  3. CCS

    Upstream messaging possible

    Permanent connection between servers
    – But Google keeps messages around a while

    XMPP instead of HTTP

    You cannot use it right away
    – You have to sign up for it

  9. Drawbacks

    XMPP is less known than HTTP

    Less information online about XMPP

    I have found only one maintained Java lib

    Less information online about CCS

    Manual ACK / NACK handling

    Proxy servers can be an issue

    No Cloud Services support (as of yet)
    – Not even Google App Engine!

  10. Recommendation

    It's beta, so stay calm :-)

    Ideal for sending out many messages

    To a very large user base

    And for many return messages from device

    Do not trust the emulator!
