3 World s Data in Zettabytes Data growth
4 Data growth (1 zettabyte = 1 billion terabytes)
5 In 2008 In 2013 Typical server hard drive was 500GB with a transfer rate of 98 MB/sec Typical Server Hard Drive was 4TB with a transfer rate of 150 MB/sec An entire Disk could be transferred in 85 minutes An entire disk could be transferred in 440 minutes
6 $1.20 Average Price 1MB RAM $1.00 $0.80 $0.60 $0.40 $0.20 $
7 4000 CPU Speed in MHz
8 Disk capacities are getting bigger, but disks are not spinning faster Processors are not running much faster, but they have more cores RAM is becoming affordable
9 So To handle all of this new data we distribute it on clusters of computers Most modern analytical architectures take advantage of in-memory, distributed processing
