Hybrid Cloud For Dummies

Evaluating the Impact of Hybrid Cloud on Supporting Changing Network Requirements

Once you start moving your data into the cloud, you may need to address latency concerns, depending on the amount of data you’re storing there and how often you need to access it. In a hybrid model, you’re not just utilizing your LAN or WAN for data access, you’re now going across the Internet to access it. So, you really need to think about the kind of data you’re willing to store in the cloud based on how often you need to get to it and the network speed that you’re dealing with. Although storage may be unlimited (for a price) in the cloud, the network is not. Two issues you need to consider are amount of data and network speed.

Amount of data

Say that you want to store a large amount of tier 3 data in a storage cloud provider. It may not make sense to actually try to transport the data over the Internet. Remember, the bandwidth of a truck is greater than any existing network. It might make sense to provide the data to the vendor in another way. Calculate transfer rates based on the amount of data you have and then decide which leads to the next point regarding network speed.

Network speeds

Bandwidth is just one element that contributes to network speed. Latency is another one. Latency refers to a delay in processing data as it moves from one part of a network to another. For example, when a singer’s mouth moves on a video but the words don’t seem to match, that’s because of latency. Low latency ...
