Cloud Computing: Public or Private?

Here are three factors to consider:

1. If you want wide access to a large range of IT tools with virtually no restrictions, you’ll probably want to go the public-cloud route. As when ordering at a cafeteria, you pick what you want and use the tech solutions as you need them, with no contractual obligations for use.

2. If you consider security a high priority, you’ll likely opt for a private cloud. The public cloud option, whether deservedly or not, still presents security concerns among IT managers.

3. A high-transaction, low-security business would probably prefer a public cloud, since volume and the need for access to the latest high-volume processing/monitoring tools would be high. Long delays on acquisition, implementation and integration would be avoided. Plus, the “pay as you go” public-cloud approach is more amenable to keeping purchases of big-ticket items in check.
