Cloud Environment Disk performance can be low. Cloud virtual machine storage caching does not really help. Using VeloRAM caching will allways help by reducing Disk Latency and Storage Bottleneck issues. VeloRAM High end performance RAM Cache accelerates Azure Cloud VM by 300% to 2100%.
See Examples 1-n below. physical machines generally behave similarly to modern virtual machines. Example 4 shows a 2011 physical PC with VeloRAM, its got an impressive 3600% acceleration with VeloRAM. Yes todays machines are faster, their score is around 50.000.
We found out with a detailed storage performance analysis of Cloud based Virtual machines. Cloud based VM´s have a slower Storage Latency than a Desktop PC. It is usually between 0.1 and 0.5 Milliseconds (Ms) for 1 Read Operation (IO) and 10 to 50 Milliseconds for 1 Write Operation.
Although they are connected to high performance storage arrays. VeloRAM has 6 Microseconds Latency, that is fastest in the Storage Indutry. VeloRAM is the cost effective solution to accelerate any Windows VM, in Cloud, Backend or home. VeloRAM relies on RAM for caching only and does not use any secondary storage like SSD. Usually Cloud based Virtual machines offer some small amount of temporary storage which can be based on SSD.
But this can not be used as performance reliable Cache medium. VeloRAM, as the name suggests, uses RAM to accelerate Disk I/O. It is allways available with best Latency and Bandwidth compared to any other storage.
