Although this is sort of IT 101, build an idea of
what it looks like to shut down an application that you either built or
are using as a service. This should include things like migration of
your data, and how you scrub important business data from the vendor's
servers.
This article
by Paul Venezia of InfoWorld explains the implications of exiting and
how one IT group ensures their data has been removed from a providers
servers. I don't think the author goes far enough because there are
most likely backups of your data on remote servers and possibly tape.
You should already know what your provider's retention policy is and
what form these backups are kept. If you have stand-by servers in
another data center, you may want to perform a wipe on those disks as
well before the storage space is released to other customers. I'll
assume that the backups on tape will eventually be destroyed and if
you've actually implemented with this provider, that you are OK with
their security policies that control access to backup media and their
disposal procedures.
