in only two languages)  Currently, 750 members serve for 5 years  That means that on average 12.5 people per month get replaced – seamlessly  Can your IT landscape handle 1.67% application replacements every single month? Integration Core Don’t wait to adopt. The fittest adapt Resistance is futile 23-11-2011 9
  • 11. Next topic    History of Integration  How have problems been solved   Integration Core Don’t wait to adopt. The fittest adapt Resistance is futile 23-11-2011 10
  • 12. The first solution: the ultimate trade-off For every connected application N, one will have to support N minus 1 non- native interfaces. This is killing if your landscape grows, or has to change (think upgrades)  Point-to-point interfacing  Hard-coupled, synchronous  “Build once, modify never”  Enterprise effort: 0. App effort: n - 1 Integration Core Don’t wait to adopt. The fittest adapt Resistance is futile 23-11-2011 11
  • 13. The second solution: use the tools, Luke For every connected application N, one will have to support 0 non-native interfaces. Transformation is done at a central hub, by an Integration Broker  “Enterprise Application Integration”  Loosely-coupled, asynchronous  Integration as a profession  Enterprise effort: n2. App effort: 0 Integration Core Don’t wait to adopt. The fittest adapt Resistance is futile 23-11-2011 12
  • 14. The third solution: architects’ mistake For every connected application N, one will have to support N non-native interfaces. This is killing if you replace an application or introduce a new one, or simply upgrade  Enterprise Service Bus / Service Oriented Architecture  Hard-coupled, synchronous  Point-to-point connection to the Bus  Enterprise effort: 0. App effort: n Integration Core Don’t wait to adopt. The fittest adapt Resistance is futile 23-11-2011 13
  • 15. Three solutions. Did any of them solve anything?  Point-to-point was okay but couldn’t scale. It still works for (very) small IT departments  EAI was a great follow-up. Even introduced canonical model and messages, but the introduction of XML lowered the barrier so much that Integration quickly degraded from a profession to a pastime  As a result, ESB got introduced and architects promoted it. At about the same time SOA saw the light, and now most (semi-)governments enforce very costly XML over HTTP  And then… Google refuses to use XML, and Twitter and Facebook deprecate it in favour of JSON  Hey – but XML was the language of the future!  So maybe resistance wasn’t that futile after all? Integration Core Don’t wait to adopt. The fittest adapt Resistance is futile 23-11-2011 14
  • 16. Next topic      Future of Integration  How can problems stay solved Integration Core Don’t wait to adopt. The fittest adapt Resistance is futile 23-11-2011 15
  • 17. Picture yourself in an application’s place – from a business PoV  Every single application in your landscape is carefully hand-picked and selected. You could compare each of them to Olympic athletes, specialised to perfection  Highly single-minded, excelling at only one thing, they are at best average at most everything else  But, you want to immediately replace them with the next best one whenever needed: there is no time- to-market Integration Core Don’t wait to adopt. The fittest adapt Resistance is futile 23-11-2011 16
  • 18. The Big Picture  Any (leading) system needs to collaborate with(in) any existing IT-landscape, whether internal or external  Any IT-landscape is diverse, and heterogeneous - and will always be. It’s an organic life-form in itself  Evolution dictates that there will always be exceptions, differentiations. If a group becomes too large, individuals will arise out of it, forming new groups: standardisation never lasts long. Growth means change  Application lifecycles get shorter every day. Spending time on development is a necessity, but on Integration?  There is no business sense in expecting other organisations and applications to adopt; it is far more effective to make yourself adaptable Integration Core Don’t wait to adopt. The fittest adapt Resistance is futile 23-11-2011 17
  • 19. The real solution: facilitated canonical For every connected application N, one will have to support 0 non-native interfaces. Transformation is done at a central hub into one common language  Adaptive Integrated Enterprise  Fully de-coupled, asynchronous  Integration as a profession  Enterprise effort: n2. App effort: 0 Integration Core Don’t wait to adopt. The fittest adapt Resistance is futile 23-11-2011 18

  • 22. One last word to the wise  SOAP, WSDL, REST, W3C – all of those haven’t been mentioned. Nor need they be: they’re just narrow-minded opinions  If you want to restrict yourself, your company and your customers and partners by limiting choices to either one of those, go ahead and do so – but try making a solid business case for that first, shall we?  There is no one-size-fits-all, there are no Borg – well maybe there are, but they can be ignored.
