Security is an essential requirement of any organisation when it
comes to financial account, customer and employee details.
Even though traditional on premise seems more secure as it is in-house,there are multiple measures that need to be taken to fully
maintain the security of the data.
SECURITY :                                                                                         With Cloud ERP systems there are very less chances of any hardware
software of infrastructure malfunction that can hinder the entire operation and
result in hefty losses.

hefty cost. Not just the initial investment, along with the purchase of
additional infrastructure and processes.
Comparatively, a cloud service is a lot more cost-effective,
especially those that are small in size. The setting up and run time is cheaper and
faster. Companies have to pay a nominal subscription fee whereby the updates
and maintenance by the cloud host.
