摘要：Data center colocation service offers businesses rental space infrastructure for equipment rack, network servers, cooling, power, physical security and internet bandwidth; with 24/7 technical supervision for close to 100% uptime promise. Enterprise in-house data centres are getting increasingly expensive to build and maintain. Many colocation providers also provide managed hosting services and Business Process Outsourcing among other services. Data centre operators face challenges from public cloud providers, and suggestions are being explored for opportunities. This paper presents 3 cloud deployment models; namely private cloud, public cloud and hybrid cloud. The three-layer model of cloud computing; namely Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS) is also introduced and briefly discussed. Colocation players with a global footprint are seeing the benefits of offering business platform which can adapt to customer demand and making the most out of the cloud deployment a model.
