For too long, IT has been thought of as a cost center, where the increased demands and shrinking budgets put it at odds with being responsive to new business requirements. The role of the CIO and IT as a whole has been in a state of flux - outsourcing, cloud computing (often in the form of stealth IT), and a heavy focus on reducing costs typically meant that infrastructure is aging and internal resources spend most of the time fighting fires and optimizing environments, at the cost of any new initiatives or enhancements. Now is the time for IT to take its place as a critical driver to business success by creating a modern data center. The authors of this book have real life experience as both IT practitioners and years of educating IT communities on transformational technologies.
Cloud technology is quickly becoming the default at companies of all sizes. Nine out of ten companies have already moved at least some of their applications or computing infrastructure to the cloud or plan to do so in the next 12 months. IT spending reflects this trend, with the average investment in cloud rising nearly 36% from two years ago. What's more, cloud adoption is growing across all delivery models, with examples of every kind of application and workload on every kind of platform, according to a recent IDG survey.
Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models.
Several technologies are rapidly evolving on a day-to-day basis but nothing can come closer to the transformation that cloud has gone through in the last few years. The important aspect of cloud is the fact that it has impacted all the facets of both business and professional life of people. Significance of cloud strategy has reached the extent where companies can no more play the waiting game.
Technological innovations are rapidly changing our lives, our businesses, and our economy. Technology, no longer an isolated business sector, is a facilitator enabling innovation, growth, and the strengthening of America's traditional business sectors. From transportation and energy to finance and medicine, businesses rely on technology to interact with their customers, improve their services, and make their operations more globally competitive. Innovative technology is deeply integrated into the economy and is the driving force behind the creation of new jobs in science, health care, education, transportation, and more. Technology has fundamentally transformed our economy—and is poised to fuel even more growth in the future.
