Asian business leaders beware -- your position as market leaders have never been at greater risk.

The time to decide is now if you are deciding on whether cloud right for your business. Take away businesses that are being stifled by conservative regulators, there are no businesses that could not be transformed by cloud computing.

The argument that only startups, new industry disruptors and tech-driven companies like telcos will be heavy cloud users is dead.

The state of Texas, the world's largest producer of carpets Shaw Industries Group, leading US kitchen and furniture retailer Williams Sonoma, are all running their critical business apps on the cloud.

CIOs, CFOs and CEOs of industry-leaders such as those above stood on stage at this year's NetSuite World conference and talked about how technologies from the cloud ERP/CRM provider had transformed their business or enabled them to venture to new markets at speeds and in ways not previously imagined.

For those that still say cloud computing is not fit for mission-critical applications in particular for large enterprises, take a look at how these businesses and organizations are changing their industry landscape with the cloud.

The government of Texas, the second largest in the US in population and in economic might with US$ 1.4 trillion in output in 2012 that would place it 13th in world GDP charts after Australia, has placed its whole procurement platform on the NetSuite cloud.

Every item that every agency purchases is processed via the cloud from pencils to cars and according to its CTO, "it's all about enabling the Amazon experience for the government."

Shaw Industries Group, founded in 1946 and a Berkshire Hathaway company last year made a bold expansion into Asia by running its whole ERP for international operations in the cloud. Warren Buffet only buys rock solid traditional businesses so this is no startup wannabe.

Shaw has opened a new 210,000-square-foot manufacturing facility in Nantong, China, and is also running 10 international subsidiaries in countries including China, India, Luxembourg, Hong Kong, Singapore and Australia.

Retailer Williams Sonoma also expanded rapidly into international markets on the back of leveraging NetSuite ERP and CRM in the cloud. Without the cloud, these business-changing initiatives would not have been possible at the required speed, cost and functionality.

For businesses in Asia, with the emergence of competitive threats from all angles, the need to seriously rethink the way they do business is critical.

As NetSuite's CEO declared to audiences earlier this month in San Jose, "the clean lines where a company used to operate within are no longer applicable, product companies are becoming services companies, retailers becoming software companies (amazon) and now even financial players."

He noted that more and more companies today are being born in the cloud and that cloud technologies will continue to change business models and business natures.

For those that say that cloud is not for them, think again would be the recommendation. Sure some will build out dynamic private clouds but only the very largest and most committed companies or the most regulated can realistically pursue that path. For the rest the choice is stark -- to the cloud or not, consume or be consumed.
