The private Cloud is just moving hardware into a datacentre, according to Fronde.
Australia country manager, Don McLean, said the advantage of the public Cloud is its multi-tenanted architecture where costs are shared across multiple customers.
"For instance, moving your ERP implementation from your office to a hosted, private solution means that your supplier has the same issues as you would have in your office" he said.
McLean said these issues typically include upgrade issues, maintenance of each server individually, and no consistent service.
When speaking of companies such as NetSuite and Salesforce, McLean said the public Cloud provides benefits such as a development platform to write further code particularly while still allowing upgrades to happen.
"Public means that one set of servers and databases are shared by many customers," he said.
Sharing of apps
A draw of the public Cloud for business is access to other applications through services, such as SuiteApps and Salesforce AppExchange, that are positioned as "low-cost but high-value."
"They can reduce the overall cost of ownership while increasing functionality, where you pay $5000 per year rather than $100,000 as a once-off programming assignment," McLean said.
As for the opportunity, McLean said there is value in developing software for the public Cloud that can be sold globally on app exchange sites.
"Develop local solutions on existing software that matches local solutions, such as banking software on an accounting system that is compatible with local banking standards for uploading to internet banking," he said.
Although the public Cloud is sometimes viewed as being less secure than the private one, McLean that is not necessarily the case.
"Private may be appropriate where you absolutely must lock everyone out of your system," he said.
