A cloud is not just a cloud. Just look up into the sky on any given day and you’ll notice a wide variety of sizes and unique characteristics that define each type. For example, there is the stratus variety. These clouds are very horizontal and are usually seen at lower altitudes. They often mean rain or snow, depending on the temperature. Cirrus clouds, on the other hand, are high-altitude clouds. They are thin and wispy and conjure up images of castles in the sky. Cumulus clouds are those fluffy, puffy, clouds that look perfect in a deep blue sky. They pile up like giant cotton balls and are common in the early afternoon on warm days. Cumulus clouds complete the perfect sky for a western movie’s panoramic shot.
There are other types of clouds that have nothing to do with the weather but are nevertheless just as common. For example, there is the private cloud, the public cloud, and the hybrid cloud. If you’re thinking about modernizing your data protection infrastructure, it’s hard not to consider any of these clouds as being just as important as the ones overhead. Do you know the difference between the clouds that can protect your data?

Advantages of the public cloud include little to no capital expenditure and speed of deployment. (more…)
