Despite this fall in revenues from the hardware division, Oracle has stuck to its strategy of replacing older legacy Sun hybrid (i.e.,both SPARC and x86) platforms with faster and high-margin upgraded SPARC servers and Oracle's Engineered systems. In its Q2FY14 earnings call Oracle reported double-digit growth in bookings for its Engineered systems' division, with triple-digit growth in revenues from the high-end SPARC SuperCluster line of servers. Strong demand for high-end servers arises from the growing need for faster provisioning of services. Globally, colocation hosting services are expected to cross $43 billion by 2018, from approximately $25.7 billion in 2013.
