You have decided on what they need. You may be right from the viewpoint of storage, but from the access point you could be way off the mark. A database's access speed is directly related to the disk locations of the various fields and structures. True you have given them storage at minimal cost to you, but what have you cost the customer? Do you even have a way of benchmarking the search times you have impacted? Do you truly understand the DBA's tasks and the amount of data they have to search? > > There are tools today that enable me to move data around between > different storage systems without the user noticing.

When you are moving data around, do you examine the lifetime of the storage, or do you know the level of urgency when when that particular piece of data is needed or how it should be accessed? These parameters are the areas I have had to deal with in corporate settings when some IT person decided I didn't know what I was doing, and was sure they knew better. > > For VM's this is great.

If the IP address changes, the tight binding of resources will be disturbed, and that will result in a web search to find the new location, rebuild the linkages, and what happens to the computation while that is going on? > > For networking it seems a bit cloudy yet how this will work out.

If you put my systems in the cloud will I be paid for their processing time? At what par value? I know that I am such a boor for pointing these things out, but without boors like me, where would we really be? -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
