Service integration and management (SIAM) emerged from its roots in the ITIL community as an adjunct to large-scale infrastructure outsourcing. While SIAM is an adequate — if cumbersome — approach to integration for ITIL-based "towers," it fails to support emerging cloud solutions. To fulfil their ambitions as service integrators and brokers, infrastructure and operations (I&O) technology managers must look beyond SIAM while accepting that the prospect of a converged tool set that encompasses both SIAM and cloud is still some way off.
