Jim,
We were, up until our recent migration, a PTC Cloud Services customer. They do a great job, especially since purchasing NetIDEAS a few years ago. We moved away from that service only because we were wanting to do things that couldn't be done cost effectively as a service.
For the company with the right set of requirements, they are a great solution. Just a couple of things that you might want to keep in mind.
- How are you getting your data into the system at the initial start up? Sending a HD full of files? Or inputting it all manually?
- How are you getting your data out of the system at the final shut down?
- What data are you getting out at the end? You might want to spell out that in addition to file vaults and database dumps and LDAP info, the configuration files and custom settings that were done are also exported if you are migrating to a different system.
