Other providers may have their own slightly different take in defining managed services but one thing is clear--it is outsourcing in its purest form, involving actual transfer of assets, that has indirectly spurred managed services. "The varying success of outsourcing and perceived loss of "control" has led to an emerging trend that outsources a task or capability, but not the asset itself," said Richard Moss, general manager, business continuity, security & governance practice, at BT Asia Pacific. "From this has emerged managed services".

Given the number of providers that are pitching what they define as managed services, it's no wonder that some enterprises are bewildered by the choice on offer.

Moss acknowledges there is no agreed industry definition of what a "managed service" is and many firms may well get a different definition if they talk to a communication service provider, network equipment manufacturer or customer. "Although there is some move towards common agreement on what constitutes a managed service, customers should ensure they, and any potential provider, speak the same language when engaging in this area," said Moss.

The uptake of managed services and outsourcing in Asia has yet to match the demand seen in the US and Europe but local incumbent carrier PCCW, sees growing momentum. "SMEs and mid-sized enterprises are keen on secure broadband services, plus other security functions like firewall and antivirus management, with larger firms eyeing a wider spectrum of offerings," said Larry Wong, director of marketing and products, commercial group at PCCW.

"Fighting security is a global challenge and qualified professionals and skills are not readily available in the market now," said Wong. "Customers are looking to leverage partners and providers to tackle network security."
