Java in the Cloud

The cloud is one of those leading paradigm shifts that only happen every 10-15 years. Like other shifts before it (virtualization, offshoring, etc.), the cloud will profoundly impact the IT industry at large. No profession, no sector will remain shielded from the changes brought by the cloud.

Sacha Labourey, CEO of CloudBees and former CTO of JBoss, will first discuss how cloud computing is a natural step in the evolution and maturation of IT. He will then dig into what those changes mean for Java developers. Finally, he will discuss what choices Java developers are facing and will demonstrate what the future of Java developers might practically look like.

   When important paradigm shifts take place, it is hard to project
   yourself in the future…
   •
   But once you sit “on the other side” of the shift, the
   changes it brought with it seem obvious
   –
   Did someone/your kids ever ask you why phones
   used to have a cord?
   •
   What could be the impact of Cloud Computing on IT?
   And on developers’ jobs?
   Let’s go through a story you probably know very well…
   Beware, paradigm shift ahead!

   During the 19th century, the frst electrical generators
   appeared

   Some companies set up their own generators for their
   own use

   Complex, fragile, very costly

   Cities start investing in power plants

   At the end of the 19th century, the frst power plants
   emerge

   1878 – Exposition Universelle de Paris
   –
   1879 – St-Moritz (Switzerland)

   1882 – London & NYC

    No standards
    –
    AC? DC?
    –
    What frequency?
    –
    110V, 220V, 230V, 240V, other?
    –
    Plug? What plug?
    –
    Redundancy? SLA?
    Yet, this was not as simple as it seems…

    Directly managing your IaaS resources provides you with
    resource elasticity (CAPEX-free), but…
    O
    The amount of soft-IT typically required to do so is …
    higher!
    –
    All of the traditional IT activities remain
    (maintain/patch/monitor OS+JVM+AS+DB++, etc.)
    –
    + cloud-specifc items: elasticity/security/automation

    Could I please get a « Private PaaS »?

    Sure! We can also sell you a private jet!
    –
    Very tempting! All of the advantages but no decision about the cloud is needed!
    And I’ll be able to customize it!
    •
    Yes, but…
    –
    A great part of the value from a PaaS comes from the « S »: SERVICE
    • With a public PaaS, you are outsourcing your Operations & DevOps
    –
    With a Private PaaS you’ll get improve the« interface » between DEV and IT
    compared to traditional middleware, but … you remain in charge of all operations!
    –
    And remember: Customization is the root of all evil!

    The cloud is
    … not secure!
    … not stable!
    The real question is more probably:
    What will you do when a “loseIt!” will be a competitor in your feld?
    (hint: be that“LoseIt!”)
    “If you don’t like change, you are going to like irrelevance even less.”
