2 The IBM vision of a smarter home enabled by cloud technology Goodbye “smart.” hello “smarter.” Many consumers are already using cloud computing and A “smarter home” is on the horizon. The increasing number of may not realize it. Anyone who has a Web-based e-mail Web-enabled home appliances and devices, coupled with the account from Google or Yahoo!—or who has ever used widespread availability of broadband communications, are YouTube, Facebook or Twitter—has already interacted finally enabling new “intelligent” products and services that with data stored in the cloud.

Intelligent devices support the optimization of their use, both for the individual consumer and for the service provider. For instance, a utility can send signals to consumers’ homes to manage discretionary energy use in order to reduce peak loads. By coordinating this process throughout an entire service area, the utility can optimize the peak reduction, while saving the consumers money on their bill.

The adoption of smarter home devices requires that they alsoInstrumented devices in the home are connected to the cloud, be intuitive. Consumers will adopt new services only if they areenabling data to be aggregated and new intelligence to be created. easy to use and fit smoothly into their lifestyles. The learning curve for new services must be low to non existent, and the ben- efits of the services must be immediately apparent. Experience with services on the Web has shown that even minor changes in usability can have tremendous impact on consumer acceptance. Many current devices and appliances are well positioned to become smarter devices. Many appliances now enjoy an inter- nal CPU, sensors and instrumentation, and I/O ports. Yet the majority of these are accessed by technicians only during man- ufacturing or emergency repair field service. Adding the capabilities for a more permanent connection to the Internet is relatively easy and low in cost.Figure 1: Cloud computing provides an intelligent platform connectinginteroperating services with a common view of services in a home and Smarter home capabilitiesin the aggregate. The emerging capabilities of the smarter home enable services throughout many consumer industries, making consumers’ lives easier, healthier, more fun and more productive. The four service areas already demonstrating early adoption are: • Entertainment and convenience: The richness of the Internet is now available through the TV, which fundamentally shifts the definition of ‘content.’ Now consumer electronics companies can create open platforms for new lines of flat panel televisions that feature a portal which personalizes entertainment content from numerous broadcasters and movie studios. Over time, such devices might be subsidized by better targeted advertising, with a potential to share profits with other TV manufacturers with similar capabilities. This can lead to a win–win–win situation: reducing the number of commercials viewers have to watch, enabling broadcasters and advertisers to deliver more personalized entertainment options through targeted advertisements and giving TV manufacturers an opportunity to differentiate their products.

As the next step of the evolution of the SDP, it is being ported into the cloud. At the same time, the benefits of the proven concepts of service managements are extended beyond the telecommunications environment to any type of complex services involving large numbers of components and market players. Implementing the SDP concept in the cloud can revolutionize the ecosystem for the smarter home. The SDP is a platform to easily integrate component services, whether they are imple- mented with cloud technology or as conventional Web services. It makes possible the balancing of centralized and decentralized services and the use of existing back-end systems for functions such as customer relations management or billing.Figure 4: IBM Service Delivery Platform (SDP): An SOA-basedframework

14 The IBM vision of a smarter home enabled by cloud technologyThe emerging technology standardsOne challenge to the realization of the cloud-based smarterhome vision is the need to integrate a large number of deviceinterfaces, networking protocols and technologies and a varietyof applications and services already deployed in the home today.The IBM vision of a smarter home requires bi-directionalcommunication between home devices (appliances and automa-tion systems) and the cloud, a communication that can use anyhardware and networking technology.
