Getting data in and out of the cloud 24 th September 2009

What were we doing? Old email service $$$ New email service $ Mobile sync for contacts & calendar

How did we do it? Old email service New email service IMAP client Export Import

How could this be done better? Old email service New email service The direct route Export Import The long way ‘round IMAP client Export Import

This is of course a trivial example… but, Why did it work? Standardised interface IMAP Both services supported this interface, as did the client application The interface was bidirectional Standardised data format email Both services could parse the same data

Standardised interface

IMAP

Both services supported this interface, as did the client application

The interface was bidirectional

Standardised data format

email

Both services could parse the same data

If we were dealing with something less trivial Why wouldn’t it work? Lack of standardised interfaces Lack of standardised data format ETL(aaS) becomes a big deal to cope with impedance mismatches But… beware bitrot on Transformation. Target schemas may not support full range of import data set
