CloudStor usage has increased exponentially

Alex ReidAlex Reid, Advisor to AARNet on eResearch, analysed all 500,000 records of CloudStor activity since its introduction in April 2010 and reports here on some of his findings:

Uptake of AARNet’s large file transfer service has been huge (as reported previously in AARNews) with exponential growth resulting in over 13,000 users within Australia’s research community using CloudStor by mid-2014.

Growth in traffic, and in file sizes, has also been enormous, with 175,000 files transferred in the 4 years to April 2014, amounting to an estimated total of 150 Terabytes by the end of 2014, and doubling every year. The spectacular growth in the number of files transferred (“uploaded”) can be seen in the chart above, which has extrapolated the figure for 2014.

Some of these findings were presented at the annual QUESTnet conference in Brisbane this month, and more will be revealed over the next few months.

Analysing the CloudStor data provides clues as to where traffic growth across AARNet has been arising, and also gives evidence of just how popular this service is proving to be.  In addition, it indicates that some institutions are not yet making much use of it, and also provides helpful insight into work patterns of researchers.

CloudStor was developed jointly by AARNet with European National Research Network partners Heanet (Ireland) and Uninett (Norway) and has also been implemented in 25 other countries, where it is known as FileSender.
