Big Data

How Big is Big Data?

Big data? Some say it starts with Petabytes which is 1000x of a terabyte. It can even be bigger! exabyte or bigger.

FB has about 0.5 PB of data a day. Avatar’s 3D effects were 1 PB.

How To Store Big Data

How do you store this much data? Your own machine? Well, SeaGate did just announce a 60TB single drive. If it’s bigger than that (or if you don’t have as big as computer), you’ll have to use a cluster of machine.

Concerns With Cluster

• How many machines to have?
• What happens if a computer dies? All of them will eventually.
• Should we back everything up?
