The document discusses methods for getting data in and out of the cloud for email services and contacts/calendars between old and new systems. It notes that using standard interfaces like IMAP and standardized data formats like email made migration easier between services that both supported these. For more complex data, a lack of standards for interfaces and data formats would require ETL processes to deal with differences, and there is a risk over time that transformed data won't fully support the original data.

- 1. Getting data in and out of the cloud 24 th September 2009
- 2. What were we doing? Old email service $$$ New email service $ Mobile sync for contacts & calendar
- 3. How did we do it? Old email service New email service IMAP client Export Import
- 4. 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
- 5. 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
- 6. 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
- 7. Thank you for listening Grab me during a break or the networking session if you have questions
